Clinical Trial 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

Outcome

Type Measure Description Time frame Safety issue
Primary optimum force The toothbrush holder was adjusted allowing toothbrush bristle to press onto the tooth surface until the loading monitor indicated the designated vertical loading force. Loading force was applied from a minimum of 1 N, with an increment of 1 N to a maximum of 6 N. The optimum force which remove all dental plaque from tooth surface will recorded. 5 seconds
