Abstract
Multiple maxillary and mandibular exostoses are common localized overgrowths of the bone. They are non-neoplastic and are thought to be reactive or developmental in origin. These exostoses need to be accurately distinguished from the other more diagnostically significant lesions, notably from the exosteal osteomas. The aetiology of exostosis has been investigated by different authors, but no consensus has been reached so far. We are reporting a rare case of an otherwise healthy 38 year old female with multiple exostoses in the mandibular anterior region, which correlated both clinically and radiographically.
