Early-life sugar consumption and breastfeeding practices: a multicenter initiative in Latin America.

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.

Child dental neglect and legal protections: a compendium of briefs from policy reviews in 26 countries and a special administrative region of China.

Background: Child neglect is a public health, human rights, and social problem, with potentially devastating and costly consequences. The aim of this study was to: (1) summarize the oral health profile of children across the globe; (2) provide a brief overview of legal instruments that can offer children protection from dental neglect; and (3) discuss the effectiveness of these legal instruments. Methods: We summarized and highlighted the caries profile and status of implementation of legislation on child dental neglect for 26 countries representing the World Health Organization regions: five countries in Africa (Nigeria, South Africa, Sudan, Tanzania, Zimbabwe), eight in the Americas (Argentina, Brazil, Canada, Chile, Mexico, Peru, Unites States of America, Uruguay), six in the Eastern Mediterranean (Egypt, Iran, Libya, Jordan, Qatar, Saudi Arabia), four in Europe (Italy, Latvia, Serbia, United Kingdom), two in South-East Asia (India and Indonesia) and one country (China) with its special administrative region (Hong Kong) in the Western Pacific. Results: Twenty-five of the 26 countries have legal instruments to address child neglect. Only two (8.0%) of these 25 countries had specific legal instruments on child dental neglect. Although child neglect laws can be interpreted to establish a case of child dental neglect, the latter may be difficult to establish in countries where governments have not addressed barriers that limit children's access to oral healthcare. Where there are specific legal instruments to address child dental neglect, a supportive social ecosystem has also been built to facilitate children's access to oral healthcare. A supportive legal environment, however, does not seem to confer extra protection against risks for untreated dental caries. Conclusions: The institution of specific country-level legislation on child dental neglect may not significantly reduce the national prevalence of untreated caries in children. It, however, increases the prospect for building a social ecosystem that may reduce the risk of untreated caries at the individual level. Social ecosystems to mitigate child dental neglect can be built when there is specific legislation against child dental neglect. It may be more effective to combine public health and human rights-based approaches, inclusive of an efficient criminal justice system to deal with child dental neglect.

Impact on oral health-quality of life in infants: Multicenter study in Latin American countries.

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.

CariesCare International adapted for the pandemic in children: Caries OUT multicentre single-group interventional study protocol.

BACKGROUND: Comprehensive caries care has shown effectiveness in controlling caries progression and improving health outcomes by controlling caries risk, preventing initial-caries lesions progression, and patient satisfaction. To date, the caries-progression control effectiveness of the patient-centred risk-based CariesCare International (CCI) system, derived from ICCMS™ for the practice (2019), remains unproven. With the onset of the COVID-19 pandemic a previously planned multi-centre RCT shifted to this "Caries OUT" study, aiming to assess in a single-intervention group in children, the caries-control effectiveness of CCI adapted for the pandemic with non-aerosols generating procedures (non-AGP) and reducing in-office time. METHODS: In this 1-year multi-centre single-group interventional trial the adapted-CCI effectiveness will be assessed in one single group in terms of tooth-surface level caries progression control, and secondarily, individual-level caries progression control, children's oral-health behaviour change, parents' and dentists' process acceptability, and costs exploration. A sample size of 258 3-5 and 6-8 years old patients was calculated after removing half from the previous RCT, allowing for a 25% dropout, including generally health children (27 per centre). The single-group intervention will be the adapted-CCI 4D-cycle caries care, with non-AGP and reduced in-office appointments' time. A trained examiner per centre will conduct examinations at baseline, at 5-5.5 months (3 months after basic management), 8.5 and 12 months, assessing the child's CCI caries risk and oral-health behaviour, visually staging and assessing caries-lesions severity and activity without air-drying (ICDAS-merged Epi); fillings/sealants; missing/dental-sepsis teeth, and tooth symptoms, synthetizing together with parent and external-trained dental practitioner (DP) the patient- and tooth-surface level diagnoses and personalised care plan. DP will deliver the adapted-CCI caries care. Parents' and dentists' process acceptability will be assessed via Treatment-Evaluation-Inventory questionnaires, and costs in terms of number of appointments and activities. Twenty-one centres in 13 countries will participate. DISCUSSION: The results of Caries OUT adapted for the pandemic will provide clinical data that could help support shifting the caries care in children towards individualised oral-health behaviour improvement and tooth-preserving care, improving health outcomes, and explore if the caries progression can be controlled during the pandemic by conducting non-AGP and reducing in-office time.

