Abstract The aim of this multicenter study was to explore the early-life sugar consumption and dietary practices in Latin America as well as to investigate the association between breastfeeding duration and the age at which foods and beverages with added sugars are introduced. A cross-sectional study was conducted with 805 1- to 3-year-old children from 10 Latin American countries, as a complementary study to the Research Observatory for Dental Caries of the Latin American Region (OICAL). A Food Frequency Questionnaire previously tested in different countries was applied to children’s mothers and data on breastfeeding and age at introduction of sugary foods and beverages was collected. Statistical analysis included the Kruskal-Wallis test and Poisson regression with robust variance, with the calculation of crude and adjusted mean ratios (MR) and 95% of confidence intervals (CI). The average age at introduction of sugary foods and beverages was 10.1 months (95%CI 9.7–10.4) and 9.6 (95%CI 9.2–9.9) months, respectively, with a significant variation between countries (p < 0.001). The average daily frequency of sugary foods-beverages was 3.3 times per day (95%CI 3.1–3.5) and varied significantly between countries (p = 0.004). Breastfeeding duration of over six months was associated with an increase in the age of introduction of sweet drinks (16%; MR 1.16; 95%CI 1.05–1.28) and foods (21%; MR 1.21; 95%CI 1.10–1.33). In conclusion, most children from vulnerable settings in Latin America start consuming sugary products in the first year of life and a high frequency of consumption was reported through early childhood. Additionally, breastfeeding contributes to a delay in the introduction of sugary products.

Resumen Este trabajo tiene como objetivo relatar el abordaje individualizado, inclusivo y humanizado de un niño de 4 años y tres meses, con diagnóstico de neurofibromatosis tipo 1, atendido en la Carrera de Especialización en Odontopediatria de la Escuela de Graduados, Facultad de Odontologı́a, Universidad de la República, Montevideo, Uruguay. En el examen clínico se pudo observar cicatrices derivadas del tratamiento quirúrgico del neurofibroma plexiforme en la zona cervical y la presencia de hipotonicidad muscular oral. Al examen clínico intraoral, se observaron amplias zonas desdentadas a consecuencia de exodoncias de quince dientes deciduos. Presentaba lesiones activas de caries en los dientes remanentes, acompañado de biopelícula generalizada y sangrado gingival provocado. Se realizó un abordaje integral del paciente y la terapia rehabilitadora mediante el uso de prótesis parcial removible superior e inferior. Concluímos que el tratamiento odontológico educativo, preventivo, restaurador y rehabilitador fue satisfactorio y la empatı́a, como proceso dinámico, involucró mecanismos cognitivos, afectivos y conductuales, y fue reconocida por sus efectos positivos en la promoción de la salud bucal del paciente.

Abstract This paper aims to report an individualized, inclusive, and humanized dental approach, emphasizing the importance of treating a child aged four years and three months with neurofibromatosis type 1. The patient was referred and treated at the Clinic of the Specialization Course in Pediatric Dentistry of the Graduate School, School of Dentistry, Universidad de la República, Montevideo, Uruguay. The clinical examination revealed scars from the surgical treatment of the plexiform neurofibroma and neck and oral muscle hypotonicity. The intraoral clinical examination showed large edentulous areas as 15 deciduous teeth were missing. The patient had active carious lesions, generalized microbial biofilm on the tooth surfaces, and gingival bleeding. A comprehensive treatment was provided, as well as restorative therapy with upper and lower removable partial dentures. We conclude that the dental educational, preventive, restorative, and rehabilitation treatment was satisfactory. Furthermore, empathy, as a dynamic process, involved cognitive, affective, and behavioral mechanisms. It also helped enhance the patient’s oral health.

