Influence of types of curing lights on Shade stability of Dental nano-filled Restorations (original) (raw)

Abstract

Title: Influence of types of curing lights on Shade stability of nano-filled Dental Restorations. Aim and Objective: This study is to investigate the variation in shade of nano-filled resin composite restorations cured with QTH and LED light curing systems and evaluating the color stability in response to the beverages as an aging medium. Materials and Methods: In this in-vitro study four different restorative materials were exposed to QTH and LED light curing systems. Ten specimens were prepared for each curing light. Ten specimens were prepared from each material for each type of light cure system. Teflon moulds (Figure 1), measuring 6mm internal diameter by 3mm height will be used to produce the specimens. Shade was examined by VITA digital easyshade guide 3 times before and after curing for each sample mould. Specimens will be stored in an incupator for 24 hours before aging in beverages ( Tea, Coffee, Karkaday, Yansoon). Following these 5 specimens from each material cured with...
