Epithelial-myoepithelial carcinoma was first described by Danath et al. in 1972 and is classified as a rare low-grade biphasic neoplasm of the salivary glands. This case report presents a male patient who had a lesion in the oral mucosa with a history of recurrence of the tumor. The outcome resulted in a profile consistent with an epithelial-myoepithelial carcinoma with a high degree of transformation. The case highlights the importance of histopathological evaluation of oral lesions, which occasionally may not present typical clinical aspects of malignant lesion.

ResumoObjetivo: Realizar um estudo bibliométrico dos resumos da SBPqO, traçando um perfil dos trabalhos publicados. Material e métodos: Realizou-se um estudo descritivo, analisando os resumos publicados em anais do referido evento. Os trabalhos foram classificados de acordo com ano de publicação; região; estado; instituição; tipo de instituição; objeto, área ou assunto estudado; tipo de estudo; caracterização do estudo; citação de submissão ao Comitê de Ética e Pesquisa; financiamento para realização da pesquisa; agência/órgão de fomento. A coleta foi realizada por três examinadores, que organizaram os resultados em um banco informatizado. Resultados: De um total de 8.381 resumos, 743 (8,86%) foram referentes à área endodôntica, sendo a maioria desenvolvida na região sudeste (66,1%), principalmente no estado de São Paulo (47%). Como assunto mais pesquisado destacou-se "limas, materiais e instrumentos", com 47,6%. Observou-se maior quantidade de estudos experimentais (66,1%), sendo os do tipo in vitro mais presentes (64,3%). A maioria das pesquisas foi advinda de instituições públicas (73,8%), principalmente de duas instituições específicas: USP com 14,8% e da UNESP com 13,5% dos trabalhos. Percebeu-se, ainda, uma grande quantidade de estudos realizados sem auxílio financeiro (68,5%). Não houve citação de submissão ao Comitê de Ética e Pesquisa. Conclusão: Constatou-se que existe o interesse científico pela área endodôntica mesmo que em pequena escala. Ao mesmo tempo, observou-se a necessidade de maior incentivo às pesquisas em alguns locais, visto que houve concentração em determinadas regiões e instituições, bem como uma diminuição das pesquisas ao considerar-se os anos analisados. Descritores: Pesquisa em Odontologia; Bibliometria; Endodontia. AbstractObjective: This study aimed to perform a comparative analysis of self-perception, the behaviors and attitudes of oral health and the oral health status of adult patients treated at the clinics of the Dentistry Graduate Course from the Dentristy Department of the Federal University of Rio Grande do Norte -UFRN. Methods: A sample of 36 patients was evaluated by applying a questionnaire about self-perception and oral hygiene habits, besides the evaluation of oral health status based on clinical examination data and obtaining the oral indices such as DMF, IVP and IGB. The Data was analyzed using descriptive statistics. Results: It was observed that 94.4% of patients reported having a poor oral health and only 5.6% believed they had adequate oral health. It was found that 41.7% of patients showed low DMFT and 21 (58.3%) high DMFT. A significant proportion of patients (61.8%) felt that having a poor oral health showed high DMFT. Most of the sample felt that having a poor gum health and VPI had a high moderate to severe degree of gingival inflammation. Conclusion: There was a correlation between selfrated oral health and oral clinical conditions of the population evaluated. The results suggest that self-perception of oral health may represent a useful tool in dentistry ...

Nodular fasciitis is a benign, idiopathic, reactive proliferation of myofibroblasts found in the subcutaneous fascia; intraoral occurrence is very rare. An 18-year-old woman was referred to the oral diagnosis service with a 1-month history of a nodular mass in the gingiva. Clinical examination disclosed a wellcircumscribed, mobile, pedunculated mass in the left mandibular gingiva. The clinical diagnoses included pyogenic granuloma. She underwent an excisional biopsy under local anesthesia through an intraoral approach. Microscopic examination showed a proliferation of spindle cells arranged in intersecting fascicles. The spindle cells exhibited plump, vesicular nuclei without significant pleomorphism. Scattered multinucleated giant cells also were present. Immunohistochemical stains showed that the lesional cells were positive for smooth muscle actin and vimentin and negative for S-100 protein. The features were those of an inflammatory, benign myofibroblastic lesion, consistent with intraoral nodular fasciitis. Ó
