The Evaluation of the bond strength of different surface treatments in the repair of conventional resin with bulk-fill resin
Composite resin restorations are widely used in dentistry, and repairs with Bulk-fill resin offer advantages such as practicality and reduced clinical time. This study evaluated the bond strength of Bulk-fill resin repairs on conventional resin, considering different surface treatments. Fifty samples of Opallis composite resin (FGM) were fabricated in a metal mold (8×8×4 mm) and light-cured in 2 mm increments for 20 seconds each. After 10,000 thermocycling cycles, the samples were divided into five groups: AfA (phosphoric acid + adhesive), AfSA (phosphoric acid + silane + adhesive), PAfA (diamond bur + phosphoric acid + adhesive), PAfSA (diamond bur + phosphoric acid + silane + adhesive), and PSA (diamond bur + silane + adhesive). Repairs were performed using Opus Bulk Fill APS resin (FGM) in a mold of 8×8×8 mm and stored in distilled water at 37 °C for four weeks. The samples were subjected to a microtensile bond strength test. Statistical analysis (Kruskal-Wallis and Dwass-Steel-Critchlow-Fligner post-test) showed that the use of a diamond bur (PAfA: 11.3 MPa; PAfSA: 10.9 MPa; PSA: 14.7 MPa) resulted in higher bond strength, with a significant difference for the PSA group compared to groups without diamond bur treatment (AfA and AfSA). There was no significant influence from the isolated use of silane or phosphoric acid. It is concluded that surface treatment with a diamond bur combined with silane is recommended to optimize bond strength and increase the longevity of repairs with Bulk-fill resin.

Approaches to dental management of children with autism spectrum disorder (ASD)
Objective:To explore and synthesize evidence on effective behavioral, sensory, and technological interventions in the dental care of children with Autism Spectrum Disorder (ASD). Materials and Methods:A scoping review was conducted according to the PRISMA protocol. The search was performed in the PubMed, Scopus, and Web of Science databases. Studies evaluating behavioral strategies, sensory adaptations, and assistive technologies in dental settings for children with ASD were included. The selected articles were analyzed thematically, focusing on clinical outcomes and practical feasibility. Results: Out of 74 articles initially identified, 15 met the inclusion criteria. Behavioral interventions such as video modeling and social stories proved effective in reducing anxiety and enhancing patient cooperation. Sensory-adapted environments helped lower physiological and behavioral stress levels. Assistive technologies, including mobile applications, facilitated patient interaction and adherence to treatment. Structured protocols that combined caregiver training with visual pedagogy significantly improved cooperation during dental procedures. Conclusion:The analyzed interventions demonstrate the potential of personalized strategies to meet the specific needs of children with ASD, fostering inclusive and humanized oral healthcare. However, limitations such as small sample sizes and the absence of longitudinal studies highlight the need for future research to refine and validate these approaches across diverse clinical contexts.
University Students' Perception of the Knowledge Acquired in a Temporomandibular Joint Magnetic Resonance Imaging Course
Aim: To evaluate the perception of university students regarding the knowledge acquired in an interdisciplinary course on Magnetic Resonance Imaging (MRI) of the Temporomandibular Joint (TMJ). Methods: This is an analytical, observational, quantitative, and prospective study conducted with students from the Dentistry and Speech-Language Pathology undergraduate programs enrolled in a university extension course on TMJ MRI. Data collection was performed using two online questionnaires applied before and after the course, addressing topics such as anatomy, imaging planes, TMJ pathologies in MRI, and clinical correlation of findings. Responses were analyzed using statistical tests to compare pre- and post-course results. Results: A total of 52 students participated, with 32 answering the initial questionnaire and 20 completing the final one. A statistically significant difference (p=0.01) was observed in the students’ self-perceived knowledge after the course, indicating improvement across all evaluated domains, particularly in the identification of anatomical planes, disc displacement, and degenerative changes. Conclusion: The extension course, based on active and interdisciplinary teaching methodologies, contributed to improving students’ perception of their knowledge about TMJ MRI. Despite the positive results, it is important to note that the data are based on self-perception and a small sample size, highlighting the need for future studies involving objective performance assessments and larger, more representative samples.
