Effect of Fruit Juices and Aerated Beverage on the Colour Stability and Surface Roughness of Composite Resins. An In-Vitro Study
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2017, Vol 2, Issue 3
Abstract
Background: One of the foremost challenges in restorative and aesthetic dentistry is to produce a restoration which looks natural and blends harmoniously with the oral environment. Defining aesthetics as “the art of the imperceptible”1, color stability can be the difference between success and failure. Color stability, the property of material to retain its original color over a period of time, in a specified environment, is an important property of many materials used in dentistry.2 However composites resins suffer in-service discoloration (staining) with time leading to patient dissatisfaction, additional time and money for replacement of restorations.3 Aim: The aim of the present study is to analyze the effect of two commonly consumed fruit juices (apple and orange) and an aerated beverage(Coca-Cola), on the surface roughness and colour stability of two different types of resin composites. Materials & Method: In the present study, one hundred and twenty disc- shaped resin composite specimens were fabricated using Z350 XT and P60 resin composites (sixty each). These specimens were subjected to staining in various solutions, namely artificial saliva, coca cola, orange juice (fresh), orange juice (p), apple juice (fresh) and apple juice (p) for time intervals of 1 day, 7 days, 14 days, 28 days and 56 days, and were examined for surface roughness and colour changes using a surface profilometer and spectrophotometer respectively. Results: The results of the present study show that there was a significant increase in surface roughness (Ra) and colour change (ΔE) in both the resin composite tested, at all the time intervals. Conclusion: The silorane based resin composite (P60) exhibited better colour stability and relatively lower surface roughness when compared to methacrylate based resin composites (Z350 XT) in fruit juices and an aerated beverage.
