The purpose of this study was to compare the clinical and radiographic outcomes of fresh plant extract and mineral trioxide aggregate (MTA) as pulpotomy agents in primary molar teeth.
Pulpotomy procedure was performed in sixty primary molar teeth which were randomly allocated to two groups, i.e., pulpotomy (Group A) and MTA pulpotomy (Group B). All the pulpotomized teeth were evaluated clinically and radiographically at 1, 3, 6, 9, and 12 months of time interval using predetermined criteria.
The success rates between Groups A and B at the end of the 1 month were 24.1% and 96.4%, at the end of 3 month were 57.1% and 100%, at the end of 6 month were 75% and 100%, at the end of 9 month were 66.6% and 100%, and at the end of 12 months were 100% and 100% respectively. The overall success rates at the end of 12-month follow-up period were 6.9% and 71.4%, respectively, after taking dropout patients into consideration, and the difference was statistically significant ( < 0.001).
MTA pulpotomy was found to be superior when compared to fresh plant extract pulpotomy in primary molars.
本研究的目的是比较新鲜植物提取物和三氧化矿物凝聚体（MTA）作为乳牙牙髓切断术药物的临床和影像学结果。
对60颗乳牙进行牙髓切断术，随机分为两组，即牙髓切断术组（A组）和MTA牙髓切断术组（B组）。所有接受牙髓切断术的牙齿在1、3、6、9和12个月的时间间隔内，使用预定标准进行临床和影像学评估。
1个月结束时，A组和B组的成功率分别为24.1%和96.4%；3个月结束时分别为57.1%和100%；6个月结束时分别为75%和100%；9个月结束时分别为66.6%和100%；12个月结束时分别为100%和100%。在考虑失访患者后，12个月随访期结束时的总体成功率分别为6.9%和71.4%，差异具有统计学意义（<0.001）。
在乳牙中，MTA牙髓切断术比新鲜植物提取物牙髓切断术更具优势。
