An Erupted Silent Tumour

Abstract

Odontomas are the most common odontogenic tumors of the oral cavity which are nonaggressive, hamartomatous in nature consisting of enamel, dentin and cementum. They are called as composite because they contain more than one type of tissue. They are generally asymptomatic, hence recognised on routine radiologic examination. The compound odontoma is composed of multiple small tooth like structures, whereas the complex odontoma consists of a conglomerate mass of enamel and dentine, which bears no anatomical similarity to the tooth. The eruption and infection of odontoma are uncommon, only few cases of erupted complex odontoma are reported in the literature. We report a case of silent erupting complex odontoma.

Tratamento E Análise Histopatológica De Odontoma Complexo: Relato De Caso

“…For Kudva et al (2016), odontomas may be seen in different stages of development. In the first stage, radiolucence is shown, due to lack of calcification.…”

“…Levi-Duque et al (2019) concluded that 63.3% of the cases were found in routine radiographic exams, 30% due to the lack of permanent tooth eruption, 5% due to infectious symptomatology and only 1.7% as a consequence of increase in volume. Therefore, it is consensual in the literature that in the majority of cases the odontomas are found in complementary exams, such as routine radiographs (KUDVA et al, 2016;MALTAGLIATI et al, 2020).…”

“…Among the possible differential diagnoses for complex odontoma are the ossifying cement fibroma, osteoíde odontoma, ameloblastic fibro-odontoma, cementoblastoma and the ameloblastic fibroma (MURPHY et al, 2014;KUDVA et al, 2016;ISOLA et al, 2017).…”

“…Paul Broca, in 1866, used the term odontoma to describe this tumor for the first time (ABDUL et al, 2014;SANTOS et al, 2016). 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 also denominated benign tumors of odontogenic origin (MURPHY et al, 2014;AKERZOUL et al, 2017;SPEIGHT;TAKATA, 2018;ELSAYED et al, 2020).…”

“…The odontoma generally affects the permanent teeth more than the primary teeth (ISOLA et al, 2017). They are intraosseous lesions more frequently found in the anterior region of the maxilla (compound) and posterior region of the mandible (complex), however, in the literature there has been a report of lesions localized in gingival soft tissues (ISOLA et al, 2017) or eruptions (MURPHY et al, 2014;KUDVA et al, 2016). They are commonly localized between the roots of erupted teeth or between the primary and permanent dentition (BEREKET et al, 2015).…”