Temporomandibular Joint Dysfunction Syndrome
ASSOCIATION BETWEEN THE SEVERITY OF TEMPOROMANDIBULAR DYSFUNCTION AND TRAIT-STATE ANXIETY LEVELS IN DENTAL STUDENTS
Introduction: Anxiety is an emotional experience related to the anticipation of future situations perceived by the individual as unpleasant. Health science students represent a specific group exposed to a high emotional burden, which creates space for the emergence of other conditions such as anxiety and temporomandibular disorder (TMD). Objectives: To investigate the association between the severity of temporomandibular disorder and trait-state anxiety levels among Dentistry students. Methodology: This is a cross-sectional, descriptive study with a quantitative approach, using a non-probabilistic convenience sample composed of 101 Dentistry students. To assess the signs and symptoms of temporomandibular disorder and anxiety, the Fonseca Anamnestic Index and the State-Trait Anxiety Inventory (STAI) were used, respectively. Data were recorded, tabulated, and analyzed using descriptive and inferential statistics. For the descriptive procedures, frequencies and percentages were presented; for inferential procedures, Chi-square, Fisher's exact test, and Student's t-test for numerical data were used. A significance level of p < 0.05 was considered. Results: No significant association was observed between the severity of TMD and trait anxiety levels (p = 0.143). However, a significant association was found between the severity of TMD and state anxiety levels (p = 0.006). Conclusion: The results demonstrated a significant association between the severity of TMD and state anxiety levels, indicating that more severe cases of the disorder may be linked to higher levels of situational anxiety among Dentistry students. Keywords: Temporomandibular Joint Dysfunction Syndrome; Anxiety; Students.

Protocolo de aplicação do diamino fluoreto de prata na avaliação da resistência de união de sistemas adesivos e cimentos de ionômero de vidro ao esmalte e Ã dentina previamente tratados: uma revisão de estudos laboratoriais
Introdução: O diamino fluoreto de prata (DFP) tem sido considerado como um dos mais efetivos tratamentos não invasivos de lesões de cárie cavitadas em dentes decíduos. Além disso, pelo efeito inibidor de enzimas proteolíticas, também tem sido sugerido durante procedimentos restauradores, a fim de aumentar a longevidade de restaurações. No entanto, parece não existir, até o momento, um protocolo padrão para a aplicação do DFP, em especial, Ã dentina. Objetivo: Identificar, por meio de uma revisão da literatura, o protocolo usual de aplicação do DFP em estudos laboratoriais que avaliaram a resistência de união de sistemas adesivos e cimentos de ionômero de vidro ao esmalte e Ã dentina. Metodologia: A busca por estudos elegíveis foi realizada nas bases de dados PubMed/MEDLINE, Web of Science e Scopus, até maio de 2025, sem restrição de idioma. Dois avaliadores realizaram a seleção dos estudos, considerando critérios de inclusão e exclusão previamente estabelecidos. Os dados de interesse foram coletados e analisados descritivamente. Setenta e cinco estudos foram incluídos na revisão, publicados majoritariamente nos últimos 5 anos e em língua inglesa. A maioria dos estudos avaliou o efeito do DFP aplicado Ã dentina alterada por cárie de dentes permanentes. Dez produtos comerciais Ã base de DFP nas concentrações de 3,8%, 12%, 30% e 38% foram utilizados nos estudos incluídos. A diversidade de protocolos de aplicação do DFP nos estudos laboratoriais considerados impossibilitou a identificação de um protocolo padrão, e desse modo, que um protocolo clínico seguro e efetivo fosse sugerido.

Laser acupuncture in the energetic regulation of temporomandibular dysfunction: a randomized control trial
The regulation of energy before clinical interventions can enhance therapeutic outcomes. While laser acupuncture has been shown as a complementary approach in dental care, no studies have assessed its potential to regulate energy in individuals with temporomandibular dysfunction (TMD). This study aimed to determine whether laser acupuncture promotes energetic regulation in patients with muscular-origin TMD. A blind, randomized clinical trial was conducted with 48 participants experiencing both energy imbalance and TMD-related pain. Subjects were distributed into four groups: acupuncture (A), laser (L), and their respective placebos, PA and PL. Group A received traditional acupuncture with needles; group L underwent low-level laser therapy; placebo groups had acupoints identified but without active stimulation. The Ryodoraku device, which evaluates 24 acupuncture points on the 12 meridians, was used to measure energy levels to detect regulation. Statistical analysis was performed using repeated-measures ANOVA, with significance set at p<0.05. The acupuncture group (A) exhibited energy regulation (20.8%), and only the PA group did not show pain reduction (p=0.077). The PL group experienced a decrease in energy (p=0.012). Notably, the SP (p=0.008) and BL (p=0.032) meridians showed balanced energy in the A group. Although laser acupuncture did not result in overall energy regulation, it was effective in reducing TMD-related pain. These findings suggest that while laser acupuncture may not balance energy levels, it holds potential as a pre-treatment strategy for pain management in TMD patients.
