Aim This review article will help clinicians improve their understanding of the history of
bleaching procedures, bleaching types, components, mechanisms, and their effects on soft …

Tooth discoloration varies in etiology, appearance, localization, severity, and adhesion to
tooth structure. It can be defined as being extrinsic or intrinsic on the basis of localization …

Objective: Internal and external bleaching procedures utilizing 3–35% hydrogen peroxide
solutions or hydrogen peroxide releasing agents, such as carbamide peroxide or sodium …

The aim of this study was to evaluate the surface roughness, microhardness and
morphology of human enamel exposed to six bleaching agents (at baseline and post …

Oxygen inhibits polymerization of resin-based materials. We hypothesized that
compromised bonding to bleached enamel can be reversed with sodium ascorbate, an anti …

A bstract Tooth whitening products may be in contact with intraoral structures for several
hours or they may be used daily to whiten the teeth. Consequently, these products should …

Objectives. To review the various methods and techniques available to assess enamel
erosion in vitro. Data. Peer reviewed scientific articles. Sources. Medline and Web of …

summary The purpose of this study was to comparatively investigate the effect of antioxidant
treatment and delayed bonding after bleaching with three different concentrations of …

The acid-etch-technique has provided an ideal surface for bonding to enamel by using 30-
40% phosphoric acid. The resulting etch pattern is characterized by the profuse formation of …

Objectives. The aim of this study was to evaluate the effects of low concentrations of
carbamide peroxide bleaching agents (CP) on the ultimate tensile strength of enamel (UTS) …
