A Comparison Between Clearing Technique And Cone Beam Computed Tomography For Detection Of Accessory Canals In Primary Molars: An In Vitro Study

Aim: Comparing Cone Beam Computed Tomography and clearing technique in human primary molars for detection of accessory canals. Materials and Methods: 100 extracted human primary molars constituting of maxillary and mandibular molars were collected. The study compared number of accessory canals using Cone Beam Computed Tomography and clearing technique in primary molars. The accessory canals were observed in furcation area; coronal one-third, middle one-third and apical one-third of root canals. Results: Although, the clearing technique showed more number of accessory canals as compared to CBCT technique, the difference was statistical significant insignificant. Conclusion: The clearing technique is nondestructive and more accurate but the main disadvantage of this method is that it cannot be used in vivo. Hence Cone Beam Computed Tomography which is clinically feasible can be considered over the clearing technique for detection of accessory canals.
