ABSTRACT

Objetivo: Presentar el caso de una patología poco común como es el fibro-odontoma ameloblástico (FOA), su manejo interdisciplinario y su resolución quirúrgica. Caso clínico: En este reporte de caso describimos un FOA en una paciente de 10 años, ubicado en el cuerpo mandibular derecho, asociado a las raíces de molares temporales que generó la retención de premolares. Se realizó la enucleación completa de la lesión, exodoncia de los temporales asociados y se decidió mantener los dientes definitivos y esperar su erupción espontánea. Es importante considerar la posibilidad de mantener el diente retenido si este no dificulta la exéresis de la lesión, ya sea para su erupción espontánea o rescate ortodóntico, lo cual es posible observar en este caso en el que se aprecia una evolución intraósea favorable. Con respecto al seguimiento, se recomienda el control a largo plazo con el fin de controlar la erupción del órgano dentario o la aparición de posibles recidivas (AU)


Aim: To present a clinical case of a rare pathology, the ameloblastic fibro odontoma (AFO), its interdisciplinary management and its surgical resolution. Clinical case: In this case report we describe an AFO in a 10-years-old patient, localized in the right hand side of the body of the mandible, associated with the roots of temporary molars that generated the retention of the premolars. Complete enucleation of the lesion and the extraction of the associated temporary molars were performed. It was decided to keep the permanent teeth and to wait for their spontaneous eruption. It is important to consider the possibility of keeping the retained teeth if it does not hinder the excision of the lesion, either for its spontaneous eruption or orthodontic rescue, which is possible to see in this case, in which a favorable intraosseous evolution is appreciated. With regard to follow-up, long-term monitoring is recommended in order to control the eruption of the dental organ or the appearance of possible recurrences (AU)

ABSTRACT

ABSTRACT: The appearance of mixed odontogenic tumors into the oral cavity is a rare event. It is considered that some mixed tumors are only a stage in the complete development of a hamartomatous formation such as ameloblastic fibroodontoma and odontoma. Both pathologies share in common cellular elements which at one point makes them indistinguishable from each other. We present the case of a 21 year old patient who showed a mandibular growth whose histological elements present characteristics of both pathologies. The treatment was surgical excision of the lesion. There were no complications or recurrences to periodic reevaluation.


RESUMEN: La aparición de tumores odontogénicos mixtos en la cavidad oral es un evento raro. Se considera que algunos tumores mixtos son solo una etapa en el desarrollo completo de una formación hamartomatosa como el fibro-odontoma ameloblástico y odontoma. Ambas patologías comparten elementos celulares comunes que en un punto los hacen indistinguibles entre sí. Presentamos el caso de un paciente de 21 años que mostró un crecimiento mandibular cuyos elementos histológicos presentan características de ambas patologías. El tratamiento fue la escisión quirúrgica de la lesión. No hubo complicaciones o recurrencias a la reevaluación periódica.

ABSTRACT

Hybrid lesions of the oral cavity are infrequent and share characteristics with a number of other pathologies. both odontomas and dentigerous cysts are of odontogenic origin, but their simultaneous occurrence is rare and scarce. clinical and radiographic examinations are not conclusive, making their identification difficult, while histopathological studies can reveal their defining characteristics. the aim of this report was to describe the radiographic and histomorphological findings of a hybrid lesion formed by a complex odontoma and a dentigerous cyst, affecting the mandible of a 22-year-old man, from Cartagena, Colombia, who had no relevant medical history, and no symptoms or discomfort in the affected area.

