About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
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.
Disqualifiers
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.
Trial population
The study population will consist of adults aged 18 to 75 years with previously acquired diagnostic cone-beam computed tomography (CBCT) images archived in the Department of Oral and Maxillofacial Radiology at Recep Tayyip Erdoğan University Faculty of Dentistry. Only individuals with a unilateral mandibular lateral lingual canal (MLLC) identified on CBCT images and meeting the eligibility criteria will be included.

Trial outcomes
Primary outcomes
1
Mandibular Canal Diameter
Mandibular canal diameter will be measured in millimeters (mm) on coronal CBCT images at the level of the mandibular first molar furcation on both the side with the mandibular lateral lingual canal (MLLC) and the contralateral side. Higher values indicate a larger mandibular canal diameter.
Time frame
Baseline (retrospective CBCT assessment)Secondary outcomes
1
Mental Foramen Diameter
Mental foramen diameter will be measured in millimeters (mm) in the superoinferior direction on CBCT images on both sides. Higher values indicate a larger mental foramen diameter.
Time frame
Baseline (retrospective CBCT assessment)2
Sublingual Fossa Depth
Sublingual fossa depth will be measured in millimeters (mm) as the perpendicular distance from the deepest point of the sublingual fossa to a reference line connecting the superior and inferior borders of the lingual cortical surface. Higher values indicate a deeper sublingual fossa.
Time frame
Baseline (retrospective CBCT assessment)3
Mandibular Lateral Lingual Canal Diameter
The diameter of the mandibular lateral lingual canal (MLLC) foramen will be measured in millimeters (mm) on CBCT images. Higher values indicate a larger MLLC diameter.
Time frame
Baseline (retrospective CBCT assessment)4
Mandibular Lateral Lingual Canal Location
The anatomical location of the mandibular lateral lingual canal will be determined according to the tooth region through which the canal courses. The outcome will be reported as the frequency and percentage of canals identified in each anatomical location.
