Bilateral Mandibular Torus and an Ankylosed Third Molar: A Case Report

Abstract

Torus mandibularis is one of the types of exostosis in the oral region, which is unilaterally or bilaterally located in the lingual aspect of the body of the mandible above the mylohyoid line. The prevalence of tori has been estimated from 12.3% to 26.9% with an average age of onset typically in the fourth decade of life, and an increased prevalence in males. Although tori are known as an idiopathic condition, genetic and environmental factors, masticatory stress, and nutrition are the Abstract Environmental factors, genetic heritage, increased biting function and nutrition are some of the reason for intraoral exostosis to get developed. Torus mandibularis is one of the types of exostosis in the oral region, which is unilaterally or bilaterally located in the lingual aspect of the body of the mandible above the mylohyoid line. There is usually no need for biopsy for the diagnosis of tori. In symptomatic cases, excision is the treatment of choice. In this paper, a 65-year-old man with a wide bilateral mandibular torus and an ankylosed mandibular right third molar tooth with mucosal retention is presented and general information was given about tori. In relation with this case, it was thought that dental ankylosis and tori may occur together because of similar etiological factors.
