Comparison of Water Defluoridation Using Different Techniques

Table 1

Effects of drinking water fluoride contents on human health [5].

Fluoride level, mg/L	Health impact
<0.5	Dental caries
0.5–1.5	Optimum dental health
1.5–4.0	Dental fluorosis
4.0–10	Dental and skeletal fluorosis
>10.0	Crippling fluorosis