Antimicrobial Photodynamic Therapy in the Post-Operative Extraction of Lower Third Molars: A Randomized and Blinded Clinical Trial
Objective: This study aimed to evaluate local antimicrobial reduction protocols in post operative inflammatory-infectious events of lower third molar extractions. Methods It was a clinical, crossover, randomized and blind study with a sample of 22 patients (36 teeth). The patients underwent two surgical moments at intervals. The allocation of teeth was in 3 experimental groups: Group 1: Antimicrobial photodynamic therapy (aPDT); Group 2: 0.12% Chlorhexidine (CLX); Group 3: Control - 0.9% Saline Solution (SS 0.9%). The groups received treatment immediately after tooth extraction, and the evaluated parameters were: pain, edema, maximum mouth opening, and infection. Results: The data showed a statistically significant difference with aPDT therapy in edema, intragroup evaluation, and the distance between the gonial-tragus points (p = 0.022). In measuring mouth opening, there was a statistical difference in the intragroup assessment of aPDT and CLX (aPDT with p = 0.035, CLX with p = 0.038). There was a statistical difference in the presence of postoperative infection, with the aPDT and CLX groups showing the lowest values (p = 0.039). Regarding the pain, there was a decrease in the analysis on the 7th day of the aPDT group (P = 0.007). Conclusion: In conclusion, treatment with aPDT favors a statistically significant reduction of infection, edema, pain, and trismus in the postoperative period of third molar extractions.

Prevalence and Incidence of Hyperdontia in Radiographic Examinations from a Dental Clinic in Feira de Santana, Bahia – Brazil
Objective: To identify demographic data and the prevalence of hyperdontia through radiographic examinations. Materials and Methods: Radiographs from a database of a private clinic in Feira de Santana, Bahia, were analyzed. The database contained radiographs from the year 2018. The analysis method involved group observation and discussion, followed by classification based on radiographic parameters. Data were tabulated in Excel, including information on sex, age, and location. Results: A total of 3,657 radiographs were analyzed, of which 24 presented hyperdontia. Among the identified cases, 58.6% corresponded to male patients aged between 15 and 34 years. The morphological characteristics of the anomalies varied between supplemental (38.5%) and rudimentary (61.5%). Based on location, the supernumerary teeth were classified as mesiodens (3.8%), distomolars (57.7%), and paramolars (38.5%). According to the literature, the prevalence of supernumerary teeth is low, which is consistent with the findings obtained. Although the anterior region is frequently highlighted in the literature, this study demonstrated a higher prevalence in the posterior region. Conclusion: It is essential for dental surgeons to be aware of potential dental anomalies and the standard anatomy of each dental structure to ensure accurate diagnosis and appropriate treatment planning. Radiographic imaging plays a fundamental role in this process. Keywords: dental anomalies, panoramic radiography, prevalence.
Identification of quantitative dental anomalies in panoramic radiographs: a cross-sectional study
Objective: To identify the prevalence and characteristics of numerical dental anomalies through panoramic radiographic examinations. Materials and Methods: This is a cross-sectional study conducted using a database from a dental radiology clinic in Feira de Santana, Northeast Brazil, with radiographs from the period between 2019 and 2021. Data were tabulated in Excel, including information on quantity, gender, age, location, and year of the radiographs. Statistical analyses were performed using R software version 4.2.3 and the RStudio IDE. Results: The majority of patients were female (53%), and the group had a median age of 14.8 years. The location of the anomalies in the oral cavity varied among patients, with 41% in the mandible, 34% in the maxilla, and 24% in both arches. The results revealed a statistically significant association between age and the type of dental anomaly studied, which was not observed in relation to gender or location. Conclusion: This research stems from the need to understand the prevalence of these anomalies, thereby contributing to the advancement of scientific knowledge and the development of more effective strategies for prevention, diagnosis, and treatment. Keywords: dental anomalies, panoramic X-ray, prevalence.
Systemic use of analgesics and anti-inflammatories in dentistry: an integrative review of the literature
Introduction: Orofacial pain can be classified into different types, such as postoperative pain and pain associated with inflammation of the pulp and periapical tissues. Analgesics and anti-inflammatories play an essential role in the treatment of orofacial pain, providing symptomatic relief and reducing inflammation. Objective: Identify the most commonly used systemic analgesics and anti-inflammatories in dental practice. Method: This is an integrative review. The articles were selected in January 2025, based on searches in four databases (PubMed, Scopus, Embase and Web of Science), with publication dates in the last five years. After identifying the studies, 19 studies were included. Literature Review: This review identified nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, diclofenac, and aceclofenac, as the most commonly prescribed medications by dentists, along with antipyretic analgesics, mainly paracetamol. In cases of severe or refractory pain, the most commonly prescribed opioids were codeine, hydrocodone, and oxycodone, often administered in combination with paracetamol. Conclusion: NSAIDs and paracetamol were widely prescribed due to their efficacy in controlling pain and inflammation in different dental settings, such as the management of postoperative pain in oral and maxillofacial surgery, the treatment of pulpal and endodontic pain, and the control of inflammatory and infectious conditions.
