对无法完成根管治疗的龋源性露髓恒磨牙行活髓保存治疗的效果观察 #br#

目的 观察对无法完成根管治疗的龋源性露髓恒磨牙行活髓保存治疗的临床效果。方法 选取30例无法完成根管治疗的龋源性露髓恒磨牙患者，经部分牙髓切断术（12 例）或冠髓切断术（18 例），应用生物陶瓷材料iRoot BP Plus行活髓保存治疗。术后定期随访，通过临床与影像学检查观察患牙治疗效果。结果 术后随访12~36个月，26例患牙未出现疼痛，牙根及根尖周正常，效果良好。2例患牙术后有冷刺激敏感，发展为急性牙髓炎；2例患牙复查时出现颊侧窦道，牙髓活力测试提示为死髓，患牙均予以拔除。结论 活髓保存治疗用于无法完成根管治疗龋源性露髓恒磨牙可取得较好的临床效果，且较根管治疗操作简单，治疗时间短。

The clinical effect of vital pulp preservation for carious exposed permanent molars unable tocomplete root canal therapy

Objective To observe the clinical effect of vital pulp therapy in permanent molars with cariously exposedpulp that can not complete root canal therapy.

The bioceramicmaterial iRoot BP Plus was used to preserve the pulp. The patients were followed up regularly after operation, and thetreatment effect was observed by clinical and imaging examination. Results After 12-36 month follow-up, 26 casesshowed a good clinical effect, no pain and the root and periapical were normal. Two cases had cold stimulation sensitivityafter operation and developed to acute pulpitis. Two cases had buccal sinus. The pulp vitality test showed that the pulp wasdead and the teeth were extracted. Conclusion The vital pulp therapy in permanent molar with cariously exposed pulp hasgood clinical effect. The operation of vital pulp therapy is easier and the treatment time was shorter than that of root canaltherapy.
