During extraction of the primary mandibular right second molar in an 11-year-old girl, the unerupted second premolar was accidentally extracted. Clinical and radiographic examination showed that the immediately replanted immature premolar was not oriented and positioned correctly. Four hours later, treatment consisted of manual extrusion of the permanent tooth bud, rotation, and gentle repositioning into its original position. Adequate replantation was confirmed by a post-operative radiograph. After 2 years and 4 months, clinical examination revealed normal, healthy appearance of the replanted tooth, no sensitivity to percussion, no tenderness to palpation, and a slight response to a cold pulp sensibility test. A radiograph showed completely developed root with closed apical foramen, slightly irregular root morphology and shorter root length, complete obliteration of the pulp, and no signs of periapical pathosis.
在一名 11 岁女孩拔除右侧下颌第一磨牙时，意外拔出了未萌出的第二前磨牙。临床和影像学检查显示，即刻再植的未成熟前磨牙未定向且位置不正确。4 小时后，治疗包括手动挤压恒牙胚，使其旋转并轻轻复位到原来的位置。术后 X 线片证实了充分的再植。2 年零 4 个月后，临床检查显示再植牙外观正常、健康，无叩诊敏感，无触压痛，冷牙髓感觉测试稍有反应。X 线片显示根尖孔完全封闭的发育完全的根，根形态略不规则，根长较短，牙髓完全消失，无根尖病变迹象。
