Abstract

Background: Although no clinically remarkable damages because of vital bleaching of dental hard tissues has been described in literature, there are scientific reports demonstrated alterations of the histological aspects and composition of bleached dental enamel. It is observed that bleaching with 10% carbamide peroxide may result in a decrease of the calcium, phosphate and also of the fluoride amount in enamel. It was shown that demineralization of bleached enamel could be balanced by a remineralization period following the bleaching period. Purpose: To evaluate the effect of different remineralizing agents on stains absorption and surface roughness of freshly bleached teeth. Design: An in-vitro study. Methods: A total of 72 intact sound freshly extracted human upper anterior teeth was collected, scaled, polished and stored in distilled water and divided into 4 equal groups (18 each) according to the enamel surface treatment applied immediately after bleaching measurements; group A was received no surface treatment and served as a control group. In group B: the enamel surface was treated by fluoride varnish, while group C enamel surface was treated by CPP-ACP without fluoride & group D by CPP-ACP with fluoride. Results: The study showed that group A is affected by the most significant color change after 2 and 4 weeks with staining, followed by group C and group B, while group D showed the least color change after the same periods. Group A showed the highest significant surface roughness values after 2 and 4 weeks with staining, followed by group B and group C, while group D showed the least surface roughness values after the same periods. Conclusion: Remineralizing agents have a significant effect on decreasing stain absorption and surface roughness of freshly bleached enamel.
