摘要: 目的：探讨临床固定矫正治疗中患者牙龈炎发生的原因。方法：固定正畸矫正患者172例，分为12～17岁组和18～22岁组，2组中又各自随机分为实验组和对照组。矫正前牙龈指数(GI)为0，戴固定矫治器6个月后检查牙龈情况，测定GI值，比较2组人群患牙龈炎的比率及各对照组与实验组牙龈炎的情况。结果：18～22岁组牙龈炎发生率低于12～17岁组，差异有统计学意义(P<0.05)。12～17岁组中实验组与对照组牙龈炎发生率差异有统计学意义(P<0.05)，18～22岁组中实验组与对照组差异无统计学意义(P>0.05)。结论：在固定正畸治疗期间，口腔卫生宣传教育及保健对降低正畸治疗中牙龈炎的发生率有重要作用。关键词： 固定矫正；牙龈炎；患病率

Abstract：Objective: The purpose of this study was to determine the causes of gingivitis in fixed orthodontic patients. Methods: The sample consisted of 172 cases, which were divided into 12—17y and 18—22y group, each group consisting of test group and control group, Gingival index(GI) was recorded for each individual patient, before fixed orthodontic appliances were inserted and the sixth month after insertion. Results: It was found that there was significant lower GI in 18—22y group than in 12—17y group, P<0.05. In 12—17y group, the test group had significant lower GI than that in control group; In 18—22y group, there was no significance difference between the test group and control group, P>0.05. Conclusion: The pilot study suggests that oral health care allowed for favorable treatment responses in gingivitis patients with fixed orthodontic appliances. ......
