1386, 5-6-yr-old and 1326, 12-yr-old schoolchildren in the mainly rura
l province of Matabeleland South, in Zimbabwe, were examined for denta
l caries and interviewed about their oral hygiene practices. Fluoride
contents of the drinking water source of the schools were determined a
nd were found to be in the range 0.05-2.5 ppm. Among 5-6-yr-old childr
en, 25.2% were affected with caries and the mean drift score was 0.6 w
hereas 19.8% of the 12-yr-old children had caries, and the mean DMFT s
core was 0.3. In both age groups low fluoride levels in drinking water
(<0.8 ppm) were associated with higher prevalence of caries (5-6-yr-o
lds: OR 2.47; 12-yr-olds: OR 2.09). Chewing sticks were the most commo
nly applied oral hygiene practice. Children who reported using chewing
sticks had fewer carious lesions than children who reported the use o
f toothbrush and toothpaste.
