摘要： 目的:采用回顾性研究,评估在全身麻醉下儿童牙病综合治疗中对深龋去腐净露髓的乳磨牙行三氧化矿物凝聚体(mineral trioxide aggregate,MTA)冠髓切断术后2年疗效。方法:收集2013~2015年在全身麻醉下因深龋去腐净后露髓而行MTA冠髓切断术的118颗乳磨牙临床资料,采用Zurn & Seale乳牙牙髓治疗后临床表现和影像学检查评分标准,评估其术后疗效。结果:牙髓切断术后6个月临床和影像学成功率均为99.1%;12个月时分别为98.1%和97.8%;18个月时分别为96.7%和94.5%;24个月时分别为94.3%和90.7%。并且,术后24个月时,牙本质桥的形成率为11%,根管闭锁的发生率为12.3%。结论:全身麻醉下对深龋去腐净露髓的乳磨牙行MTA冠髓切断术的远期疗效值得肯定,远期成功率较高,可以在临床广泛应用。

Abstract: Objective: To evaluate the clinical outcome of primary molars with cariously exposed vital pulps receiving mineral trioxide aggregate (MTA) as pulp-dressing agents in coronal pulpotomy under general anesthesia. Methods: The clinical and radiographic data of 118 primary molars were collected during 2013-2015. All teeth were restored with a glass ionomer cement base and stainless steel crowns after MTA coronal pulpotomy. Clinical and radiographic examinations were undertaken at the 1, 3, 6, 12, 18 and 24 months follow-up. Results: The clinical and radiographic success rates were both 99.1% at the 6-month recall visit. After 12 months, the clinical and radiographic success rates were 98.1% and 97.8%, respectively. After 18 months, they were 96.7% and 94.5%. At 24 months follow-up, they were 94.3% and 90.7%, respectively. As well, 11.0% primary molars were observed dentin bridge, and 12.3% exhibited pulp canal obliteration. Conclusion: The clinical effectiveness of coronal pulpotomy employing mineral trioxide aggregate on primary molars with deep caries under general anesthesia should be affirmed.
