加州地区灵长类动物研究中心的意义 在上颌骨常规进行牙冠截断和重要的牙髓切断术 成年雄性(~7岁)恒河猴犬齿的排列 以减少对工作人员或笼友的自我伤害和伤害。失败者 据传闻，在中国，这一程序的比率很高。目标 牙冠切断术将与另一种方法进行比较 技术，包括从牙龈下切除牙冠和 缝合根部上的粘液膜瓣，露出重要的牙髓。 结果将在3点进行临床和放射学评估。 术后1个月和1年。结果牙冠切断术 对7只动物的上颌尖牙进行了牙髓切断术。 13只动物的牙龈下截肢。初步结果 表明后一过程的失败率高得令人无法接受， 这项技术将不会再被使用。恰如其分 采取了治疗措施来治疗受影响的动物。不是 到目前为止，在经历了皇冠的动物中注意到了失败 截骨术伴切牙术。未来的方向和长远的成果 牙冠切断术并改良这项技术 将故障率降至最低。牙冠切断术；牙髓切断术；牙根 保留

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
