Abstract

Objectives

The aim of the study was to investigate the course and anatomy of the lingual nerve (LN) to minimize the risk of iatrogenic damage during dental procedures.

Material and Methods

The LN was dissected in 25 cadavers (dentulous and edentulous). The intersection of the LN and submandibular duct (SMD), the bifurcation location from the mandibular nerve, the branching patterns of the main trunk, and the number of terminal branches were recorded.

Results

In dentulous females, LN distances to the third, second, and first molars were 11.46 ± 2.51, 15.50 ± 5.24, and 18.75 ± 5.91 mm, while in dentulous males, they were 10.98 ± 1.27, 15.75 ± 2.61, and 19.65 ± 4.50 mm, respectively. For edentulous mandibles, all distances were shorter compared to the dentulous group. In 39.13%, the LN passed superior to the SMD. The LN is bifurcated above the mandibular notch in all cases. The number of branches entering the tongue ranged from 2 to 9, with a Type 1 branching pattern found to be the most prevalent.

Conclusions

The study incorporated both dentulous and edentulous cadavers from a South African population. The findings hold significance for surgical procedures, providing valuable insights into minimizing potential damage.

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
