Inclusion Criteria * Individuals aged 18 to 75 years. * Availability of previously acquired cone-beam computed tomography (CBCT) images obtained for diagnostic purposes. * Presence of a unilateral mandibular lateral lingual canal (MLLC) on CBCT images. * CBCT images of sufficient diagnostic quality to evaluate the location, diameter, and course of the MLLC. * Both mandibular sides included in the same CBCT examination, allowing comparison between the side with the MLLC and the contralateral side. * Absence of significant motion artifacts, metal artifacts, or reconstruction errors in the regions to be measured. Exclusion Criteria * CBCT images of insufficient quality for morphometric measurement or anatomical assessment. * Inability to clearly identify the mandibular canal, mental foramen, MLLC, or sublingual fossa boundaries. * Presence of bilateral mandibular lateral lingual canals. * History of surgery, trauma, fracture, resection, bone grafting, or implant placement in the mandibular region under evaluation. * Motion or metal artifacts that prevent reliable visualization or measurement of the anatomical structures. * History of systemic disease or syndrome affecting craniofacial or mandibular development. * Presence of cystic or tumoral lesions, exostoses, or other pathological changes affecting the region of interest. * History of orthodontic treatment affecting the region evaluated.
