“…The investigated villages had drinking water with a low F content ( Table 1). The people in low fluorosis villages in the coastal districts drink a lot of tea and eat a lot of seafish (12,13), whereas those in moderate fluorosis villages in the Singida district con sume fluoride-containing magadi salt (Table 1). Children in these communi ties are not likely to ingest much fluoride in the first year of life.…”

“…Three reports based on findings from that survey have been published. One contained a com parison of two fluorosis indices ( 11) and the other two presented findings on the prevalence and severity o f dental fluo rosis in relation to fluoride exposure (12,13). This report contains findings on the intraoral distribution of signs of fluorosis in areas with different degrees of fluorosis and in addition it gives a 252 v a n P a len stein H e l d e r m a n et a l .…”

The similarity of the curves suggests that the later in life enamel is completed, the higher is the severity o f dental fluorosis. This relation seems to be explained by the prevailing feeding and dietary habits, which result in minimal intake of fluoride in the first 18 months of life during breastfeeding, followed by increasing fluoride ingestion in the following years through consumption of tea, seafish and F-containing magadi salt.

“…For example, additional exposure to F − occurs from consuming vegetables grown in locations with high levels of naturally-occurring F − (Poureslami et al, 2008). Tea and salt with high levels of F − can also contribute to F − intake (Mabelya et al, 1992;Cao et al, 2003). The mineral content of food, e.g., the levels of calcium and magnesium, can influence F − bioavailability due to formation of insoluble complexes (Teotia and Teotia, 1975;Cerklawski and Ridlington, 1987;Malde et al, 2004).…”

Altitude as a Risk Indicator of Dental Fluorosis in Children Residing in Areas with 0.5 and 2.5 mg Fluoride per Litre in Drinking Water

The purpose of this study was to assess the association between altitude and dental fluorisis among Ugandan children in two fluoride (F) districts while controlling for other factors related to fluorosis. A random sample of 481 children aged 10–14 years was examined for fluorosis using the Thylstrup and Fejerskov (TF) index. The prevalence and severity of dental fluorosis increased significantly with increase in altitude (900 vs. 2,200 m in the low– and 1,750 vs. 2,800 m in the high–F district) and in F concentration in the drinking water. In bivariate correlation analyses, F exposure from liquid (FEL), altitude, infant formula, vegetarianism and storing of drinking water in earthenware pots were significantly associated with the tooth prevalence of fluorosis (TPF), i.e. at a severity of TF score ≥1 (p<0.05); age and gender were not. The stepwise multiple linear regression explained 35 and 55% of the variance in TPF within the low– and high–F districts, respectively. The change in R² due to FEL was 28 and 51% points compared with 5 and 4% points due to altitude. The significant effect of FEL and altitude was confirmed by multiple logistic regression analyses. Thus, although most of the variation in the prevalence and severity of dental fluorosis was explained by the F intake from liquid, altitude was a significant risk indicator after controlling for potential confounders.
