目的探讨预防性充填治疗上颌侧切牙畸形舌窝的临床效果。方法选择58名9~12岁上颌侧切牙患有畸形舌窝的儿童进行预防性充填,每一位患儿的左侧上颌侧切牙采用流动树脂充填作为实验组,右侧上颌侧切牙采用玻璃离子充填作为对照组,术后随访两年,观察畸形舌窝内充填体有无脱落及微渗漏,患牙有无继发龋、牙髓炎及根尖周炎,进行疗效评价。结果 2年后复查,实验组58颗牙,成功54例,成功率93.1%,对照组58颗牙,成功41例,成功率70.7%,两组比较差异有统计学意义(P<0.01)。结论采用流动树脂预防性充填上颌侧切牙畸形舌窝是一种可靠的、保留率高的、继发龋低的、利于推广的治疗方法。
Objective To investigate the clinical effect of prophylactic filling in the treatment of maxillary lateral deformity. Methods Fifty-eight children aged 9-12 years old with maxillary lateral incisors were selected for prophylactic filling. The left maxillary lateral incisors of each child were filled with flowing resin as the experimental group. The right maxillary incisors were treated with glass ion Filling as a control group, follow-up for two years after surgery, to observe the fossa tongue fossa with or without shedding and microleakage, with or without secondary dental caries, pulpitis and periapical periodontitis, the efficacy evaluation. The results of two years after the review, the experimental group of 58 teeth, 54 cases of success, the success rate of 93.1%, the control group of 58 teeth, 41 cases of success, the success rate of 70.7%, the difference between the two groups was statistically significant (P <0.01). Conclusion The use of flowable resin to prophylactically fill the maxillary incisor deformity tongue socket is a reliable, high retention rate, low secondary caries, and promote the promotion of treatment.
