摘要 目的 检测接受固定矫治病人牙菌斑堆积情况。 方法 通过对120例正畸病例 (其中矫治前 ,矫治<6个月 ,矫治6~12个月 ,矫治>12个月各30例 )进行菌斑测试 ,分别对不同时期 ,不同牙位的菌斑指数进行比较。 结果 矫治前与矫治后各个阶段的菌斑指数有显著差异 (P<0.01)。矫治后各个阶段的菌斑指数无明显差异。菌斑指数 :上牙列>下牙列。前牙>后牙 ,右侧尖牙>左侧尖牙 ,右下双尖牙>左下双尖牙。上侧切牙菌斑值最大。 结论 固定矫治器严重妨碍口腔卫生 。 Objective TO evaluate the effects of dental plague with fixed orthodontic appliances.Methods The 120 patients orthodontic treatment with fixed appiliance were randomly divided into four groups(n=30 respectively) as follows: (1)pre-treatment.(2)three to six months.(3)six to twelve months(4)more than twelve months. Everyone was tested the plague index(PLI) with plague disclosing agent.Results The PLI in pretreatment was lower than that of the treatment(P>0.01. In each treatment phase PLI had no marked difference. The PLI of maxillary teeth were higher than that of mandibular teeth.Conclusion The fixed orthodontic appliances severely affected the oral health. Upper and left teeth hygiene is more worse than the counterparts. Doctors and patients should take steps to improve the oral hygiene.
