Abstract

Odontoma is a benign calcifying odontogenic tumor of unknown etiology, although local trauma, genetic factors, and chronic inflammation may be related. They are classified into compound and complex types, depending on the morphological, radiographic and histological characteristics. Clinically they hardly show signs or symptoms, and, when present, are related to delayed tooth eruption, cortical bone expansion and tooth displacement. Although radiographic exams are complementary, most cases of odontomas reported in the literature are found on routine radiographs. The diagnostic hypothesis is confirmed by histopathological examination that shows evidence of the presence of enamel, dentin, cementum and pulp tissue arranged in the form of denticles (compound) or a disorganized mass (complex). The treatment consists of surgical excision of the lesion. The aim of this article was to report a clinical case and histopathological analysis of a complex odontoma associated with an unerupted tooth, located on the left side in the posterior region of the maxilla, discovered by routine radiographic examination of a 57-year-old male patient. The treatment was surgical excision of the lesion, removal of the unerupted tooth and histopathological examination, which confirmed the diagnosis of complex odontoma. The case was followed-up clinically and radiographically for one year and showed no recurrence.

Highlights

Odontogenic tumors are rare findings in Dentistry
Odontomas are commonly found in the oral cavity (ABDUL et al, 2014; BEREKET et al, 2015; SANTOS et al, 2016; ISOLA et al, 2017) and account for 22% of odontogenic tumors found (ABDUL et al, 2014)
Paul Broca, in 1866, used the term odontoma to describe this tumor for the first time (ABDUL et al, 2014; SANTOS et al, 2016)

Summary

INTRODUCTION

Odontogenic tumors are rare findings in Dentistry. In the literature, their incidence is considered low, and ranges from 0.002% to 0.1% (TROELTZSCH et al, 2012). Due to the abnormal and disorganized development of the epithelial and mesenchymal cells (ABDUL et al, 2014; ISOLA et al, 2017), that give rise to the enamel, dentin, cement and pulp tissue, odontomas are considered developmental anomalies of the hamartoma type (KÄMMERER et al, 2016; ISOLA et al, 2017) and not true neoplasms (BOFFANO et al, 2012; ABDUL et al, 2014; KUDVA et al, 2016; AKERZOUL et al, 2017; MALTAGLIATI et al, 2020) They are denominated benign tumors of odontogenic origin (MURPHY et al, 2014; AKERZOUL et al, 2017; SPEIGHT; TAKATA, 2018; ELSAYED et al, 2020). The aim of this article was to report the treatment of a complex odontoma in the posterior region of the left side of the maxilla, associated with an impacted third molar, and its histopathological analysis
