This paper presents a controlled clinical trial to compare the effects of 2 programs for maintenance of oral hygiene after periodontal treatment. Oral hygiene instruction using a self-inspection plaque index was compared to traditional instruction using professional monitoring of disclosed plaque. 31 periodontal recall patients were randomly assigned to 2 groups. 15 patients in the self-inspection group were provided a manual that taught scoring of disclosed plaque on 6 teeth, a lighted dental mirror, and disclosing wafers. 16 patients in the traditional group were shown disclosed plaque in their own mouths, and were given feedback regarding oral hygiene skills. Instruction was given initially, at 2 weeks, at 1.5 months and at 3 months. The teeth were scaled at the start and at 3 months. Disclosed dentogingival plaque (before and after brushing), gingival bleeding on probing, and oral hygiene skills were assessed at 0, 1.5, 3 and 6 months. Initial mean plaque scores for only the self-inspection group decreased significantly at 1.5 months and were maintained throughout the study; however differences between groups were not observed at any time except at baseline. Gingival bleeding scores were low throughout the study for both groups. Results provide some evidence for the effectiveness of self-evaluation of disclosed plaque as a means for improving oral hygiene behavior in already-motivated patients.
本文介绍了一项对照临床试验，以比较两种牙周治疗后口腔卫生维护方案的效果。使用自我检查菌斑指数的口腔卫生指导与使用专业监测已染色菌斑的传统指导进行了比较。31名牙周复查患者被随机分为两组。自我检查组的15名患者获得了一本手册，该手册教授对6颗牙齿上已染色菌斑的评分方法、一个带照明的牙镜和染色片。传统组的16名患者在自己口中展示了已染色菌斑，并得到了关于口腔卫生技能的反馈。指导在初始阶段、2周、1.5个月和3个月时进行。在开始时和3个月时对牙齿进行洁治。在0、1.5、3和6个月时评估已染色的龈牙菌斑（刷牙前后）、探诊时牙龈出血情况和口腔卫生技能。仅自我检查组的初始平均菌斑评分在1.5个月时显著下降，并在整个研究过程中保持；然而，除了基线时，两组之间在任何时候都未观察到差异。在整个研究过程中，两组的牙龈出血评分都很低。结果为已染色菌斑自我评估作为改善有积极性患者口腔卫生行为的一种手段的有效性提供了一些证据。
