INTRODUCTION
The aim of this study was to compare postoperative pain and success rate following pulpotomy and root canal treatment.
METHODOLOGY
Fifty-four permanent teeth with carious exposures were randomly divided equally into 2 groups. Mineral trioxide aggregate pulpotomy was performed in the experimental group and root canal treatment was performed in the control group, using standardized protocols. The treated teeth were restored with base of glass-ionomer cement followed by composite restoration. Pain was recorded every 24 hours for 7 days after intervention. Clinical and radiographic evaluations were done every 3 months for 18 months. The data collected were statistically analyzed.
RESULTS
At the end of follow-up, overall success rate was 85% in the pulpotomy group and 87.5% in the root canal treatment group (P > .05). Significant difference in pain incidence and pain reduction was found between the 2 groups (P < .05), with lower scores reported in the pulpotomy group.
CONCLUSION
Pulpotomy can be an alternative treatment for management of symptomatic permanent teeth with deep caries lesions.
简介
本研究旨在比较活髓切断术和根管治疗术后疼痛和成功率。
方法
将 54 颗有龋损暴露的恒牙随机均分为两组。实验组行矿化三氧化物凝聚体活髓切断术，对照组行根管治疗术，均采用标准化方案。用玻璃离子水门汀垫底后，复合树脂修复治疗后的牙齿。干预后每 24 小时记录疼痛一次，共 7 天。每 3 个月进行临床和放射学评估，共 18 个月。收集的数据进行统计学分析。
结果
随访结束时，活髓切断组的总成功率为 85%，根管治疗组为 87.5%（P>.05）。两组间疼痛发生率和疼痛缓解程度差异有统计学意义（P<.05），活髓切断组评分较低。
结论
活髓切断术可以作为治疗有症状的深龋恒牙的一种替代方法。
