Odontoma Composto-Complexo Associado à Cavidade Óssea Idiopática - Relato de Caso Clínico

Abstract

It is rare but possible to find two or more distinct lesions associated in the same patient. Of odontogenic tumors, odontoma is the most commonly encountered type. It is formed by an amorphous mass of dentin and enamel, which may contain pulp and cement and may or may not be associated with eruption of teeth. The idiopathic bone cavity is an intraosseous pseudocyst devoid of epithelial lining, consisting of an empty bone cavity or containing some fluid of unknown etiology. This lesion represents 1% of all maxillary cysts. The aim of this paper is to report an unusual clinical case of a composite-complex odontoma associated with an idiopathic bone cavity. Patient, male, 26 years old, was attended at the Stomatology Extension Clinic of UFU (PROCEDE - Program of Specific Care for Stomatological Diseases). At the clinical examination, an asymptomatic volume increase was observed; on the imaging examinations, a caliphate mass was observed with images that corresponded to two amorphous dental crowns and a radiolucent area that extended to a well defined delimited angle region of the mandible. Incisional biopsy was performed for refinement and aspiration puncture of the lesion, histopathological examination confirmed to be composite-complex odontoma and idiopathic bone cavity. The treatment was complete surgical removal of odontoma and curettage of the cavity. Conclusion: Follow-up with dental surgeon is essential for the discovery of clinically non-visible and asymptomatic lesions. It should also be noted that histopathological examination in the correct diagnosis of oral lesions is essential for a correct and effective treatment.
