“…The presence of fluorosis in various regions of Ecuador has been reported, especially in central highland areas (16); it is related to the appearance of high levels of fluoride in the water supply network; however, different studies conducted in the same region report a normal fluoride concentration (17), suggesting that there are other factors that produce dental fluorosis. For this reason, one of the goals of this study is to determine the relationship of these factors with the prevalence and severity of dental fluorosis in schoolchildren, between 10-12 years of age, from ¨Pimampiro¨, Imbabura Province; ¨Colta¨, Chimborazo Province, and ¨Quito¨, Pichincha Province.…”

Background: To determine the prevalence of dental fluorosis in 10-12 year-old school children, in three provinces of the inter-andean Region of Ecuador: Imbabura, Pichincha and Chimborazo, as well as the relationship between certain factors, considering that the latest studies go back to the year 2009. Material and Methods: A cross-sectional and observational study was proposed. A sample of 599 was calculated at 95% of confidence considering population projections for children between 10 and 12 old of three zones of Ecuador. However, 608 school children, who had the acceptance and informed consent of their parents to participate, completed a survey about factors associated with dental fluorosis. Once the survey was completed, the vestibular surfaces of the upper and lower anterior teeth of the infant were photographed, following standardized distance and light procedures. Three evaluators, trained in the detection of fluorosis using the Thylstrup and Fejerskov index, analyzed the photographs. The Stata 13.0 software was used for the statistical analysis, with a level of significance of 5% and with a confidence interval of 95%. To relate the risk factor of fluorosis, a multinomial logistic model was used. Results: The prevalence of dental fluorosis was of 89.96%, with a greater presence of grade 2 TF. A positive statistical relationship and statistical significance was detected between dental fluorosis and consumption of bottled beverages. Also the amount of toothpaste used and its ingestion during brushing (p = 0.000) were analyzed. Conclusions: The populations evaluated, that are related to the consumption of bottled beverages and involuntary toothpaste ingestion, and have a high prevalence of a mild level of fluorosis.

“…This study shows that the local water in Transylvania has a lower concentration of Ca and Mg than the concentration recommended by the specialists -this is insufficient to promote tooth remineralization, though sufficient levels of F are present to protect against caries. 9 Fluoride values obtained from the water samples classify Transylvania as fluoride-lacking area. In the analyzed water samples with reduced fluoride concentrations, low concentrations of Ca and Mg were also found, showing reduced overall mineralization of water which together with In all batches, the Pearson coefficient value revealed a high correlation between the Ca and Mg values in the drinking water and the Ca concentration in the subjects' dentine.Being an essential element for healthy teeth, F is added to drinking water to prevent caries.…”

Objective: This study estimated the concentration of Ca, Mg and F in drinking water from five counties in Transylvania, Romania and correlated these with mineral values found in the dentine of permanent carious teeth. The role of these minerals on the re-mineralization of teeth is broadly analyzed. Methods: The study consists of two parts: the first part is a pilot study aimed at determining the concentration of Ca, Mg and F in the dentine of permanent carious teeth of 75 male adults with residence in five counties in Transylvania. The second part is an evaluation of the levels of mineral composition in the drinking water from these counties. Mineral concentrations in dentine and drinking water samples, were determined in the laboratories of the public health institute and the research and analysis institute in Cluj Napoca, Romania. Results: Statistically we found a direct and significant correlation between the Ca, Mg and F contain from the water samples and Ca, Mg and F contain from the dentine samples and an inverse correlation was statistically highlighted between Ca found in water samples and the F concentration in dentine samples. Improperly water mineralization associated with a general lack of fluoride reveals a potential negative impact on consumer health, including the oral-jaw system. Conclusions: The results of this study indicate the need for improving the prevention of dental caries which is a priority in promoting orthodontic health for children. The variability in dentine minerals indicates the fact that permanent molar dentin represents an important biomarker for exposure. The future research will have to take into consideration the community residency status and the fact that these studies require a large sample to separate individual and community level contributions to dentin fluoride. Considering these notifications, we conclude that minerals are highly associated with caries. doi: https://doi.org/10.12669/pjms.36.3.1820 How to cite this:Razvan C, Popa M, Incze AM, Cristina C.
