Influence of Photoinitiator on Accelerated Artificial Aging and Bond Strength o...
Righi,Helouise; Costa,Ana Rosa; Oliveira,Dayane Carvalho Ramos Salles de; Abuna,Gabriel Flores; Sinhoreti,Mario Alexandre CoelhoAbstract The goal of this study was to evaluate in vitro the effect of the photoinitiator phenylpropanedione (PPD), alone or combined with camphorquinone (CQ), on color stability of photoactivated resin cements and their bond strength to ceramics using a micro-shear test. Four resin cements were used: a commercial brand cement (RelyX Veneer®) and 3 experimental cements with different types and concentration of ...
Influence of Photoinitiator and Light-Curing Source on Bond Strength of Experim...
Segreto,Dario Raimundo; Naufel,Fabiana Scarparo; Brandt,William Cunha; Guiraldo,Ricardo Danil; Correr-Sobrinho,LourençoAbstract This study evaluated the bond strength (BS) of experimental resin cements formulated with different photoinitiators when activated by two kinds of light-curing units (LCUs) through a ceramic material. Seven resin blends with different camphorquinone (CQ) and/or phenylpropanedione (PPD) concentrations (weight) were prepared: C5: 0.5% CQ; C8: 0.8% CQ; P5: 0.5% PPD; P8: 0.8% PPD; C1P4: 0.1% CQ and 0.4% PP...
Clinical strategies for esthetic excellence in anterior tooth restorations: und...
Nahsan,Flavia Pardo Salata; Mondelli,Rafael Francisco Lia; Franco,Eduardo Batista; Naufel,Fabiana Scarparo; Ueda,Julio Katuhide; Schmitt,Vera LuciaDirect composite resin restorations have become a viable alternative for patients that require anterior restorative procedures to be integrated to the other teeth that compose the smile, especially for presenting satisfactory esthetic results and minimum wear of the dental structure. Technological evolution along with a better understanding of the behavior of dental tissues to light incidence has allowed the de...
Effect of deproteinization and tubular occlusion on microtensile bond strength ...
Baseggio,Wagner; Consolmagno,Elaine Cristina; Carvalho,Flávia Lunardelli Negreiros de; Ueda,Julio Katuhide; Schmitt,Vera Lucia; Formighieri,Luis AlbertoDentin adhesion procedure presents limitations, especially regarding to lifetime stability of formed hybrid layer. Alternative procedures have been studied in order to improve adhesion to dentin. OBJECTIVE: The aim of this study was to evaluate in vitro the influence of deproteinization or dentin tubular occlusion, as well as the combination of both techniques, on microtensile bond strength (µTBS) and marginal ...
