摘　　要：目的观察釉质成形预防性树脂修复法预防年轻前磨牙畸形中央尖折断的临床效果,并与一次性磨除间接/直接盖髓后树脂修复法作一比较。方法选择口内前磨牙畸形中央尖对称性萌出且未达咬合平面的患儿20例,62颗患牙,随机分为两组:釉质成形预防性树脂修复组(即树脂加固组)和一次性磨除间接或直接盖髓后树脂修复组,每组各31颗患牙,随访观察1年。结果釉质成形预防性树脂修复组未发现有失败病例,一次性磨除组31颗患牙中有4颗失败,成功率为87.10%,二者差异无统计学意义(P>0.05)。结论早期发现畸形中央尖患牙,并在其未达咬合平面之前应用釉质成形预防性树脂修复方法加固畸形中央尖,可以有效预防畸形中央尖的折断,保证其牙根正常发育。Objective To compare the clinical effects between two methods for preventing the fracture of central cusp deformity on immature premolars. They were enamoplasty preventive resin restoration（ or composite resin strengthening） technique and resin restora tion after oneoff grinding and indirect or direct pulp capping respectively. Methods 20 child patients who had central cusp deformity on the premolars bilaterally were enrolled. Teeth whose central cusp had erupted but not reached the ocelusal plane were divided into two groups randomly, enamoplasty preventive resin restoration group（ namely resin strengthening group） and resin restoration after one off grinding and indirect or direct pulp capping group. Each group had 31 teeth. All the patients were followed up for one year. Results No tooth was found failed in the group of enamoplasty preventive resin restoration. Among the 31 teeth treated by oneoff grinding method ,4 failed, and the success rate was 87.10%. There was no statistical difference between the two methods （P 〉 0.05 ）. Conclu sions Noticing abnormal central cusp ear/y and applying enamoplasty preventive resin restoration to strengthen abnormal central cusp before the teeth reached the occlusal plane can effectively prevent the fracture of abnormal central cusp, and ensure normal development of tooth.
