1. Avaliação através da tomografia por coerência óptica do esmalte dentário após o uso de dentifrícios clareadores
Resumo Introdução Historicamente, materiais abrasivos, como mármore em pó, corais e cinzas ósseas, eram utilizados para higienização dentária. Com a evolução, tais materiais foram substituídos por dentifrícios aplicados em escovas dentais, com a mesma finalidade. Objetivo Avaliar, através da Tomografia por Coerência Óptica, o desgaste do esm

2. Whitening toothpaste containing activated charcoal, blue covarine, hydrogen peroxide or microbeads: which one is the most effective?
Abstract The efficacy of whitening toothpastes is questionable and controversial. Clinicians, patients and researchers have expressed concern with whitening toothpastes due to the risk of wearing the dental structure and the potential for disappointment if the advertised cosmetic results are not achieved. Objective: This study compared the whitening performa

3. Does a toothpaste containing blue covarine have any effect on bleached teeth? An in vitro, randomized and blinded study
Abstract The objective of this study was to analyze the effect of bleaching toothpastes, both conventional and those containing the new whitening agent Blue Covarine, on teeth previously bleached by conventional techniques (in-office and at-home). Squared bovine enamel/dentin blocks (6.0 x 6.0 x 2.0 mm) were randomly distributed in 6 groups (n = 15), accordi

4. Can a bleaching toothpaste containing Blue Covarine demonstrate the same bleaching as conventional techniques? An in vitro, randomized and blinded study
ABSTRACT Objective The purpose of this in vitro study was to compare the efficacy of a bleaching toothpaste containing Blue Covarine vs. conventional tooth bleaching techniques using peroxides (both in-office and at-home). Material and Methods Samples were randomly distributed into five experimental groups (n=15): C - Control; BC – Bleaching toothpaste

5. AvaliaÃÃo in vitro do efeito da escovaÃÃo com dentifrÃcios clareadores sobre a superfÃcie dentinÃria / In vitro evaluation of the toothbrushing effect with whitening toothpaste abrasion on root dentine
A escovaÃÃo tem um papel importante na etiologia da hipersensibilidade dentinÃria. AbrasÃo pode estar relacionada a abrasivos contidos nos dentifrÃcios. O objetivo deste estudo foi comparar por perfilometria mecÃnica o efeito da abrasÃo da escovaÃÃo com dentifrÃcios clareadores e convencionais na dentina radicular. Noventa espÃcimes de dentina (4

6. Effect of whitening toothpaste on titanium and titanium alloy surfaces
Dental implants have increased the use of titanium and titanium alloys in prosthetic applications. Whitening toothpastes with peroxides are available for patients with high aesthetic requirements, but the effect of whitening toothpastes on titanium surfaces is not yet known, although titanium is prone to fluoride ion attack. Thus, the aim of the present stud

7. Physical-chemical characteristics of whitening toothpaste and evaluation of its effects on enamel roughness
This in vitro study evaluated the physical-chemical characteristics of whitening toothpastes and their effect on bovine enamel after application of a bleaching agent (16% carbamide peroxide). Physical-chemical analysis was made considering mass loss by desiccation, ash content and pH of the toothpastes. Thirty bovine dental enamel fragments were prepared for

8. Color, composition and superficial roughness evaluation of bovine enamel after treatment with different gel and whitening dentifrice using reflectance, superficial roughness and μEDX / Avaliação da cor, superfície e composição do esmalte dental bovino após tratamento com diferentes géis e dentifrícios clareadores por meio de fotorreflectância, rugosidade superficial e EDEX
Aim: to investigated quantitatively the color alteration, superficial roughness and composition of the bovine enamel after dental bleaching with carbamide peroxide 10% and hydrogen peroxide 6%. Methods: It was used 90 fragments of bovine teeth that were randomized divided in 9 groups (n=10) dependents on the bleaching treatments (n=10): Hydrogen peroxide 6,0