ABSTRACT

RESUMEN: Los odontomas son los tumores odontogénicos benignos más prevalentes. Estos están conformados por tejido dentario, epitelio odontogénico y tejido mesenquimático. Se dividen en dos subtipos: odontomas compuestos, que presentan tejidos dentarios normales, pero con una alteración en su conformación y tamaño, y odontomas complejos, que presentan tejidos dentarios bien formados, pero rodeados de tejido desorganizado. Se presentan tres casos de pacientes sexo femenino, quienes acuden para evaluación y tratamiento debido al hallazgo radiográfico de odontoma compuesto. En el caso nº 1 se realizó la desinclusión del diente impactado, la exodoncia del diente remanente, la exéresis del odontoma compuesto, la instalación de un implante dental en el alveolo de la zona intervenida y, finalmente, el posicionamiento de injerto óseo. En el caso nº 2 se realizó la exodoncia del diente temporal remanente y la exéreis del odontoma compuesto. Ambos casos evolucionaron de manera favorable sin complicaciones post operatorias. En el caso nº 3 se realizó la fenestración del diente 18 y la exéreis del odontoma compuesto que retenía su erupción. Todos los casos evolucionaron de manera favorable sin complicaciones post operatorias. Dada la prevalencia de esta patología, es necesario un adecuado conocimiento sobre ella y sus características, para realizar un adecuado diagnóstico y tratamiento. Existen distintas medidas terapéuticas respecto a la rehabilitación de una zona edéntula como resultado de la exéresis de estos tumores. Esto depende principalmente de la edad del paciente. Al ser requeridas medidas rehabilitadoras, un punto importante a considerar es la posibilidad de realizar todos los procedimientos quirúrgicos en un solo tiempo operatorio.


ABSTRACT: Odontomas are the most common benign odontogenic tumors and are composed of dental tissue, odontogenic epithelium and mesenchymal tissue. They are divided into two subtypes: Compound odontomas, which present normal tooth tissue, but an alteration in their conformation and size, and complex odontomas, which present well-formed tooth tissue, but are surrounded by disorganized tissue. A bibliographic review was performed by one operator in Pubmed and Epistemonikos. After filtering by title and abstract, only one systematic review was selected. We present two clinical cases of compound odontoma in female patients at the Military Hospital in Santiago. Patients were referred for evaluation and treatment due to the radiographic finding of compound odontoma. In case # 1, the impacted tooth was disincluded, the remaining temporal tooth was extracted, and excision of the compound odontoma carried out; subsequently a bone graft implant was placed in the remaining socket. In case # 2, the remaining temporal tooth was extracted and compound odontoma excised. After that, natural eruption of the corresponding permanent tooth is expected. In case # 3, tooth 1.8 fenestration and excision of compound odontoma was performed. In this case also, natural eruption of the corresponding permanent tooth is expected. Given the prevalence of this pathology, adequate knowledge of compound odontomas and their characteristics is necessary for proper diagnosis and treatment. There are different therapeutic measures for the rehabilitation of an edentulous area following excision of compound odontoma. This depends mainly on the age of the patient. When rehabilitation measures are required, an important aspect to consider for the patient, is the possibility of a single surgical event, as was done in case # 1.

ABSTRACT

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.

ABSTRACT

Ameloblastic fibrosarcoma is a rare odontogenic neoplasm and is considered the malignant counterpart of ameloblastic fibroma. The diagnosis is made by histopathological and immunohistochemical evaluation, since the epithelial component remains benign and the mesenchymal component becomes malignant. Until 2012, only 72 cases were published in English-literature. This article presents a case of intraoral mass at the posterior mandible of a 23 year-old female patient. Panoramic radiography showed a multilocular radiolucent lesion with ill-defined borders and tooth involvement. The mandibular canal presented loss of architecture also. The computed tomography images (bone window) showed hypodense lesion leading to expansion, tapering and irregular destruction of cortical, and tooth involvement. Incisional biopsy was performed for histopathological evaluation. The results revealed a mixed lesion with epithelial and mesenchymal cellular proliferation. At immunohistochemical analysis, the mesenchymal portion was vimentin positive and the epithelial component was positive for cytokeratin AE1-AE3. It also showed p53 intense labeling in all tumorous cells. The final diagnosis was ameloblastic fibrosarcoma. The lesion was surgically excised with clear margins. The radiographic appearance, even imperative for treatment planning, poorly contributed to final diagnosis, which was reached by histopathological and immunohistochemical evaluations. The treatment is still controversial, without a definition regarding chemotherapy and radiotherapy as coadjutant treatment(AU)


