Full textLos tumores odontogénicos (TO) generalmente se comportan como lesiones benignas y tienen en su mayoría una causa desconocida. En este grupo de tumores destacan por su invasividad local y frecuencia los ameloblastomas (AM) y los tumores odontogénicos queratoquísticos (TOQ). Se describen 4 tipos de ameloblastomas, siendo los más frecuentes: Ameloblastoma Sólido/Multiquístico (A-S/M) y el Ameloblastoma Uniquístico (A-U). Tanto los ameloblastomas sólidos y uniquísticos como el TOQ son lesiones epiteliales de origen odontogénico de crecimiento lento, localmente invasivo y principalmente intraóseos por lo que requieren interactuar con el hueso adyacente para su crecimiento. Por otro lado, el quiste dentígero (QD) es una patología común en los huesos maxilares y de baja agresividad. Por lo tanto, el crecimiento de estos tumores y quistes podría involucrar cambios en los niveles de expresión de las proteínas involucradas en la formación y reabsorción ósea: receptor activador del factor nuclear ҡB (RANK), ligando de RANK (RANKL) y osteoprotegerina (OPG). En este estudio se comparó la distribución y niveles de expresión de RANK, RANKL y OPG mediante inmunohistoquímica y expresión de mRNA de rank, rankl y opg mediante RT-qPCR en casos con diagnóstico de A-S/M, A-U, TOQ y QD. La inmunomarcación de RANK, RANKL y OPG fue observada en todos las lesiones estudiadas, no encontrando diferencias significativas entre ellas, teniendo en general una distribución basal y parabasal. La inmunomarcación de RANKL tuvo un porcentaje menor en los casos de AMs, al compararlos con TOQ y QD. El patrón de marcación de RANKL fue predominantemente nuclear en todas las muestras, mientras que RANK y OPG tuvo una marcación preferentemente citoplasmática. Se observaron diferencias significativas en la expresión de rankl entre los casos de AMs, en comparación con TOQ y QD. De manera similar, los niveles de opg fueron mayores en QD comparado con TOQ y AMs y al comparar TOQ con AMs. Al comparar los resultados obtenidos por IHQ versus RT-qPCR, se observó la ausencia de correlación positiva entre la expresión de mRNA/proteína de las moléculas estudiadas. Además se observo que el sexo de los sujetos estudiados no fue determinante en la distribución de estas lesiones considerando la variable sexo de los pacientes. AMs se presentó preferentemente en pacientes adultos, mientras que TOQ y QD se presentó principalmente en niños y adolescentes. Tanto los casos de AMs y TOQ, se presentaron preferentemente en la región mandibular posterior, mientras que los casos de QD, su ubicación preferente fue de maxilar anterior. Los resultados de esta investigación permiten sugerir que es necesario expandir el análisis de los factores que intervienen en la patogénesis y desarrollo de lesiones benignas, pero con comportamiento agresivo como lo son los tumores y quistes de origen odontogénico, estudiando la regulación de RANK/rank - RANKL/rankl - OPG/opg, y de esta manera, obtener finalmente un tratamiento específico menos agresivo, que aumente la sobrevida y calidad de vida de los pacientes que padecen alguna de las lesiones estudiadas en esta investigación.

