| 目的 比较2 种夹板固定方法对外伤牙及其邻牙牙周组织的影响。 方法 采用随机分组对照试验方法, 对外伤的44 颗恒前牙, 均分2 组进行夹板固定保持4 周, 其中A 组为实验组(玻璃纤维树脂夹板组), B 组为对照组(钢丝加树脂夹板组)。于固定后1 周、4 周(拆夹板时)和拆夹板后2 个月复查, 检测患牙的近中邻牙牙周指数(菌斑指数, 牙龈出血指数和牙周探诊深度)的改变, 进行统计学分析。结果 固定后1 周和4 周玻璃纤维树脂夹板组的各项牙周指数明显低于对照组, 经统计学分析, 其差异具有显著性意义 (P<0.05), 而拆夹板后2 个月2 组的差异无统计学意义(P=0.05)。 结论 玻璃纤维树脂夹板应用于外伤牙的固定对牙周的不良影响最小。 |

| Objective To compare effects of two different fixed techniques on the periodontium of traumatic teeth. Methods 44 traumatic permanent anterior teeth were randomly divided into 2 groups evenly (22 teeth per group). Group A were fixed by glass-fiber resin splint (everStick net), group B were fixed by steel wire resin splint. Each splint was kept for 4 weeks. All the cases were followed up at the interval of 1 week after fixation, 1 and 3 months after the fixation. The periodontal index (include PLI， BI ，PD) was observed. Evaluation was carried out by analysis of statistics. Result Each index of Group A was obviously lower than that of Group B. Clinical effects between 2 groups was significantly different (P<0.05) at first and second time. Conclusions The negative effect of everStick on periodontium of traumatic tooth is of the lowest. |
