the Optimum Brushing Force for Dental Plaque Removal and the Effect of Brushing Force on Enamel Characteristic
Conditions
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
Interventions
PROCEDUREbrushing 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

Primary
| Measure | Time frame | Description |
|---|---|---|
| optimum force | 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. |
