Abstract :
Aim:The aim of this in vitro study was to analyze the effect of four beverages on surface roughness of two different types of resin composites (nano–hyid and micro–hyid) at different time intervals. Methodology:Eighty disc–shaped samples (8 mm×3 mm) were prepared using a custom made stainless steel mould. After 24 hours of storage, the samples were blotted dry using tissue paper and the preoperative readings for surface roughness (Ra) were obtained using profilometer. The samples were divided into two groups for the two composites [micro–hyid (Group 1) and nano–hyid (Group 2) n=40]. Forty discs of each material were again randomly divided into four subgroups, according to the four beverages used Coca–Cola, pH=1.57; Tea; Nimbooz, pH=2.32 and Whiskey (n=10). The samples in each group were immersed in the respective beverage for 10 minutes twice every day with a gap of 12hours. For the remaining part of the day, the samples were kept immersed in municipal water. This regimen was followed for 30 days. After 3o days the surface roughness was evaluated using same techniques as before immersion in the beverages. Results: Surface roughness of Micro hyid composite resin was significantly increased after immersion in Coca–Cola(p<0.001) Tea(p=0.016) and Whiskey(p=0.005) with p≤0.05 whereas with Nimbooz the surface roughness was not increased significantly (p=0.076). In nanohyid composites all four beverages increased the surface roughness significantly (p value for coca cola 0.010; for Tea 0.019; for Nimbooz 0.013 and for Whiskey 0.001)
