The presence of buccal exostosis can be diagnosed by both clinical examination and radiological interpretation of the oral cavity. Clinically, buccal exostoses appear as single, broad-based masses, usually situated bilaterally in the premolar and molar region on the facial surface of the maxillary alveolar bone. [11]
Larger cysts may cause bone expansion or displace roots. Discoloration of the affected tooth may also occur. Patient will present negative results to electric and ice test of the affected tooth but will be sensitive to percussion. Surrounding gingival tissue may experience lymphadenopathy. The alveolar plate may exhibit crepitus when palpated.
A lump may be felt, which may feel hard if there is still bone covering the cyst, or fluctuant if the cyst has eroded through the bone surrounding it. [5] A cyst may become acutely infected, and discharge into the oral cavity via a sinus. Adjacent teeth may be loosened, tilted or even moved bodily. [6]
The long-term risk of coronectomy is that chronic infection can persist from the tooth remnants. The prognosis for the second molar is good following the wisdom teeth removal with the likelihood of bone loss after surgery increased when the extractions are completed in people who are 25 years of age or older.
Classic look of an odontogenic keratocyst of the right mandible in the place of a former wisdom tooth. Well defined, unilocular, radiolucent lesion within the bone. Diagnosis is usually radiological. However, definitive diagnosis is through biopsy. Aspirational biopsy of odontogenic keratocysts contains a greasy fluid which is pale in colour ...
Idiopathic osteosclerosis, also known as enostosis or dense bone island, is a condition which may be found around the roots of a tooth, usually a premolar or molar. [2] It is usually painless and found during routine radiographs as an amorphous radiopaque (light) area around a tooth.
Impacted wisdom teeth are classified by the direction and depth of impaction, the amount of available space for tooth eruption and the amount of soft tissue or bone that covers them. The classification structure allows clinicians to estimate the probabilities of impaction, infections and complications associated with wisdom teeth removal. [31]
Exostoses are sometimes shaped like spurs, such as calcaneal spurs. Osteomyelitis , a bone infection, may leave the adjacent bone with exostosis formation. Charcot foot , the neuropathic breakdown of the feet seen primarily in diabetics , can also leave bone spurs that may then become symptomatic.
