ABSTRACT
Objective: to compare the clinical and radiographic success rate of" Biodentine" to that of “mineral trioxide aggregates" (MTA) when used as “pulpotomy agents" in primary molars of children. Study design: This split-mouth controlled randomized clinical study was performed on 10 healthy children age ranged from 2-6 years indicated for complete oral rehabilitation under general anaesthesia, with at least two carious primary molar indicated for pulpotomy. A total of thirty primary molars were treated, teeth were randomly assigned into two groups: Group A “Biodentine" group and Group B “MTA" group. All teeth were restored with “stainless steel crowns". Follow up was done after 6 and 12 months for clinical and radiographic assessment. Results: clinical success rate was 100% in both group after12 months follow up period. Both groups showed internal root resorption (IRR) either at 6 or 12 months follow up. In the “Biodentine" group four teeth out of 15 showed internal root resorption (IRR) in the whole period of the study. In the “MTA" group two teeth showed IRR in the whole period of study. The radiographic success rate of Biodentine to MTA was 73.3% and 86.6% respectively, with no statistically significant difference between the two groups (P=0.65). Conclusion: Using “Biodentine" and “MTA" as pulpotomy agent in primary teeth showed excellent clinical results. Radiographically, IRR was a finding in both groups. “Biodentine" showed more number of teeth with IRR but the difference was not statistically significant.
