BACKGROUND/PURPOSE: Formocresol has been a popular pulpotomy medicament for primary molars, however, its toxicity and potential carcinogenicity leaves room for other alternatives such as sodium hypochlorite (NaOCl). The purpose of this study is to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.
MATERIALS AND METHODS
A retrospective research of patient records from January 1, 2009 and December 31, 2012 was conducted to evaluate the clinical and radiographic success rate of 5% NaOCl pulpotomy in primary molars.
RESULTS
A total of 147 NaOCl primary molar pulpotomies in 52 patients were included in the study. Clinical success rates at 6 months, 12 months, and 24 months were 100%, 97%, and 97%, respectively. Radiographic success rates at 6 months, 12 months, and 24 months were 99%, 89%, and 77%, respectively. Internal root resorption was the most common radiographic pathologic finding.
CONCLUSION
The clinical and radiographic success rate for NaOCl pulpotomies is comparable with formocresol and ferric sulfate pulpotomy success rates reported in previous studies.
背景/目的：甲醛甲酚一直是用于乳牙活髓切断术的常用药物，然而，其毒性和潜在致癌性为其他替代药物（如次氯酸钠（NaOCl））留出了空间。本研究的目的是评估5%次氯酸钠用于乳牙活髓切断术的临床和影像学成功率。
材料与方法
对2009年1月1日至2012年12月31日期间患者的病历进行回顾性研究，以评估5%次氯酸钠用于乳牙活髓切断术的临床和影像学成功率。
结果
本研究共纳入了52例患者的147颗接受次氯酸钠乳牙活髓切断术的牙齿。6个月、12个月和24个月时的临床成功率分别为100%、97%和97%。6个月、12个月和24个月时的影像学成功率分别为99%、89%和77%。牙根内吸收是最常见的影像学病理表现。
结论
次氯酸钠活髓切断术的临床和影像学成功率与先前研究报道的甲醛甲酚和硫酸铁活髓切断术的成功率相当。
