年轻恒磨牙龋源性露髓部分活髓切断的临床研究

目的：应用氢氧化钙对年轻恒磨牙龋源性露髓行部分活髓切断术，并评价临床效果。方法：对48颗因龋露髓的年轻恒磨牙行直接盖髓术和部分活髓切断术，随访18个月，通过临床检查和X线检查比较两组疗效。结果：26颗年轻恒磨牙龋源性露髓行部分活髓切断，成功24颗，成功率92．3％。22颗行直接盖髓术成功17颗，成功率77．3％。结论：部分活髓切断术是治疗因龋露髓年轻恒磨牙有效的方法，同时，氢氧化钙是较为理想的盖髓剂。

The Clinical Observation on Vital Pulpotomy in Young Permanent Molar Teeth

Objective：To explore the clinical efficacy of partial vital pulpotomy for pulp exposure of in-completely developed young permanent molars due to caries with Ca （ OH） 2 .Method：48 young permanent molar teeth underwent direct pulp capping and partial vital pulpotomy .All of them were followed up for 18 months, and then evaluated the effect with clinical symptom and X-ray examination result .Result：24 in 26 young permanent molar teeth underwent partial vital pulpotomy successfully , the success rate was 92.3%.17 in 22 young permanent molar teeth underwent direct pulp capping successfully , the success rate was 77.3%. Conclusion：It＇s an effective method to treat young permanent molar teeth due to caries with partial vital pul-potomy, Ca（ OH） 2 is the ideal pulp capping agent .
