目的比较三种不同治疗方法对年轻恒牙畸形中央尖患牙早期临床干预治疗的效果。方法选取2013年10月至12月上海市松江区中小学生体检中发现的未达咬合面畸形中央尖患者25例,分层随机抽样84颗患牙,分别采用单纯树脂覆盖法(A组,28颗)、窝沟封闭剂充填法(B组,28颗)以及改良多次调磨法(C组,28颗)治疗,并分别于术后1、3、6、12个月复查,记录不同治疗方法患者术中患牙敏感程度、术前术后X线片牙根发育情况和术后充填材料脱落情况。结果 A组、B组、C组治疗方法有效率分别为92.31%、96.00%、84.00%,经检验差异无统计学意义(P>0.05);A组患牙敏感率为3.57%,低于B组的57.14%和C组的32.14%,差异均有统计学意义(P<0.05),而B组和C组敏感发生率比较差异无统计学意义(P>0.05)。结论单纯树脂覆盖法和窝沟封闭剂充填法能有效防止年轻恒牙畸形中央尖折断或牙髓病变,单纯树脂覆盖法较少引起畸形中央尖患牙敏感发生。
Objective To compare the effects of three different treatments on the early clinical intervention of young permanent tooth deformities. Methods From October to December 2013, 25 cases of central eyelid deformities were detected in the primary and secondary school students in Songjiang District, Shanghai. Eighty-four teeth were stratified randomly and were randomly divided into two groups: group A The fissure sealant filling method (group B, n = 28) and modified multiple grinding (group C, n = 28) were performed and were reviewed at 1, 3, 6 and 12 months after operation Treatment of patients with intraoperative tooth sensitivity, preoperative and postoperative X-ray root development and postoperative filling material shedding. Results The effective rates of treatment in group A, group B and group C were 92.31%, 96.00% and 84.00%, respectively. There was no significant difference between the two groups (P> 0.05). The sensitivity of group A was 3.57% (P <0.05). However, there was no significant difference between group B and group C (P> 0.05). Conclusions The simple resin-covered and fissure-sealant filling method can effectively prevent the young spondylolisthesis from breaking or distracting. The simple resin-covered method is less sensitive to tooth deformity.
