A Study of Root Canal Morphology of Human Primary Molars Using Computerised Tomography: An in Vitro Study

J Indian Soc Pedod Prev Dent. 2005 Mar;23(1):7-12. doi: 10.4103/0970-4388.16019.


Knowledge of the size, morphology and variation of the root canals of primary teeth are useful in visualizing the pulp cavity during treatment. This study was carried out to investigate the applicability of Computed Tomography in studying the root canal morphology of the primary molars. A total of 60 primary molars.without any macroscopic root resorption were collected and divided into four groups. The samples were arranged in wax block and then scanned for evaluation in the CT Scanner both in axial and coronal plane. The results obtained from the scanned images were statistically analyzed to know the frequency, mean and standard deviation for all the groups. The images showed the complexity of the root canals of the primary molars and also several capabilities of the CT Scan in advance Endodontic research in primary teeth were observed.
