  1. aOut of the 12 605 endodontically treated teeth, 11 956 teeth (94.8%) were treated using pulpectomy and 649 teeth (5.2%) were treated using pulpotomy method. Root filling length and homogeneity was measured only in pulpectomy group while coronal restoration was assessed in all endodontically treated teeth
