M?todos: A elabora??o do instrumento MIS-EC foi dividida em duas etapas: desenvolvimento e valida??o. Na etapa de desenvolvimento, 15 pesquisadores, 30 pais/cuidadores de crian?as com m? oclus?o e 30 pais/cuidadores de crian?as sem m? oclus?o avaliaram a relev?ncia de cada quest?o de um conjunto de 22 itens pr?-selecionados. A partir dos escores padronizados, as quest?es mais relevantes foram inclu?das no instrumento final. O MIS-EC foi, ent?o, aplicado a uma mostra de 230 pais para avaliar a validade discriminante (regress?o de Poisson), validade convergente (correla??o de Spearman) e a consist?ncia interna do instrumento (atrav?s do ?ndice Alpha de Cronbach). A an?lise de confiabilidade teste-reteste foi realizada em uma amostra de 20 pais usando o kappa ponderado para as vari?veis ordinais e o coeficiente de correla??o intraclasse (CCI) para os escores das se??es (crian?a e fam?lia) e o escore total do instrumento. Resultados: Os escores do MIS-EC (total e das se??es da crian?a e da fam?lia) apresentaram signific?ncia estat?stica com a avalia??o da sa?de bucal global e o bem-estar geral da crian?a. Crian?as com m? oclus?o apresentaram 5,68 vezes maior preval?ncia de MIS-EC ? 1 do que crian?as sem m? oclus?o, independentemente da presen?a de c?rie dent?ria e traumatismo. Os valores de Alpha de Cronbach para o escore total, impacto da crian?a e impacto da fam?lia do MIS-EC, foi de 0,85; 0,82 e 0,51, respectivamente. O coeficiente de correla??o intraclasse (ICC) para a confiabilidade do teste-reteste foi de 0,97. Conclus?o: O MIS-EC foi v?lido e confi?vel para a avalia??o do impacto das m?s oclus?es na qualidade de vida de crian?as pr?-escolares e suas fam?lias. Entretanto, s?o necess?rios mais estudos, realizados em outras popula??es, para o melhor estabelecimento das caracter?sticas t?cnicas do instrumento. / Disserta??o (Mestrado) ?

Methods: The elaboration of MIS-EC was split in two stages: development and testing. In the development stage fifteen researchers, thirty parents/caregivers of children with malocclusion and thirty parents/caregivers of children without malocclusion evaluated the relevance of each question from a from a pool of 22 pre-selected items. To identify the most important questions for the composition of the final instrument, the standardized scores were obtained for each item. The MIS-EC was then administered to a sample of 230 parents to evaluate the discriminant validity (Poisson regression), convergent validity (Spearman?s correlation) and internal consistency (using Cronbach?s alpha). The analysis of test-retest reliability was performed on a sample of 20 parents using the weighted kappa for ordinal variables, and intraclass correlation coefficient (ICC) for scores of sections (child and family) and for the total score of the MIS-EC. Results: MIS-EC scores (total score, child?s section score and family?s section score) were statistically significant in assessing the child?s overall oral health and general well-being. Children with malocclusion had 5.68 times higher prevalence of MIS-EC ? 1 than children without malocclusion, regardless of the presence of dental caries and dental trauma. Cronbach's alphas for the total MIS-EC score, the child and family sections were respectively 0.85, 0.82 and 0.51. The intraclass correlation coefficient (ICC) for test-retest reliability was 0.97. Conclusions: The MIS-EC performed well in assessing malocclusions? impacts on OHRQoL among children and their families. Studies in other populations are needed to further establish the instrument's technical properties.

