目的 :评估刷牙时间与菌斑控制水平的关系。方法 :选菌斑指数 (PLI) 1～ 3,龈缘线结石指数(MLCI) 1～ 3的慢性龈炎和慢性牙周炎患者共 6 6名 ,所有患者经常规全口超声洁治后 15～ 2 0d复诊。用2 0 g/L碱性品红染色后再用清水漱口 ,指导患者用颤动旋转法刷牙 ,分别记录刷牙前 ,刷牙 3、5、8、10min时的菌斑指数。结果 :刷牙前菌斑附着率高达 79.15 % ,用正确的方法刷牙 10min时 ,菌斑附着率仍高达 17.36 %。结论 :用正确的方法刷牙
Abstract AIM:To evaluate the relationship of brushing time and the level of plaque control.METHODS: We randomly selected 66 patients with chronic gingivitis and chronic periodontitis whose PLI and MLCI both range from 1 d to 3. 15 to 20 d before the test, every patient was offered with complete supersonic supragingival scaling. On the test day, we instructed the patients to brush their teeth with tremor and rolling brushing method whose PLI were then recorded respectively before brushing, after 3 minutes′brushing, after 5 minutes′brushing, after 8 minutes′brushing and after 10 minutes′brushing by dying the plaque through rinsing their mouths with 20 mL/L basic magenta.RESULTS:The average rate of plaque agglomeration before brushing was up to 79.15% while after 10 minutes′ brushing, it was only 17.36%. CONCLUSION:Only 10 minutes′brushing with correct brushing method can help the patients to achieve the effective range of plaque control.
