Cone-beam computed Tomography: A Resolution to paradoxical Judgments in Endodontic Diagnosis

Recently, various diagnostic tools have emerged with a view to enhance endodontic treatment. Cone-beam computed tomography (CBCT) is presented as a new endodontic tool. The narrow field CBCT reduces the negative effects of anatomic noise, geometric distortion, and technique sensitivity observed on two-dimensional images. It can be used to identify canal morphology, numbers of canals, and relative positioning even in the presence of calcific metamorphosis (CM) and dystrophic calcifications. Calcific metamorphosis is characterized by the deposition of hard tissue within the pulp canal space. Most of the literature advices the treatment of CM through observation and periodic examination. Thus, it is imperative for the clinician to identify calcified canals preoperatively for conservative treatment approach. This case series illustrates about the versatility of CBCT over the conventional radiology for detecting calcified canals.