Resumo Avaliar o impacto das condições bucais na qualidade de vida relacionada à saúde bucal (QVRSB) em crianças de dez países da América Latina (AL). Foi realizado um estudo transversal com 930 pares de crianças/pais de 1 a 3 anos de 10 países da AL, como estudo complementar do Research Observatory for Dental Caries of the Latin American Region. A escala ECOHIS, previamente testada e validada em dez países, foi aplicada a pais/cuidadores de crianças para mensurar a QVRSB. A análise estatística incluiu análise descritiva de dados e análise de variância unidirecional (ANOVA-One-Way) para comparar grupos etários com QVRSB. Procedimentos de bootstrapping (1000 reamostragens; 95%IC Bca) foram realizados. A pontuação média da seção 'Impacto na Criança' na AL foi 4,0 (±8,3), na seção ‘Impacto na Família’ foi 2,0 (±4,0) e no escore total do ECOHIS foi 6,0 (±12,0). Na seção 'Impacto na Criança', Argentina 10,0(+2,4) e Venezuela 17,8(±17,5) demonstraram pontuações médias superiores aos dados totais da AL. Na seção ‘Impacto na Família’, os países com pontuações médias mais altas foram Argentina 4,9(±2,0), Equador 2,1(±3,1) e Venezuela 7,9(±7,8). No escore total do ECOHIS, Argentina 15,1 (±4,1) e Venezuela 25,7(±25,2) apresentaram escores médios superiores aos valores de AL. Houve associação entre a idade das crianças e o relato dos pais de impacto na QVRSB (p<0,001). As crianças de três anos tiveram média maior quando comparadas às de um e dois anos, tanto nas seções 'Impacto na Criança' e ‘Impacto na Família’ (p<0,001), quanto no escore total ECOHIS (p<0,001). Em conclusão, houveram diferenças na QVRSB entre os países da América Latina, impactando de forma mais significativa as crianças mais velhas.

Abstract To assess the impact of oral conditions on oral health-related quality of life (OHRQoL) in infants in ten Latin America countries (LAC). A cross-sectional study was conducted with 930 pairs of 1-to-3-year-old children/parents from 10 LAC, as a complementary study of the Research Observatory for Dental Caries of the Latin American Region. The scale ECOHIS, previously tested and valid in ten countries, was applied to parents/caregivers of children to measure OHRQoL. Statistical analysis included descriptive data analysis and one-way analysis of variance (ANOVA-One-Way) were performed to compare age groups with OHRQoL. Bootstrapping procedures (1000 re-samplings; 95%CI Bca) were performed. The mean scores of the ‘Child Impact’ section in the LAC was 4.0(±8.3), in the ‘Family Impact’ section was 2.0(±4.0), and in overall ECOHIS score was 6.0(±12.0). In the ‘Child Impact’ section, Argentina 10.0(+2.4) and Venezuela 17.8(±17.5) demonstrated mean scores higher than the LAC total data. In the ‘Family Impact’ section, the countries with higher mean scores were Argentina 4.9(±2.0), Ecuador 2.1(±3.1) and Venezuela 7.9(±7.8). In the overall ECOHIS score, Argentina 15.1 (±4.1) and Venezuela 25.7(±25.2) has higher mean scores than the values of LAC. There is an association between children's age and parents' report of impact on the OHRQoL (p<0.001). Three-year-olds had a higher mean when compared to one- and two-year-olds, both in the Impact on the Child and Impact on the Family (p<0.001) sections, as well as in the overall ECOHIS (p<0.001). In conclusion, there are differences in OHRQoL among Latin American countries, impacting older children more significantly.

