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.
