Objective: The objective of this study was to characterize and correlate the absorption spectra of three photoinitiators [camphorquinone (CQ), diphenyl(2,4,6-trimethylbenzoyl) phosphine oxide (TPO) and phenylbis (2,4,6-trimethylbenzoyl)-phosphine oxide (BA...
ABSTRACT Introduction: Third generation of LED light curing units might be used in short exposure periods for orthodontic brackets bonding. Objective: This study evaluated the effect of the different radiant exposure (RE) values: Manufacturers' instructions (MI), ½ MI, 1/4 MI and Turbo mode. Two thir...
Introdução: a resina composta é um dos materiais restauradores mais pesquisados na Odontologia, visando
melhorias nas suas propriedades e aperfeiçoamento da técnica. Este trabalho tem o objetivo de avaliar a rugosidade
superficial de duas resinas compostas, micro-híbrida e nanoparticulada, após a ...
Abstract Objectives To compare the microtensile bond strength (µTBS) and depth of cure (DOC) of bulk-fill composites cured by monowave (MW) and polywave (PW) LED units using different curing times. Methodology Three composites were tested: Tetric EvoCeram Bulk Fill (TBF), Filtek Bulk Fill (FBF), and...
Objetivo:Investigar o perfil das publicações brasileiras em laser/LED de 2015 a 2019. Métodos: Foi realizado um estudo observacional, por meio de documentação indireta, através da análise dos trabalhos apresentados nas reuniões do SBPqO de 2015 a 2019. Os estudos foram classificados quanto à ins...
Abstract This study measured and compared exitance irradiance and power of 4 commercial dental light-curing units (LCU) (Elipar S10, Elipar DeepCure-S, Corded VALO and Bluephase Style) using different types of radiometers. The devices used to analyze the LCU were classified as either handheld analog (Hen...
El objetivo de este estudio fue analizar el comportamiento,
contracción volumétrica, de diferentes resinas
compuestas de fotopolimerización, expuestas a
variadas condiciones de incidencia lumínica. Se tomaron
volúmenes estandarizados de 7 resinas compuestas
(microhíbridas y nanohíbridas y nanopart...
Abstract Objective Since the transmittance of ceramics can influence the degree of conversion (DC) of resin cements, ceramics composition and shade should be considered in the selection of resin cement. This in vitro study aimed to evaluate the effect of the transmittance of different composition, opac...

Abstract Currently, there is no consensus in terms of defining the minimum radiant exposure values necessary for achieving adequate properties of composite resin. In addition, the long-term influence that radiant exposure has on the properties of composite resins is still questionable. Objective: The obj...
