Extended compound odontoma in a pediatric patient: case report

Abstract

Introduction: Odontomas are odontogenic tumors, considered developmental hamartomas that often interfere with tooth eruption. Aims: to report the clinical case of compound odontoma in the posterior region of the jaw, from the radiographic finding to the surgical moment and diagnostic confirmation with histopathological examination. Case report: this is a female patient, 7 years old, white, referred from the Family Health Unit (FHU) to the outpatient clinic of the Oral and Maxillofacial Surgery and Traumatology Service of the Oswaldo Cruz University Hospital (OCUH), due to a radiopaque radiographic finding, with well-defined limits and a surrounding radiolucent halo, in the body of the jaw on the left side, between the roots of teeth 74 and 75. The proposed treatment was conservative surgical excision under general anesthesia. After removal of the lesion, multiple calcifications of different sizes and shapes were identified, resembling denticles, referred for histopathological examination and confirming the diagnosis of compound odontoma. After 7 days, a satisfactory healing process was observed. She will be followed up to analyze the progression of bone pocket repair and movement in permanent dentition in the region. Final considerations: Therefore, conservative surgical treatment is recommended, through the complete removal of the lesion and maximum preservation of retained teeth. For this identification at an early stage and proper treatment are essential.