An ecological study on the association between universal health service coverage index, health expenditures, and early childhood caries.

BACKGROUND: Universal health care (UHC) may assist families whose children are most prone to early childhood caries (ECC) in accessing dental treatment and prevention. The purpose of this study was to determine the association between UHC, health expenditure and the global prevalence of ECC. METHODS: Health expenditure as percentage of gross domestic product, UHC service coverage index, and the percentage of 3-5-year-old children with ECC were compared among countries with various income levels using one-way analysis of variance (ANOVA). Three linear regression models were developed, and each was adjusted for the country income level with the prevalence of ECC in 3-5-year-old children being the dependent variable. In model 1, UHC service coverage index was the independent variable whereas in model 2, the independent variable was the health expenditure as percentage of GDP. Model 3 included both independent variables together. Regression coefficients (B), 95% confidence intervals (CIs), P values, and partial eta squared (ƞ2) as measure of effect size were calculated. RESULTS: Linear regression including both independent factors revealed that health expenditure as percentage of GDP (P < 0.0001) was significantly associated with the percentage of ECC in 3-5-year-old children while UHC service coverage index was not significantly associated with the prevalence of ECC (P = 0.05). Every 1% increase in GDP allocated to health expenditure was associated with a 3.7% lower percentage of children with ECC (B = - 3.71, 95% CI: - 5.51, - 1.91). UHC service coverage index was not associated with the percentage of children with ECC (B = 0.61, 95% CI: - 0.01, 1.23). The impact of health expenditure on the prevalence of ECC was stronger than that of UHC coverage on the prevalence of ECC (ƞ2 = 0.18 vs. 0.05). CONCLUSIONS: Higher expenditure on health care may be associated with lower prevalence of ECC and may be a more viable approach to reducing early childhood oral health disparities than UHC alone. The findings suggest that currently, UHC is weakly associated with lower global prevalence of ECC.

Dental caries in three-year-old preschool children in Lima, Peru assessed according to the CAST instrument.

The aim of this study was to determine the caries situation of three-year-old preschool children residing in low socioeconomic status districts in Lima, Peru. The study is a crosssectional analysis of the caries situation of suburban areas of Lima. A stratified sampling procedure by geographical distribution, considering healthcare centers with a motherand- child health clinic and surrounding preschools as factors, identified 45 randomly selected preschools, of which 17 accepted to participate. Children from 3-year-old classrooms were examined by two independent calibrated dentists using the Caries Assessment Spectrum and Treatment (CAST) instrument at their premises using artificial light, sterile examination mirrors and gauze for drying each tooth before evaluation. ANOVA and the Tamhane method were used to analyze the data. 308 children, mean age 3.4 years (min: 3 years; max: 3 years, 7 months), were examined. The sample prevalence of enamel and dentine carious lesions (CAST code 3-7) was 91.2% while the prevalence of dentine carious lesions (CAST code 4-7) was 58.8%. The mean number of teeth with cavities that had reached the pulp and those that had an abscess or fistula were 2.0% and 0.5% respectively. The majority of enamel and dentine carious lesions were observed in molars. The CAST severity score was 7.0. Mean examination time was 57 seconds. The burden of dental caries of the children at this young age was high.

Dental caries and oral health-related quality of life of 3-year-olds living in Lima, Peru.

