Compound odontoma associated with an unerupted rotated and dilacerated maxillary central incisor

Abstract

Odontomas are benign tumors containing various component tissues of teeth. They usually remain asymptomatic and are diagnosed on routine radiographs. Clinically, they are often associated with delayed eruption or impaction of permanent teeth and retained primary teeth. A case of compound odontoma in association with an unerupted, rotated and dilacerated maxillary permanent right central incisor in a 12-year-old boy is reported. Such combination is rare, making it an interesting case for reporting. We have also discussed the clinical features, diagnosis and treatment of such a condition.

Odontoma: a retrospective study of 73 cases

“…The most common location was the anterior region of maxilla2,12,15 and the incisor lesion was diagnosed and treated earlier than the canine or third molar lesions 14. In the present study, the most common locations were, respectively, the canine region for the compound odontoma and the molar region for the complex odontoma, which corresponded with the reports of Kulkarni et al7 and da Costa et al16 Odontomas rarely involved the primary dentition (1.3-12.8%)2,15 and in the current study, none of the odontoma involved the primary dentition.…”

“…Many studies have reported various disturbances to tooth eruption related to odontomas 2,5-7,9,14,16,18,19. Katz14 studied 396 cases of odontomas in all age groups and found that 41% were associated with unerupted teeth.…”

“…There has been no general agreement on the best management approach for impacted teeth associated with odontomas. The treatment options comprise surgical extraction, and surgical opening and postsurgical clinical and radiological controls to evaluate the course of these teeth 3,7,9,17. Morning18 examined 42 cases of impacted teeth related to odontomas and reported that removal of the odontomas in the primary operation led to the eruption of the impacted teeth in 45% of cases, with a second surgical and/or orthodontic intervention giving better results.…”

“…Partial calcification is observed in the intermediate stage, while in the third stage the lesion usually appears as radiopaque masses surrounded by radiolucent areas corresponding to the connective tissue histologically 2,5. Odontomas are generally asymptomatic, often associated with delayed eruption, or impaction of permanent teeth 1-3,6,7,9-11. There have been many studies of odontomas dealing with clinical investigations, radiographic features,1,2,12-15 and case reports,5,7,8,16,17 however, these investigations included no results of treatments associated with the impacted permanent teeth according to age.…”

“…Foram descritos pela primeira vez por Paul Brocain em 1867 3 , e geralmente apresentam-se como uma massa anormal de tecido dentário calcificado, representando uma anormalidade com variáveis de tamanho e forma 1 . Dos tumores odontogênicos, é o que se apresenta com maior frequência nos maxilares e geralmente são encontrados em exame radiográfico de rotina, sendo caracterizado por seu crescimento lento, comportamento não agressivo e são diagnosticados entre a segunda e terceira décadas de vida 4,5 .…”