Analysis of therapeutic efficacy in facial asymmetry resulting from condylar hyperplasia: a literature review
Introduction: Facial deformities affect various structures of the cranial skeleton and have multiple etiologies. One of the main factors causing this facial imbalance is unilateral condylar hyperplasia, which involves abnormal growth in the condylar head region. Objective: To synthesize the data available in the literature regarding condylar hyperplasia and its asymmetry, as well as to identify the best therapeutic options for the treatment of condylar hyperplasia in the present day. Literature Review: The mandibular condyle stands out among the mandibular regions with the greatest influence on asymmetry cases, presenting characteristics such as differences in facial morphology, malocclusion problems, laterognathism, bone dislocations, and temporomandibular joint pain. Condylectomy has been established as the gold-standard treatment for halting the growth of active condylar hyperplasia and reducing facial asymmetry. However, in the studies analyzed, a second intervention was often required through orthognathic surgery to further refine facial harmony, symmetry, and the occlusal plane. In cases of inactive condylar hyperplasia, treatment involving only orthognathic surgery proved to be the best approach. Conclusion: Condylectomy, combined with orthognathic surgery, had the lowest recurrence rate and the least need for additional intervention in cases of active condylar hyperplasia. In cases classified as inactive, orthognathic surgery alone proved to be the best approach. The treatments were effective in reducing facial asymmetry, malocclusions, and patients’ symptomatic complaints, making them recommended options for managing this condition.
Maxillary tuberosity versus palate as donor sites for connective tissue grafts: an integrative review of clinical trials
Objective: To review the literature comparing the maxillary tuberosity and the palate as donor sites for connective tissue grafts, focusing on the impact of graft origin on tissue volume gain. Literature Review: After applying the eligibility criteria, three articles were included. The mean tissue gain was greater for the maxillary tuberosity group in all studies, with a statistically significant difference compared to individuals who received a connective tissue graft from the palate (p<0.026) in one of them. However, the risk of tissue hyperplasia over time was reported in patients who received grafts from the maxillary tuberosity. Final Considerations: All included studies demonstrated greater tissue volume gain with connective tissue grafts from the maxillary tuberosity. However, based on this integrative review, it is not possible to conclude that this donor site is superior to the palate in this regard. It is suggested that donor site selection be individualized, considering tissue availability, patient needs, and technical expertise.
PHOTODYNAMIC THERAPY MEDIATED BY METHYLENE BLUE AGAINST ENTEROCOCCUS FAECALIS: A REVIEW OF THE LAST 20 YEARS OF PROTOCOLS AND ADVANCES
Introduction: Photodynamic therapy (PDT) mediated by methylene blue (MB) has been investigated as a promising approach to combat Enterococcus faecalis, a resistant pathogen often associated with persistent endodontic infections. Objective: To conduct a detailed review of the protocols used in methylene blue-mediated photodynamic therapy against E. faecalis over the last 20 years, highlighting the main strategies, operational parameters, and results obtained. Method: An integrative literature review was conducted, with searches in the MEDLINE database (via PubMed), selecting studies that addressed MB concentrations, light sources, irradiation times, and combinations with adjuvants against E. faecalis. Results: The results demonstrated that the efficacy of PDT depends on factors such as MB concentration, energy dose, and combination with adjuvants, such as potassium iodide (KI) and hydrogen peroxide (H₂O₂). Protocols using MB at concentrations between 0.001% and 0.01%, red light in the range of 660–670 nm, and fluence of 30–60 J/cm² proved to be particularly effective. Conclusion: MB-mediated PDT is a viable strategy for controlling E. faecalis, especially in cases of resistance to conventional treatments, but the standardization of protocols and the conduct of clinical trials are necessary to consolidate its clinical application. Keywords: Photodynamic Therapy. Methylene Blue. Enterococcus faecalis. Endodontics.
Importância da Localização do Quarto Canal (MV2) no Tratamento Endodôntico de Primeiro Molar Superior: relato de caso
The maxillary first molar has the highest failure rates in endodontic treatment due to the high prevalence of a fourth canal, the mesiobuccal 2 (MB2) canal. Failure to locate or properly treat this canal often results in treatment failure. Objective: To report a case of endodontic treatment in a maxillary first molar with MB2 and highlight the importance of identifying and treating the fourth canal, along with discussing potential anatomical variations. Case Report: A 37-year-old female patient presented at the Dental Clinic of the Postgraduate Course in Endodontics at IOA – Chapecó/SC, referred by the Esthetics Course, with complaints of severe pain in a left maxillary tooth. After anamnesis, clinical and radiographic evaluation, and sensitivity tests, a diagnosis was established, indicating endodontic treatment of the maxillary first molar (tooth #26). The treatment was completed in three sessions. In the first session, the main canals were prepared, and the MB2 canal was located. Subsequent sessions focused on further preparation and the complete obturation of the root canal system. Final Considerations: Dentists performing endodontic treatments must thoroughly understand root canal anatomy and its variations. Staying updated on current technologies that assist in planning and executing treatments is crucial for achieving favorable prognoses and high success rates. Proper localization of canals during the initial treatment minimizes the need for retreatments, thus enhancing the overall success of endodontic therapy.
