Objective: to perform an epidemiological survey of salivary gland diseases by analyzing medical records from a Stomatology Service in southern Brazil. Methods: the sample consisted of approximately 24,000 medical records of patients assisted at the Stomatology Service of the São Lucas Hospital between 1977 and 2017. The following salivary gland disorders were selected: mucocele, ranula, sialolithiasis, infectious sialadenitis, Sjögren’s syndrome, necrotizing sialometaplasia, and benign or malignant neoplasms. The data collected were analyzed by descriptive and inferential statistics using the chi-squared test. Results: from the 817 disorders found, 56.2% were mucocele, 11.1% sialadenitis, 10.3% ranula, 10.1% sialolithiasis, 5.5% benign neoplasms, 4.3% Sjögren’s syndrome, 2.1% malignant neoplasms, and 0.4% necrotizing sialometaplasia. Mucocele was more prevalent in men, while ranula and Sjögren’s syndrome were more associated with women. The other diseases did not present gender preference. The location of the lesions, clinical characteristics, and age of the patients affected were also assessed. Conclusion: salivary gland diseases deserve special attention among stomatognathic system disorders due to the complex anatomy of such structures, the importance of saliva in the oral homeostasis, and the indolent clinical behavior of the malignant neoplasms affecting these glands.
