Root canal morphology of human primary maxillary molars in Indian population using spiral computed tomography scan: An in vitro study

Abstract

Aim: The aim of the study was to evaluate the root canal morphology of primary maxillary molars in Indian population using spiral computed tomography (SCT). Materials and Methods: The 30 extracted primary maxillary molars were collected. The teeth were scanned using SCT. The scanned data was then transferred to image analysis software and evaluated for the following: Distance between the central fissure to furcation, distance between the central fissure to the floor of the pulp chamber, height of the pulp chamber (roof-floor), distance between the floor of the pulp chamber to the furcation and number of canals. Results: The results of this study shows that the average mean distance from the central fissure to the floor of the pulp chamber is 5.02 mm and 5.32 mm in first maxillary primary molar and second maxillary primary molar. Conclusion: Knowledge of the root canal morphology and anatomical landmarks of the primary maxillary molar might be a very helpful indicator to the dentist during access opening.
