Brief 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

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


Outcome Measures

Primary Outcome Measures :
  1. optimum force [ Time Frame: 5 seconds ]
    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.
