Of twenty-five cases presented here, eighteen were boys and seven were girls who required apexification through December 1986. Nine teeth were considered treatment failures after a 9.5-year follow-up period. With these nine cases, however, five teeth to date have had successful endodontic treatment. Additional follow-up time (5-8 years) is required to evaluate the final outcome of pulp canal therapy applied in cases of traumatized maxillary permanent incisor teeth, with incomplete root formation.
本文所呈现的25个病例中，截至1986年12月，有18名男孩和7名女孩需要进行根尖诱导成形术。经过9.5年的随访期，9颗牙齿被视为治疗失败。然而，在这9个病例中，截至目前已有5颗牙齿接受了成功的根管治疗。对于外伤导致的上颌恒切牙牙根发育不全的病例，应用牙髓根管治疗的最终结果仍需额外的随访时间（5 - 8年）来评估。
