Oral and maxillofacial outcomes in children with microcephaly associated with the congenital Zika syndrome.

INTRODUCTION: The objective of this study is to assess the oral and maxillofacial characteristics of microcephalic children associated with congenital Zika syndrome (CZS). METHODS: A cross-sectional, observational study was carried out with 61 patients with microcephaly/CZS born between June 2015 and September 2017 (29 boys and 32 girls, average age of 22.8 months) and a control group with 58 non-CZS children born in the same period (25 boys and 33 girls, average age of 23.8 months). The functional clinical analysis considered the labial and lingual frena, tongue anterior projection, oral escape, palate form, and first tooth eruption. For the craniofacial analysis, facial anthropometric points and the cephalic perimeter at the time were measured. Demographic data were collected from medical records, and a clinical exam was performed in order to register the intrabuccal characteristics and craniofacial measures. The chi-square test and Student's t-test were used with a significance level of 0.05. RESULTS: The narrow palate form, tongue anterior projection, oral escape, and late first tooth eruption were significantly more present in the group with microcephaly/CZS. As for the craniofacial analysis, face width (Bi-Zi), mandible width (Go-Go), height of face upper third (Tr-G), and monthly growth of cephalic perimeter were significantly smaller, whereas height of face lower third (Sn-Gn) was significantly bigger in the group with microcephaly/CZS (P < 0.05). CONCLUSION: Children with microcephaly resulting from a congenital Zika infection showed functional, oral, and maxillofacial changes and smaller facial development in comparison with non-CZS children in the same age group.

Impact of malocclusion severity on the quality of life of non-white adolescents.

The aim of this study was to evaluate the impact of malocclusion severity on the oral health-related quality of life (OHRQoL) of non-white adolescents. A cross-sectional study was conducted with 585 non-white Brazilian adolescents (12-15 years). The Dental Aesthetic Index (DAI) was used for the clinical assessment of malocclusion and Oral Health Impact Profile (OHIP-14) on OHRQoL. Deep bite and transverse occlusal relationships were assessed in association with the DAI. The adolescents with DAI 3 and 4 were distributed into 4 groups: G1 - individuals without transverse occlusal relationships or deep bite; G2 - individuals with only posterior crossbite; G3 - individuals with only deep bite; and G4 - individuals with Brodie bite. The backward stepwise procedure was used to select variables on each level, eliminating variables with a p≤0.20. From the logistic regression analyses, the adjusted odds ratios were estimated with the respective 95% confidence intervals. The adolescents with severe malocclusion divided into the G2, G3 and G4 showed p-value of 0.0501, 0.1475, and 0.5407, respectively, but did not remain in the final model. Malocclusion severity had no impact on the OHRQoL of non-white adolescents.

Resumo O objetivo deste estudo foi avaliar o impacto da severidade da má oclusão na qualidade de vida relacionada à saúde bucal (OHRQoL) de adolescentes não brancos. Estudo transversal foi realizado com 585 adolescentes brasileiros não brancos (12-15 anos). O Índice de Estética Dental (DAI) foi utilizado para a avaliação clínica da má oclusão e o Oral Health Impact Profile (OHIP-14) na OHRQoL. A sobremordida profunda e as relações oclusais transversais foram avaliadas em associação com o DAI. Os adolescentes com DAI 3 e 4 foram divididos em 4 grupos: G1 - indivíduos com relação transversal normal ou com ausência de sobremordida; G2 - indivíduos com mordida cruzada posterior; G3 - indivíduos com sobremordida profunda; e, G4 - indivíduos com mordida em Brodie. O modelo final estimou as variáveis selecionadas após o ajuste para aquelas que permaneceram no modelo multivariado em níveis iguais e superiores. A partir das análises de regressão logística, os odds ratios foram ajustados e estimados com os respectivos intervalos de confiança de 95%. Os adolescentes com má oclusão severa divididos em G2, G3 e G4 mostraram um p-valor de 0.0501, 0.1475, e 0.5407, respectivamente, mas não permaneceram no modelo final. A severidade da má oclusão não teve impacto na OHRQoL de adolescentes não brancos.

Perfil clínico-demográfico de los carcinomas de células escamosas bucales en una población del nordeste de Brasil / Clinical and demographic profile of oral squamous cell carcinoma in a northeast population of Brazil

Objetivo: Describir el perfil clínico-demográfico e identificar los factores de riesgo presentes en individuos portadores de carcinoma oral de células escamosas, que asistieron a un centro de referencia del nordeste de Brasil, de 2007 a 2015. Materiales y métodos: En este estudio descriptivo y retrospectivo, los datos fueron recopilados de las historias clínicas de individuos con diagnóstico histológico de carcinoma oral de células escamosas. Resultados: De los 104 casos analizados, el 72,12% eran hombres; el 53,84%, mayores de 60 años, y el 38,9%, de tez morena. La mayoría de los individuos eran alcohólicos y/o fumadores (95%). En cuanto a las lesiones, en su mayoría eran: ulceradas (58,70%), rojas (47,42%), de superficie arrugada (92,39%), duras (78,02%), con crecimiento endofítico (56,12%) y estaban localizadas en el borde lateral de la lengua (27,62%). Conclusiones: En este estudio, el carcinoma oral de células escamosas fue diagnosticado principalmente en hombres de tez morena, mayores de 60 años. Las lesiones más frecuentes fueron úlceras en la lengua. El consumo de tabaco y alcohol fueron las características de comportamiento de mayor ocurrencia (AU)