Clinicopathological aspects, diagnosis, and treatment of mucoepidermoid carcinoma
Introduction: Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland neoplasm, with histological and biological heterogeneity. It can arise in any salivary gland and affects patients of various ages. Although it shows a good response to early treatment, its molecular biology and prognostic factors are still under study. Objective: This study aims to provide a comprehensive analysis of the clinicopathological aspects, diagnosis, and treatment of mucoepidermoid carcinoma. Materials and Methods: A search was conducted for scientific articles in the Scientific Electronic Library Online (SciELO), US National Library of Medicine (PubMed), and ScienceDirect databases. Studies published between 2014 and 2024 were analyzed. The selection included English-language articles using the keywords "mucoepidermoid carcinoma", "mucoepidermoid carcinoma salivary glands," and "MEC tumor salivary glands". Conclusion: Mucoepidermoid carcinoma shows great clinical and prognostic variability. In general, low-grade cases have an indolent behavior, while high-grade forms can be aggressive, with a risk of metastases and recurrence. Diagnosis is made through clinical evaluation, imaging, histopathology, and immunohistochemistry. Treatment is mainly surgical, with the possibility of lymphadenectomy and radiotherapy in higher-risk cases.

Modification of titanium surfaces by cathodic polarization: a promising technique for enhancing osseointegration
Titanium implants represent successful alternatives for bone and dental replacement in healthy patients. Modifications on the surface can increase their bioactivity and bone regeneration, with a consequent impact on the implant survival rate, and the modification technique used can impact the cellular response. The aim of this study was to characterized titanium surfaces modified by the cathodic polarization method with different current densities and exposure times. Seventy-two blocks of pretreated pure titanium were used and randomly allocated in four experimental groups, being 18 samples for group. The cathodic polarization process was conducted in a solution of acetic acid and sodium acetate (pH 3), being the titanium specimens used as cathode and a rectangular platinum as anode at a controlled temperature of 22°C. The current densities were 1.6 mA/cm2 and 4.5 mA/cm2 and the exposure times were 2h and 4h. Samples were dried and maintained in a Nitrogen vacuum chamber. The modified titanium samples were topographically characterized using Atomic Force Microscopy (AFM), Scanning Electron Microscopy (SEM) and Energy Dispersion X-Ray Spectroscopy (EDX). Water contact angles formed in the surface of the titanium were measured with a tensiometer (ThetaLite TL101; Biolin Scientific Inc., Finland) using the sessile drop method, in four different times in minutes: t=0, t=15, t=30 and t=45. The contact angle formed between the water droplet and the surface was monitored in real time for 60 seconds. AFM and SEM analysis showed rougher surfaces in the modified groups. EDX data revealed the presence of sodium, carbon, and titanium mainly. The Wettability test indicated that all groups showed contact angles with less than 90°. The Control Group and Group 3 showed higher contact angles, around 76° to 71° and Groups 1 and 2 lower contact angles, around 66° to 63° respectively. The topography analysis showed higher roughness in the groups with higher current density and exposure time. The electrochemical cathodic polarization technique modified the titanium surfaces, as current density and exposure time influenced the roughness and wettability of the treated titanium surface, properties that could enhance osseointegration.
