Radiographic Predictors of the Mandibular Lateral Lingual Canal
Starting soon
Conditions studied: Mandibular Canal Visibility, MANDIBLE, CBCT Segmentation
In brief
The purpose of this retrospective observational study is to investigate whether mandibular canal dimensions and sublingual fossa morphology can serve as radiographic predictors of the mandibular lateral lingual canal (MLLC) using cone-beam computed tomography (CBCT). CBCT images of adults with unilateral MLLC will be retrospectively evaluated. Mandibular canal diameter, mental foramen diameter, and sublingual fossa depth will be compared between the side with the MLLC and the contralateral side. In addition, the location, diameter, and course of the MLLC will be analyzed to identify radiographic features associated with its presence and to improve preoperative assessment for mandibular surgical procedures.

Who can join
Age: 18 and older, up to 75. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- 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.
You may not qualify if…
- 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.
