MORENO GARCIA, C. et al. Ectopic third molar of the maxillary sinus-infraorbital region. Rev Esp Cirug Oral y Maxilofac [online]. 2007, vol.29, n.3, pp.173-177. ISSN 2173-9161.

Introduction. Ectopic third molar teeth are those that are impacted in unusual positions, or that have been displaced and are at a distance from their normal anatomic location. Ectopic eruption of a tooth within the oral cavity is common, but rare in other sites. Ectopic eruption can be associated with developmental disturbances, pathologic processes or iatrogenic activity. Case Report. Female, fifty-six years old, with an upper right ectopic third molar located in the maxillary sinus-infraorbital region. She presented with pain and inflammation of the right side of her face that she had been experiencing for along time and which had been resistant to treatment. Surgical excision was carried out of the third molar tooth using the Caldwell-Luc approach. Discussion. In many cases the etiology of ectopic third molars cannot be identified. Generally they are asymptomatic and diagnosed by radiology studies. Conclusion. The indication for extraction in ectopic teeth cases is in general determined by the presence of symptomatology, or by the need for preventing future complications.
