摘要： 目的    研究Theracal LC（树脂改良性硅酸钙）在年轻恒牙牙髓切断术中应用的临床效果。方法    选择2017—2019年就诊于济宁口腔医院儿童口腔科7 ~ 11岁患儿因外伤冠折露髓的年轻恒牙87颗，随机分为Theracal LC组（44颗）和氢氧化钙组（43颗），分别使用Theracal LC和氢氧化钙作为牙髓切断术中的活髓保存剂，随访观察术后3、6、12个月两组疗效的差异。结果    本研究在随访期间共复查患牙82颗，其中Theracal LC组42颗，氢氧化钙组40颗。Theracal LC组有36颗患牙（85.71%）、氢氧化钙组有29颗患牙（72.50%）在术后3个月内形成牙本质桥，两组差异无统计学意义（χ2 = 2.17，P = 0.14）。术后6个月，Theracal LC组治疗成功率为97.62%，氢氧化钙组治疗成功率为87.50%，其差异无统计学意义（χ2 = 1.781，P = 0.182）；术后12个月，Theracal LC组治疗成功率（97.62%）高于氢氧化钙组（80.00%），差异有统计学意义（χ2 = 4.831，P = 0.028）。结论    Theracal LC在年轻恒牙牙髓切断术中应用的临床效果较氢氧化钙好，可在临床工作中推广使用。

Abstract: Objective    To explore the clinical effects of Theracal LC in pulpotomy of immature permanent teeth. Methods    The patients were chosen，who visited Jining Stomatological Hospital from 2017 to 2019，aged 7 - 11 years old. Totally 87 immature permanent teeth were selected which were pulp exposed by injure fracture. They were randomly divided into Theracal LC group（n = 44）and calcium hydroxide group（n = 43）. Theracal LC and calcium hydroxide were used as pulp preservation agents in pulpotomy. The difference in the curative effect between the two groups was observed at 3，6 and 12 months after operation. Results    During the follow-up period，82 teeth were reexamined. In Theracal LC group，42 were reexamined；in calcium hydroxide group，40 were reexamined. 85.71% of the Theracal LC group and 72.50% of the calcium hydroxide group formed dentine bridge within 3 months，the difference between two groups being not statistically significant（χ2 = 2.17，P = 0.14）；6 months after operation，the success rate of Theracal LC group was 97.62%，and that of calcium hydroxide group was 87.50%，the difference being not statistically significant（χ2 = 1.781，P = 0.182）；12 months after operation，the success rate of Theracal LC group was 97.62%，and calcium hydroxide group was 80.00%. There was significant difference between the two groups（χ2 = 4.831，P = 0.028）. Conclusion    The clinical effects of  Theracal LC in pulpotomy of immature permanent teeth is better than that of calcium hydroxide，which should be widely used in clinical practice.