Full textAssistimos a um créscimo do número de casos em torno da Patologia Oral, seja pela constante atualização de conhecimento pelo Médico Dentista, seja pela preocupação e consciência dos doentes. Compreender e identificar os diversos quadros clínicos, saber analisar os diferentes meios complementares de diagnóstico, é essencial para um diagnóstico e um tratamento responsáveis. No âmbito dos Tumores e Quistos Odontogénicos não é diferente, já que sofreram uma recente atualização, pela Organização Mundial de Saúde (OMS), na sua classificação, tendo em conta as últimas descobertas relacionadas tanto com etiologia, como com histopatologia. Quando se aborda o Queratoquisto Odontogénico, classificado como um quisto de desenvolvimento, estamos perante uma situação clínica caracterizada por um comportamento agressivo, alta taxa de recorrência e forte associação ao Síndrome do Carcinoma Basocelular Nevóide, o que o torna num quisto único e peculiar. Podem ser encontrados em qualquer região dos maxilares, ainda que apresentem preferência pela região posterior da mandíbula. Em termos radiográficos são, muitas vezes, similares a outros tipos de quistos, no entanto, através da análise histológica o seu diagnóstico é confirmado. Quanto ao seu tratamento, diversas técnicas têm sido abordadas e discutidas na literatura, sejam elas, opções mais ou menos conservadoras. No entanto, de uma forma geral, a abordagem mais usual será a enucleação cirúrgica e a curetagem óssea ou osteotomia periférica, ainda que recentes terapêuticas tenham vinculado fortemente o seu lugar. Assim sendo, a maior preocupação prender-se-á com a possível recidiva ou com o comportamento invasivo/destrutivo que caracterizam o Queratoquisto Odontogénico, sendo por isso, de suma importância o seu diagnóstico o mais precoce possível.
We have seen an increase in the number of cases in the sphere of Oral Pathology, either due to the constant updating of knowledge by the Dentist, or due to the concern and awareness of patients. Understand and identify the various clinical signs, knowing how to analyze the different complementary exams of diagnosis, is essential for a responsible diagnosis and treatment. In the context of Odontogenic Tumors and Cysts is no different, since they have recently been updated by the World Health Organization (WHO) in their classification, taking into account the latest findings related to both etiology and histopathology. When the Odontogenic Keratocyst, classified as a developmental cyst, is approached, we are faced with a clinical situation characterized by aggressive behavior, high recurrence rate and strong association with Basal Cell Nevus Syndrome, which makes it a unique and distinctive cyst. They can be found at any region of the jaws, even if they have a preference for the posterior region of the mandible. In radiographic order, they are often similar to other types of cysts, however, through histological analysis their diagnosis is confirmed. Regarding their treatment, several techniques have been approached and discussed in the literature, whether more or less conservative options. However, in general, the most usual approach will be surgical enucleation and bone curettage or peripheral osteotomy, although recent therapies have strongly linked their place. Consequently, the major concern will be related to the possible recurrence or invasive/destructive behaviour that characterize Odontogenic Keratocyst, and it is therefore very important that its diagnosis be as early as possible.

Full textThe adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic tumor with a low recurrence rate that mainly affects female’s patients. The anterior region of the maxilla is the place of greatest predilection. The lesion is usually associated with the crown of an included tooth, commonly the canine. Rarely, the AOT can produce dentinoid material and enamel matrix, therefore, it is considered that represents a mixed odontogenic neoplasia. It consists of odontogenic epithelium in a variety of histoarchitectonic patterns and can be divided into three variants, depending on the location of the lesion and the association with an impacted tooth, namely, follicular, extrafollicular and peripheral. Given the importance of the particular characteristics of this lesion, in order to allow a correct diagnosis and treatment, the objective of the present work was to carry out a review in the literature on AOT. The methodology approach can be presented as follows: the bibliographic search was carried out with resource to database Pubmed, Science Direct and Google Scholar, carefully selecting the articles related to the topic addressed.

