The use of a variety of bleaching techniques has attracted much interest from the profession, as they are non-invasive and relatively simple to carry out. Coupled with the uncertain legal situation within the European community, and especially within the UK, this series of articles hopes to give a broad overview of bleaching techniques, their efficacy and relative safety, as well as update the ...

INTRODUCTION Common clinical experience suggests that tooth whitening agents are 100% effective. This study uses meta-analysis of data from published randomized controlled clinical trials to determine the efficacy of tooth whitening agents. METHODS A MEDLINE search strategy was developed and implemented to systematically identify clinical trials on dentist-prescribed, home-applied tooth white...

STATEMENT OF PROBLEM The use of tooth bleaching agents has been very popular treatment in dentistry. The bleaching agents have an inherent potential to impair surface properties of existing composite resin restorations. PURPOSE This study evaluated the effect of a combined bleaching regimen on the surface microhardness of a Silorane-based and a sealed methacrylate-based composite. MATERIALS...

There are concerns that tooth bleaching agents may adversely affect dental materials. The aim of this study was to test the hypothesis that increasing concentrations of hydrogen peroxide (HP) are more effective than water at increasing metal ion release from two typical dental casting alloys during bleaching. Discs (n = 28 for each alloy) were prepared by casting and heat treated to simulate a ...

The objective of this review article is to abridge all the available information regarding the Mechanism of tooth bleaching and their consequences on dental soft and hard tissues structures ,physical properties morphology and color of composite restorations. The controversial reviews regarding the effects of dental bleaching agents were reviewed. Information from the original scientific full pa...

BACKGROUND Coral bleaching events vary in severity, however, to date, the hierarchy of susceptibility to bleaching among coral taxa has been consistent over a broad geographic range and among bleaching episodes. Here we examine the extent of spatial and temporal variation in thermal tolerance among scleractinian coral taxa and between locations during the 2010 thermally induced, large-scale ble...

INTRODUCTION Esthetics is one of the common issues because of which patients consult dental orthodontic treatment. Two ways of tooth bleaching are available these days, which includes in-office bleach and home bleach. Various bleaching protocols are available these days for treating the tooth surfaces. Hence, we planned the present study for investigating the impact of various intracoronal blea...

BACKGROUND Globally, coral bleaching has been responsible for a significant decline in both coral cover and diversity over the past two decades. During the summer of 2010-11, anomalous large-scale ocean warming induced unprecedented levels of coral bleaching accompanied by substantial storminess across more than 12° of latitude and 1200 kilometers of coastline in Western Australia (WA). METHO...

UNLABELLED There is no consensus about the waiting time necessary for the patient to start consuming beverages containing colorants again after bleaching. OBJECTIVE To evaluate the influence of beverages with coloring agents on bleached bovine incisors considering the time elapsed after bleaching. MATERIALS AND METHODS Sixty bovine incisors were bleached with 35% hydrogen peroxide for in-of...
