目的：比较三种牙髓切开术治疗磨牙18个月后的临床及影像学成功率。研究对象为51名5-9岁儿童的初生磨牙。这些牙齿被随机分为实验组和对照组。实验组去除冠状牙髓并止血后，剩余牙髓组织被生物牙定（A (R)）或矿物三氧化物聚集体覆盖。在对照组中，将甲醛甲酚与棉球一起放置在牙髓组织上5分钟，去除牙髓组织后用氧化锌-丁香酚（ZOE）膏体覆盖。所有牙齿立即用增强的ZOE基托和树脂改性玻璃离聚体水泥修复，然后用预成型的金属冠修复。随访评估分别在3、6、12和18个月后进行。18个月后，有45颗牙齿可供随访。所有可用的牙齿用于三氧化矿物聚集体和生物牙牙素（A (R)）的临床成功，73.3%的FC组。福尔甲酚组18个月的x线摄影成功率为73.3%，三氧化矿物集合体为100%，生物妥登（A (R)）组为86.6%。矿物三氧化物聚集体和生物辉石（A (R)）表现出比甲醛甲酚更有利的结果。
To compare the clinical and radiographic success rates of three different pulpotomy agents in primary molars after 18 months.The study was carried out with 51 primary molars of children aged 5-9 years old. The teeth were randomly assigned to the experimental or control groups. After coronal pulp removal and haemostasis, the remaining pulp tissue was covered with Biodentine(A (R)) or mineral trioxide aggregate in the experimental groups. In the control group, formocresol was placed with a cotton pellet over the pulp tissue for 5 min and after removal the pulp tissue was covered with zinc oxide-eugenol (ZOE) paste. All teeth were immediately restored with reinforced ZOE base and resin modified glass-ionomer cement, and later with pre-formed metal crowns. Follow-up assessments were carried out after 3, 6, 12 and 18 months.Forty-five teeth were available for follow up at the end of 18 months. All of the available teeth for mineral trioxide aggregate and Biodentine(A (R)) were clinically successful, as were 73.3% of the FC group. Radiographic success rate for the formocresol group at 18 months follow up was 73.3, 100% for mineral trioxide aggregate and 86.6% for Biodentine(A (R)) group.Mineral Trioxide aggregate and Biodentine(A (R)) showed more favourable results than formocresol.
