Abstract :
Aim: To evaluate influence of tooth brushing – mouth rinse cycling (TMC) on surface roughness of two resin composites (Nanohybrid-Z250 & Nanofilled-Z350).
Materials and Method: 80 disc shaped specimen of two composite resins ?Nanofilled – FiltekTM Z-350 XT(3M ESPE, U.S.A. Shade A2); Nanohybrid FiltekTM Z-250 XT(3M ESPE,U.S.A. Shade A2? were prepared (each-40) using teflon ring matrix & divided into 4 groups (n=10) according to mouthrinses to which they were subjected: Listerine(Alcoholic), Rexidine Plus (Alcohol free), Betadine Mint (Iodine) & Artificial saliva (control). Powered toothbrush mounted on standardized jig was used to deliver constant brushing strokes. Specimens were subjected to TMC for four weeks. Surface roughness was evaluated using a surface roughness tester.
Results: The result of the MANOVA (Statistical analysis) showed that the Nanofilled resin(Z-350) presented lower surface roughness than Nanohybrid (Z-250) (p
