Higher Fluorosis Severity Makes Enamel Less Resistant To Demineralization
In vitro evaluation of the microhardness of bovine enamel exposed to acid solutions after bleaching
(Sociedade Brasileira de Pesquisa Odontológica (SBPqO), 2011-11-01)
Acid erosion is a superficial loss of enamel caused by chemical processes that do not involve bacteria. Intrinsic and extrinsic factors, such as the presence of acid substances in the oral cavity, may cause a pH reduction, ...
Anterior restorations in bleached teeth: Difficulty establishing the color after bleaching
It is becoming more common for patients to look for cosmetic procedures in dental offices. The search for lost or desired esthetics by patients is increasingly frequent and the professional must be able to meet this demand. ...

Effects evaluation of remaining resin removal (three modes) on enamel surface after bracket debonding
Introduction: An appropriate selection of instruments is essential to perform a correct debonding technique, by properly removing orthodontic brackets and the remaining resin. Objective: The aim of this study was to evaluate ...
Effect of bleaching on sound enamel and with early artificial caries lesions using confocal laser microscopy
The aim of this study was to evaluate effect of bleaching agents on sound enamel (SE) and enamel with early artificial caries lesions (CL) using confocal laser scanning microscopy (CLSM). Eighty blocks (4 × 5 × 5 mm) of ...
Effect of antioxidant agents on bond strength of composite to bleached enamel with 38% hydrogen peroxide
(ABM, ABC, ABPol, 2011-01-01)
This study evaluated the effect of antioxidant agents on microtensile bond strengths (mTBS) of composite to bleached enamel. Fifteen freshly extracted human third molars were selected and randomly assigned to 6 groups (n ...
