Resumen:
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 D-3 (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 < 0.001), respectively. The mean
D3MFT was 0.49 (+/-1.01) in the 0.70 ppm community and 0.61 (+/-1.47) in
the 1.50 ppm community (p = 0.349). A logistic regression model for
caries (D-3>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. Copyright (C) 2013 S. Karger AG, Basel
