Abstract EN

Background & Objective: Few researchers have made a comprehensive study of the morphology of the root canals of the primary molars.

Thorough knowledge in internal anatomy of the primary molars is useful in reducing the problems of endodontic therapy arising due to the anatomical variation in root canals, which are clinically difficult to be detected.

Exploration the root canals of primary molars with regard to its number, variations, and accessory canals in the furcation region.

Materials & Methods: Clearing technique was used for 120 primary molars.

Results: most of the primary molars had 4 root canals, and some had 5 root canals.

Horizontal anastomosiss between root canals were common.

23% of molars had accessory canals in furcation area.

Conclusion: the complication of the internal anatomy of primary molars causing complication in endodontic treatment so the results of this study suggest avoiding pulpectomy in primary molars where ever possible.
