Significance The California Regional Primate Research Center routinely performs crown amputation with vital pulpotomy on maxillary canine teeth of adult male (_ 7 years of age) rhesus macaques in order to reduce self-trauma and injury to staff or cage-mates. The failure rate of this procedure is anecdotally high at the CRPRC. Objectives Crown amputation with pulpotomy will be compared to an alternative technique, which consists of amputating the crowns subgingivally and suturing a mucogingival flap over the root and exposed vital pulp. Results will be evaluated clinically and radiologically at three months and one year postoperatively. Results Crown amputation with pulpotomy on maxillary canine teeth was performed on 7 animals, and subgingival amputation on 13 animals. The preliminary results indicate an unacceptably high failure rate of the latter procedure, and this technique will not be used any further. Appropriate therapeutic measures were taken to treat the affected animals. No failures were noted thus far in the animals that underwent crown amputation with pulpotomy. Future Directions Long-term results of crown amputation with pulpotomy and refinement of this technique to minimize the failure rate. KEYWORDS crown amputation, pulpotomy, root retention

加州地区灵长类动物研究中心 常规进行牙冠切断术，并在上颌骨进行活髓切断术 成年雄性（7岁）恒河猴犬齿的顺序 以减少自我创伤和对工作人员或笼友的伤害。 失败 在CRPRC，这种程序的发生率很高。 目标 冠切断术与活髓切断术将被比较， 技术，其中包括切断牙冠龈下， 在牙根上覆盖一个牙龈粘膜瓣，露出活髓。 结果将在三个月后进行临床和放射学评估。 术后3个月和1年。 结果牙冠切除术 对7只动物的上颌尖牙进行活髓切断术， 龈下截肢术13例。 初步结果 表明后一个过程的不可接受的高失败率， 并且将不再使用该技术。 适当 采取了治疗措施来治疗受影响的动物。 没有 到目前为止，在接受牙冠治疗的动物中观察到失败 用活髓切断术进行截肢。 未来的方向 冠切断术与活髓切断术，并改进了这项技术， 尽量减少失败率。 关键词冠切断术，活髓切断术，根 保留
