Resumo O objetivo desse estudo foi avaliar o perfil clínico-demográfico dos casos de carcinoma de células escamosas oral (CCEO) oral registrados em um centro de diagnóstico bucal no Sul do Brasil. Oitocentos e seis indivíduos com CCEO de 1959 a 2012 foram incluídos no estudo. As variáveis coletadas foram: sexo, idade, ocupação de acordo com o ambiente de trabalho, consumo de álcool e tabaco, cor de pele, localização do tumor, tipo histológico, aparência clínica, tamanho, tempo de evolução, presença de dor e metástase linfonodal. Foi realizada análise descritiva e as associações entre as variáveis foram avaliadas usando qui-quadrado e teste exato de Fisher, com nível de confiança de 5%. CCE oral foi mais comum em homens (76,6%), entre 51 e 70 anos de idade (53,9%). Os sítios mais frequentes foram vermelhão de lábio inferior (23,3%), língua (20,2%) e gengiva/rebordo alveolar (18,1%). Houve uma forte associação entre ocupação em ambiente externo e cor de pele branca com CCEO em lábio. Lesões intraorais de CCEO foram comumente mais dolorosas, maiores que 2 cm e apresentaram metástase linfática. Em conclusão, a maioria dos resultados confirma os dados da literatura em relação a sexo, idade, localização do tumor e ocupação. Além disso, as correlações positivas entre CCE em lábio e ocupação, entre CCEO em lábio e cor de pele branca, e entre lesões maiores e presença de dor/metástase cervical também corroboram os dados da literatura.

Abstract The aim of this study was to evaluate the demographic and clinical profile of the oral squamous cells carcinoma (OSCC) cases registered in a center of oral diagnosis in southern Brazil. Eight hundred and six individuals with OSCC from 1959 to 2012 were included in this study. The variables recorded were: sex, age, occupation according to workplace, alcohol and tobacco consumption, skin color, tumor location, histological type, clinical appearance, size, evolution time, presence of pain and lymph node metastasis. Descriptive analysis was performed and the associations between variables were assessed using the chi-square and Fisher’s exact test, with a confidence level of 5%. OSSC was more common in males (76.6%) aged between 51 to 70 years (53.9%). The most frequent sites were lower lip vermilion (23.3%), tongue (20.2%) and gingiva/alveolar ridge (18.1%). There was a strong association between outdoor occupation and white skin color with lip squamous cell carcinoma (LSCC). OSCC intraoral lesions were commonly more painful, larger than 2 cm and presented lymphatic metastasis. In conclusion, most of the results confirm the data from literature about sex, age, tumor location and occupation. Moreover, the positive correlations between LSCC and occupation, between LSCC and white skin color, and between bigger lesions and presence of pain/cervical metastasis also corroborate the literature data.

OBJECTIVE: Actinic cheilitis (AC) is a precancerous lesion of the lip vermillion caused by prolonged exposure to ultraviolet light. The aim of this study was to evaluate the effect of 3% diclofenac in 2.5% hyaluronic acid gel in the treatment of AC. METHODS: Thirty-four patients with chronic AC were treated twice a day with topical diclofenac during a period of 30 to 180 days. The individuals were followed up every 15 days by means of clinical examination and digital photographic documentation. RESULTS: Of the 27 patients that completed the study, 12 (44%) showed complete remission of the whitish plaques and exfoliative areas, and 15 (56%) had partial remission of the clinical picture of cheilitis. The latter group was submitted to excision of the leukoplakic areas which diagnosis varied from mild to moderate epithelial dysplasia. CONCLUSIONS: The results suggest a promising role for diclofenac in hyaluronic acid gel in the treatment of AC. This treatment has the advantages of not being invasive and showing few side effects.

Despite the large number of published cases about oral and maxillofacial pediatric lesions, the literature is scarce on epidemiological studies regarding the prevalence of these entities. This study retrieved oral and maxillofacial pediatric lesions from the Center of Diagnosis of Oral Diseases (CDDB) at the Dental School of the Federal University of Pelotas (UFPEL), comprising a 20-year period (1983-2002). From the total of 9,465 biopsies received in this period, 625 (6.6%) were from children aged 0 to 14 years. Regardless of the histopathological diagnosis, patient data referring to lesion location, sex and age were collected. Diagnoses were grouped in 13 categories. As much as 89% of the cases occurred in patients aged 7 to 14 years (53% in females and 47% in males). Mucocele (17.2%) was the most common type of lesion, followed by dentigerous cyst (8.6%). In the category of odontogenic tumors, odontoma was the most frequent lesion (64.2%). Malignant lesions were observed in a small section of the sample (1.2%). Generally, the results of the present study are in line with those reported in the literature concerning the most prevalent lesions in the pediatric population. Most lesions were benign, and malignant lesions were diagnosed in a very small part of the sample.
