Effect of diode laser and light-emitting diode (LED) activated bleaching with 35% hydrogen peroxide on microleakage of class-V composite restorations: An in vitro study
Introduction: Residual oxygen-free radicals of bleaching agents before composite restorations can increase microleakage in enamel and dentin margins, and also various bleaching techniques are being developed using light sources. The present study was conducted to compare the effect of diode laser bleaching and LED activated bleaching on the microleakage of composite restorations. Materials & M...
متن کاملEffect of Three Light Curing Protocols and Load Cycling on Microleakage of Class V Composite Restorations
Objective: Different methods have been suggested to overcome the polymerization shrinkage of composite restorations. Changing the light curing protocol to improve polymerization by using new light curing units is among these methods. The new devices are more efficient, portable and durable and produce less heat. This study aimed to assess the marginal microleakage of class V composite restora...
متن کاملThe Effect of Dental Bonding Agent of Excite on the Rate of Microleakage in Class V Amalgam Restorations
Aim: This study was done to evaluate the rate of microleakage in class V amalgam restorations in which the dental bonding agent (DBA) Excite was used as a sealer beneath the restorations. Methods: four amalgam restorative materials with commercial names of Dentam, Cinalux, Tytin and SDI (GS-80) were used. Seventy sound human premolars were selected and randomly divided into 4 groups of 15 teeth...
متن کاملThe Effect of Different Periods of Enamel Microabrasion on the Microleakage of Class V Glass-Ionomer Restorations
Objective: Removal of enamel superficial layer during microabrasion treatments may adversely affect sealing ability of the restorative materials. The aim of this study was to measure the effect of different periods of enamel microabrasion on the microleakage of class V glass-ionomer restorations. Methods: This in vitro experimental study was conducted on 96 Class V cavities which had been pr...
