Complex-Compound Odontoma: A Rare Clinical Presentation

Abstract

Odontomas can be detected as complex or compound variants and they rarely show the histologic characteristics of both types together. The tumor commonly associated with malocclusion, eruption disturbances and pathological anomalies, but they seldom cause bony expansion. Early detection and management of odontoma with multidisciplinary approach pose an important role to prevent disturbances associated with this common odontogenic tumor. Here we report a rare case of an odontoma which show the features of both complex and compound types and also cause bony expansion, eruption failure in an 8-year-old boy.

Complex Compound Odontoma Associated with an Unerupted Tooth: A Rare Entity

“…[4,13] Keskin et al, found only five reports (4 case report and 1 retrospective study) about complex-compound odontoma in the literature. [14] Thus, the present case is unique as it has combined features of both compound and complex odontoma. In a review of 160 cases of odontomas by Tekkesin et al, of all the investigated cases, 99 were complex, 57 were compound, and only four were mixed odontomas.…”

Odontoma composto em região anterior de mandíbula

“…A apresentação radiográfica irá depender do grau de mineralização e da fase de desenvolvimento do Odontoma. O estágio primário tem como fator principal radiolucência decorrente à falha de calcificação, no estágio intermediário a calcificação parcial poderá ser analisada, enquanto no terceiro estágio, a lesão normalmente irá se suceder com massas radiopacas circundado por áreas radiolúcidas (Torul et al, 2020).…”

Ectopic teeth in the maxillary sinus

“…Dentigerous cysts surrounding impacted teeth often displace teeth into ectopic positions [5]. Odontomas are odontogenic benign tumors composed of different dental tissues, including enamel, dentin, cementum and, in some cases, pulp tissue [6]. Odontomas of intraosseus location can cause impaction of neighboring teeth [4].…”

“…Complex odontoma is a malformation in which all tooth tissues are presented, but located in a more or less random order; whereas a compound odontoma is a malformation in which all tooth tissues form a set of toothlike structures [15]. Odontomas are usually asymptomatic and frequently revealed incidentally during x-ray examinations [6]. Case # 6 presents a complex odontoma, which made the process of eruption of the permanent upper molar impossible, and the continued growth of the tumor caused its displacement inside maxillary sinus.…”
