目的探讨全牙列牙合垫和超强纤维树脂固定外伤松动前牙的临床效果。方法前牙外伤患儿38例,随机分为2组,观察组20例采用全牙列牙合垫固定治疗,对照组18例采用超强纤维树脂固定治疗。4周后拆除固定装置,统计2组有效固定率,比较2组牙龈探诊出血(bleeding on probing,BOP)阳性率、舒适指数和操作时间。结果观察组有效固定率(95.0%)与对照组(94.4%)比较差异无统计学意义(P>0.05);治疗前观察组BOP阳性率(45.0%)与对照组(27.8%)比较差异无统计学意义(P>0.05);治疗2、4周,观察组BOP阳性率(35.0%,15.0%)低于对照组(66.7%,94.4%),差异有统计学意义(P<0.05);观察组操作时间[220.0(200.0,240.0)s]、舒适指数(1.900±1.021)低于对照组[1 077.5(1 020.0,1 090.0)s,5.830±0.857](P<0.01)。结论全牙列牙合垫固定和超强纤维树脂固定治疗儿童外伤松动前牙均可达到有效固定,但全牙列牙合垫固定治疗的操作时间、舒适度及治疗后患儿牙周健康程度优于超强纤维树脂固定。
Objective To investigate the clinical effect of total dentition occlusion pad and superfine fiber resin on anterior loosening of traumatic injury. Methods Thirty-eight children with anterior tooth trauma were randomly divided into two groups. Twenty patients in the observation group were treated with all-dentition occlusion. In the control group, 18 patients were treated with super-fiber resin fixation. After 4 weeks, the fixation devices were removed and the effective fixation rate was calculated. The positive rate of gingival bleeding episodes (BOP), comfort index and operation time were compared between the two groups. Results There was no significant difference in the effective fixation rate (95.0%) between the observation group and the control group (94.4%) (P> 0.05). The positive rate of BOP in the observation group before treatment was 45.0% (P> 0.05). The positive rate of BOP in observation group was lower than that in control group (66.7%, 94.4%, P <0.05) after treatment for 2 and 4 weeks. The observation group’s operation time [220.0 (200.0,240.0) s] and comfort index (1.900 ± 1.021) were lower than those of the control group [1 077.5 (1 020.0, 1 090.0) s, 5.830 ± 0.857] (P <0.01). Conclusion The total dentition occlusal pad fixation and super fiber resin fixation can effectively fix the anterior teeth with loosening of traumatic injury in children. However, the operation time, comfort and the periodontal health of children with orthodontic treatment Better than super-fiber resin fixation.
