Mucoceles are benign pseudocystic lesions, whose main etiological factors are trauma and ductal obstruction, with the rupture of a duct in the salivary gland and leakage of mucin into the adjacent soft tissues. They are characterized by being asymptomatic and often present spontaneous rupture. Histologically, they are made up of a cystic wall devoid of epithelium, outlined by granulation tissue and inflammatory cells. Mucoceles usually present as dome-shaped mucous swellings, which can vary in size from 1 to 2 mm to a few centimeters, characterized as a floating lesion, although some may be firm on palpation. The evolution time reported for this lesion varies from a few days to several years, and the most common site of involvement for this phenomenon is the lower lip. Some mucoceles are self-limiting, with spontaneous rupture and scarring, however, many of these lesions are chronic in nature, and local surgical excision may be necessary. The aim of this study was report a clinical case of mucocele on the lower lip. The surgical removal of the mucocele proved to be an effective and safe technique in the case in question, enabling the histopathological diagnosis of the lesion.
Na área odontológica de cirurgia bucomaxilofacial um grande número de casos de dentes não erupcionados e impactados é comumente encontrado nos pacientes atendidos na Faculdade de Odontologia de Araçatuba - UNESP. O objetivo deste estudo foi determinar o perfil dos pacientes e dos terceiros molares indicados para exodontia, assim como seu tratamento cirúrgico. Foram obtidos para a pesquisa o perfil dos pacientes e dos dentes extraídos a partir de tratamentos realizados nas clínicas da faculdade, onde uma ficha foi aplicada para cada dente extraído. A partir das fichas foram obtidos os dados pessoais dos pacientes, a presença ou não de doença sistêmica, classificação de Pell & Gregory e Winter para terceiros molares, se o dente está causando algum transtorno mecânico, nervoso, infeccioso ou tumoral. Consta também preenchimento na ficha para o período pós-operatório se existiu ou não algum tipo de transtorno. Ao longo de três anos foram atendidos 134 pacientes, sendo 57% do sexo feminino e 43% do sexo masculino, tendo a maior procura por atendimento a faixa etária de 20 a 29 anos, totalizando 275 dentes extraídos. Em 54% dos casos foram extraídos molares inferiores, sendo a posição A e a classe II mais prevalentes segundo a classificação de Pell & Gregory. Para todos os terceiros molares extraídos a posição mais frequente foi a vertical com 58% dos casos segundo a classificação Winter. Conclui-se que a maioria dos pacientes são jovens do sexo feminino prevalecendo os procedimentos de exodontia de terceiros molares inferiores. E as complicações pós-operatórias mais frequentes foram o edema, alveolite e parestesia do nervo alveolar inferior.
Odontomas are classified as a malformation where epithelial and mesenchymal cells have the ability to produce dental tissues such as enamel and dentin. Of unknown etiology, they are often associated with failure of eruption of permanent teeth and / or late impaction or exfoliation of deciduous teeth. Surgical removal is the therapeutic option of choice for the treatment of this condition, since its presence can cause some intercurrences as root resorptions of the neighboring teeth. The objective of this case report is to describe a surgical approach for the removal of a composite odontoma in the anterior region of the mandible, where after a 5-year postoperative follow-up, it was possible to observe in radiographic and tomographic analyses, small images of radiopaque characteristic compatible with recurrence tumor, hypercalcification or remnant of the lesion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
