Abstract
Background: Tooth discoloration is common in society, and dental bleaching techniques are used to address this issue. A natural component from pineapple hump is being studied for its potential use in teeth-whitening treatments. Following dental whitening, teeth may become more uneven, and consuming acidic drinks can further increase roughness on the enamel surface. Objective: This study aims to assess the effects of acidic beverages on enamel roughness after tooth bleaching. Method: This was a laboratory experimental study using 40 maxillary central incisors. The bleaching procedure was performed using pineapple hump gel extract applied to the sample surface for a period of 6 h each day, for 14 days. After bleaching, basic enamel surface roughness measurements were taken using a profilometer, and the samples were immersed in different beverages (coffee, carbonated drinks, tea, and orange juice). After 14 days, the surface roughness of each sample was remeasured. Result: The results showed that different beverages significantly affected tooth enamel surface roughness after dental bleaching (p<0.05), with carbonated drinks (pH 2.7) and orange juice (pH 3.6) having the most pronounced impact. 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.
