摘　　要：目的　比较观察刷牙后残留菌斑的再生长或牙面重新形成新菌斑的动态变化。方法　 6 0位志愿者刷牙前和刷牙后 0、4、8、12和 2 4h ,以Rustogi等改良Navy菌斑指数记录 6个指数牙的菌斑分布情况。结果　刷牙后 4h ,所有区的菌斑指数与刷牙后 0h比较均有显著差异 (P <0 .0 1)。刷牙后 2 4h所有区的菌斑指数与刷牙前己差异不显著 ,即菌斑指数己恢复到刷牙前水平 ,仅光滑区菌斑指数与刷牙前仍有显著差异 (P <0 .0 1)。结论　现有的习惯刷牙方法刷牙 4h后牙面菌斑与刷牙后即刻比较己有显著差异 ,龈缘区、邻间隙区是菌斑快速再生长或重新形成的区域。Objective To evaluation the development of dental plaque after toothbrushing. Methods 60 Subjects were screened for dental plaque on the 6 index teeth, using the Rustoqi's repaired Navy's plaque index before and after toothbrushing 0 h, 4 h, 8 h, 16 h, 24 h after toothbrushing. Results There was significantl difference (P<0.01) then every area of tooth plaque between 0 h and 4 h after toothbrushing. There was no significant difference (P>0.05) on tooth plaque between before toothbrushing and 24 h after toothbrushing except plaque of smooth surfaces. Conclusion The dental plaque was recovered 24 h after toothbrushing. The fast recovering area is cervied and interprocimal areas.
