| ABSTRACT Objective: Microleakage of the resin-based restorative materials has marked effect on the success of the restoration, and it depends on various factors including the type of restorative material and the curing device. Hence, this study was directed to assess the influence of three different curing devices on the microleakage of two resin-based restorative materials in anterior primary teeth. Material and methods: A total of thirty primary anterior teeth and used in this study. Class V cavities were ideally prepared and restored with two resin-based restorative materials (resin-modified glass ionomer cement (RMGIC), and GIOMER) according to manufacturer instruction. The restored teeth were divided into two equal main groups (n= 15) according to the type of resin restorative material as follow; Group A; teeth restored with RMGIC. Group B; teeth restored with GIOMER. Then, the samples of each main group were then subdivided into three equal subgroups (n=5) according to the type of the curing system (Quartz tungsten Halogen (QTH) light curing, Light emitted diode (LED) curing, and Argon laser). The restored teeth with class V cavities were subjected to a thermocycling (500 cycles between 5oC - 55oC for 60 seconds each with a dwell time of fifteen sec, simulating a 5-months of clinical exposure in the oral cavity) and were then evaluated for microleakage via the silver nitrate tracer penetration method. | ||||