El fibrosarcoma ameloblástico es una neoplasia odontogénica poco frecuente y es considerada la contraparte maligna del fibroma ameloblástico. El diagnóstico se realiza mediante la evaluación histopatológica e inmunohistoquímica, ya que el componente epitelial sigue siendo benigno y el componente mesenquimal se convierte en maligno. Hasta 2012, solo 72 casos fueron publicados en la literatura inglesa. En este artículo se presenta un caso de masa intraoral en la mandíbula parte posterior, de una paciente de 23 años de edad. La radiografía panorámica mostró una lesión radiolúcida multilocular con bordes mal definidos y con un diente incluso en la lesión. El canal mandibular también presentaba pérdida de la arquitectura. La tomografía computarizada (TC) (ventana de hueso) presentó lesión hipodensa que provocaba una expansión que se estrechaba y destruía irregularmente la cortical, además envolvía la pieza dentaria. Se realizó biopsia incisional para evaluación histopatológica. Los resultados revelaron una lesión mixta con proliferación celular epitelial y mesenquimal. En el análisis inmunohistoquímico, la porción mesenquimal fue positivo para vimentina y el componente epitelial fue positivo para citoqueratina AE1-AE3. También mostró marcación intensa para p53 en todas las células tumorales. El diagnóstico final fue de fibrosarcoma ameloblástico. La lesión fue extirpada quirúrgicamente con márgenes de seguridad. El aspecto radiológico, aunque imprescindible para la planificación del tratamiento, poco contribuyó al diagnóstico final, que fue alcanzado por las evaluaciones histopatológicas e inmunohistoquímicas. El tratamiento sigue siendo controvertido, sin una definición respecto de la quimioterapia y la radioterapia como tratamiento coadyuvante(AU)

ABSTRACT

Los odontomas están compuestos de esmalte, dentina, cemento y tejido pulpar. Histológicamente se clasifican en 2 grupos: compuestos y complejos, mientras que clínicamente se clasifican en 3 tipos: odontoma central (intraóseo), odontoma periférico (extraóseo o de los tejidos blandos) y odontoma erupcionado. Epidemiológicamente son reportados como los tumores odontogénicos más frecuentes, sin embargo la erupción de este tipo de lesión es poco común, produciéndose en el 1,6% de los casos. Por lo general son asintomáticos, siendo comúnmente un hallazgo radiográfico, y en algunos casos pueden estar asociados con alteraciones de la erupción dentaria. Este estudio corresponde a un caso clínico de un odontoma complejo de gran tamaño que erupciona en la cavidad oral asociado a un molar retenido.


Odontomas consist of enamel, dentin, cementum, and pulp tissue. Histologically, they are classified into 2 groups: compounds and complexes. They are also clinically classified into 3 types: Central odontoma (intraosseous), peripheral odontoma (extraosseous or soft tissue odontoma) and erupted odontoma. Epidemiologically they are reported as the most frequent odontogenic tumor, however, the eruption of this type of lesion is rare, and odontoma occurs only in 1.6% of cases.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

Objetivo: el objetivo de este trabajo es describir los odontomas compuestos desde una perspectiva actual, a partir de casos clínicos. Casos clínicos: se presentan cuatro casos de niños a los que se les realizó la enucleación de un odontoma, cuyas biopsias confirmaron el diagnóstico inicial. En los controles a distancia, no se registraron recidivas en ninguno de los casos. Conclusión: un odontoma compuesto está constituido por esmalte, dentina y, ocasionalmente, cantidades variables de cemento y pulpa que forman un conjunto de estructuras similares a dientes denominadas dentículos. Su etiología es desconocida. Son asintomáticos, por lo cual, generalmente, se diagnostican como hallazgos radiográficos. El tratamiento consiste en la escisión quirúrgica del odontoma.

