Saúde bucal de crianças com microcefalia associada ao Zika vírus / Oral health of children with microcephaly associated with Zika vírus / Salud bucal de los niños con microcefalia asociada al virus del Zika

Objetivo: descrever sobre as condições bucais das crianças com Microcefalia associada ao Zika vírus. Metodologia: Estudo transversal realizado com 13 crianças atendidas no projeto institucional e multidisciplinar "Atenção Integrada às crianças com microcefalia por Zika vírus" e seus respectivos cuidadores. Foi realizado entrevista com os cuidadores e de exame clínico bucal nas crianças, sendo coletados dados sobre características sociodemográficas e econômicas, hábitos de higiene, comportamentais e alimentares, assim como as características oclusais e os índices clínicos odontológicos (ISG, IPV e ceo-d). Os dados foram analisados de maneira descritiva e através do teste Wilcoxon no software Statistical Package for the Social Sciences, versão 20. Resultados: A maioria das crianças eram do sexo feminino (53,8%), entre 24 e 35 meses (76,9%) e a mãe era o principal cuidador (76,9%). Em relação aos hábitos das crianças, 61,5% apresentavam alimentação semissólida, com frequência de escovação diária de duas vezes ou mais (46,2%), utilizavam mamadeira (76,9%) e chupeta (53,8%). As crianças não apresentavam cárie, o ISG e IPV foram considerados satisfatórios. Além disso, 92,3% das crianças rangiam os dentes durante a noite, 61,5% apresentavam mordida aberta anterior, sobressaliência aumentada (84,6%) e cronologia de erupção alterada (84,6%). Conclusão: As crianças apresentavam erupção dentária tardia, presença de facetas de desgastes, chave de canino com classificação I, mordida aberta anterior e sobressaliência aumentada. Além disso, possuíam frequência de escovação satisfatória, alimentações semissólida, usavam mamadeira e chupeta. A partir dos índices odontológicos, observou-se que as crianças apresentavam uma saúde bucal satisfatória(AU)

Objective: to describe the oral conditions of children with microcephaly associated with Zikavirus. Methodology: Cross-sectional study carried out with 13 children assisted in the institutional and multidisciplinary project "Integrated Care for children with microcephaly due to Zika virus" and their respective caregivers. Interviews were conducted with caregivers and a clinical oral exam was carried out on the children, with data on sociodemographic and economic characteristics, hygiene, behavioral and dietary habits, as well as occlusal characteristics and clinical dental indexes (ISG, IPV and ceo-d) being collected. The data were analyzed descriptively and using the Wilcoxon test in the Statistical Package for the Social Sciences software, version 20. Results: Most children were female (53.8%), between 24 and 35 months (76.9 %) and the mother wasthe main caregiver (76.9%). Regarding the children's habits, 61.5% had a semi-solid diet, with a daily brushing frequency of twice or more (46.2%), used a bottle (76.9%) and pacifier (53.8%). The children did not present caries, the ISG and IPV were considered satisfactory. In addition, 92.3% of children gritted their teeth at night, 61.5% had an open anterior bite, increased overjet (84.6%) and altered rash chronology (84.6%) Conclusion: Children had a rash late dental, presence of wear facets, canine keywith classification I, anterior open bite and increased overjet. In addition, they had a satisfactory brushing frequency, semi-solid food, used a bottle and used a pacifier. From the dental indexes, it was observed that the children had satisfactory oral health(AU)

Resultados: La mayoría de los niños eran mujeres (53,8%), entre 24 y 35 meses (76,9%) y la madre era la principal cuidadora. (76,9%). En cuanto a los hábitos de los niños, el 61,5% tenía alimentación semisólida, con una frecuencia de cepillado diario de dos o más (46,2%), utilizaba biberón (76,9%) y chupete (53,8%). Los niños no presentaron caries, la ISG y la IPV se consideraron satisfactorias. Además, el 92,3% de los niños apretaban los dientes por la noche, el 61,5% tenía una mordida anterior abierta, un resalte elevado (84,6%) y una cronología de la erupción alterada (84,6%) Conclusión: los niños tenían una erupción dental tardía, presencia de facetas de desgaste, canino clave con clasificación I, mordida abierta anterior y resalte aumentado. Además, tenían una frecuencia de cepillado satisfactoria, alimentos semisólidos, usaban biberón y usaban chupete.

Graded changes in enamel component volumes resulted from a short tooth bleaching procedure.

AIM: To test the hypothesis that changes in enamel component volumes (mineral, organic, and water volumes, and permeability) are graded from outer to inner enamel after a short bleaching procedure. MATERIALS AND METHODS: Extracted unerupted human third molars had half of their crowns bleached (single bleaching session, 3 × 15 min), and tooth shade changes in bleached parts were analyzed with a spectrophotometer. Ground sections were prepared, component volumes and permeability were quantified at histological points located at varying distances from the enamel surface (n=10 points/location), representing conditions before and after bleaching. RESULTS: Tooth shade changes were significant (p<0.001; 95% CI=-1/-8; power=99%), and most of the enamel layer was unaffected after bleaching, except at the outer layers. Multiple analysis of covariances revealed that most of the variance of the change in enamel composition after bleaching was explained by the combination of the set of types of component volume (in decreasing order of relevance: mineral loss, organic gain, water gain, and decrease in permeability) with the set of distances from the enamel surface (graded from the enamel surface inward) (canonical R(2)=0.97; p<0.0001; power>99%). CONCLUSIONS: Changes in enamel composition after a short bleaching procedure followed a gradient within component volumes (mineral loss>organic gain>water gain>decrease in permeability) and decreased from the enamel surface inward.
