Descriptive aspects of odontoma: literature review

The use of cone beam computed tomography in establishing the etiology of an impacted tooth

“…21 Compound odontomas are seen as calcified structures resembling teeth within a well-defined radiolucent lesion. 5,7 A complex odontoma presents as a more or less amorphous mass with the radio-density of a tooth structure, but bearing no anatomical resemblance to a tooth, and is surrounded by a thin radiolucent area with a smooth periphery. 5 In some cases, the calcified matrix is predominant while in others there are islands of pulp tissue along with cords and buds.…”

“…4 Two dimensional radiological presentations of dental anomalies and odontogenic tumours characterized by the presence of mineralized dental tissues sometimes present a diagnostic dilemma. 5 Cone beam computed tomography (CBCT) has emerged as a viable 3D imaging modality, providing a unique perspective in orthodontic diagnosis and treatment planning of clinically missing/ impacted teeth. Images can be viewed in coronal, sagittal, oblique sections and various planes, thus offering optimal viewing and avoiding superimpositions.…”

“…They believe that the compound odontoma represents amal formation with a high degree of histomorphologic differentiation similar to the process producing supernumerary teeth, "multiple schizodontia," or locally conditioned hyperactivity of the dental lamina [1]. The etiology of the odontoma is unknown, however trauma in primary dentition, Malassez paradental remnants, inflammatory processes, odontoblastic hyperactivity and hereditary anomalie [6]. It has been suggested by Hitchin that odontomas are either inherited or are due to a mutant gene or interferences, presumably postnatal, with the genetic control of tooth development [7].…”

“…La etiología exacta de los odontomas aún no se conoce con exactitud, sin embargo, algunos autores atribuyen su origen a algunas teorías, como la teoría de los restos paradentarios de Malassez y la teoría de Rywkind, además existe una posible relación con traumatismos dentoalveolares en la dentición primaria, procesos infecciosos, hiperactividad odontoblástica y a síndromes hereditarios como es el síndrome de Gardner 2,3 . Es importante reconocer que esta patología no presenta una predilección por sexo La sutura fue con Ácido poliglicólico 5/0 y colocación de apósito (Fig.…”
