Introduction: If the fluoride concentration
in drinking water is lower than the standard
level, it causes dental caries and if it be
more than standard level it causes dental
fluorosis. The aim of this study was to
determine whether a relationship exists
between the groundwater fluoride(F)
concentration and dental caries in children
living in 7 areas of Nourabade Mamasani
town in Iran.
Materials & Methods: F level of the town
drinking water was measured by the
SPADNS method. All the children of the 4
age groups of 6, 9, 10, and 12 were sampled
for a total of 3349 in seven districts of the
town. All the 28 teeth of the children were
subject to this test. The drinking water in
the region is totally of groundwater supply.
The residents have essentially the same
socio-economic living standards and
nutritional conditions.
Findings: In these 7 areas, the F level in
the drinking water was from 0.53 to 1
mg/L., While the number of decayed
permanent(Dt) teeth per child ranged from
0.13and 0.34 to the number of decayed
deciduous(dt) teeth ranged from 0.5 to 3.9
Although the F level in the drinking water
was below the national level, the dental
caries were below the national level. Over
this narrow concentration range, there
appeared to be a weak association between
the F level in the drinking water and Dt and
dt. Linear regression analyses showed very
weak decreases of the Dt and dt scores with
increasing water F level is not significant.
Discussion & Conclusion: This study
shows that in low concentrations of F
ranging 0.1 to 0.53mg/L, there is a
negligible effect on prevention of dental
caries.
