While the formocresol pulpotomy has enjoyed long-term clinical use and success, concerns over its toxicity and mutagenicity have prompted research into other pulpotomy techniques. The purpose of this study was to observe retrospectively the results of the electrosurgical pulpotomy technique used on primary molar teeth requiring pulp therapy, secondary to carious involvement. The mean age at the time of treatment was 5 years, 11 months and the mean postoperative observation time was 2 years, 3 months. Of the 164 teeth studied, 127 were normal at the last observation visit; 32 had undergone exfoliation; 4 had an abnormality associated with the pulpotomized tooth, but were not considered failures; and 1 was considered a failure. This is a 99.4 percent success rate. Compared to a formocresol pulpotomy study of similar design, the success rate for the electrosurgical pulpotomy procedure in this study is higher at the statistically significant level of p < 0.01.
尽管甲醛甲酚活髓切断术长期以来一直在临床中使用且取得了成功，但对其毒性和致突变性的担忧促使人们对其他活髓切断术技术展开研究。本研究的目的是回顾性观察对因龋坏而需要进行牙髓治疗的乳磨牙采用电外科活髓切断术的效果。治疗时的平均年龄为5岁11个月，术后平均观察时间为2年3个月。在研究的164颗牙齿中，最后一次观察时127颗正常；32颗已脱落；4颗与活髓切断术的牙齿相关出现异常，但不被视为失败；1颗被视为失败。成功率为99.4%。与一项设计类似的甲醛甲酚活髓切断术研究相比，本研究中电外科活髓切断术的成功率在p<0.01的统计学显著水平上更高。
