ABSTRACT
Objectives: To evaluate the effects of acidic beverages on enamel roughness following tooth bleaching using pineapple hump extract. Methods: Forty maxillary central incisors were subjected to a bleaching protocol involving daily application of pineapple hump gel extract for 6 hours over 14 days Enamel surface roughness was measured using a profilometer before and after immersion in various beverages (coffee, carbonated drinks, tea, and orange juice) for another 14-day period. Results: A significant increase in surface roughness after exposure to the beverages (p<0.05), particularly with carbonated drinks (pH 2.7) and orange juice (pH 3.6). Conclusion: The study found that acidic beverages, such as carbonated drinks and orange juice, can increase the roughness of tooth enamel after teeth whitening with pineapple hump gel extract. These two drinks are more acidic than others, which might cause more mineral loss in the teeth and impair the surface roughness of the tooth enamel.
