Fluoridation of water for human consumption is a method of caries prevention that brings great social benefit, if kept at optimal levels. The increase in the production of bottled water emphasizes the need to verify whether fluoride presence in these waters occurs in sufficient quantity to prevent decay, or if it represents a significant risk of fluorosis. Objective: to compare the concentrations of fluoride present in bottled water to those declared on the labels, and to make a critical analysis of legal norms on the subject. Materials and method: this was a cross-sectional study, through which 22 samples of bottled water sold in state of Ceará, Brazil, were analyzed. Analyses were performed in duplicate by the electrometric method, and results were compared to those printed on the labels. Detailed searches by laws, resolutions, ordinances, and other official documents in force, related to the topic were performed. Results: the fluoride concentrations found ranged from 0.01 to 0.36 mgF/l. Although 72.7% of the samples were classified as fluoridated, the fluoride concentrations observed were shown to be insufficient for caries prevention. As for the rules, situations where they are not clear or even divergent were found. Conclusion: the current legislation on the subject requires updates to become more objective and to create new criteria on the use of the term “fluoridated water”.

The objective of this work was to analyze the profiles of the concentrations of resistant starch and respective properties of paste of two cassava varieties with different development stages. For the evaluation of the profile of the concentration of resistant starch and paste properties, the starches of the cassava varieties were used IAC 576/70 and Fécula Branca, which were collected with different times of cultivation (10, 11, 12, 13, 14 and 15 months), and the use of these times were according the crop of cassava variety IAC 576/70. For the analysis of paste property the apparel was used RVA and for analysis of resistant starch the enzymatic method was used. The results showed for the paste properties happened significant differences among the two varieties of cassava starch, and in some months they there wasn't differences, and as the results of resistant starch happened differences among the starches the months of July and August, and as for the different development stages only the starch of Fécula Branca that happened significant differences.
