The aim of this study was to determine clinical and radiographic efficacy of the newly developed OrthoMTA and RetroMTA , compared frequently used ferric sulfate for pulpotomy in primary second molars.

A total of 96 second primary second molars from 32 children ,who met inclusion criteria and were 5-9 years old were selected for the study. Teeth were randomly divided into three groups according to the planned treatment: O-MTA (n=32 teeth), R-MTA (n=32 teeth) and FS (n=32 teeth). Clinical and radiographical follow-up examinations were conducted at 3, 6 and 9 months postoperatively. The data were evaluated with Chi-square test, Cochran Q test, Post-Huc Dunn test and Kaplan-Meier analysis.
