Objective: Evaluate the cariogenic potential of hard and soft candies and their demineralizing potential in bovine enamel after erosive cycle. Methods: Hard candies (HC) from different brands were selected: Tic-Tac®, Halls® and IceKiss® and the soft candies (SC): Lílith®, Azedinha®, Mentos Rainbow®, and Dori Gomets®. For the physical-chemical analysis, the candies were dissolved in distilled water (1:10) and the pH, the titratable acidity (ATT), and the presence of total soluble solids (SST/°Brix) were determined. In the erosive test, 40 bovine enamel specimens were divided into four groups (n=10): GCN: artificial saliva; GCP: hydrochloric acid, GT1: Lílith® green apple candy solution; GT2: IceKiss® extra strong candy solution. The acid challenge was performed for 2 minutes, 4x per day, with 2 hours of immersion in artificial saliva for five days. Results: pH values for HC ranged from 2.88 to 5.53 and for SC ranged from 2.73 to 4.16. ATT at pH 5.5 varied from 0.07 mL to 39.40 mL of NaOH 0.1 N for HC and 1.53 mL to 35.83 mL for SC. ATT at pH 7,0 varied from 0.2 mL to 49.13 mL of 0.1 N NaOH for HC and from 2.37 mL to 49.97 mL for SC. The content of SST of all HC was higher than 8.5 °Brix and for SC, varied between 5.3 to 8.83 °Brix. The GCP group showed greater demineralization than GCN and GT2 (p<0.05). Conclusion: Most HC and SC dissolved in distilled water were potentially erosive and cariogenic.