BACKGROUND: Untreated dental caries negatively impacts children and their families; the implication of which is best measured through assessing quality of life. Information related to Oral Health-Related Quality of Life (OHRQoL) in Peruvian pre-school children is scarce. AIM: To investigate the relationship between dental caries and the OHRQoL of 3-year-old children. DESIGN: Randomly selected government pre-schools (n = 17), situated in three low socio-economic status districts in Lima, participated. The OHRQoL data were obtained using the Peruvian (P) ECOHIS questionnaire. Clinical examinations using the Caries Assessment Spectrum and Treatment (CAST) instrument were performed on 308 children. From which, 213 parents returned the P-ECOHIS form. ANOVA, Tamhane, and Tukey methods were used to analyse the data. RESULTS: The mean age of the children was 3.04 years. The two highest mean P-ECOHIS scores in the child section were 'child symptoms' and 'child psychology' while 'parent distress' scored highest in the parent section. The prevalence of dental caries was 64.3% (CAST scores 4-7). Including CASTcode 3 (enamel carious lesion), the dental caries prevalence was 93.4%. The mean P-ECOHIS scores for 'child symptoms', 'child functions', 'child impact', 'parent distress', and 'the sample' were statistically significantly higher for children with MaxCASTcodes 5 and 6 (dentine and pulpally involved cavities, respectively) than for those with MaxCASTcode 3. CONCLUSION: The presence of cavitated teeth with and without pulpal involvement impacts negatively on the OHRQoL of 3-year-old children.

Reducing carious lesions during the first 4 years of life: An interprofessional approach.

BACKGROUND: Caries in Peruvian 0- through 3-year-olds is high. The dental profession should collaborate with nurses at mother and child health (MCH) clinics for reducing the disease. In this randomized clinical trial, the authors tested an integrated intervention program implemented by nurses and dentists. METHODS: The authors developed age-specific (0-3 years) oral health-related information and activity record cards and validated them for nurses to use after being educated about oral health issues and mouth inspection. The authors trained dentists in atraumatic restorative treatment. The active intervention group (AG) participated in the integrated intervention program, the passive intervention group (PG) received only the oral health-related information and activity record cards, and the control group (CG) received only a lecture. The examiners assessed caries status according to the Caries Assessment Spectrum and Treatment instrument. The authors used analysis of variance and the Tamhane method to analyze the data. RESULTS: The sample consisted of 368 children with a mean age of 3.1 years. The 3-year dropout percentage was 40.5%. The prevalence of cavitated dentin carious lesions was statistically significantly lower in the AG (10.0%, confidence interval [CI] 4.1 to 19.5) than in the PG (60.5%, CI 48.6 to 71.5) and CG (63.0%, CI 50.9 to 74.0) after 3 years (P < .001). Enamel carious lesions (62.9%) were most prevalent in the AG, whereas carious lesions were most prevalent in the PG (28.9%) and CG (32.9%). CONCLUSIONS: Incorporation of specific oral health care activities into the existing MCH program, implemented by trained nurses and supported by health center dentists, reduced the burden of caries in 3-year-olds substantially. PRACTICAL IMPLICATIONS: The oral health care professionals in Peru should collaborate with personnel of MCH clinics to curb caries in 0- through 3-year-olds.

How Long does it Take to Examine Young Children with the Caries ICDAS System and how do they Respond?

A caries-epidemiological study using the ICDASepi-merged system was conducted in Colombian young children. This study aimed at associating the time needed for the clinical examination of caries and caries risk in 1 to 5-year-old children according to age and caries risk, and to assess behavior and child pain self-perception during examination according to age. After IRB approval and given parents/caregivers' informed consent, seven trained examiners assessed 1 to 5-year olds in kindergartens under local field conditions. ICDASepi-merged caries experience (depiMEmf) was assessed as follows: Initial-depi (ICDAS 1/2 without air-drying); Moderate-dM (ICDAS 3,4); Extensive-dE (ICDAS 5,6) lesions; due-to-caries fillings-f and missing-m surfaces/teeth. Caries risk was assessed with Cariogram®. Child's behavior (Frankl-Behavior-Rating-Scale) and self-perceived pain (Visual-Analogue-Scale-of-Faces) during examination were evaluated. Clinical examination time was recorded with a stopwatch. A total of 592 children participated (1-yr.: n=31; 2-yrs.: n=96; 3-yrs.: n=155; 4-yrs.: n=209, 5-yrs.: n=101). The depiMEmfs prevalence was of 79.9% and the mean 8.4±10.4. Most were high-caries-risk children (68.9%). The majority (58.9%) showed ≥ positive-behavior and ≤ light-pain self-perception (88.4%). Mean clinical examination time was around 3.5 minutes (216.9±133.9 seconds). For 5-yr. olds it corresponded to 4 minutes (240.4±145.0 seconds) vs. 2 minutes (122.8±80.1 seconds) for 1-yr. olds (Kruskal-Wallis; p=0.00). For high- and low-caries risk children it was around 4.3 minutes (255.7±118.5 seconds) and 3.3 minutes (201.3±129.4 seconds), respectively (ANOVA; p=0.01). This study demonstrates using the ICDAS system in young children is feasible, taking less than 4 minutes for the clinical examination without children behavior/pain self-perception issues.

