Interradicular Canals in 213 Mandibular and 235 Maxillary Molars by Means of Micro-computed Tomographic Analysis: An Ex Vivo Study.

Introduction: Bacteria and/or toxin residuals in the furcation areas of mandibular and maxillary molars can be the cause of persistent periapical tissue inflammation before or after an endodontic treatment.

Methods: The objective of this ex vivo study was to investigate the frequency of interradicular canals and diverticula in first and second mandibular and first and second maxillary molars by means of micro-computed tomographic imaging. Five hundred thirteen extracted molars, 211 mandibular molars and 302 maxillary molars, were included in this investigation.