ABSTRACT

A impacção de incisivos superiores na fase de dentição mista, além de ser um desafio clínico, é uma má oclusão que preocupa os pais e as crianças, haja vista que afeta a estética do sorriso. Nesses casos, o diagnóstico precoce e o tratamento adequado são importantes para a melhor resolução do problema, tanto do ponto de vista funcional quanto psicológico. Um dos fatores etiológicos da impacção dentária é a presença de odontoma no trajeto de erupção do dente permanente. O tratamento ortodôntico-cirúrgico dessa má oclusão promove a erupção, posicionamento e estabilização do dente retido, além da remoção da patologia. Dessa maneira, o objetivo do presente estudo é apresentar um relato de caso clínico da remoção cirúrgica de odontoma e tracionamento do incisivo retido, com a utilização de aparelho ortodôntico removível. O aparelho foi utilizado de início para proporcionar abertura de espaço necessária à erupção do dente retido, sendo, depois, utilizado para tracioná-lo e posicioná-lo adequadamente na arcada. Os procedimentos adotados mostraram-se uma alternativa eficiente para o tratamento de dentes impactados, além de apresentarem baixo custo e boa aplicabilidade.

ABSTRACT

The main goals of this report were to describe the surgical procedure and a three-year clinical/radiographic follow-up of a child with compound or combined odontoma. Discussion: In the majority of cases, diagnoses of odontoma are made during the development and eruption of permanent dentition, at the time when the patient is providing the documentation for having orthodontic and/or orthopedic treatment performed. In this case, the diagnosis and treatment were established earlier, before the patient entered the first stage of mixed dentition. This procedure favored normal development of permanent teeth in the maxillary anterior region preventing aesthetic, occlusion and phonation problems. Conclusion: The surgical removal of an odontoma diagnosed early (still in primary dentition), after careful clinical and radiographic analysis of the location, stage of formation and position of the teeth, is an approach which, in the majority of cases, favors eruption and alignment of permanent teeth...


Os objetivos principais deste relato foram o de descrever o procedimento cirúrgico e o acompanhamento clínico/radiográfico por três anos de criança portadora de odontoma composto ou combinado.Discussão: Na maioria das vezes, o diagnóstico de odontoma é realizado durante o desenvolvimento e erupção da dentição permanente, no momento em que o paciente está providenciando sua documentação para realização de tratamento ortodôntico e/ou ortopédico. No presente caso, o diagnóstico e o tratamento foram estabelecidos precocemente, antes de iniciar a primeira fase da dentadura mista. Esta conduta favoreceu o desenvolvimento normal dos dentes permanentes da região anterior superior evitando problemas de estética, oclusão e fonação. Conclusão: A remoção cirúrgica de odontoma diagnosticado precocemente (ainda na dentição decídua), após criteriosa análise clinica e radiográfica da localização, estágio de formação e posicionamento dos dentes, é uma conduta que, na maioria das vezes, favorece o irrompimento e alinhamento dos dentes permanentes...

ABSTRACT

This paper describes an exceptional case of an enormous complex odontoma affecting the mandibular symphysis of a 9-year-old boy. Because of its dimensions, the lesion produced cortical bone expansion, dental displacement and impactation, which are clinical signs very seldom described for odontomas. The lesion was surgically excised in a conservative way using an intraoral approach with local anesthesia. After 7 years of follow up, all teeth had erupted and the mandibular bone healed totally. Because of its radiographic mixed radiolucent and radiopaque appearance and its expansive growth, it is imperative to make the differential diagnosis of giant complex odontoma for other more aggressive mixed odontogenic tumors, such as ameloblastic fibro-odontoma, odotoameloblastoma and cystic calcified odontogenic tumor. Conservative approach appears to be indicated in the treatment of such lesions.


