[摘要] 目的：探讨硫酸铁溶液作为儿童磨牙牙髓切断术药物的可行性。方法：选择3~5岁儿童的第一乳磨牙、4~6岁儿童的第二乳磨牙共45人，80颗乳磨牙深龋近髓的病例，随机分为两组，分别行甲醛甲酚(FC)和硫酸铁溶液牙髓切断，术后6个月及1年复查，分别统计两组成功率，比较两组的疗效差异。结果：FC组和硫酸铁溶液组6月及1年的成功率无显著性差异(P>0.05)。结论：从临床疗效看硫酸铁溶液是一种较好的牙髓切断药物。

    [Abstract]Objective: To assess the feasibility of ferric sulfate as a pulpotomy agent in primary teeth.Methods: 80 primary molars with deep caries close to the pulps were selected. They were divided into two groups, and operated pulpotomy using formocresol (FC) and ferric sulfate respectively. The children were followed up after 6 months and 1 year. Successful rates of pulpotomy were summarized statistically. Results: Successful rates of pulpotomy after 6 months and 1 year between FC group and ferric sulfate group showed no significant difference (P>0.05). Conclusion: Observed from clinical efficiency, ferric sulfate is a good pulpotomy agent. ......