Knowledge and confidence in the prescription of anti-inflammatory drugs among dentistry students: a cross-sectional analysis
Objective: To evaluate the knowledge of Dentistry students at the State University of Feira de Santana (UEFS) regarding the pharmacotherapy of anti-inflammatory drugs, addressing pharmacodynamics, pharmacological classes, adverse reactions, and clinical indications, as well as exploring perceptions about teaching and learning in the area. Materials and Methods: An online self-administered questionnaire, containing 11 multiple-choice questions and 1 open-ended question, was applied to 180 students. The participants were grouped into intermediate semesters (IS; 5th to 7th) and final semesters (FS; 8th to 10th). The data were analyzed using descriptive and inferential statistical tests, with a significance level of 5%. Results: 46.1% of eligible students responded to the questionnaire. The overall average score was 5.76 out of 10, with no differences between the IS group (5.85) and the FS group (5.68; p = 0.237). Significant differences were observed in therapeutic approaches to oral pathologies: for recurrent aphthous stomatitis, the FS group performed better (p = 0.033; OR = 3.2), while for erosive lichen planus, the IS group had better results (p = 0.029; OR = 2.7). Additionally, there was a predominance of incorrect answers related to the adverse effects of anti-inflammatory drugs, with similar performance between the IS and FS groups (p>0.05). In self-perception, 49% of the IS group classified their knowledge as "insufficient," while 60% of the FS group considered it "sufficient." Conclusion: Although students demonstrated average general knowledge about anti-inflammatory drugs, the gaps in practical and advanced topics, especially related to adverse reactions and the management of patients with comorbidities, highlight the need to more effectively integrate theoretical and practical content in pharmacotherapy education. Keywords: Anti-inflammatory drugs; Dentistry students; Pharmacotherapy
CAPACITY OF MONOCHROMATIC COMPOSITE RESINS TO PLAY A MIMETIC ROLE FOR SUBSTRATES WITH DIFFERENT SHADES
This study aimed to evaluate the mimicry potential of four monochromatic composite resins: Vittra APS Unique; Charisma Diamond One; Aura Bulk Fill and Palfique Omnichroma. Resins were tested on different substrate colors (A1, A2 and A3) and depths (1, 2 and 4 mm). The color was measured with a spectrophotometer and the ΔE calculated by the CIEDE 2000 system, as well as the color correspondence with the Vita Classical and 3D Master scales. The difference in color between the samples was verified using the two-way ANOVA test (resin and cavity depth), adopting a significance level of 5%. The Aura Bulk Fill resin statistically showed the lowest color variation in all groups, except for the A1 4mm group, in which the Charisma Diamond One and Palfique Omnichorma resins showed similar values. Meanwhile, the Vittra APS Unique resin statistically showed the greatest color variation in all groups, except for the A2 2mm group, in which it showed similar values to the Palfique Omnichroma resin. The evaluated composite resins better mimic lighter substrates and in shallower cavities. In a comparative analysis between the different commercial brands studied, it can be considered that the Aura Bulk Fill composite resin presented results significantly superior to the other materials, while the Vittra APS Unique presented statistically inferior results and the Charisma Diamond One and Palfique Omnichroma resins presented results similar to each other.

Avaliação de diferentes métodos de tratamento superficial para reparo de resina composta
O reparo das restaurações de resina composta diminui o desgaste de estrutura dentária e aumenta consideravelmente a longevidade destas restaurações. O objetivo do presente estudo in vitro é avaliar a morfologia da superfície de resina composta a ser reparada após diferentes técnicas de preparo. Foram confeccionadas 14 amostras de resina composta divididas em 7 grupos (n=2) e envelhecidas através do processo de termociclagem (220 ciclos). Então, no grupo controle negativo os espécimes não receberam nenhum tratamento enquanto nos grupos experimentais os corpos de prova receberam os seguintes tratamentos de superfície: jateamento com óxido de alumínio + ácido fosfórico 37%; ácido fluorídrico 5%; ácido fosfórico 37%; ponta diamantada (granulação normal) + ácido fosfórico 37%; ponta diamantada (granulação fina) + ácido fosfórico 37%; ponta diamantada (granulação extrafina) + ácido fosfórico 37%. Para análise das superfícies tratadas, as amostras foram preparadas e avaliadas em microscopia eletrônica de varredura (MEV). Foi realizada uma análise descritiva das superfícies observadas. No grupo controle negativo não foi observada nenhuma rugosidade superficial, assim como nos grupos que receberam tratamento químico com ácido fosfórico e ácido fluorídrico, enquanto nos grupos que receberam tratamentos mecânicos foi possível observar rugosidades superficiais compatíveis com a granulação da ponta diamantada, enquanto o jateamento de óxido de alumínio promoveu irregularidades uniformes por toda a superfície da amostra. Pode-se concluir que os tratamentos mecânicos promoveram irregularidades da superfície da resina composta, sendo que as pontas diamantadas finas e extrafinas, assim como o jateamento com óxido de alumínio promoveram retenções mais uniformes.