Descrevemos um caso excepcional de um odontoma complexo gigante afetando a sínfise mandibular em um menino de nove anos de idade. Devido à sua dimensão esta lesão produziu expansão da cortical óssea, deslocamento dentário e impactação, sinais clínicos muito raramente descritos para odontomas. A lesão foi extirpada cirurgicamente de forma conservadora, utilizando uma abordagem intra-oral com anestesia local. Depois de sete anos de seguimento todos os dentes se encontram erupcionados e o osso mandibular totalmente curado. Devido à sua aparência radiográfica, mista radiolúcida e radiopaca, e seu crescimento expansivo, é imperativo fazer o diagnóstico diferencial de odontoma complexo gigante para outros tumores odontogênicos mistos mais agressivos, como o fibro-odontoma ameloblástico, odotoameloblastoma e tumor odontogênico cístico calcificante. Uma abordagem conservadora parece ser indicada no tratamento dessas lesões.

ABSTRACT

O termo carcinoma ameloblástico é usado para descrever ameloblastomas com características histológicas de malignidade. Lesões desse tipo podem ocorrer em uma extensa faixa etária, sendo mais comum na quarta década de vida. Não há predileção aparente por sexo, a área mais comumente afetada é a porção posterior da mandíbula, envolvendo em menor proporção a maxila. Por se tratar de um tumor com poucos casos descritos na literatura, o objetivo deste trabalho foi relatar um caso de carcinoma ameloblástico em paciente do sexo feminino, 38 anos, com queixa de dor e assimetria facial. Ao exame clínico intrabucal observou-se um aumento de volume em região posterior de mandíbula, do lado direito. A tomografia computadorizada revelou adelgaçamento das corticais com presença de área hipodensa homogênea. Foi realizada biópsia incisional cujo diagnóstico histológico inicial foi de ameloblastoma, sem características citológicas de malignidade. Baseando-se no exame histopatológico, optou-se pelo tratamento cirúrgico da lesão através da ressecção parcial da mandíbula. A peça cirúrgica foi encaminhada ao laboratório obtendo-se novo diagnóstico de carcinoma ameloblástico. Provavelmente, a diferença do diagnóstico histológico final para o inicial pode estar relacionada ao fato de o carcinoma ameloblástico apresentar áreas focais semelhantes ao ameloblastoma. Após 6 meses da cirurgia, a paciente apresentou metástase tumoral no pulmão e encontra-se sob supervisão médica(AU)


El término carcinoma ameloblástico es utilizado para describir ameloblastomas con características histológicas de malignidad. Este tipo de lesión puede ocurrir en cualquier edad, pero se puede observar con mayor frecuencia en la cuarta década de vida. No existe aparentemente un sexo predominante. El área más comúnmente afectada es la porción posterior de la mandíbula y afecta en menor proporción el maxilar. Por ser un tumor con pocos casos relatados en la literatura, el objetivo de este trabajo fue presentar un caso de carcinoma ameloblástico en un paciente del sexo femenino con 38 años de edad, que acudió a la consulta por presentar síntomas dolorosos y asimetría facial. Al examen clínico intrabucal se observó un aumento de volumen en la región posterior derecha de la mandíbula. La tomografía computadorizada mostró un adelgazamiento de las corticales con presencia de un área hipodensa homogénea. Fue realizada una biopsia incisional y su diagnóstico histológico inicial fue de un ameloblastoma sin características citológicas de malignidad. Después de realizado el examen histopatológico se optó por el tratamiento quirúrgico de la lesión con resección parcial de la mandíbula. La estructura quirúrgica fue enviada al laboratorio, donde se obtuvo un nuevo diagnóstico de carcinoma ameloblástico. Probablemente la diferencia del diagnóstico histológico final con el inicial pudo estar relacionada con el hecho de que el carcinoma ameloblástico presenta áreas en foco semejantes al ameloblastoma. Luego de 6 meses del procedimiento quirúrgico, la paciente presentó metástasis tumoral en el pulmón y se encuentra bajo supervisión médica(AU)


