部分活髓切断术和传统活髓切断术治疗年轻恒牙冠折露髓的临床效果(1)
[摘要] 目的 探讨部分活髓切断术与传统活髓切断术治疗年轻恒牙冠折露髓的临床效果。 方法 回顾分析我院在2011年7月～2014年7月收治的60例(68颗病牙)患有冠折露髓的年轻恒牙患者，随机均分为实验组和对照组，每组均30例(34颗病牙)。实验组采取Cvek方法的部分活髓切断术治疗，对照组采用传统常规活隋切断术治疗，比较两组临床疗效，术后2周、1、3、6个月定期观察患者的牙体疾病检查、牙髓活力测试、牙根发育状态、内外吸收和根管内钙化情况以及根尖病变情况等。 结果 实验组的成功率要高于对照组的成功率，分别为94.1%和88.2%，差异有统计学意义(P<0.05)；术后复查发现实验组的牙根发育等情况明显优于对照组，差异有统计学意义(P<0.05)。 结论 部分活髓切除术和传统活髓切断术均有效治愈冠折露髓年轻恒牙，前者的临床预后效果好，能促进牙根发育。

[Abstract] Objective To explore the clinical effect of partial pulpotomy and traditional pulpotomy in treating young permanent teeth crown pulp. Methods 60 young permanent teeth patients with exposed pulps in crown fracture (68 sick teeth) from July 2011 to July 2014 of our hospital were respectively analyzed.Patients were randomly divided into two groups experimental group and control group，and each group was 30 cases (34 sick teeth).Patients in experimental group were treated with partial pulpotomy of Cvek method，patients in control group was treated with traditional routine pulpotomy.The clinical effect was compared between two groups.Tooth disease examination，pulp vitality test，root development status of tooth，situation of inside and outside absorption and root canal calcification and pathological changes situation of root tip were routine observed 2 weeks，1 month，3 months and 6 months after operation. Results The success rate in experimental group was higher than that of control group，the success rate in experimental group and control group were respectively 94.1% and 88.2%，and the difference was statistical significance (P<0.05).It was found that root development status of tooth in experimental group was better than that of control group at postoperative reexamination，and the difference was statistical significance (P<0.05). Conclusion Both of partial pulpotomy and traditional pulpotomy can effectively cure the young permanent teeth with exposed pulps in crown fracture，but the clinical prognosis effect is good in the former and can promote the root development.
