The mixed odontogenic odontomas are entities composed of a mixture of differentiated odontogenic epithelial and mesenchymal cells. The objective of this paper was to presente an unusual case of association of dental impaction caused by odontoma and altered dental formula. A male patient aged 26 years, who felt pain, attended the outpatient Oral and Maxillofacial Surgery service. The physical examination found facial asymmetry with facial hard elastic augmentation in the right facial lower third. The Intraoral physical examination showed persistence of oral 65^th and 85^th , clinical absence of 15^th , 47^th and 48^th with expansion of the vestibular and lingual cortices in the right posterior mandibular area (retromolar and molar regions) and presence of rounded mucosal opening about 8 mm distal to the 46^th , on top of the alveolar ridge. In the orthopantomographic study, a ± 3cm radiopaque image with irregular edges, associated with oligodontia of the 48^th and impaction of the 47^th , were observed. It was decided to surgically remove the lesion together with the 47^th and to indicate histopathological study. It was confirmed that the patient had a complex odontoma with peripheral soft tissue areas that showed chronic inflammation. The patient is still followed-up from the clinical and imaging viewpoints after three months of surgery.

Keywords : complex odontoma; odontogenic tumors; impacted teeth; altered dental formula.
