Effect of high- or low-concentration bleaching agents containing calcium and/or fluoride on enamel microhardness.
The aim of this in vitro study was to evaluate enamel microhardness following bleaching treatments using either high- or low-concentration hydrogen peroxide (HP) agents containing calcium and/or fluoride. Sixty enamel blocks were bleached with 1 of 6 different bleaching agents (n = 10). The high-concentration HP agents were Whiteness HP Maxx (35% HP), Whiteness HP Blue (35% HP, 2% calcium gluco...
متن کاملEffect of thickener agents on dental enamel microhardness submitted to at-home bleaching.
Dental bleaching occurs due to an oxidation reaction between the bleaching agents and the macromolecules of pigments in the teeth. This reaction is unspecific and the peroxides can also affect the dental matrix causing mineral loss. On the other hand, recent studies have suggested that the thickener agent carbopol can also cause mineral loss. Thus, the objective of this study was to evaluate in...
متن کاملInfluence of study design on the impact of bleaching agents on dental enamel microhardness: a review.
OBJECTIVE Numerous studies investigated the impact of bleaching procedures on enamel microhardness. The outcomes of these studies reveal inconsistencies regarding the fact whether a microhardness reduction due to bleaching occurs or not. Aim of the present review was to summarize the existing literature of external bleaching therapies, which used microhardness tests for evaluation of possible e...
متن کاملEffect of a carbamide peroxide bleaching gel containing calcium or fluoride on human enamel surface microhardness.
This in vitro study evaluated the surface microhardness of human enamel submitted to bleaching with 10% carbamide peroxide (CP) containing calcium or fluoride. Ninety-eight dental blocks (5 x 5 mm2) with polished enamel surfaces were randomly assigned to 7 treatment groups (n=14), as follows: without bleaching and storage in artificial saliva (control); 10% CP; 10% CP + 0.05% calcium; 10% CP + ...
متن کاملThe Effects of Tooth Bleaching Agents on Microhardness of Enamel in situ
The demand for conservative esthetic dentistry has dramatically grown and so has the rapid development of new non-restorative treatments for discolored teeth. Nightguard vital bleaching has become one of the most frequently used treatment modality for improving the esthetic appearance of teeth, primarily because of its relative ease of application, the safety of 10% carbamide peroxide bleaching...
