AIM
The aim of this study is to evaluate and compare Biodentine and mineral trioxide aggregate (MTA) as pulpotomy agents by clinical and radiological assessments in primary teeth.
MATERIALS AND METHODS
In this study, 90 decayed primary molars indicated for pulpotomy were chosen and are divided into two groups. Soft enamel and dentinal caries were removed using spoon excavator. Access opening was done using highspeed cool water handpiece. Normal saline was used to irrigate pulp chamber, later saline moistened cotton pellet was used to obtain hemostasis in both groups. Restorations were placed in respective groups and immediate postoperative radiographs were taken. Follow-ups were done at every 3 months intervals, i.e., 3, 6, 9, and 12 months respectively.
RESULTS
Statistical evaluation was carried out by using paired t-test which showed no significant difference between the two groups (p ≥ 0.05) with high success rate of 95.5%.
CONCLUSION
Pulpotomy with MTA and Biodentine is a reliable biological method for pulp treatment of primary teeth.
CLINICAL SIGNIFICANCE
Mineral trioxide aggregate and Biodentine could be considered as a reliable biological method for pulp-otomy of primary teeth.
目的
本研究旨在通过对乳牙进行临床和影像学评估，来评价和比较生物活性玻璃粘固粉（Biodentine）和三氧化矿物凝聚体（MTA）作为牙髓切断术药物的效果。
材料与方法
本研究选取了90颗需要进行牙髓切断术的龋坏乳牙，并将其分为两组。使用挖匙去除软质釉质和牙本质龋。使用高速水冷手机开髓。两组均用生理盐水冲洗髓腔，随后用生理盐水浸湿的棉球止血。在各相应组放置修复体，并拍摄术后即刻X线片。每隔3个月进行随访，即分别在3、6、9和12个月时进行随访。
结果
采用配对t检验进行统计学评估，结果显示两组之间无显著差异（p≥0.05），成功率高达95.5%。
结论
使用MTA和生物活性玻璃粘固粉进行牙髓切断术是一种可靠的乳牙牙髓治疗生物学方法。
临床意义
三氧化矿物凝聚体和生物活性玻璃粘固粉可被视为乳牙牙髓切断术的可靠生物学方法。
