Morphometric observations on root canals of human anterior teeth

Abstract

The theoretical possibility of using a standardized endodontic preparation and obturation technique in anterior teeth was investigated by measuring the widths of the roots and root canals of 100 teeth. Providing the canals were not too curved, circular-shaped preparations might be made with acceptable frequency in the apical 5 mm of maxillary central incisors and canines, and in the apical 3mm of mandibular canines. A circular canal might be prepared in maxillary lateral incisors and mandibular incisors only at the 1-mm level from th apex.
