Maternal risk behavior and caries incidence in children with sickle cell disease

The aim of this study was to analyze the incidence of caries, in relation to maternal risk behaviors and clinical conditions representing different levels of sickle cell disease severity. A total of 295 children aged 6 to 60 months participated in this cohort conducted from August 2007 to December 2008. They were diagnosed and monitored by the referral service of the state. Interviews were made with families to identify sociodemographic variables, and an oral exam was performed to determine dental caries. The SRQ (Self Report Questionnaire) scale was used to diagnose the presence of common mental disorders, and the CAGE (Cut down, Annoyed, Guilty and Eye opener) was applied to determine abusive use of alcohol. The absolute and relative frequencies of the variables of interest were analyzed by Chi-square and Mann-Whitney, with a 5% significance level. The incidence variables were analyzed according to the logistic regression model, with a confidence interval of 95%. Caries incidence (1.98; SD = 4.68) was higher in the HbSS genotype. There was a statistically significant association between caries incidence and both abusive use of alcohol (32.43%, RR = 1.99; 1.05-3.78; 95%CI) and common mental disorders (8.77% RR = 0.37; 0.15-0.93; 95%CI). There was also an association between caries incidence and maternal risk behavior, indicating that the care network should be expanded to include patients with sickle cell disease.

Condições de saúde bucal e fatores sociodemográficos de crianças de 6 a 96 meses com doença falciforme no Estado da Bahia / Conditions of oral health and socio-demographic factors in children from 6 to 96 months with sickle cell disease of Bahia

Este estudo de corte transversal objetivou analisar de forma descritiva variáveis sociodemográficas e de condições de saúde bucal em 704 crianças de 6 a 96 meses com doença falciforme no Estado da Bahia, entre agosto de 2007 e julho de 2008. A maioria da população era parda (51,70%), gênero masculino (50,5%), média de idade de 32,16 meses (DP = ±17,92), mães com até o Primeiro Grau completo (57,39%) e renda familiar menor que um salário mínimo (42,05%). Os genótipos HBSS e HBSC foram os mais expressivos. Observou-se que as condições de vida dos portadores da doença influenciam bastante a condição de saúde bucal. Os achados apontam a necessidade de planejamento dos serviços de atenção básica para essas crianças, visando à ampliação do atendimento especializado aos portadores da doença no Estado.

This cross-sectional study aimed to analyze descriptively socio-demographic and oral health status variables in 704 children aged 6 to 96 months with a confirmed diagnosis of sickle cell disease between August 2007 and July 2008. The majority of the population was mestizo (51.70%), male sex (50.5%), mean age was 32.16 months (SD = 17.92), mothers until the primary school (57.39%) and family income less than minimum wage (42.05%). Genotypes HBSS and HBSC were the most expressive. It was observed that the living conditions of disease carriers strongly influence the oral health status. The results indicate the need for planning of basic health care for these children, aiming to expand the specialized care to disease carriers in the State.

Estudo "in vitro" da capacidade remineralizante de uma solução artificial em lesões de cárie incipiente / \"In vitro\" study of the remineralization capacity of an artificial solution on incipient carious lesions

Através de incorporação de F e de microscopia de polarização foi demonstrada, no presente trabalho, a reversão de lesões incipientes de cárie dentária, tanto artificiais quanto naturais, usando-se uma solução por nós formulada. A deposição de minerais se inicia nas regiões mais superficiais da lesão, progredindo gradativamente às regiões mais profundas. O tempo de reversão das manchas brancas, depende da extensão da lesão. A solução remineralizante que testamos pode ser uma boa alternativa para reversão de mancha branca
