ABSTRACT
Pulpotomy is one of the most common treatments in decayed primary teeth with pulp involvement. So far various medicaments have been used for this procedure. The aim of this study was to compare the success and/or failure level of these materials by using clinical and radiographic measures. A total of 70 deciduous molar teeth of children aged 3-7 years-old who met our selection criteria were included in this randomized clinical trial. After pulpotomy the Iranian made and the original brand MTA was used. Amalgam was used for restoration of all teeth under investigation. The clinical and radiographic follow up was conducted blindly at 6 and12 months. Fisher's exact test was used for data analysis. Based on the information collected over of one year follow up period, none of the teeth in Iranian MTA group demonstrated clinical and radiographic failure. In the original MTA group 1 tooth developed abscess and another showed furcation radiolucency. Based on these results the Iranian brand mineral trioxide aggregate can be used in primary molar teeth for pulpotomy treatment
