Subapical osteotomy of the anterior mandible was carried out on 10 adult Macaca Irus monkeys with and without open bite. Teeth were extracted at 8 weeks, 12 weeks, 24 weeks and 1 year after surgery and the pulps examined histologically. No normal pulps were found. Progressive fibrosis and calcification was noted in all teeth. Patent pulp blood vessels were found up to 24 weeks after surgery. Pulp damage to teeth distal to the osteotomy site was found in 50% of cases. Control teeth extracted from the opposing jaw at the same intervals were all found to have normal pulps.
对10只成年食蟹猴进行了下颌前部根尖下截骨术，其中部分猴子存在开颌情况，部分没有。术后8周、12周、24周和1年分别拔除牙齿，并对牙髓进行组织学检查。未发现正常牙髓。所有牙齿均出现进行性纤维化和钙化。术后24周内均发现牙髓血管通畅。截骨部位远端牙齿的牙髓损伤在50%的病例中出现。在相同时间间隔从对侧颌骨拔除的对照牙齿均发现牙髓正常。
