To observe the clinical effect of pulpotomy for cariously exposed permanent teeth with closed apices and provide guidance for clinical application.
Sixty-two cariously exposed permanent teeth with closed apices and vital pulps were included. Preoperative pulpal and periapical diagnosis was established. The teeth were divided into two groups, the experimental group was treated with pulpotomy(32 cases), and the control group was treated with one-visit root canal therapy (one-visit RCT) (30 cases). Clinical and radiographic evaluation was completed at 1 month, 3 months, 6 months, 12 months postoperatively. Statistical analysis was performed using SPSS 18.0 software package.
After 1 year, the success rate of pulpotomy was 93.75%, and the success rate of root canal therapy was 93.10%. There was no significant difference between pulpotomy and root canal therapy(P=0.665).
The advantages of pulpotomy are less invasive and less tooth destruction. It is a successful treatment option for cariously exposed pulps in mature permanent teeth.
观察活髓切断术治疗根尖孔未闭的龋源性露髓恒牙的临床效果，为临床应用提供指导。
纳入62颗根尖孔未闭且牙髓活力正常的龋源性露髓恒牙。术前进行牙髓及根尖周诊断。将患牙分为两组，试验组采用活髓切断术治疗（32例），对照组采用一次性根管治疗术（一次性根管充填）（30例）。术后1个月、3个月、6个月、12个月进行临床及影像学评估。采用SPSS 18.0软件包进行统计学分析。
1年后，活髓切断术的成功率为93.75%，根管治疗术的成功率为93.10%。活髓切断术与根管治疗术之间无显著差异（P = 0.665）。
活髓切断术的优点是侵入性小、对牙齿的破坏少。它是成熟恒牙龋源性露髓的一种成功治疗选择。