Microbiological tests on toothbrushes: disinfection and storage methods
Toothbrushes, despite being simple and widely used tools, can also pose a risk of disease transmission. To minimize this risk, it is essential to adopt effective methods of toothbrush storage and disinfection. This study aimed to evaluate the available disinfection methods for toothbrushes and identify the safest storage practices. Method: This research is quantitative, cross-sectional, exploratory and prospective. Eight adult toothbrushes were analyzed, which were contaminated and stored in different ways and disinfected with different agents. The contamination assessment was performed by seeding in culture media (Brain Heart Infusion - BHI, Blood Agar, Sabouraud Agar, Baird Parker Agar and Eosin Methylene Blue - EMB), with subsequent analysis of the turbidity of the BHI vials using a spectrophotometer. Results: From the microbiological analysis, two results were obtained. The first was related to the storage media, which, according to the spectrophotometer, showed that the toothbrushes stored in bags and cases presented a higher degree of turbidity, which indicates a higher bacterial concentration and greater contamination, while the toothbrushes stored with a lid in a closed environment obtained the best results with less contamination and consequent turbidity of the medium. All plates showed bacterial and/or fungal growth. The second result is related to disinfection, which, according to the spectrophotometer, seemed to be more effective with 0.12% chlorhexidine, by means of friction. Conclusion: The best practice for storing toothbrushes seems to be the use of protective lids in closed environments, such as drawers or cabinets. Among the disinfectant agents evaluated, 0.12% chlorhexidine demonstrated the greatest effectiveness in reducing bacterial contamination.
Estudo histomorfológico de um grupo de lesões periféricas de células gigantes
Peripheral giant cell lesion (PGCL) is considered a non-neoplastic proliferative process with significant prevalence in oral cavity. The objective of this research was to qualitatively and quantitatively evaluate histomorphological characteristics of a PGCL group, correlating them with the patients&#39; clinical and sociodemographic findings. For morphological (histopathological) study, the histological sections of the selected cases were evaluated. Multinucleated giant cells were classified as type 1 or 2 and the quantification of cells exhibiting evidence of phagocytosis was evaluated in 5 consecutive high power fields (400x) for each PGCL case. In a higher 14 RFO UPF, Passo Fundo, v. 30, n. 1, 2025 magnification field, the nuclei of multinucleated giant cells were counted, and an average was established for each case. Areas of hemorrhagic extravasation and foci of hemosiderin deposition were evaluated and recorded qualitatively. The results revealed that sociodemographic characteristics, such as age, sex and race, did not demonstrate statistically significant associations with the histopathological aspects of PGCL. However, we observed significant correlations between clinical findings of the lesions, such as appearance and growth speed, with histopathological characteristics, such as the number of giant cells and the type of giant cells. Evidence of phagocytosis, especially in type 1 giant cells, hemosiderin pigmentation and areas of hemorrhagic extravasation were identified in most of the sample. The results suggest that the appearance and growth of PGCL in the present study may be related to specific microscopic features.

Ozone as a remineralizing agent in the treatment of caries lesions: a literature review
Introduction: Dental caries is one of the most prevalent diseases in the world, and the possibilities for its treatment are constantly being studied and evolving. Ozone has been presented as a promising possibility for treating caries lesions due to its ability to remineralize dental tissue. However, it is necessary to further investigate the effectiveness of this technique for its clinical use. Objective: to carry out a review of scientific literature in order to analyze, compile and present data related to ozone as a remineralizing agent in the treatment of caries lesions. Method: the search for materials was conducted in the PubMed, Bireme and SciELO databases, including articles published from 2011 to 2024, in Portuguese and English. The initial search resulted in 89 articles. Of these, 77 were excluded because they did not meet the established inclusion criteria. In total, 12 articles were selected for detailed analysis. Literature review: the research analyzed showed divergences in relation to the results obtained: some studies identified the remineralizing action of ozone, either alone or in combination with other agents and treatments, while other studies indicated that ozone had lower efficacy compared to others remineralizing agents. Conclusion It is possible to highlight that ozone has potential as a remineralizing agent in the treatment of caries lesions, and can serve as an alternative to conventional techniques. However, more studies are needed to ensure its effectiveness. Keywords: ozone; ozone therapy; tooth decay; dental remineralization; dentistry.

Analysis of satisfaction of dental surgeons bounded with the basic health units from the north of Paraná
The unified public health system (SUS) is a social process that holds permanent construction, being the continuous discussion about its model of care is of highest importance. Therefore, the present study aims to analyze the degree of satisfaction of dental surgeons bound to the Basic Health Units located in the North of Paraná state. It was carried out in an exploratory quantitative-qualitative approach, in which the data collection happened through an online semi-structured questionnaire, containing dissertations and multiple choice questions. Therefore, 24 dental surgeons were interviewed, mostly women (83.3%), between 20 and 40 years old (66,6%), which work as a general practitioner (45.8%). In terms of the insights of the SUS, 79.2% were satisfied with their work, but showed an intermediate satisfaction when compared with their wage (70.8%) and the infrastructure that the SUS offers related to their daily routine. Thereby, it is concluded that most participants rate their work in the public healthcare system as satisfactory, but their perceptions, according to the wage, appreciation, work team and workload resulting in a negative influence on their activities, requiring a deeper analysis of the working conditions of these professionals
“PET-SAÚDE” Interprofessionality in extension:
The aim was to report the student experience and the results of an extension project carried out remotely during the COVID-19 pandemic in the city of Governador Valadares, MG by students and teachers of the Dentistry and Physiotherapy course of the Federal University of Juiz de Fora. The target audience were adult users of social networks. Health promotion actions were carried out through the social networks Instagram, Facebook and Youtube, with the construction of informative educational material based on accessible scientific evidence and objectives, elaborated using diverse strategies, in order to replace the individual as the author of his health. The health issues addressed included the most prevalent health problems in the population, self-care and general health with a special focus on COVID-19. The material was posted weekly in the format of posts, videos, Reels, etc. The accesses, likes and participation were analyzed, being observed high involvement of internet users. The actions developed in the project further strengthen the formation of the student as an active agent in the promotion and prevention of health problems. The use of social networks was a tool for dissemination and access to relevant health information, promoting the development of skills necessary for professional training.
