“左手”によるイメージブラッシングとバーチャルブラッシングの角度による困難度の比較研究

摘要

Teeth brushing of plaque control behavior depends on the condition of Three conditios. The first part is the brain, namely “left hemisphere and right hemisphere”. The second part is “nervous system”. The third part is the “muscle system”. Real brushing（RB） with a toothbrush uses all the three parts directly. By the way, IB： image brushing　uses only the first part, namely the brain. VB： virtual brushing with a pen in the right hand use all three parts as RB. The first hypothesis is the subjective difficulty of VB is higher than that of IB. In other words, VB is effective than IB. The second hypothesis is at VB, oblique line“ 120” is most easy,“ 0 or 180” is middle and “60” is most difficult. The results confirmed the above two hypotheses.
