Evaluation of long-term results of two different calcium silicate based materials in primary molar teeth vital pulpotomies: An invivo study

Abstract

Objectives: Pulpotomy is one of the pulp therapy for cariously exposed pulps in primary molar teeth. There are several materials that allows regeneration of the residual pulp. The purpose of this study was to evaluate the efficacy of two different calcium silicate based materials (ProRoot MTA, BIOfactor MTA) in primary molar teeth vital pulpotomies. Materials and Methods: A total of 12 children (24 human mandibulary primary second molar teeth) aged between 6 and 9 years were selected in this randomized clinical study. The patients were randomly assigned to receive the pulpotomy medicaments. All pulpotomized teeth were restored with stainless steel crowns and evaluated clinically and radiologically at 1, 3, 6 and 12 months. Statistical analysis using chi-square test was performed to determine the significant differences between two materials. Results: Neither clinical nor radiographical differences were seen in 1st, 3rd and 6th months but in 12th month ProRoot MTA showed statistically better results in clinical evaluation (p=0.047). Conclusions: Both two calcium silicate based materials showed similar clinical and radiographical results by the end of 6th month but ProRoot MTA showed better results at the end of 12th month.
