Accuracy of Mandibular Foramen Localization Using Digital Orthopantomogram (OPG) in Middle Eastern Population.

Background/objectives: Locating the mandibular foramen (MF) through imaging is clinically important for inferior alveolar nerve (IAN) anesthesia and mandibular ramus osteotomies. Although cone-beam computed tomography (CBCT) is superior in imaging the mandible, an orthopantomogram (OPG) is preferred for its ease of use and availability. Therefore, the present study aimed to evaluate the accuracy of digital OPG in localizing the MF, in a subset of the Middle Eastern population.

Cone-beam computed tomographic evaluation of root canal morphology of mandibular anterior teeth in a Saudi subpopulation, retrospective study.

Background: There is variability in the results of dental morphological studies between different ethnic populations. This study aimed to investigate the root canal morphology of mandibular anterior teeth in a Saudi subpopulation in the Riyadh region.

Methods: We examined a total of 1,769 cone-beam computed tomography (CBCT) images of the mandibular anterior teeth, including the central incisors (n = 587), lateral incisors (n = 590), and canines (n = 592).
