“…Our study investigated the presence and characteristics of LF and its associated anatomical structures in a sample of 650 cases. The study found that LF was observed in all the cases, which aligns with previous research conducted,[ 2 9 12 13 ] which reported a 100% prevalence. However, these results contrasted with findings from earlier studies,[ 14 15 ] which reported lower prevalence rates, ranging from 58.8% to 93.3%.…”

Background: Surgical procedures in the anterior mandibular region require a profound understanding of the complex anatomical structures to ensure patient safety. The lingual foramen (LF) and its intra-osseous canal are pivotal structures, supplying vascular and neural support to the mental region. The prevalence of LF is widely recognized, with variations among populations. Methods: The study involved 650 adult participants. Data were collected using high-resolution cone-beam computed tomography (CBCT), and statistical analysis was conducted, establishing inter-rater agreement. Results: The population had a varied age distribution, with males comprising 53.23% and females comprising 46.77%. The median lingual canal was found in the Supra and Infra spinosum (65.38%). Most participants had lateral lingual canals (60.92%). The most prevalent lingual foramina was 4 (30.62%). The study found no significant associations between gender and LF diameter, distribution in different travel directions, or LF locations. However, males had a slightly larger diameter. Conclusion: The findings provide valuable insights into LF variations based on anatomical locations, and there were no statistically significant differences in measurements across different age groups. This knowledge contributes to the evolving field of oral and maxillofacial surgery, ensuring better patient outcomes.

“…The anterior mandibular area between two foramina has been proved to have rich arterial anastomoses and a high rate of anatomical variations. 1 Moreover, a close relationship between the cortical bones and the arteries responsible for blood supply as well as the shallow and narrow bone structure caused by resorption of the alveolar crest following tooth loss have been shown to limit the therapeutic choices in this region. Moreover, the natural lingual concavity of the alveolar crest that remains in the form of a blade ridge because of resorption brings about risks of perforation and bleeding during and/or after implant operations.…”

“…Even though the anterior mandible is regarded as a safe region for implant and/or graft operations in terms of easy access to the surgical site, lately, it has been recently shown to have a variety of disadvantages. The anterior mandibular area between two foramina has been proved to have rich arterial anastomoses and a high rate of anatomical variations 1 . Moreover, a close relationship between the cortical bones and the arteries responsible for blood supply as well as the shallow and narrow bone structure caused by resorption of the alveolar crest following tooth loss have been shown to limit the therapeutic choices in this region.…”

AimTo compare the linear and angular measurements of the mandibular symphyseal region using lateral cephalometric (LC) and cone beam computed tomography (CBCT) images.Materials and MethodsOne hundred patients justifying both LC and CBCT exposures were included. Both lateral cephalometric and CBCT images of the patients were used for angular and linear measurements. Angular measurements included vestibular concavity and lingual and tooth inclination angles. Vestibular and lingual cortical bone and total bone thickness measurements were obtained for the comparison of linear measurements. Three radiologists performed the measurements on 200 images. Comparison of the measurements and the imaging methods were done using paired‐ and Wilcoxon t‐tests. Inter‐observer reliability was evaluated with the intra‐class correlation coefficient (ICC).ResultsA significant difference was observed between measurements of two imaging methods for tooth inclination and vestibular concavity angles; however, no difference was found between LC and CBCT measurements for lingual inclination angle (p > 0.05). Vestibular cortical bone and total bone thickness measurements showed a significant difference (p < 0.05), whereas no difference was obtained in lingual bone thickness measurements of two imaging methods (p > 0.05).ConclusionCBCT imaging is recommended in selected patients where recipient bone or bone augmentation site(s) reveal suspect in clinical examination and lateral cephalometric imaging may not reveal the true anatomic structure and relationships.
