Abstract
OBJECTIVES The objectives were to measure fluoride release and assess the antimicrobial behavior of fluoride-doped nano bioactive glass (F-nBG) and nano zinc oxide (ZnO)-enriched novel dentifrices. MATERIALS AND METHODS Experimental dentifrices were synthesized by incorporating ZnO nanoparticles and F-nBG (1.5 wt% and 4 wt%) as active ingredients. The fluoride release behavior of suspensions and elutes of samples were analyzed by ion selective electrode. Antimicrobial activity and minimum bactericidal concentration against Streptococcus mutans and Lactobacillus casei were evaluated. Microbial stability against contamination was also assessed by a challenge test. RESULTS The fluoride release behavior of experimental dentifrices was higher than that of commercial dentifrices and was dependent on filler loading. The fluoride release was more from suspensions than elutes. Zones of inhibition (ZOIs) and minimum bactericidal concentration values for novel dentifrices showed direct proportionality with filler loading, and effectiveness was exhibited against both strains. Experimental dentifrices exhibited effective antibacterial potential, which could possibly be due to release of sufficient fluoride and zinc ions in aqueous media from F-nBG and ZnO present in their formulations. CONCLUSION Combination of F-nBG and ZnO may provide a multi-benefit approach for simultaneously treating early white spot lesions, reducing bacterial growth, and providing core plaque control.

ENVIRONMENTAL GEOCHEMISTRY AND HEALTH 2019; 41:1405-1417.

Abstract
Brick tea contains high concentration of fluoride. The aim of the present work was to explore whether and how the brick tea is a risk factor for dental caries and dental fluorosis among Tibetan children in Ganzi. A cross-sectional study was conducted with 368 12-year-old Tibetan children in Ganzi. Dental caries was measured by DMFT index, and dental fluorosis severity was measured by Dean's Index. Community Fluorosis Index was used to estimate public health significance of dental fluorosis. Oral health-related behaviors and awareness, dietary habits and socioeconomic status were determined by a questionnaire. Bivariate and multivariate analyses were used to determine risk factors associated with dental caries and dental fluorosis. Dental caries prevalence was 37.50%, mean DMFT was 0.84 ± 1.53, while dental fluorosis prevalence was 62.23%. Community Fluorosis Index was 1.35, indicating a medium prevalent strength of dental fluorosis. Dental fluorosis was associated with mother's regular consumption of brick tea and residence altitude, and dental caries was associated with mother's regular consumption of brick tea. Mother's regular consumption of brick tea was a risk factor for both dental fluorosis and dental caries among children. Reducing mother's brick tea consumption during pregnancy and lactation may improve oral health status of their children.

Eur Arch Paediatr Dent 2019; 20:603-607.

Abstract
PURPOSE This study investigated whether the report of mothers about the amount of dentifrice applied on a toothbrush could be a reliable method to estimate the inadvertent use of dentifrices. METHODS A cross-sectional study was conducted in a randomly selected sample of 334 mothers of children enrolled in public day care centres of a city in the Brazilian northeast. Initially, the mothers chose the figure corresponding to the amount of dentifrice used during their children's daily toothbrushing. Then, they simulated real-life conditions with the toothbrush routinely used to brush the children's teeth. The amount of dentifrice on toothbrush was weighted using an analytical scale. Data were analysed by the Kruskal-Wallis followed by the Dunn test (α = 0.05). RESULTS The weight of dentifrice on the toothbrush was high (> 0.3 g), mainly considering the categories 'covered only' and 'completely covered' that showed no statistical difference (p > 0.05). The proportion of agreement between the mothers' reports and the weight of dentifrice on the toothbrush was 0.23 (CI 0.18-0.28). CONCLUSION The mothers' report regarding the amount of dentifrice on the toothbrush by demonstrative figures was not a reliable method to estimate the inadvertent ingestion of fluoride from dentifrices.

Abstract
Resumo Há uma preocupação com o aumento da prevalência de fluorose dentária, que depende da dose de fluoreto (F) a que as crianças são submetidas durante a formação dos dentes. A temperatura ambiental afeta a ingestão de água e, portanto, seria importante avaliar se as crianças que vivem em uma região de clima semiárido estão expostas a uma dose excessiva de F. Assim, o objetivo do presente estudo foi determinar a dose total de F a que as crianças são expostas durante a idade crítica para a fluorose dentária, tendo dieta (água e alimentos) e dentifrício como fontes de F, em uma região de clima semiárido no Brasil. Metodologia: foram selecionadas 26 crianças com idade de 25,2 ± 9,1 meses, residentes em Feira de Santana-BA. Foram coletadas amostras de dieta-duplicada, água, produtos de escovação e dentifrícios. A concentração de F foi determinada após o devido preparo das amostras, utilizando um eletrodo específico. Resultados: a média e o desvio padrão de dose (mg F / kg / dia) em função da dieta, dentifrício e total foram, respectivamente: 0,016 ± 0,010; 0,030 ± 0,039 e 0,047 ± 0,043. Conclusões: as crianças avaliadas, residentes em uma região de clima semiárido, não estão expostas a uma dose de risco de fluorose dentária.
