Comparative Evaluation of Three Different Types of Tooth Brush on Surface Abrasion of Enamel & Nanohybrid Composite - An in Vitro Study

Abstract

To evaluate& compare the ability of different tooth brush systems on the surface abrasion of enamel N Group 2(n=10) brushed with zig-zag bristles tooth brush , Group 3 (n=10)with powered tooth brush & Group4 (n=5) was taken as control group. A commercially available dentifrice was used throughout the study. A single specimen was brushed for 2 times daily for 2 min period for 1 week using a customized brushing apparatus. The pre- and post-roughness value change were analyzed and recorded & were analused using Wilcoxon ,Kruskal Wallis & Mann Whitney U test. Results: There was no statistical significant difference seen on enamel & on composite in all the four groups that is, all the three groups performed equally without any statistical significant difference.
