This study aimed to review the literature on adult mandibular lingula (ML) locations and related distances determined using cone-beam computed tomography (CBCT). A search was conducted for studies on CBCT using the following databases: PubMed, Web of Science, and Embase. The search results were limited to studies published between 1970 and 2021. The inclusion criteria were the investigation of ML location, CBCT, and participants aged ≥18 years. Eligible studies were examined for the distances from the lingual tip to the anterior ramus border, posterior ramus border, sigmoid notch, inferior ramus border, and occlusal plane. Eight studies on CBCT qualified for inclusion in the study. The mean distances from the ML to the anterior ramus border were 15.57 to 20 mm. In most of these, the ML was located above the occlusal plane. No significant differences were observed in the location and related distances for the ML among patients of different sexes, ethnicities, or skeletal patterns.

“…This is primarily due to the low success rate of the anesthetic procedure, as previously mentioned, which was found to be approximately 29-35% [7]. Choi and Hur [58] claim that the maximal value from the occlusal plane can prevent injecting too deeply, thus preventing IAN block, in contrast to using the mean value as a point of reference. Nevertheless, preoperative scanning is a crucial step for the evaluation of the structure of the mandible prior to any invasive procedures [59].…”

“…Consequently, ML assumes a critical role in identifying this vital structure, necessitating routine identification during regular dental treatments and orthosurgeries. [1][2][3][4] The significance behind this lies in the functionality of the neurovascular bundle itself. As the inferior alveolar nerve (IAN) supplies sensory innervation to the lower teeth, administering an inferior alveolar nerve block (IANB) is a commonly employed technique to anaesthetise the lower teeth in everyday dental practice.…”

“…The mandibular lingula's (ML) positioning and localization have garnered significant attention due to its proximity to the mandibular foramen (MF), the entrance point for essential structures like the inferior alveolar neurovascular bundle within the mandible. Consequently, ML assumes a critical role in identifying this vital structure, necessitating routine identification during regular dental treatments and orthosurgeries 1–4 . The significance behind this lies in the functionality of the neurovascular bundle itself.…”

ObjectivesThis study aimed to evaluate the position of the mandibular lingula (ML) in adult patients (aged between 18 and 35 years old) with different skeletal and growth patterns using cone‐beam computed tomography (CBCT).DesignCross‐sectional.SettingDentistry department of University.SubjectsSubjects comprised CBCT images of 150 adult patients, including 300 rami.Methods and MaterialsIn total, 150 CBCT aged between 18 and 35 were selected and divided into three main groups of 50 samples based on their skeletal relationships (classes I, II and III). Patients were subdivided based on their growth pattern (vertical vs. horizontal), resulting in 25 samples per subgroup. Distances between the mandibular lingula and occlusal plane (ML‐OP), sigmoid notch (ML‐SN), external oblique ridge (ML‐EOR), internal oblique ridge (ML‐IOR), posterior border of the ramus (ML‐PBR), inferior border of the ramus (ML‐IBR), and horizontal and vertical distances to the mandibular foramen (ML‐hMF and ML‐vMF). One‐way ANOVA variance analysis was employed to compare different angle classifications, and Bonferroni analysis was used for multiple comparisons. The Student's t‐test was also used to compare growth patterns within each main group and genders within the subgroup.ResultsThe study revealed statistically significant differences in the position of the mandibular lingula between different angle classifications, growth patterns, and genders. Class II samples showed a more anterior position of the ML, whereas Class III samples displayed a more posterior position of the ML. Patients with horizontal growth patterns and Angle Class III had a more posteriorly positioned ML. Gender differences were observed, particularly in Class I and Class III classifications, suggesting that gender may influence the variability of ML position in these specific classifications.ConclusionThe position of the mandibular lingula showed high variability among individuals with different angle classifications, growth patterns and genders.
