These lesions are included in the spectrum of fibro-osseous lesions arising from periodontal ligament cells, which can deposit combination of cementum and bone surrounded by fibrous tissue. It clinically, macroscopically and radiologically resembles complex composite odontome and can be differentiated only on the basis of histopathology. They usually occur solitarily as a painless and expansile spherical or ovoid jawbone mass that may displace the roots of adjacent teeth. They predominantly occur in females in third and fourth decades of life. We present a case report of a 20-year-old man, with a mildly painful swelling in the mandible which was successfully treated with enucleation and diagnosed as COF. Its resemblance to complex composite odontome and unique surgical approach are highlighted in this paper.<\/jats:p>","DOI":"10.1136\/bcr-2016-216053","type":"journal-article","created":{"date-parts":[[2016,10,19]],"date-time":"2016-10-19T11:53:20Z","timestamp":1476878000000},"page":"bcr2016216053","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Cemento-ossifying fibroma of mandible mimicking complex composite odontome"],"prefix":"10.1136","volume":"2016","author":[{"given":"Hitesh Sudarshan","family":"Dewan","sequence":"first","affiliation":[{"name":"Oral and Maxillofacial Surgery, Faculty of Dental Sciences, Dharmsinh Desai University, Nadiad, Gujarat, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sudarshan Kumar","family":"Dewan","sequence":"additional","affiliation":[{"name":"Department of Oral and Maxillofacial Surgery, College of Dental Sciences and Research Centre, Ahmedabad, Gujarat, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sumit","family":"Bahl","sequence":"additional","affiliation":[{"name":"Department of Oral Pathology and Microbiology, Karnavati School of Dentistry, Gandhinagar, Gujarat, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Parth","family":"Tushar Parekh","sequence":"additional","affiliation":[{"name":"Private Practitioner, Ahmedabad, Gujarat, India"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,10,19]]},"reference":[{"key":"2025082800552106000_2016.oct19_2.bcr2016216053.1","first-page":"300","article-title":"Ossifying fibroma of the mandible\u2014case report and literature review","volume":"5","author":"Deliverska","year":"2016","journal-title":"Int J Sci Res"},{"key":"2025082800552106000_2016.oct19_2.bcr2016216053.2","first-page":"277","article-title":"Ossifying fibroma","volume-title":"Odontogenic tumours and allied lesions","volume":"32","year":"2004"},{"key":"2025082800552106000_2016.oct19_2.bcr2016216053.3","doi-asserted-by":"publisher","DOI":"10.1016\/0030-4220(94)90174-0"},{"key":"2025082800552106000_2016.oct19_2.bcr2016216053.4","unstructured":"Bone lesions.