Resumo Um estudo epidemiológico de cárie usando o sistema ICDAS foi realizado em crianças pequenas colombianas. O objetivo deste estudo foi associar o tempo necessário para o exame clínico da cárie e o risco de cárie em crianças de 1 a 5 anos de acordo com a idade e o risco de cárie e avaliar a autopercepção do comportamento e da dor na criança durante o exame, de acordo com a idade. Após a aprovação do comitê de ética e do consentimento informado dos pais/responsáveis, sete examinadores treinados avaliaram crianças de 1 a 5 anos em creches em condições locais de campo. A experiência de cárie do ICDAS (depiMEmf) foi avaliada da seguinte forma: Epi-depi inicial (ICDAS 1/2 sem secagem ao ar); Moderado-dM (ICDAS 3,4); lesões extensas de dE (ICDAS 5,6); restaurações devido a cárie -f e superfícies/dentes ausentes-m. O risco de cárie foi avaliado com Cariogram®. O comportamento de crianças (Frankl-Behavior-Rating-Scale) e a autopercepção de dor (Escala Visual-Analógica-de-Rostos) durante o exame foram avaliados. O tempo de exame clínico foi registrado com um cronômetro. 592 crianças participaram (1 ano: n = 31; 2 anos: n = 96; 3 anos: n = 155; 4 anos: n = 209, 5 anos: n = 101 ). A prevalência do depiMEmfs foi de 79,9% e a média de 8,4 ± 10,4. A maioria era de crianças com alto risco de cárie (68,9%). A maioria (58,9%) apresentou ≥ comportamento positivo e ≤ autopercepção de dor leve (88,4%). O tempo médio de exame clínico foi em torno de 3,5 min (216,9 ± 133,9 s). Para crianças de 5 anos, correspondeu a 4 min (240,4 ± 145,0 s) vs. 2 min (122,8 ± 80,1 s) para crianças de 1 ano de idade (Kruskal-Wallis; p = 0,00). Para crianças com alto e baixo risco de cárie, foi em torno de 4,3 min (255,7 ± 118,5 s) e 3,3 min (201,3 ± 129,4 s), respectivamente (ANOVA; p = 0,01). Este estudo demonstra que a utilização do sistema ICDAS em crianças pequenas é viável, levando menos de 4 min para o exame clínico sem problemas de autopercepção de comportamento/ dor em crianças.

Tratamento Restaurador Atraumático: atualidades e perspectivas / Atraumatic Restorative Treatment: advances and perspectives

