目的:分析活髓切断术对儿童恒前牙外伤冠折露髓的疗效情况。方法:2014年2月-2015年2月选择我院牙科收治的78例恒前牙外伤冠折露髓患儿,按照患儿入院顺序奇偶性将其分为观察组(n=39)及对照组(n=39),分别应用活髓切断术及根尖诱导成形术;术后,随访6-10个月,比较两组手术成功率及并发症发生率。结果:观察组手术成功率达95.35%,明显高于对照组81.82%(P<0.05)。观察组并发症发生率仅为2.56%,明显低于对照组15.38%(P<0.05)。结论:采用活髓切断术治疗恒前牙外伤冠折露髓患儿具有手术成功率高,并发症发生率低等优点,值得临床应用及推广。
Objective: To analyze the curative effect of vital pulpotomy on children with crown demyelination of traumatic crown injury. Methods: From February 2014 to February 2015, 78 children with permanent crown demyelination undergoing permanent dentition in our hospital were divided into observation group (n = 39) and control group (N = 39). The patients were treated with vital pulpotomy and apexoplasty respectively. After the operation, the patients were followed up for 6 to 10 months. The success rate and complication rate of the two groups were compared. Results: The success rate of operation in observation group was 95.35%, which was significantly higher than that in control group (81.82%, P <0.05). The complication rate in observation group was only 2.56%, which was significantly lower than that in control group (15.38%, P <0.05). Conclusion: The use of vital pulpotomy in the treatment of the anterior teeth traumatic crown demyelination has the advantages of high success rate and low complication rate, which is worthy of clinical application and promotion.
