“…635 11 ) que admitem variação na concentração ótima de 0,1ppm para os limites inferior e superior. Ao adotar este critério, considera-se adequada a concentração entre 0,7ppm e 0,9ppm, inadequada baixa quando < 0,7ppm e inadequada alta quando > 0,9ppm; c) critério III: a partir da proposta de Narvai modificada por Ramires em 2004 18 , que admite variação na concentração ótima de flúor de 0,15ppm para o limite inferior e 0,14ppm para o superior, a fim de conferir maior precisão matemática ao resultado. Para este critério considera-se adequada a concentração entre 0,65ppm e 0,94ppm; inadequada baixa quando < 0,65ppm e inadequada alta quando > 0,94ppm.…”

The fluoridation of public water supplies is considered the most efficient public health measure for dental caries prevention. However, fluoride levels in the public water supply must be kept constant and adequate for the population to gain preventive benefit. The aim of this study was to analyze fluoride levels in the public water supply of 29 Brazilian municipalities during a 48-month period from November 2004 to October 2008. Three collection sites were defined for each source of municipal public water supply. Water samples were collected monthly and analyzed at the Research Laboratory of the Nucleus for Public Health (NEPESCO), Public Health Postgraduate Program, Araçatuba Dental School (UNESP). Of the 6862 samples analyzed, the fluoride levels of 53.5% (n = 3671) were within the recommended parameters, those of 30.4% (n = 2084) were below these parameters, and those of 16.1% (n = 1107) were above recommended values. Samples from the same collection site showed temporal variability in fluoride levels. Variation was also observed among samples from collection sites with different sources within the same municipality. Although 53.5% of the samples contained the recommended fluoride levels, these findings reinforce the importance of monitoring to minimize the risk of dental fluorosis and to achieve the maximum benefit in the prevention of dental caries

Objectives: To analyse dental caries‐related quality of life (QoL) in adolescent (15–19‐year‐old) subjects in a suburban area (SA) and a downtown area (DA) of Bauru, São Paulo, Brazil, in 2009. Methods: This was a cross‐sectional, randomised study. The sample consisted of 185 and 147 adolescents from the SA and DA, respectively. The caries index used was that for decayed, missing and filled teeth (DMFT) (World Health Organization criteria). The 14‐item Oral Health Impact Profile (OHIP‐14) was used to assess QoL. The non‐parametric Mann–Whitney test, Spearman’s correlation coefficient and chi‐squared test were used in the statistical analysis. Results: The DMFT index, Significant Caries (SiC) Index and percentage of caries‐free students were similar (P > 0.05) between these populations, but findings on the Care Index differed (P < 0.05). There was a correlation between the DMFT index and OHIP‐14 score in SA subjects (mean DMFT index = 3.01) in the dimensions of physical pain (r = 0.25; P < 0.01) and psychological disability (r = 0.17; P = 0.02). The DMFT index in DA subjects (mean DMFT index = 2.95) showed a correlation with functional limitation (r = 0.19; P = 0.02). The correlation in SA subjects between the caries component (mean = 1.22) of the DMFT index and OHIP‐14 was significant only for the physical pain dimension (r = 0.16; P = 0.03). In DA subjects, correlations between the caries component (mean = 0.37) and all dimensions of OHIP‐14 were statistically significant (P < 0.05). Conclusions: Despite the similarities in means in the DMFT index, the SiC Index and the caries‐free percentage of subjects in both localities, access to dental treatment proved to be less effective for SA adolescents. Physical pain and psychological disability were the most frequent negative manifestations of impact on QoL. The SA adolescents were more negatively affected by dental caries in terms of QoL.
