Radiographic Predictors of the Mandibular Lateral Lingual Canal

210 participantsStarted 2026-08-04

Plain-language summary

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.

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.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
