Comparative Surface Roughness Evaluation of a Novel Aesthetic Restorative Material using Profilometer - An In Vitro Study

Aim: To evaluate and compare the surface roughness of nano ionomer, microhybrid composite, and resin modified glass ionomer cement. Method: A total of 30 PVC moulds of dimension (diameter 8mm height 2mm) were prepared. The total of 30 specimens was divided into three groups each consisting of 10 discs each. Group110 discs made of microhybrid composite (Z250, 3M ESPE, St. Paul, MN, USA), Group 210 discs made of resin modified GIC (Fuji II LC, GC), Group 3-10 discs made of nano ionomer (Ketac N100, 3M ESPE, St. Paul, MN, USA). After polymerization the discs were subjected to finishing and polishing using Sof-lex finishing polishing kit(3M ESPE, St. Paul, MN, USA). After finishing the specimens were thoroughly washed and air dried before subjecting them to profilometric analysis. The profilometric values were statistically analyzed using ANOVA and Tukey Hoc tests. Results: The surface roughness values were statistically significant between group 1 and group 2 and between group 2 and group 3 but there was no statistically significant difference between group 1 and group 3.
