Evaluation of the Optimum Brushing Force on Dental Plaque Removal and the Abrasive Effect of Brushing Force on Enamel Surface.

Evaluation of the Optimum Brushing Force on Dental Plaque Removal and the Abrasive Effect of Brushing Force on Enamel Surface: An in Vitro Study.

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

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: brushing force	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

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
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
