Buccal-sided mandibular angle exostosis - A rare case report

Abstract

Buccal exostoses are benign, broad-based surface masses of the outer or facial aspect of the maxilla and less commonly, the mandible. They begin to develop in early adulthood and may very slowly enlarge over the years. They are painless and self-limiting, but occasionally may become several centimeters across and then contribute to periodontal disease of the adjacent teeth by forcing food during chewing in toward the teeth instead of away from them, as is normally the case. The following paper presents a very rare case of buccal-sided mandibular angle exoxtosis and its management with surgical exploration.

Multiple Mandibular Tori: Three Case Reports And Review.

“…[17] In our cases one patient has generalized attrition which seconded that the occlusal stress as one of the etiological factor for TM.Studies done by Shubha Rajan Dutta et al [15] found that , TM arises on the lingual side of the jaw, in the region of the Premolars or bicuspids generally above the location of the mylohyoid muscles attachment to the mandible and may extend to molar region. Similar findings were seen in our cases also, the tori were extended from lateral incisors to molars According to Salman Basha et al [9] and Shubha Rajan Dutta et al [15] TM generally manifested bilaterally, forming hard ,rounded swelling. Similarly, in our cases they are also found bilaterally.…”

“…According to Salman Basha et al [9] the torus may be bosselated or multilobulated. Manasi bansal et al [18] and Youna Choi et al [16] have shown that Tori consists of prominent hard tissue with a thin mucosa and it has a normal appearance .But traumatic ulcers may easily develop at the site if it is exposed to trauma and then it may become whitish and ulcerative. In all the 3 cases mentioned , there was no history of trauma or ulceration and mucosa was absolutely normal with no lymphdinopathy.…”

“…According to Salman Basha et al [9] TM is recognized as a bony ridge or series of bony nodules or lumps appearing on the lingual surface of the alveolar margin of the mandible, generally in the premolar region. In our cases we also found the tori in premolar region.…”

“…The exact cause of appearance is not clear [1,2,6,8,9]. The most accepted theory of TM today is of genetic origin in 29.5% cases and 70% cases are related to increased masticatory forces to the teeth i.e.…”

“…[2,8]Another cause is superficial injuries or its occurrence as a functional response in individuals with well developed chewing muscles.or in patients with abraded teeth due to occlusion Reichart et.al. [10],Andres S. Garcia et al [1] and Basha S. et al [9] found a significant co-relation between the incidence of Torus and the presence of abraded teeth. Cliford et.al.…”