The term ameloblastic carcinoma is used to describe the ameloblastomas with histological characteristics of malignancy. This type of lesion may to occur in any age, but it may be more frequent observed in the fourth decade of life. The is not apparently a predominance sexual. The commonest involved area is the posterior portion of mandible involving in less extent the maxillary. This is a tumor with few cases mentioned in the literature, thus, the aim of present paper was to present a case of ameloblastic carcinoma in a female patient aged 38 came to consultation due to painful symptoms and facial asymmetry. In intrabuccal clinical examination it was noted a volume increase in the right posterior region of mandible. The computed tomography showed a slimming of the cortex with presence of a homogenous hypo-dense area. An incisional biopsy was made and its initial histological diagnosis was an ameloblastoma without histological characteristics of malignancy. After histopathological examination the surgical treatment of lesion was prescribed with a partial resection of mandible. The surgical structure (sample) was sent to laboratory to obtain a new diagnosis of ameloblastic carcinoma. It is probable that the difference of final histological diagnosis with the initial one could be related to the fact that the ameloblastic carcinoma has focal areas similar to ameloblastoma. After 6 months of surgical procedure the patient had tumoral lung metastasis and is under medical supervision(AU)

ABSTRACT

PURPOSE: This study reports a case of a extensive odontoma causing maxillary sinusitis. CASE DESCRIPTION: A 25-year-old man at clinical examination revealed discrete facial asymmetry and exposure of the lesion in the oral cavity. Imaging exams showed the presence of a well-defined radiopaque mass in the left maxilla, measuring approximately 7 cm and was intimately associated with the maxillary sinus and oral cavity. The mass was excised through an intraoral access under general anesthesia in the hospital and sent for histopathology, which was diagnosed as complex odontoma. The patient is under clinical follow-up and shows no signs of maxillary sinusitis and no oral sinus fistula. CONCLUSION: The odontoma is a common injury in clinical dentistry, but in some aggressive cases may cause sequelae in the patient, thus, caution the dentist for proper diagnosis and treatment.


OBJETIVO: Este estudo relata a apresentação de um extenso odontoma causando sinusite maxilar. DESCRIÇÃO DO CASO: Um homem de 25 anos ao exame clínico revelou assimetria facial discreta e exposição da lesão na cavidade oral. Os exames de imagem mostraram a presença de uma massa radiopaca bem definida na maxila esquerda, medindo aproximadamente 7 cm e estava intimamente associado com o seio maxilar e a cavidade oral. A massa foi extirpada através de um acesso intra-oral, sob anestesia geral em ambiente hospitalar e enviada para estudo histopatológico, onde foi diagnosticada como odontoma complexo. O paciente está sob acompanhamento clínico e não mostra sinais de sinusite maxilar e fístula bucossinusal. CONCLUSÃO: O odontoma é uma lesão comum na clínica odontológica, mas pode, em alguns casos, se apresentar de forma agressiva levando a danos ao paciente, e desta forma, é necessária atenção do cirurgião dentista para o correto diagnóstico e tratamento.

ABSTRACT

Compound odontoma is stated to be a hamartomatous lesion rather than a true odontogenic tumour. It has an unknown etiology and often suspected when there are retained deciduous teeth in children. Early detection and surgical enucleation of the tumour is recommended to prevent impaction of unerupted teeth. In this index case, multiple denticles or rudimentary teeth, numbering 37 were enucleated from the maxillary anterior region of a 17-year old male, which makes this case unusual. Evidence of concrescence, fusion and dilaceration were observed in the denticles enucleated, the size of which varied from 4 mm to 12.5 mm

ABSTRACT

O presente trabalho apresenta o caso de uma paciente encaminhada à clínica de Estomatologia para avaliação de uma lesão intraóssea na maxila. Graças aos exames tomográficos computadorizados por feixe cônico (cone beam), observou-se uma extensa área hiperdensa, de evolução indeterminada, na região posterior de maxila do lado esquerdo. O diagnóstico presuntivo foi de odontoma complexo. O exame microscópico revelou presença de conglomerado irregular de esmalte, dentina, cemento e tecido pulpar. O diagnóstico final foi de odontoma complexo. A paciente encontra-se em proservação de 6 meses, sem sinais clínicos e radiográficos de recidiva.
