“Fluorosis…associated with a higher prevalence of dental caries”

García-Pérez A., Irigoyen-Camacho M.E., Borges-Yáñez A. Fluorosis and Dental Caries in Mexican Schoolchildren Residing in Areas with Different Water Fluoride Concentrations and Receiving Fluoridated Salt. Caries Res 2013;47:299–308 (DOI:10.1159/000346616)

Objective: To explore the association between fluoride in drinking water and the prevalence and severity of fluorosis and dental caries in children living in communities receiving fluoridated salt.

Material and Methods: Participants were schoolchildren (n = 457) living in two rural areas of the State of Morelos, Mexico, where the water fluoride concentration was 0.70 or 1.50 ppm. Dental caries status was assessed using Pitts’ criteria. Lesions that were classified as D3 (decayed) were identified to determine the decayed, missing, and filled teeth index (D3MFT). Fluorosis was assessed using the Thylstrup-Fejerskov Index (TFI). Information regarding drinking water source and oral hygiene practices (tooth brushing frequency, dentifrice use, and oral hygiene index) was obtained.

Results: The prevalence of fluorosis (TFI ≥1) in communities with 0.70 and 1.50 ppm water fluoride was 39.4 and 60.5% (p = 0.014), respectively, while the prevalence of more severe forms (TFI ≥4) was 7.9 and 25.5% (p 1) showed that higher fluorosis categories (TFI 5–6 OR = 6.81, p = 0.001) were associated with higher caries experience, adjusted by age, number of teeth present, tooth brushing frequency, bottled water use, and natural water fluoride concentration.

Conclusions: The prevalence of fluorosis was associated with the water fluoride concentration. Fluorosis at moderate and severe levels was associated with a higher prevalence of dental caries, compared with lesser degrees of fluorosis. The impact of dental fluorosis should be considered in dental public health programs.

East Orange Water Commission (NJ) officials charged with conspiracy

“Mansmann and Mowell allegedly conspired to falsify mandatory testing of the EOWC’s water supply to hide elevated levels of the contaminant tetrachlorethene, or PERC, an industrial solvent used for dry cleaning, which is classified as a probable carcinogen.”
