Abstract

AIM

The aim of the present study was to clinically and radiographically evaluate Mineral Trioxide Aggregate (MTA) as an agent for pulpotomy in primary teeth and to compare it with that of Formocresol (FC) pulpotomy.

METHOD

Seventy first and second primary mandibular molars of children were chosen on patients who required minimum two pulpotomies in either arch or same arch. After the standardized technique of Pulpotomy with MTA and Formocresol, all molars were treated with a thick mix of Zinc oxide Eugenol cement into the coronal pulp chamber followed by preformed stainless steel crown. The children were followed up for clinical and radio graphical examination after 6, 12 and 24 month for Pain, Swelling, Sinus/fistula, Periapical changes, Furcation radiolucency and internal resorption.

RESULTS

MTA represents 97% clinical success rate in comparison to Formocresol with 85% success. Radiographically also MTA showed more promising results with 88.6% success in comparison to Formocresol with 54.3%.

CONCLUSIONS

Thus, MTA pulpotomy has emerged as an easier line of treatment to save the premature loss of primary teeth due to caries or trauma.

摘要

目的

本研究旨在从临床和影像学方面评估三氧化矿物凝聚体（MTA）作为乳牙牙髓切断术用药的效果，并将其与甲醛甲酚（FC）牙髓切断术进行比较。

方法

选取需要在任一牙弓或同一牙弓进行至少两次牙髓切断术的儿童的70颗下颌第一和第二乳磨牙。采用MTA和甲醛甲酚进行标准化牙髓切断术技术操作后，所有磨牙均用氧化锌丁香酚水门汀稠糊剂充填至冠髓腔，随后安装预成不锈钢冠。在6个月、12个月和24个月后对患儿进行随访，进行临床和影像学检查，观察疼痛、肿胀、窦道/瘘管、根尖周变化、根分叉透射区和内部吸收情况。
