摘要
目的 :本实验通过观察正畸儿童固定矫治前后牙周临床指标的变化 ,以明确固定矫治器是否会对牙周健康造成影响。方法 :本实验选择 61名 12～ 16岁错牙合畸形的患者 ,3 0名患者为矫治前和矫治后半年 ,3 1名为矫治后半年 ,1年分别观察牙龈指数 (GI)、菌斑指数 (PLI)、软垢指数 (DI)、牙石指数 (CI)等临床牙周指标的改变。结果 :固定矫治器的放置可引起临床牙周指标显著增高 (矫治前后比较 ,P <0 .0 0 1) ,且随放置时间的增长 ,临床牙周指标显著增高 (矫治后半年和 1年比较 ,P <0 .0 0 1)。结论 :固定矫治器的放置可影响牙周组织的健康 。
AIM:To make clear if the fixed appliance will affect the periodontal health by observing that periodontal index changed before orthodontic treated and after treated.METHODS:Sixty-one cases of twelve to sixteen-year-old patients with malocclusion were randomly selected. 31 children had been treated for half year. 30 children should not been treated. Before treated and after treated,plaque index(PLI),gingival index (GI),debris index (DI),calculus index (CI) were assessed.RESULTS:After orthodontic treated, these values of periodontal index(PLI?GI?DI?CI) were significantly greater than those in untreated,and the longer the time of orthodontic treated was ,the greater it was.CONCLUSION:Fixed appliance placement will affect the periodontal health.Therefore, it is very important to strengthen the oral hygiene instruction to the people who receive orthodontic treatment.