O Tratamento Restaurador Atraumático (Atraumatic Restorative Treatment) atualmente é entendido como uma abordagem minimamente invasiva que compreende medidas preventivas, terapêuticas e restauradoras em relação à cárie dental e no controle dessa doença, inclusive no atendimento à pacientes especiais. O tratamento é feito apenas com a utilização de instrumentos manuais e com o uso do cimento de ionômero de vidro (CIV), aplicado para o selamento de cicatrículas e fissuras em risco de cárie e na restauração de dentes com cavidades nas quais as fissuras adjacentes também são seladas. As razões mais frequentes para as falhas das restaurações ART estão associadas ao deslocamento do ionômero de vidro em função de insuficiente remoção de esmalte desmineralizado e dentina decomposta; manipulação inadequada do pó/líquido do ionômero de vidro; grau de umidade e temperatura da mistura do ionômero no momento da manipulação; não preenchimento completo da cavidade com o material restaurador; contaminação por saliva e/ou sangue; limpeza ou condicionamento insuficiente das cavidades; grau de cooperação do paciente; habilidade do operador. Materiais com propriedades estéticas melhoradas têm surgido no mercado odontológico e devem servir de estímulo para a realização de trabalhos de ART nos dentes anteriores. No preparo do dente para as restaurações de ART de Classe II, é recomendável confeccionar retenções adicionais nas paredes vestibular e lingual para evitar o deslocamento da restauração. O ART é capaz de diminuir o nível de ansiedade e medo dos pacientes quando o operador não é um especialista, além de ser um tratamento que proporciona menor dor e desconforto, podendo ser realizado num consultório odontológico ou fora dele. Sugestões para novas agendas de pesquisa sobre o ART são propostas.

The Atraumatic Restorative Treatment (A R T) is understood as a minimally invasive approach comprising preventive, therapeutic and restorative measures in relation to dental caries and in the control of this disease, including in attendance to patients of special needs. The treatment is done only with the use of hand instruments and with the use of glass ionomer cement (GIC), applied to the sealing of pits and fissures in caries risk and in the restoration of teeth with cavities in which the adjacent pits and fissures are also sealed. The most frequent reasons for the failures of ART restorations are the displacement of the glass ionomer due to inadequate removal of demineralized enamel and dentin decomposed; improper handling of the glass ionomer powder and liquid; degree of humidity and temperature of the mix GIC at the time of handling; not full fill of the cavity with the restorative material; contamination by saliva and/or blood; cleaning or conditioning of cavities; degree of cooperation of the patient; skill of the operator. Materials with improved aesthetic properties have emerged on the market and must serve as a stimulus for the works of ART in the anterior teeth. In the preparation of the tooth for class II ART restorations, we recommend that you make additional retentions in the vestibular and lingual walls to prevent the displacement of the restoration. The ART is able to reduce the level of anxiety and fear of patients when the operator is not an expert, and is a treatment that provides less pain and discomfort, and can be performed in a dental office or out of it. Suggestions for new research agendas on the ART are proposed.

Barriers to adopting and implementing an oral health programme for managing early childhood caries through primary health care providers in Lima, Peru.

BACKGROUND: To identify barriers to participation in a primary oral health care programme aimed at preventing early childhood caries, as perceived by nurses. METHODS: Of a total of 140 randomly selected nurses employed in 40 government health centres in Lima, 123 completed a pre-tested questionnaire. Background variables were districts' 'socio-economic status' (SES) and 'years of experience'. Factor analysis was performed. ANOVA was applied for testing the influence of the background variables on the barrier factors. Chi-square test was applied to test for differences between single item barriers and the background variables. The Likert-scale (1-4) was used. RESULTS: There was no statistical significant effect of 'SES' or of 'years of experience' of nurses on any of the 7 barrier factors, nor on the 11 single item barrier factors. The highest mean score (3.81) was obtained for the barrier factor 'importance of oral health', followed by 'perceived responsibility' (3.44). The lowest mean score was (1.70) for 'knowledge on caries prevention'. CONCLUSIONS: Nurses consider oral health very important and are willing to participate actively in programmes aimed at reducing Early Childhood Caries, provided that they will be trained well and that the director and dentists of the health centre give their consent.

Early Childhood Oral Health Impact Scale (ECOHIS). Translation and validation in Spanish language.

