Compound odontoma: a case study.
ABSTRACT Odontomas are the most common odontogenic tumors and are usually incidental findings in radiographic examination. They are classified as either compound or complex. Both types are composed of enamel, dentin, cementum, and pulp tissues. Compound odontomas appear radiographically as rudimentary toothlets and can be diagnosed from radiographs alone, while complex odontomas appear as indistinguishable radiopaque masses and require resection for definitive diagnosis. They are frequently found in association with other abnormalities, and surgical excision is recommended for both types by most practitioners. The possibility of discovering lesions such as the odontoma supports the practice of recommending baseline radiographic surveys for all dental patients.

ABSTRACT: Ectopic odontomas are a rare disease process and need to be in the differential of the Otolaryngologist and Radiologist. Previous reports reveal the most common location to be the maxilla. We present a rare case of odontoma involving a turbinate causing nasal obstruction and foul-smelling rhinorrhea. Surgical excision is the treatment of choice with an endoscopic approach, if feasible.

ABSTRACT: Here we present the developmental progression of bioengineered pig teeth from 1 to 25 weeks of development. We demonstrate that 2-25 week implants contained embryonic tooth bud- and cap-stage tooth structures consisting of dental epithelium expressing the sonic hedgehog gene and condensed dental mesenchyme. Implants harvested at 18-25 weeks also contained tooth bud-like structures, as well as mature tooth structures containing enamel, dentin and pulp tissues. Immunohistochemical analyses confirmed the expression of dentin- and enamel-specific proteins in differentiated bioengineered tooth tissues. Three-dimensional computer modelling further demonstrated a spatial organization of enamel, dentin and pulp tissues resembling that of natural teeth. We conclude that bioengineered teeth commonly exhibit morphological stages characteristic of naturally forming teeth. Furthermore, the presence of immature tooth buds at all times assayed and increased numbers of bioengineered tooth structures over time suggests that porcine dental progenitor cells maintain the ability to form teeth for at least 25 weeks.Archives of Oral Biology 03/2005; 50(2):259-65.

ABSTRACT: Os odontomas constituem-se como os tumores odontogénicos mais comuns, sendo defini-dos como uma malformação benigna, em que as células alcançam completa diferenciação, atingindo o estágio, no qual todos os tecidos dentais estão representados. São classificados em odontomas complexos e compostos. Normalmente, são assintomáticos e diagnosticados através de exames radiográficos de rotina. O tratamento para este tipo de lesão é a exérese cirúrgica e o prognóstico é excelente. O objetivo deste trabalho é realizar uma revisão da literatura sobre o assunto e apresentar um caso de odontoma composto de uma paciente de 26 anos do género feminino atendida na clínica de Estomatologia da Faculdade de Odonto-logia da PUC Minas. Odontoma Hamartoma a b s t r a c t Odontomas consists as the more common odontogenic tumors, being defined as a benign malformation, in which the cells attain complete differentiation, reaching the stage in which all dental tissues are represented. They are classified complex and compound odontomas. They are usually asymptomatic and diagnosed by routine radiographic examination. The treatment for this type of lesion is surgical excision and the prognosis is excellent. This paper aim is to review literature on the subject and present a case of compound odontoma in a 26 years female patient treated in the Stomatology clinic of the School of Dentistry at PUC Minas., está totalmente proibida a transmissão deste documento por qualquer meio ou forma.Revista portuguesa de estomatologia e cirurgia maxilo-facial 12/2013; DOI:10.1016/j.rpemd.2012.06.002
