Abstract

Abstract:

BACKGROUND: It is believed that the splintage can promote periodontal tissue repair and improve the prognosis of loose teeth. However, the force of the splint is associated with the rigidity of the splint and adaptation between the teeth and the splint.

OBJECTIVE: To evaluate the therapeutic effects of the nylon composite resin periodontal splint, the fiber-reinforced composite periodontal splint and the bracket periodontal splint on the treatment of severe periodontitis of the mandibular anterior teeth.

METHODS: Seventy-two patients with severe periodontitis of the mandibular anterior teeth were randomized into 3 groups, with 24 cases in each group: nylon composite resin periodontal splint, fiber-reinforced composite periodontal splint and bracket periodontal splint groups. The clinical effects of the three kinds of periodontal splints and periodontal indexes were compared at 1, 6 and 12 months after splinting.

RESULTS AND CONCLUSION: The clinical effects in the group of the fiber-reinforced composite periodontal splint were significantly better than those in the other two groups at 1, 6, 12 months, which were 100%, 100% and 95.8%, respectively. The plaque index, bleeding index, and pocket depth were worse in the group of the nylon composite resin periodontal splint than the other two groups (P < 0.05). Results suggest that the fiber-reinforced composite periodontal splint is preferred to preserve the loosened teeth with severe periodontitis．

Figures/Tables 3

2.1 受试者数量分析试验共纳入72例患者，均获得12个月的随访，全部进入结果分析。 2.2 基线资料分析经比较3组患者的年龄、性别、患牙位置、诊断为重度牙周病的标准差异无显著性意义(P > 0.05)，见表1。 2.3 效果或结局分析临床疗效评价：据疗效评定标准，固定后1个月3组疗效比较差异无显著性意义(P > 0.05)，固定后6个月3组疗效比较差异无显著性意义(P > 0.05)，固定后1年3组疗效差异有显著性意义(P < 0.05)，超强玻璃纤维组最高，尼龙丝组最低,经过两两比较发现，正畸托槽组与玻璃纤维组1年后疗效差异无显著性意义(P > 0.05)，而尼龙丝组分别与正畸托槽组和玻璃纤维组比较差异均有显著性意义(P < 0.05，超强玻璃纤维组最高，尼龙丝组最低)，见表2。牙周观察指标：菌斑指数，出血指数，牙周袋深度：实验结果显示，治疗前3组各项牙周观测指标差异无显著性意义(P > 0.05)；3组固定后1个月各项牙周观测指标差异无显著性意义(P > 0.05)；固定后6个月、1年尼龙丝组各项牙周指标最差，与正畸托槽组及玻璃纤维组比较，差异均有显著性意义(P < 0.05)，超强玻璃纤维组最好，尼龙丝组最差，而固定后6个月、1年正畸托槽组与玻璃纤维组各项牙周观测指标比较差异无显著性意义(P > 0.05)，见表3。患者治疗前及治疗后1年X射线片比较见图1。 2.4 不良反应 3种材料均未发生局部炎症，刺激反应，过敏反应，组织增生；亦无全身反应：有无炎症和过敏现象及免疫反应等全身反应。 2.5 可能影响结果的因素受访者中11例男性患者和1例女性患者有吸烟史，在随访过程中未戒除吸烟的不良行为，因考虑到吸烟是牙周病的诱发因素之一所以可能会对结果造成影响；另正畸托槽组有5例患者出现不同程度的托槽脱落现象，虽及时给予重新黏结，但对结果可能造成影响。"