No entanto, h? poucas evid?ncias sobre a influ?ncia de problemas bucais no bem-estar biopsicossocial de pr?-escolares e suas fam?lias, sobretudo comparando aqueles que vivem em zonas urbanas e rurais. O objetivo deste estudo foi avaliar os fatores determinantes da qualidade de vida relacionada ? sa?de bucal (OHRQoL) de crian?as pr?-escolares e suas fam?lias residentes em zona urbana e em zonas rurais de extrema pobreza. Foi realizado um estudo transversal com 391 crian?as, entre dois e cinco anos de idade, das zonas urbana e rural de Diamantina/MG, selecionadas aleatoriamente durante a Campanha Nacional de Vacina??o Infantil. Os pais das crian?as responderam ? vers?o brasileira do Early Childhood Oral Health Impact Scale (B-ECOHIS) e forneceram dados socioecon?micos. Exames cl?nicos das crian?as foram realizados para avaliar c?rie dent?ria, defeitos de desenvolvimento de esmalte, fluorose dent?ria, les?es ou varia??es de normalidade da mucosa bucal e m? oclus?o. An?lise estat?stica envolveu an?lise descritiva, teste de Mann-Whitney, teste do qui-quadrado e regress?o linear m?ltipla. O n?vel de signific?ncia estabelecido foi de 5%. Os valores m?dios do ECOHIS para cada condi??o bucal avaliada foram: c?rie dent?ria 4.52 (DP=6.84), defeitos de desenvolvimento de esmalte 3,82 (DP=6,86), fluorose dent?ria 4,56 (DP=7,53), les?es ou varia??es da normalidade da mucosa bucal 2,84 (DP=5,46) e m? oclus?o 2,16 (DP=4,56). Diferen?as significativas foram encontradas entre o local de resid?ncia e: g?nero (P = 0,008), n?mero de filhos (P = 0,001) e defeitos de desenvolvimento de esmalte (P = 0,035). Fam?lias da zona rural apresentaram valores significativamente inferiores nos aspectos socioecon?micos (P < 0,005), quando comparadas ? fam?lias da zona urbana. Na zona urbana, foram encontradas associa??es significativas entre impacto na OHRQoL e: idade da crian?a em meses (P = 0,004), g?nero (feminino) (P = 0,034), n?mero de dentes cavitados (P < 0,001) e presen?a de defeitos de desenvolvimento de esmalte (P = 0,004). Na zona rural foi encontrada associa??o significativa somente entre impacto na OHRQoL e n?mero de dentes cavitados (P <0,001). Problemas bucais como c?rie dent?ria e defeitos de desenvolvimento de esmalte afetaram negativamente a qualidade de vida de crian?as pr?-escolares e suas fam?lias. Na zona urbana, o n?mero de dentes cavitados, defeitos de desenvolvimento de esmalte, al?m da idade e g?nero (feminino) contribu?ram para diminui??o da qualidade de vida das crian?as pr?-escolares e suas fam?lias. Na zona rural, somente o n?mero de dentes cavitados comprometeu significativamente a vida di?ria dos pr?-escolares e suas fam?lias. / Disserta??o (Mestrado) ?

However, there is little evidence about the influence of oral health problems on biopsychosocial well-being of preschool children and their families, especially comparing those living in urban and rural areas. The aim of this study was to assess the determinants of oral health-related quality of life (OHRQoL) of preschool children and their families living in urban and rural areas of extreme poverty. A cross-sectional study was conducted with 391 children between two and five years of age, from urban and rural areas in Diamantina/MG randomly selected during the National Immunization Campaign. The children's parents answered the Brazilian version of the Early Childhood Oral Health Impact Scale (B-ECOHIS) and provided socioeconomic data. Clinical examination of the children was conducted to assess dental caries, developmental defects of enamel, dental fluorosis, injury or damage to the oral mucosa and malocclusion. Statistical analysis involved descriptive analysis, Mann-Whitney test, chi-square test and multiple linear regression. Significance level was set at 5%. The mean ECOHIS total scores for each oral condition were: dental caries 4.52 (SD = 6.84), developmental defects of enamel, 3.82 (SD = 6.86), dental fluorosis 4:56 (SD = 7.53), injury or oral mucosa lesions 2.84 (SD = 5.46) and malocclusion 2.16 (SD = 4.56). Significant differences were found between place of residence and: gender (P = 0.008), number of children (P = 0.001) and developmental defects of enamel (P = 0.035). Families from rural area had significantly lower socioeconomic aspects (P <0.005), when compared to families from urban area. In urban areas, significant associations were found between the impact on OHRQoL and children's age in months (P = 0.004), gender (female) (P = 0.034), number of cavitated teeth (P <0.001) and presence of developmental defects of enamel (P = 0.004). In rural areas significant association was found only between the impact on OHRQoL and the number of cavitated teeth (P <0.001). Oral health problems such as dental caries and developmental defects of enamel negatively affected the quality of life of preschool children and their families. In the urban area, number of cavitated teeth, developmental defects of enamel, in addition to age and gender contributed to decreased quality of life of preschool children and their families. In rural areas, only the number of cavitated teeth impaired significantly the daily lives of preschool children and their families.
