摘要
目的回顾分析弹性纤维夹板治疗恒前牙水平根折的临床效果,为临床治疗提供依据。方法收集54颗恒前牙水平根折患牙的病例资料,均已随访1~2年,分析根折患牙保存率和牙髓存活率,并进一步分析根折部位(根颈1/3、根中1/3、根尖1/3)、牙根的发育阶段(成熟恒牙、年轻恒牙)、断端的移位程度(<1 mm、1 mm、>1 mm)对根折愈合情况和牙髓存活率的影响。结果 54颗根折患牙均根据国际牙外伤协会治疗指南治疗,应用弹性纤维夹板固定后,牙齿保存率为90.7%,牙髓存活率为75.9%,其中硬组织愈合33颗,硬组织愈合率61.1%。根折部位、牙根的发育阶段、断端的移位程度对根折愈合类型、牙髓存活率的影响差异均无统计学意义(P> 0.05)。结论弹性纤维夹板适应证广泛,除根折线位于牙槽嵴顶以上的患牙,其余前牙水平根折均可尝试采用弹性纤维夹板固定治疗,并能够取得良好的预后。
Objective To analyze the clinical effect of flexible fiber splint on traumatized permanent teeth with horizontal root fractures and to provide the basis for clinical treatment. Methods The case data of 54 permanent root anterior teeth with horizontal root fractures were collected. Patients with affected teeth were followed for 1 to 2 years to analyze the root fractures. The preservation rate and pulp survival rate were analyzed, and further analysis was performed on the effects of the root fracture location(cervical 1/3, Mid-root, apical 1/3), root development stage(mature permanent teeth, young permanent teeth), dislocation of the coronal fragment(<1 mm, 1 mm, > 1 mm) on root fracture healing and dental pulp survival. Results A total of 54 teeth with root fractures were treated according to the International Dental Trauma Association Treatment Guidelines. After the application of flexible fiber splint fixation, the tooth preservation rate was 90.7%, and the pulp survival rate was 75.9%, the hard tissues healing rate was 61.1%(33/54). There were no significant differences in the locations of root fractures, the developmental stages of the roots, or the degrees of dislocation of coronal fragment on the types of root fracture healing or dental pulp survival(P > 0.05). Conclusion The flexible fiber splint has a wide range of indications. Except for affected teeth with the root fracture located above the alveolar crest, other types of horizontal root fractures in anterior teeth can be treated with flexible fiber splint fixation and can achieve a good prognosis.
