A study was undertaken to evaluate the long term results of root resections. Records of 100 patients who had undergone root resections 10 years prior to the study were reviewed. Although the immediate postoperative results were gratifying, they were not always lasting. Eighty-four per cent of the failures occurred after 5 years. Most failures were in the mandibular arch and derived from reasons other than inflammatory periodontal disease. Suggestions are made as to how to improve the prognosis of resected teeth.
一项研究旨在评估牙根切除术的长期效果。回顾了100例在该研究开展前10年接受过牙根切除术患者的记录。尽管术后即刻效果令人满意，但并不总是持久的。84%的失败发生在5年后。大多数失败发生在下颌牙弓，且原因并非炎性牙周病。针对如何改善被切除牙齿的预后提出了建议。
