Endodontic. Case Study Number 505146
A peculiar anatomical variation can be noticed on this mandibular first molar. What appeared to look like hypercementosis on apical aspect of distal root could in fact be a supernumerary root fused to the distal one (Radix Entomolaris). Careful removal of dentine with ultrasonic tips under high magnification of a dental operative microscope helped in locating this extra canal.
