Identificação de regiões císticas dentárias em imagens de radiografia panorâmic...
Oliveira, Danilo Alves; Sousa, Leila Maria Rodrigues de; Sampieri, Marcelo Bonifácio da Silva; Chaves, Filipe Nobre; Paula Júnior, Iális Cavalcante deThe dental cyst is a pathology that presents characteristics of expansion and bone absorption, its early identification is fundamental for the treatment. Several computer vision systems seek to carry out the identification of cysts. Therefore, the present research aims to provide a methodology for automatic identification of cystic regions in radiographic examinations. For this, investigations of initial segmen...

Mourão, Ana Cecília Carenina Machado; Souza, Antônio Odacy; Chaves, Filipe Nobre; Oliveira, Denise Helen Imaculada Pereira deImaging exams combined with clinical aspects are of paramount importance for the correct diagnosis and treatment of the problem case experienced by patients who seek health services. Among the exams we can mention the Panoramic Radiography (PR) and the Cone Beam Computed Tomography (CBCT), which have several indications in the dental field. The objective of this work was to analyze the main indications for carr...
Conservative management of an extensive odontogenic keratocyst in the anterior ...
Chaves, Filipe Nobre; Fernandes, Jefferson Douglas Lima; França, Samuel Rocha; Oliveira, Denise Hélen Imaculada PereiraOdontogenic keratocysts (OKCs) are now considered benign cysts of odontogenic origin that are characterized by an aggressive behavior with a relatively high recurrence rate, particularly when OKCs are associated with syndromes. Its histological appearance is characteristic with the presence of an epithelial lining parakeratinized showing a corrugated surface, together with a number of architectural features of ...
Peripheral odontogenic myxoma: Clinical case with a literature review
Nunes, Carlos Eduardo Nogueira; Morais , Anne Diolina Araújo; Lima, João Victor Morais de; Chaves, Filipe Nobre; Sampieri, Marcelo Bonifácio da SilvaPeripheral odontogenic myxoma (POM) is a rare and extra-osseous variant of odontogenic myxoma (OM), classified as a relatively rare benign odontogenic tumor, yet presenting locally aggressive behavior. The objective this manuscript is to report a case of POM in a 75-year-old patient, located in the right maxilla, and in addition, to perform a literature review of the data in relation to clinical, radiographic a...
Uncommon involvement of multiple lesions in the oral cavity: A case report
Vasconcelos Melo, Thiago; Fernandes , Jefferson Douglas Lima; Oliveira, Denise Hélen Imaculada Pereira; Sampieri, Marcelo Bonifácio da SilvaIn maxillomandibular complex lesions of various etiolopathogenesis may occur. Commonly, lesions are solitary, however, in in rare cases, multiple lesions with distinct natures affect the maxillo-mandibular complex. Until now, the recent literature, there are no reports of simultaneous impairment of periapical cysts, dentigerous and cementoblastoma in the same patient. We report the case of a 38-year-old with sy...

Estudo da via PI3k/AKT e da perda de Heterozigosidade do gene supressor tumoral...
Chaves, Filipe NobreOral Potentially Malignant Lesions (PML) is a group of lesions that present a risk for the development of Oral Squamous Cell Carcinoma (OSSC), including Oral Epithelial Dysplasia (OED). PTEN is a tumor suppressor gene of the PI3K / AKT pathway, which is one of the more deregulated pathways of cancer. However, it is still unknown how this pathway is involved in the malignant transformation process of PML. The he...
Immunohistochemical evaluation of GLUT-3 and GLUT-4 in oral epithelial dysplasi...
Feitosa, Sthefane Gomes; Viana, Khalil Fernandes; Luna, Ealber Carvalho Macedo; Costa, Fábio Wildson Gurgel; Cavalcante, Roberta BarrosoObjectives: To evaluate immunohistochemically the expression of GLUT-3 and GLUT-4 in oral epithelial dysplasia (OED) and the oral squamous cell carcinoma (OSCC) and assess possible involvement in the malignant transformation of oral lesions. Methods: Tissue samples of 15 cases of OSCC and 15 of OED were subjected to immunohistochemistry with anti-GLUT-3 and anti-GLUT-4 antibodies. Five fields of each case were ...

Carvalho, Francisco Samuel Rodrigues; Chaves, Filipe Nobre; Soares, Eduardo Costa Studart; Pereira, Karuza Maria Alves; Ribeiro, Thyciana RodriguesElectronic presentations have become useful tools for surgeons, other clinicians and patients, facilitating medical and legal support and scientific research. Microsoft(R) PowerPoint is by far and away the most commonly used computer-based presentation package. Setting up surgical clinical cases with PowerPoint makes it easy to register and follow patients for the purpose of discussion of treatment plan or scie...

Chaves, Filipe Nobre; Marinho, Thâmara Manoela Bezerra; Silva, Paulo Goberlânio de Barros; Oliveira, Francisco Artur Forte; Sousa, Fabrício BituOBJECTIVES: To evaluate the expression of p-AKT, p-JNK, FoxO3a and KI-67 in samples of Oral Squamous Cell Carcinoma (OSCC) and Oral Epithelial Dysplasias (OEDs) to understand their possible involvement in the malignant transformation process of oral lesions. MATERIALS AND METHODS: Tissue samples of 20 cases of OSCCs, 20 OEDs and normal oral mucosa were subjected to immunohistochemistry reactions for anti-p-Akt,...