RESUMO Objetivo O objetivo deste estudo foi avaliar a disponibilidade e a estabilidade da fração solúvel de flúor nos dentifrícios fluoretados comercialmente disponíveis no Uruguai. Métodos Quatorze dentifrícios fluoretados de quatro diferentes fabricantes foram analisados. Análises randomizadas e cegas foram realizadas em duplicata para cada dentifrício no momento da aquisição (amostras frescas) e depois de 12 meses de armazenamento em temperatura ambiente (amostras envelhecidas). As concentrações de flúor total e flúor solúvel total foram determinadas usando um eletrodo específico para flúor. Resultados As concentrações de flúor total de todos os produtos testados foram menores do que os níveis de flúor especificados pelos fabricantes. Os valores das frações de flúor solúvel total foram menores do que as concentrações de flúor total nas amostras frescas de cinco dentifrícios e nas amostras envelhecidas de 10 dentifrícios (p < 0.05). Três dentifrícios apresentaram as frações de flúor solúvel total insuficientes e instáveis (< 60%) e cinco dentifrícios tiveram apenas frações instáveis de flúor solúvel total (<1000 ppm) após 12 meses. Conclusão Baseado nosresultados deste estudo pode-se concluir que dos quatorze dentifrícios fluoretados comercialmente disponíveis no Uruguai analisados neste estudo, três produtos apresentaram insuficientes e instáveis frações quimicamente ativas de flúor e cinco outros dentifrícios tiveram falta de estabilidade o que pode comprometer suas eficácias. É necessário revisar as orientações sobre dentifrícios fluoretados no Uruguai a fim de garantir um benefício ótimo para a população.

ABSTRACT Objective The aim of this study was to evaluate the availability and stability of soluble fluoride fraction in commercial fluoride toothpastes available in Uruguay. Methods Fourteen fluoride toothpastes from four different manufacturers were analyzed. Randomized and blinded analyses were performed in duplicate for each dentifrice at the time of purchase (fresh samples) and after 12 months of storage at room temperature (aged samples). Total fluoride and total soluble fluoride concentrations were measured using a fluoride specific electrode. Results Total fluoride concentrations in all of the products were lower than the F levels specified by the manufacturers. Total soluble fluoride fractions were lower than the total fluoride concentrations in fresh samples of five toothpastes and in aged samples of ten toothpastes (p < 0.05). Three toothpastes had insufficient and unstable total soluble fluoride fractions (< 60%) and five toothpastes had only unstable total soluble fluoride fractions (<1000 ppm) after 12 months. Conclusion Based on theresults of this study, it can be concluded that from fourteen Uruguayan commercial fluoride toothpastes analyzed in this study, three toothpastes have insufficient and unstable chemically active F fractions and five other toothpastes have the lack of stability which may compromise their efficacies. Review the guidelines on fluoride dentifrices in Uruguay is necessary, in order to ensure optimum benefit for population.

El aumento en la prevalencia de hipomineralizaciones del esmalte preocupa a la Odontopediatría. Las lesiones abarcan desde opacidades delimitadas blanco amarillentas o amarronadas hasta la ruptura del esmalte, siempre afectando a los primeros molares e incisivos permanentes. Por tal motivo se define esta patología con el nombre de "Molar Incisor Hipomineralization", lo que motiva el uso internacional de la sigla MIH. Se trata de una lesión de Hipomineralización del esmalte, de origen sistémico y etiología variada que se desarrolla en el primer año de vida del individuo. Se debe hacer el diagnóstico diferencial con hipoplasias del esmalte, fluorosis y amelogénesis imperfecta Las lesiones tienen un significativo impacto en las necesidades de tratamiento, incluso en poblaciones con baja actividad de caries, dificultan las técnicas adhesivas y requieren procedimientos rehabilitadores de alto costo en el adulto. La prevalencia reportada a nivel internacional varía entre 3 y 23.4%, afectando por igual a ambos sexos. En nuestro país son necesarios estudios para determinar su prevalencia.

The increase of the enamel hipomineralizarion prevalence worries pediatric dentistry. It goes from delimited yellowish whited opacities to the rupture of the enamel, always related to the permanent first molars and incisives. It is because this reason that this patology is redefined as "Molar Incisor Hipomineralization", what motives the international use of the term MIH. This is about a hipomineralization enamel lesion, of sistemic origin and complex ethiology which is developed on the first year of the patient’s life. The diagnosys must be done whith different enamel hypoplasia, fluorosis and imperfect amelogenesis This has a significant impact in the treatment necesities even in comunities whith low caries activity which make difficult the adhesive techniques and require expensive rehabilitation processes in adults. It’s prevalence varies between 3 and 23.4% and both sexes are affected equally. In our country studies are needed to determine it’s prevalence.
