“…The observations seen in this study are well supported by the available although limited literature. A study in Chile [Yévenes et al, 2010] collected spot urine samples (1 per child) from 2 groups of children aged 3-5 years and reported mean concentrations of F and Cr of 0.51 mg/L and 0.44 g/L, respectively, for those living in a fluoridated water (0.48 mg F/L) community ( n = 100) and 0.15 mg/L and 0.45 g/L, respectively, for the group living in a non-fluoridated water (0.1 mg F/L) community ( n = 100). In the Chilean study, the U F/Cr was not reported, but by using the reported mean urinary concentrations of F and Cr, the U F/Cr would be calculated as 1.16 mg/g (0.51 mg F/0.44 g Cr) for the fluoridated water community and 0.33 mg/g (0.15 mg F/0.45 g Cr) for the non-fluoridated water community, values which are in agreement with the findings of the present study.…”

The urinary fluoride/creatinine ratio (U_F/Cr) in a spot urine sample could be a useful systemic F exposure monitoring tool. No reference value for U_F/Cr currently exists, therefore this study aimed to establish an upper reference value for a U_F/Cr, corresponding to excessive systemic F exposure, i.e., >0.07 mg F/kg body weight (b.w.)/day, in children. Subsidiary aims were to examine the relationship between (i) total daily F intake (TDFI) and 24-h urinary F excretion (DUFE); (ii) DUFE and U_F/Cr, and (iii) TDFI and U_F/Cr. Simultaneously collected TDFI, DUFE, and urinary creatinine (U_Cr) data in children <7 years were taken from UK studies conducted from 2002 to 2014 in order to calculate U_F/Cr (mg/g) for each child. For the 158 children (mean age 5.8 years) included in the data analysis, mean TDFI and DUFE were 0.049 (SD 0.033) and 0.016 (SD 0.008) mg/kg b.w./day, respectively, and the mean U_F/Cr was 1.21 (SD 0.61) mg/g. Significant (p < 0.001) positive linear correlations were found between TDFI and DUFE, DUFE and U_F/Cr, and TDFI and U_F/Cr. The estimated upper reference value for U_F/Cr was 1.69 mg/g; this was significantly (p = 0.019) higher than the U_F/Cr (1.29) associated with optimal F exposure (0.05-0.07 mg/kg b.w./day). In conclusion, the strong positive correlation between TDFI and U_F/Cr confirms the strong association of these 2 F exposure variables and the value of a spot urine sample for prediction of TDFI (i.e., the most important risk factor in determining fluorosis occurrence and severity) in young children. Establishing an estimation of an upper reference value of 1.69 mg/g for U_F/Cr in spot urine samples could simplify and facilitate their use as a valuable tool in large epidemiological studies.

Quando o flúor foi introduzido na composição dos dentifrícios, ele se tornou um método importante na prevenção da cárie dentária. A fluorose é um problema que ocorre na época de formação dos dentes com a ingestão excessiva de flúor. Por conta disso, alguns dentistas têm recomendado dentifrícios fluoretados em baixas concentrações, ou até mesmo sem flúor em locais onde há água fluoretada no abastecimento público. Porém com base em estudos atuais, dentifrícios com baixas concentrações de flúor não tem efetividade ao combate a cárie dentária. A recomendação atual diz que os dentifrícios para crianças devem ter de 1000 a 1100 ppm de flúor, e a quantidade deve ser controlada dependendo da idade da criança. A literatura exalta ainda, que a escovação em crianças deve ser supervisionada por pais ou responsáveis para que não haja riscos da ingestão de flúor, e verificar se a criança está fazendo a escovação corretamente. Sabe se que os pais reconhecem os benefícios do flúor, porém o conhecimento sobre a relação de fluorose e flúor é pouco difundido. O presente estudo, tem como objetivo verificar o conhecimento dos responsáveis sobre a relação de fluorose e utilização de dentifrício fluoretado.
