Summary

Objective 1. To determine the optimum brushing force for dental plaque removal. 2. To investigate the effect of brushing force on enamel characteristic. Hypothesis H0 : Structural tooth loss is not significantly different between before and after brushing with excessive force on enamel surface. H1 : Structural tooth loss is significantly different between before and after brushing with excessive force on enamel surface. Study design: Experimental study

Conditions

• the Optimum Brushing Force for Dental Plaque Removal and the Effect of Brushing Force on Enamel Characteristic

Interventions

Type	Name	Description
PROCEDURE	brushing force	Using duplication method, vertical force was applied from 1-5.5 N in linear mesial-distal brushing motion at 4 strokes per second for 5 seconds Force was increase 0.5 N in every testing until plaque was completely removed from enamel surface
