超强纤维固定牙外伤脱位对牙周指数的影响

背景：目前超强纤维在牙外伤脱位的修复固定中的临床应用还较少,而且已有的研究主要集中在短期疗效方面,对牙周的影响却鲜有报道。目的：对比研究超强纤维、牙弓夹板、方丝弓3种固定方法对外伤脱位恒前牙固定中的牙周指数变化,并了解国内超强纤维在口腔领域的研究概况。方法：60例恒前牙外伤脱位患者,随机分为3组,分别为超强纤维组,牙弓夹板组及方丝弓组。分别用3种方式进行固定后对比观察外伤牙牙周检测指标的变化情况,得出菌斑指数和牙龈指数,进行统计学分析比较。并在CNKI数据库中检索相关文献,对文献的发表情况、研究情况进行分析。结果与结论：超强纤维组与牙弓夹板组、方丝弓组的菌斑指数、牙龈指数在统计学上差异有显著性意义（P〈0.05）,超强纤维组明显优于牙弓夹板组、方丝弓组。超强纤维固定法是一种牙周刺激性小,易于清洁,美观舒适的脱位牙固定方法。然而目前国内关于超强纤维修复固定牙外伤脱位的文献数量还很少。

Effect of super fiber on the periodontal index after fixation of dental traumatic dislocation

BACKGROUND： Recently, the clinical application of super fiber in the repairing and fixation of dental traumatic dislocation is rare, while the existing research mainly focuses on the short-term efficacy, and the reports on the effect in periodontal is rare.OBJECTIVE： To comparative study the change of periodontal index of dislocated permanent anterior teeth fixed by super fiber, arch splint and edgewise bracket and to understand the domestic research on the super fiber in the oral field,METHODS： Sixty patients with dislocated permanent anterior teeth were randomly divided into three groups： super fiber group, arch splint group and edgewise bracket group. The changes of periodontal index of the traumatic tooth were comparatively observed after fixed with the three methods; the plaque index and gingival index were obtained for the statistical analysis and comparison. The related literatures were searched in CNKI database, and the publish situation and the research situation of the literatures were analyzed.RESULTS AND CONCLUSION： There were significant differences of the plaque index and gingival index between super fiber group, arch splint group and edgewise bracket group （P 〈 0.05）. The plaque index and gingival index in the super fiber group were significantly better than those in the arch splint group and edgewise bracket group. The super fiber fixation method is an effective method for the fixation of dislocated teeth with the advantages of smaller periodontium irritation, easy for clean and reliable performance. However, the domestic literatures on the dental traumatic dislocation fixed with super fiber are rare.
