Abstract
The purposes of this study were to evaluate the microleakage of class V composite resin restorations utilizing the different curing lights, to assess the flowable resin, FiltekTMFlow (3M Dental Products, USA) and composite resin, FiltekTM Z250(3M Dental Products, USA) which need 20s curing time for halogen light could replace Z100TM Restorative(3M Dental Products, USA) for the microleakage, and to evaluate the effect of adhesive resin on marginal microleakage. Light curing units used in this study were conventional halogen light, XL3000(3M Dental Products, USA) and plasma arc light, Flipo(Lokki, France). Class V cavities were prepared and each cavity was filled with each composite resin. After being filled, the teeth were stored in distilled water, polished, thermocycled and soaked in 1% methylene blue solution. Following results were obtained from evaluation of the sectioned surface. 1. There was no statistically significant difference in microleakage of FiltekTMFlow and FilkTMZ250 between two kinds of curing units(p>0.05). 2. Flowable resin, FiltekTMFlow showed more microleakage than Z100 and FiltekTMZ250 regardless of curing units(p<0.05). 3. Adhesive resin reduced the microleakage of composite resin in both halogen light and plasma arc light(p<0.05).
Key Words: Microleakage, Composite resin, Halogen light, Plasma light, Adhesive resin
