Retained teeth can be associated with a variety of diseases with mechanical, nervous, infectious, cystic and tumoral complications. The aim of this research is to report a case of concurrent dentigerous cyst and odontoma, associated with a retained upper canine. We present a 15-year-old patient who comes to the Maxillofacial Surgery Service from the Dental Faculty due to an evident volume increase in the vestibular surface of the maxillary alveolar ridge in 13 area, and progressive distal coronal displacement of 12. An interview, a clinical examination and a radiographic study were performed; tooth retention of 13 was observed, with association of defined rounded radiopaque area and circumscribed radiolucent area. A biopsy of the described tissues was performed and a diagnosis of dentigerous cyst and complex odontoma was obtained. The phenomenon of tooth retention appears concomitantly with other lesions that can produce bone destruction and disorder of position and number.

Palabras clave : tooth abnormalities; dentigerous cyst; anodontia.