Health is currently recognized as lying in the individual process rooted in genes, personal habits, the social model and the understanding of the ideological standpoint from which it is viewed. The aim of this study was to validate the Early Childhood Oral Health Impact Scale (ECOHIS) for use in Latin American communities, in order to demonstrate its efficacy for determining the impact of dental condition on children under 5 years of age and their families. The ECOHIS explores two domains: impact on children (9 questions) and on families (4 questions). Validation in Spanish was done in four stages. Stage I included translation and back-translation of the questionnaire (English-Spanish-English). Stage II was a pilot test on families in Venezuela to test stability (test-retest) and make semantic adjustments. Stage III included validation of the questionnaire applied to a Venezuelan sample (n = 50) and two Argentine samples (A and B, made up of families with and without social risk, respectively; n = 95), and consisted of statistical analysis to check the questionnaire's internal consistency and discriminant capacity. In the final stage, parents were given feedback on the results and significance of each domain in the questionnaire. From the results of this study it may be concluded that the Spanish version of the ECOHIS was reliable and valid for administering to populations with homogeneous social risk, and that parents without social risk factors (AC/B) have significantly greater perception of the impact of oral health on the family's quality of life. The trends recorded suggest that (a) larger samples should be used, including variables for diagnosing social vulnerability or general risk, (b) the association with dental condition should be established by applying indicators to discriminate distinct cut-off points in the dental caries process and (c) it should be ascertained whether there are changes in perception of the impact on quality of life before and after dental treatments, including impact on general health condition.

Early childhood oral health impact scale (ECOHIS): translation and validation in Spanish language

En la actualidad, se reconoce que la salud está en el proceso individual enraizado en los genes, los hábitos personalísimos, el modelo social y la comprensión de la ideología de la cual depende en realidad el ángulo desde el cual se la examina. El objetivode este estudio fue validar el Early Childhood Oral Health Impact Scale (ECOHIS) en comunidades latinoamericanas, a fin de demostrar su eficacia para determinar el impacto que el estado dentario produce sobre los niños menores de 5 años y su familia. El ECOHIS explora dos dominios: elimpacto sobre el niño (9 preguntas) y sobre la familia (4 preguntas). Para la validación en el idioma español se desarrollaron cuatro etapas. La etapa I: incluyó la traducción reversa del cuestionario (ingleìs-español.ingles). La etapa II consistió en la prueba piloto realizada en familias venezolanas para comprobar la estabilidad (test-retest) y realizar el ajuste semántico. La etapaIII incluyó la validación del cuestionario aplicado en una muestra venezolana (n=50) y en dos muestras argentinas (AC/A y AC/B, constituidas por familias con y sin riesgo social, respectivamente;n=95). En la última etapa se realizó la devolución de la información a los padres acerca de los resultados y del significado de cada uno de los dominios del cuestionario. Los resultados obtenidos en el presente estudio permiten concluir que la versión en español del ECOHIS resulto confiable y válida para su aplicación en poblaciones con riesgo social homogéneo y que los padres sin factores de riesgo social (AC/B) muestran una percepción significativamente mayor del impacto que el estado bucodental determina sobre la calidad de vida de la familia. Las tendencias registradas permiten recomendar la conveniencia de (a) ampliar el tamaño de las muestras aplicadas en este estudio, incorporando variables que instalen el diagnóstico de factores de vulnerabilidad social o de riesgo generales (b) establecer laasociación existente con el estado dentario.

Effect of APF gel application time on enamel demineralization and fluoride uptake in situ.

This in situ crossover and blind study was conducted to investigate the effect of professional acidulated phosphate fluoride (APF) gel application time on the subsequent inhibition of enamel demineralization. During 3 phases of 28 days each, 15 volunteers wore palatal appliances containing 4 enamel blocks, which were subjected to 3 treatment groups: not treated (control) and pre-treated with APF gel for 1 or 4 min. Dental plaque was allowed to accumulate on the blocks and the appliances were immersed in 10% sucrose solution 3 times a day simulating a cariogenic challenge. After each phase, the blocks were removed to evaluate enamel demineralization and concentration of fluoride (F) remaining after the cariogenic challenge. F formed on enamel was determined in additional enamel blocks subjected only to APF gel application. APF gel was efficient in reducing enamel demineralization (p<0.05), irrespective of the application time (p>0.05). Also, the concentration of the F formed and retained on enamel was significantly higher after APF gel application (p<0.05), but the effect of time of application was not statistically significant (p>0.05). The results suggest that APF application for either 1 or 4 min is equally efficient to increase F concentration in enamel and reduce enamel demineralization.
