The aim of this study was to assess the prevalence, extent, severity, intraoral distribution and risk indicators for erosive tooth wear (ETW) among 12-year-old schoolchildren from Montevideo, Uruguay. A population-based, cross-sectional survey was conducted using a representative sample of 1,136 12-year-old schoolchildren attending public and private schools. Parents answered questions on socioeconomic status and general health. Schoolchildren answered questions on dietary and oral hygiene habits. Two calibrated examiners recorded ETW on permanent teeth according to the Basic Erosive Wear Examination (BEWE) score system. Logistic regression models were performed to assess the association between the predictor variables and the prevalence of ETW (overall and severe ETW). Odds ratios (OR) and the respective 95% confidence intervals (CI) were estimated. The prevalence of ETW was 52.9%, being mild erosion (BEWE = 1) in the vast majority of cases (48.5%). Severe erosion (BEWE ≥2) was detected in 4.4% of schoolchildren. The overall prevalence of ETW differed significantly between categories of gender and socioeconomic status, but only between gender in the severe ETW analysis. The overall extent of ETW was significantly different between categories of gender, socioeconomic status, and swish before swallow. The extent of severe ETW differed between categories of swish before swallow and brushing frequency. In the logistic regression analysis, no association was found between the studied variables and the overall prevalence of ETW. Males were more likely to have severe ETW than females (OR = 3.22, 95% CI = 1.50-6.89). ETW may be considered a public health problem among 12-year-old-Uruguayan schoolchildren.

Fluoridated water appears to provide a better protective effect against dental caries than fluoridated household salt among schoolchildren from developing countries.

This article aims to review periodontal disease in Uruguay. International databases (PUBMED, SCOPUS, EBSCO, SciELO) were consulted. The search also included national sources (National Library of Dentistry, Documentation Center of the School of Dentistry, Ministry of Public Health, National Directorate of Health of the Armed Forces) which were searched manually. The studies found provided useful epidemiological information and allowed us to conduct a historical review of epidemiology concepts, etiopathogenesis and hegemonic currents in periodontics. Gingival disease is the most prevalent disease, while destructive periodontal conditions mainly affect adults. Age, geographical origin, social class and smoking are indicators strongly associated with these disorders. From the close reading of the articles collected we can make suggestions to be considered in future epidemiological surveys

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.

Método: Fueron analizados catorce paquetes de sal para determinar la concentración de iones fluoruro libres. Las muestras se pesaron, se diluyeron en agua desionizada, se mezclaron con TISAB II y se utilizó un electrodo específico conectado a un analizador de iones para determinar la concentración de fluoruro Resultado: La mayoría de los paquetes presentaron valores inferiores a 250 mgF / kg. Las muestras de sal gruesa mostraron concentraciones mayores a las de sal fina (p <0.05). Aquellas conteniendo fluoruro de sodio presentaron mayor concentración de fluoruro que aquellas conteniendo fluoruro de potasio (p <0.05). Dos marcas presentaron concentraciones de fluoruro cercanas a las informadas en el envase. Conclusiones: Las sales de mesa comercializadas en Montevideo, Uruguay presentaron gran variabilidad en las concentraciones de fluoruros.
