“…A possible explanation for these obser vations may be, as originally suggested by Galagan and Lamson [1953], that there is a positive association between mean annual maximum temperatures and total fluoride intake. In Uganda, Moller et al [1970] at tributed the unexpectedly high prevalence and severity of fluorosis to such climatic factors.…”

317 children born and raised in two rural areas of Machakos District in Kenya were examined for enamel changes. All sources of drinking water were monitored for F^–– over a period of 1 year. The children were grouped according to mean annual F^–– concentrations in the drinking water: in area Al (0.10–0.46 mg/l) 78.0% of the children exhibited enamel changes as compared to 91.2% in area A2 (0.53–0.66 mg/l) and 93.8% in area B (0.54–0.93 mg/l). The prevalence and severity of enamel changes of each tooth type increased from the lowest to the highest F^–– area. The bilateral symmetry of enamel changes was marked, indicating a systemic origin, and the intraoral distribution of severity scores corresponded to the pattern of fluoride-induced enamel changes reported by other investigators. The prevalence and severity of enamel changes, taking into account the low levels of F^–– in drinking water, was surprisingly high.

“…According to WHO, 1971, permissible limit for fluoride in drinking water is 1.0 mg/l [5], whereas USPHS, 1962 [6] has set a range of allowable concentrations for fluoride in drinking water for a region depending on its climatic conditions because the amount of water consumed and consequently the amount of fluoride ingested being influenced primarily by the air temperature [7][8][9]. The maximum allowable fluoride concentrations as established by USPHS are shown in Table 1.…”
