Abstract
Aim: The goal of this study was to see how accelerated artificial ageing (AAA) affected the colour of composite resins used in dentistry. Materials and Methods: We piloted an invitro study with 2 nanofilled Premise and Filtek Z350 and microfilled Spectrum TPH. A total of 90 specimens equally distributed for the three composites were selected. The color measurements were obtained with a Spectrophotometer before and after invitro aging. Data were analyzed using chi square test with p <0.05. Results: There was observed a significant variation in the shades of all the composites. There was a significant variation between the Nanocomposites and the microfilled composites. Conclusions: All composite resins depicted a color change and the size of the particles may have impacted the staining of the composites in vitro. Key words: Color, Composite Resins, Aging.
