Complete intraoral and extraoral clinical examination was done. Routine radiographical investigations were advised. Based on clinical and radiographical findings she was provisionally diagnosed with odontoma of left mandible. It was a considerably giant mass with thinned out both cortical plates and the inferior border of the mandible. Although we assumed high risk of fracture of the mandible, successful surgical excision of the tumour was done using a minimally invasive intraoral approach and by sectioning the odontoma, sparing cortical bones. We managed to remove the whole of tumour without fracturing the mandible. Final histopathological report confirmed the initial diagnosis of complex composite odontoma. Patient is under regular follow-up.<\/jats:p>","DOI":"10.1136\/bcr-2023-254948","type":"journal-article","created":{"date-parts":[[2023,5,5]],"date-time":"2023-05-05T10:16:40Z","timestamp":1683281800000},"page":"e254948","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":7,"title":["Huge complex composite odontoma of mandible"],"prefix":"10.1136","volume":"16","author":[{"given":"Hari","family":"Ram","sequence":"first","affiliation":[{"name":"Oral and Maxillofacial Surgery, King George Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ezhilarasi","family":"Sundaram","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, King George Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ravi","family":"Katrolia","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, King George Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richa","family":"Gupta","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, King George Medical University, Lucknow, Uttar Pradesh, India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,5,5]]},"reference":[{"key":"2025082712302782000_16.5.e254948.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.coms.2004.03.005"},{"key":"2025082712302782000_16.5.e254948.2","doi-asserted-by":"crossref","first-page":"68","DOI":"10.1007\/s12105-017-0794-1","article-title":"Update from the 4th edition of the World Health Organization classification of head and neck tumours: odontogenic and maxillofacial bone tumors","volume":"11","author":"Wright","year":"2017","journal-title":"Head Neck Pathol"},{"key":"2025082712302782000_16.5.e254948.3","first-page":"309","article-title":"Odontome: a breif overview","volume":"78","author":"Hitchin","year":"1958","journal-title":"Dent Rec"},{"key":"2025082712302782000_16.5.e254948.4","doi-asserted-by":"crossref","first-page":"177","DOI":"10.5005\/jp-journals-10005-1106","article-title":"Odontome: a brief overview","volume":"4","author":"Satish","year":"2011","journal-title":"Int J Clin Pediatr Dent"},{"key":"2025082712302782000_16.5.e254948.5","unstructured":"Andreasen JO , Andreasen FM .
