简要总结

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.

主要结局

optimum force

时间窗: 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.
