A sample of 603 11-year-old children from four low fluoride (less than 0.15 ppm) and one higher fluoride (1.56 ppm) communities in Namibia and KwaZulu were examined in 1988 using the CPITN. In a rural low fluoride community in Namibia only 6 per cent of children had healthy mouths compared with 42-58 per cent in the other communities. The main periodontal lesion seen was gingival bleeding (19-47 per cent) followed by calculus (6-47 per cent). There is a need for both oral hygiene improvement and simple intervention.