Full textIntrodução: O tumor odontogénico queratoquístico (TOQ) é uma lesão odontogénica intraóssea benigna relativamente frequente da cavidade oral. Localmente tem um comportamento agressivo e apresenta elevada propensão para recorrer após o tratamento, o que condiciona o prognóstico desta lesão. As características particulares desta lesão neoplásica têm gerado controvérsias na comunidade científica sobre quais as abordagens cirúrgicas indicadas para o sucesso no tratamento deste tumor. Objetivos: Analisar qual o tratamento ótimo para este tumor, de modo a garantir taxas de sucesso, prevenir futuras recorrências e garantir a qualidade de vida dos pacientes. Materiais e métodos: Foi conduzida uma pesquisa na Cochrane 1 resultado e PubMed 756 resultados. A seleção dos artigos de interesse foi efetuada a partir do resumo e de critérios de inclusão e exclusão. Três artigos entraram na análise final. Resultados: Cento e dezanove lesões foram identificadas (73 homens e 46 mulheres). Vinte e nove tumores encontravam-se na maxila e 91 na mandíbula; os métodos terapêuticos aplicados foram: marsupialização/descompressão, marsupialização seguida de enucleação e terapias adjuvantes (ostectomia periférica e solução de Carnoy), enucleação simples, enucleação e aplicação de solução de Carnoy, enucleação e ostectomia periférica, enucleação com ostectomia periférica e aplicação de solução de Carnoy e resseção em bloco. Discussão e conclusões: Foi possível verificar que o tratamento do tumor através de enucleação em combinação com terapias adjuvantes está associado a uma menor taxa de recorrência, quando comparado com os TOQ submetidos apenas a enucleação simples. A amostra reduzida de TOQ submetidos a resseção em bloco e marsupialização seguida de enucleação com terapias adjuvantes não permitiu obter resultados estatisticamente relevantes. São portanto necessários mais estudos com critérios bem definidos, de modo a que seja possível uma análise adequada das taxas de recorrência em função da modalidade de tratamento.
Background: The keratocystic odontogenic tumor (KCOT) is a benign intraosseous odontogenic lesion relatively frequent in the oral cavity. It has a locally aggressive behavior and exhibits a high propensity to recur after treatment, which affects the prognosis of this lesion. All the singular characteristics of this neoplasic lesion have originated controversy in the scientific community regarding which are the most indicated surgical approaches for the successful treatment of this tumor. Objectives: To analyze which is the optimal treatment for this tumor, in order to guarantee high success rates of treatment, prevent future recurrences and allow the maintenance of the patients quality of life. Materials and methods: A search was conducted in Cochrane 1 result and in PubMed 756 results. The selection of the articles was based on the abstracts and inclusion and exclusion criteria. Three were considered for the final analysis. Results: One hundred nineteen lesions were identified (73 males and 46 females). Twenty nine tumors were found in maxilla and 91 in mandible; therapeutic methods applied were: marsupialisation/decompression, marsupialisation followed by enucleation and adjunctive therapies (peripheral ostectomy and Carnoy’s solution), enucleation alone, enucleation and Carnoy’s solution, enucleation followed by peripheral ostectomy and Carnoy’s solution and resection. Discussion and conclusions: Treatment by enucleation in combination with adjunctive measures is associated with minor recurrence rates when compared with enucleation alone. The small number of KCOT that were treated with bloc resection didn’t allow us to obtain statistically relevant results. Therefore, more studies are necessary, with well established criteria, in order to allow an adequate analisys of the recurrence rates associated with each treatment modality.

Full textThe aim of this study is to report and classify the types of odontoma, with emphasis on complex odontoma, and its epidemiological aspects, etiology, location, clinical, radiographic and histological characteristics, differential diagnosis, prognosis and treatment over the time, and postoperative complications, based on a classic literature review. The odontoma is the most common odontogenic tumor and it’s considered an anomaly of development. It also can be classified in two types: complex and compound. The etiology of these tumors is unknown, nevertheless, may be related with included teeth, trauma, local infection or hereditary factors. Their growth is typically slow and asymptomatic. Treatment consists on conservative surgical enucleation removal followed by histopathological analysis and has a positive prognosis.

Full textThis monograph aims to address the odontogenic myxoma, which is one of the most frequent odontogenic tumors currently, using bibliographical research. The odontogenic myxoma is defined as being a benign odontogenic neoplasm with mesenchymal origin. It is characterized by slow increase, asymptomatic and locally aggressive, with high recurrence rate. Usually, it appears mostly in females in the age range between the second and fourth decades of life. Its incidence in the mandible predominates, although the cases in the maxilla present greater severity. This odontogenic tumor is devoid of a capsule, thus presenting an infiltrative behavior. In these cases, its treatment is surgical, depending on the clinical situation, and a periodic surveillance will always be necessary, taking into account its recurrence rate.

Full textCementoblastoma is a rare benign lesion that represents less than 1% to 6% of all odontogenic tumours (Milani et al. 2012; Borges et al. 2019). It is characterised by proliferation of cementum-like tissue and in all cases tends to be associated with an erupting permanent tooth, most often the first molar. This paper presents a clinical case, little reported in the literature due to its dimensions, of a cementoblastoma that affected the left mandibular body, extending from the canine to the first premolar, of a 15-year-old woman. Surgery was performed under general anaesthesia, with total excision of the lesion being excited and sent for histological analysis. The particularity of the following case was the extremely fragile bone remnant structure after the removal of the lesion, which had a size of 28×24 mm. This fragility led to the need to use osteosynthesis plates and intermaxillary blockage, seeking to avoid iatrogenic fracture of the mandible, together with the surgical site being regenerated with an iliac crest graft together with autologous and synthetic bone. The patient was monitored for 9 months after surgery and showed no signs of recurrence.
