A well-preserved skull of a male Pan troglodytes troglodyte chimpanzee was scanned using a cone-beam computed tomography machine. Measurements included tooth and crown height, root length, root canal length and width (posterior teeth), and pulp cavity length (anterior teeth). Nonmetrical parameters included number of canals and foramina per root of every root. Interestingly, the mandibular central incisor was longer than the lateral incisor, and all the mandibular anterior teeth presented with a solitary flame-shaped or conical-calcified structure in their pulp cavity. The premolars are usually dual rooted except for the first maxillary premolar that displayed 3 roots. Other unusual discoveries were the presence of bilateral radicular dens invaginatus in the mandibular first premolars and the possibility of having 2 canals and 2 foramina in the roots of the posterior teeth. The presence of conical stone mineralizations at the pulp cavity and the presence of dens invaginatus were of particular interest.<\/jats:p>","DOI":"10.1177\/0898756418776448","type":"journal-article","created":{"date-parts":[[2018,6,5]],"date-time":"2018-06-05T00:58:08Z","timestamp":1528160288000},"page":"96-102","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Unusual Dental Morphology in a Chimpanzee: A Case Report Utilizing Cone-Beam Computed Tomography"],"prefix":"10.1177","volume":"35","author":[{"given":"Samah M.","family":"Al-Amery","sequence":"first","affiliation":[{"name":"Faculty of Dentistry, Department of Oro-Maxillofacial Surgical and Medical Sciences, University of Malaya, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Phrabhakaran","family":"Nambiar","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Department of Oro-Maxillofacial Surgical and Medical Sciences, University of Malaya, Kuala Lumpur, Malaysia"},{"name":"Faculty of Dentistry, MAHSA University, Saujana Putra, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob","family":"John","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Department of Restorative Dentistry, University of Malaya, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathiravan","family":"Purmal","sequence":"additional","affiliation":[{"name":"Klinik Pergigian Katte, Pandanjaya, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei Cheong","family":"Ngeow","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Department of Oro-Maxillofacial Surgical and Medical Sciences, University of Malaya, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nor Himazian","family":"Mohamed","sequence":"additional","affiliation":[{"name":"Faculty of Dentistry, Department of Restorative Dentistry, University of Malaya, Kuala Lumpur, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Subramaniam","family":"Vellayan","sequence":"additional","affiliation":[{"name":"Faculty of Pharmacy, Universiti Teknologi MARA, Puncak Alam, Kuala Selangor, Selangor, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2018,6,4]]},"reference":[{"key":"bibr1-0898756418776448","doi-asserted-by":"publisher","DOI":"10.2307\/3504299"},{"key":"bibr2-0898756418776448","doi-asserted-by":"crossref","DOI":"10.56021\/9780801857898","volume-title":"Walker\u2019s Mammals of the World","author":"Nowak RM","year":"1999","edition":"6"},{"key":"bibr3-0898756418776448","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhevol.2011.10.004"},{"key":"bibr4-0898756418776448","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhevol.2010.06.011"},{"key":"bibr5-0898756418776448","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0402635101"},{"key":"bibr6-0898756418776448","doi-asserted-by":"publisher","DOI":"10.1016\/j.jhevol.2006.09.004"},{"key":"bibr7-0898756418776448","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4020-5845-5_12"},{"key":"bibr8-0898756418776448","unstructured":"Napier JR, Napier PH.