Use of stem cells from deciduous teeth in bone regeneration for the treatment of cleft lip and palate: A review of in vivo studies
Objective: This study aimed to review in vivo studies on the use of stem cells derived from exfoliated deciduous teeth (SHED) for bone regeneration, particularly in the treatment of cleft lip and/or palate (CL/P).Methodology: The review followed PRISMA guidelines and included studies from PubMed, Scopus, and Google Scholar databases, published in the last 10 years in English, Spanish, or Portuguese. Strict inclusion and exclusion criteria were applied, focusing on in vivo studies using SHED for CL/P treatment. Keywords such as “Bone Regeneration,” “Tissue Engineering,” and “SHED” were used for the search. After screening 1,045 records and excluding duplicates, 7 studies were selected for full review.Results: The review identified 7 relevant studies, 6 of which were in vivo animal studies, and 1 was a clinical case report. These studies demonstrated that SHEDs effectively promoted bone regeneration, presenting a less invasive and promising alternative to traditional bone grafting techniques.Conclusion: SHEDs show significant potential in bone regeneration, offering a less invasive treatment option with fewer complications compared to autogenous bone grafts. However, more research is needed to address long-term safety, tumorigenesis, and optimal clinical applications before widespread clinical adoption.

Introduction: Knowing the oral health situation of visually impaired people is necessary to develop actions for the control and treatment of oral diseases. Objective: to identify the oral health situation of patients with visual impairment registered in ESF units linked to the Catholic University of Pelotas-RS. Methods: A cross-sectional observational study was carried out with a final sample of 26 adult patients. Data were collected through a questionnaire on oral hygiene practices, difficulties in oral health care and access to information and dental services, followed by a clinical examination using DMFT and IPC indices. The data were tabulated in the Microsoft Excel® program and detailed descriptively. Results: The majority of visually impaired people were female (53.85%) with an average age of 65.15 years. The average DMFT was 22.38 and in the survey of periodontal conditions, 73.72% of sextants were excluded and 23.72% showed changes. Regarding oral hygiene practices, 100% of participants performed their hygiene alone and only 23.08% ex posted some difficulty. Regarding access to dental services, 76.92% reported having accessibility problems and 61.54% said there was no dentist at the UBS. Conclusion: They present positive oral hygiene practices, unsatisfactory clinical conditions with a high DMFT index, a large number of sextants excluded due to tooth loss and lack of access to dental services.
Factors associated with self-perception of oral health in nonagenarian long-lived elderly: a longitudinal study from the AMPAL
Identify which factors are associated with self-perception of oral health in long-lived nonagenarians. Analytical cross-sectional study with nonagenarian participants (≥90 years old) of the longitudinal monitoring project entitled “Atenção Multiprofissional ao Longevo – AMPAL” in the city of Porto Alegre, Rio Grande do Sul – Brazil. Sociodemographic aspects, clinical characteristics, nutritional status and self-perception of oral health (PHC) were the variables investigated. Descriptive analysis, Pearson correlation and multiple linear regression were performed (p<0.05). Participated 234 long-lived people, of whom the average age was 92.35±3.62 with good oral APS and 92.23±3.66 with poor oral health. In the final model, schooling, each year of study represented an 8% lower chance of having poor Oral APS (p=0.063). According to the GDS, long-lived individuals with normal exams had a 50% lower chance of having poor Oral PHA when compared to long-lived individuals with altered exams (p=0.088). Long-lived individuals with xerostomia had an 83% higher chance of having poor Oral PHA. The chewing classification was the variable with the greatest influence, with long-lived individuals with poor classification having significantly more chances of having poor Oral PHA (p<0.001). According to the body mass index, overweight long-lived individuals had a 15% lower chance of having poor Oral PHA than underweight long-lived individuals (p=0.0270). The majority of nonagenarians had good Oral PHA, with women reporting poorer Oral PHA. It was found that those who reported xerostomia, low weight and difficulty chewing were more likely to have poor oral self-perception.
