Odontoma compuesto: revisión de la literatura y reporte de un caso con 40 dentículos / Compound odontoma: a review of the literature and report of a case involving 40 denticles

El odontoma compuesto es un tumor benigno odontogénico conformadopor varios dentículos o dientes rudimentarios los cuales se encuentran conformados de tejido dental organizado. Su etiología no está biendefi nida pero se atribuye a traumatismos durante la primera dentición, así como a procesos infl amatorios o infecciosos, anomalías hereditarias o alteraciones en el gen de control del desarrollo dentario. Su presencia se encuentra entre los tres tumores odontogénicos más frecuentes, en diferente orden según el autor que se consulte. Está relacionado por logeneral con una alteración en la erupción o malposición dental. Tiene predilección en hueso maxilar, frecuentemente asintomáticos, se caracterizan por un crecimiento lento, diagnosticándose de forma casualmediante exámenes radiográfi cos de rutina entre la segunda y terceradécada de la vida. En este estudio se presenta el caso de un pacientefemenino de 14 años de edad, con presencia de un odontoma compuestode 40 dentículos, en la región parasinfi siaria izquierda, tratado medianteenucleación, y colocación de injerto óseo.

The compound odontoma is a benign odontogenic tumor composed ofseveral denticles or rudimentary teeth made up of organized dentaltissue. Its etiology is not well defi ned but is attributed to trauma duringthe fi rst dentition, as well as to infl ammatory or infectious processes, inherited abnormalities, odontoblastic hyperactivity or alterations in the gene that controls tooth development. It is among the 3 mostcommon odontogenic tumors, though its ranking among these varies depending on the author consulted. It is usually associated with analteration in the eruption or malposition of teeth. It has a predilection for the maxillary bone, and is often slow-growing and asymptomatic. Odontomas are diagnosed incidentally during routine X-ray examinations of patients between the second and third decades of life. In this study, we present the case of a 14-year-old female patient with the presence of a compound odontoma comprised of 40 denticles inthe left parasymphyseal region, which is treated by enucleation andbone graft placement.

Unusual Form of Complex Odontome: A Case Report.

Odontomas are the most characteristic among odontogenic tumors of the jaws, which are benign, slow-growing and non-aggressive. There are various theories, or etiological factors were quoted for occurrences of odontomas. Being asymptomatic in nature sometimes it may interfere with the eruption of the associated tooth leading to impaction or delayed eruption. Most of the lesions are diagnosed accidently on routine radiological examination in the second and third decades of the life. The sole management mainly depends on the early diagnosis, histopathological examination and surgical removal of the lesion. Here, we were presenting an interesting case of unusually large complex odontoma associated with pain, as well as missing molar is reported.

Compound Odontoma Associated with Impacted Teeth: A Case Report.

Odontomas are developmental anomalies of the dental tissues and may interfere with the eruption of the associated tooth. Since, these lesions are asymptomatic, they are usually detected in routine radiographs only. Early diagnosis, prompt clinical decision making followed by a proper treatment at the right time, results in a favorable prognosis. The present report describes the surgical management of a case of compound odontoma in 11-year-old boy who presented with a complaint of missing tooth in maxillary anterior region. After the lesion was surgically removed under local anesthesia, histopathological examination confirmed the diagnosis of compound odontoma. The related literature is also reviewed in this article.

Prevalência de lesões compatíveis com odontoma em radiografias panorâmicas de uma clínica radiológica / Prevalence of lesions compatible with odontoma in the panoramic radiographs of a radiological clinic

Objetivo: Verificar a prevalência de lesões compatíveis com odontoma em radiografias panorâmicas de pacientes atendidos na Clínica Radiológica do Centro de Pesquisas Odontológicas São Leopoldo Mandic, em Campinas (SP), entre 2003 e 2007. Métodos: Foi realizado um estudo radiográfico, retrospectivo, de 1 130 radiografias panorâmicas, sendo 1 077 convencionais e 53 digitais. Deste total, 580 eram de pacientes do gênero feminino e 550 do gênero masculino. Resultados: Em duas radiografias foram observadas imagens compatíveis com odontoma composto. Uma de paciente masculino, de 10 anos de idade, que apresentava o dente incisivo central superior direito não irrompido na maxila associado à imagem compatível com a lesão, e uma paciente feminino, de 16 anos, com canino inferior esquerdo não irrompido na mandíbula associado à imagem com dentículos. Conclusão: Os odontomas são tumores odontogênicos benignos, frequentemente, detectados em radiografias e cujas imagens, em decorrência das características patognomônicas, permitem o diagnóstico de odontoma composto.

Objective: The objective of this study was to verify the prevalence of lesions compatible with odontoma in the panoramic radiographs of patients seen at the Radiological Clinic of the São Leopold Mandic Research Center in Campinas, SP, Brazil, in the years 2003 to 2007. Methods: A retrospective radiographic study of 1130 panoramic radiographs was conducted where 1077 were conventional and 53 were digital. Of the total, 580 radiographs belonged to females and 550 to males. Results: The images of two radiographs were compatible with compound odontoma. One belonged to a 10-year-old boy who had an unerupted right maxillary central incisor associated with the image compatible with the lesion. The other belonged to a 16-year-old female patient who had an unerupted left mandibular canine associated with an image with denticles. Conclusion: Odontomas are benign odontogenic tumors frequently detected in radiographs and the images allow compound odontomas to be diagnosed because of their pathognomonic features.

A survey of oral and maxillofacial biopsies in children: a single-center retrospective study of 20 years in Pelotas-Brazil

Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB) at the Dental School of the Federal University of Pelotas (UFPEL), comprising a 20-year period (1983-2002). From the total of 9,465 biopsies received in this period, 625 (6.6%) were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89 percent of the cases occurred in patients aged 7 to 14 years (53% in females and 47 percent in males). Mucocele (17.2%) was the most common type of lesion, followed by dentigerous cyst (8.6%). In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%). Malignant lesions were observed in a small section of the sample (1.2%). Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.
