Middle mesial canal - A mystery in mandibular first molar: Report of two cases

IP Indian Journal of Conservative and Endodontics, 2023
Endodontic therapy aims at disinfection of the root canal system. Efforts are made by root canal instrumentation and chemical disinfection to remove the infected pulp tissue and debris from the root canal space. However due to variations in canal anatomy, it is impossible to instrument all the parts of canal and that may lead to persistence or ...

Deep learning cone‐beam computed tomography image segmentation for the 3D visualization of mandibular infraosseous periodontal defects

Journal of Periodontology, EarlyView.
Abstract Background The accurate assessment of infraosseous periodontal defects is crucial for effective diagnosis and treatment planning. Cone‐beam computed tomography (CBCT) enables detailed imaging of these defects; however, to leverage their full potential, CBCT images must be reconstructed in 3 dimensions (3D).

Frequency of Middle Mesial Canal in Mandibular Molars

Pakistan Journal of Health Sciences
Being the most difficult to detect unusual canal in mandibular molars, creating greater anatomical complexity and thereby variability, it is important that careful investigation aids in successful endodontic treatments. Objective: To evaluate the incidence and features of MMC in mandibular molars; to study demographic parameters and dental factors that
