BACKGROUNDPatients with diabetes mellitus have been associated with a number of changes in the oral cavity, such as gingivitis, periodontitis, mucosal diseases, salivary dysfunction, altered taste, and burning mouth.OBJECTIVESTo determine the prevalence of oral mucosal lesions in patients with diabetes mellitus.METHODSA cross-sectional observational study between August and October 2012 with a convenience sampling was performed for 51 patients with diabetes mellitus (type 1 and type 2). The study consisted of two phases: 1) a questionnaire application; 2) intraoral clinical examination. For the analysis of data, we used descriptive statistics, Fisher's exact test in bivariate analysis (significance level of 0.05), and Poisson Regression.RESULTSThe prevalence of oral lesions was 78.4%. Traumatic ulcers (16.4%) and actinic cheilitis (12.7%) were the most prevalent lesions. The lips (35.3%) and tongue (23.5%) were the most common location. The bivariate analysis showed an association with the type of diabetes, and two variables (age and comorbidity) were quite close to the significance level. In the Poisson Regression analysis, only diabetes type 2 remained significant after adjusting the model.CONCLUSIONSThe results of this study show a high prevalence of oral mucosal lesions in diabetic patients. The oral mucosal lesions are mostly associated with diabetes type 2.

Introduction. Neoplasm of the head and neck can be treated surgically, by radiation, chemotherapy, or using combination of these methods. In contrast to surgical and radiation treatment which mostly have a local effect, chemotherapy in addition to local have also a systemic effect. Both XRT in oral region and chemotherapy can affect oral health. The aim of this study was to assess the oral health status and quality of life in patients with head and neck cancer after receiving radiation therapy. Material and Methods. Quantitative, analytical and cross-sectional research methods along with the application of UW-QOL questionnaire version 4, were used. Seventy one patients of the outpatient facilities at two cancer hospitals in the state of Para?ba, Brazil, were included in the study. Oral health status was evaluated using the Lockhart and Clark criteria. Linear Poisson and Logistic Regression tests were applied to assess associations between the variables using a significance level of 5%. Results. Of the total number of patients, 71.83% were male, the average age was 62 years and 57.74% were non-Caucasian. The group that received dental monitoring and follow-up attained the highest (830.13) Quality of life scores, including: ?pain? (93.13) and ?taste? (83.07). The highest score for oral health in the group that did not receive dental monitoring and follow-up treatment was 4.08 for ?oral hygiene?. Conclusion. Dental monitoring and follow-up should begin before radiation therapy, given that both the illness and methods used for the treatment negatively affect patients? quality of life.

Although the number of reported cases is low, mucoepidermoid carcinoma is the most common malignant salivary gland neoplasm in RESUMOEmbora apresente uma casuística baixa, o Carcinoma Mucoepidermoide é a neoplasia maligna de glândula salivar mais observada na cavidade oral. Possui etiopatogenia desconhecida e, clinicamente, apresenta-se como tumefação sintomática ou não, sendo o palato, o sítio de predileção. Em decorrência da sua grande diversidade biológica, o tratamento e prognóstico dependem do grau histológico, da localização e do estágio clínico do tumor. O presente trabalho teve por objetivo descrever um caso clínico de carcinoma mucoepidermoide de uma paciente do gênero feminino, 45 anos de idade, feoderma. O exame físico intraoral evidenciou, em região retromolar esquerda, bolha de limites nítidos, medindo cerca de 1,0 cm de diâmetro, coloração azulada, presente há aproximadamente quatro meses. Diante do diagnóstico clínico de mucocele, foi realizada a biopsia excisional; durante a execução da mesma, observou-se extravasamento de muco amarelado. Após o resultado anatomopatológico de carcinoma mucoepiderrmoide, a paciente foi encaminhada ao cirurgião de cabeça e pescoço. Desta forma, enfatiza-se a importância do diagnóstico precoce e correto manejo desta patologia, que, mesmo quando sua aparência clínica não sugerir malignidade, deve ser considerada como hipótese diagnóstica em lesões proliferativas da boca.Termos de indexação: Diagnóstico.
