Forty-three bicuspids which replaced successfully pulpotomized vital or non-vital primary molars, and twenty bicuspids, which erupted following unsuccessful pulpotomies requiring extraction of the preceding teeth, were examined for defects of position and enamel. In comparison with contralateral control teeth, test teeth in both groups showed an increased prevalence of rotation and enamel surface defects.
对43颗成功替代了经牙髓切断术处理的活髓或失活乳磨牙的双尖牙,以及20颗在牙髓切断术失败需要拔除前牙后萌出的双尖牙,进行了位置和釉质缺陷检查。与对侧对照牙相比,两组的受试牙均显示出旋转和釉质表面缺陷的发生率增加。
