Total fluoride (F) concentrations in dental plaque obtained from children aged 4-5yr and 14-15yr in F area (0.3-1.8ppm F in natural drinking water) and non F area (under 0.1ppm F) were determined by the AlF molecular absorption spectrometry. The logarithmic normal distribution was showed in F concentration of dental plapue. The geometric means of F concentration in plaque obtained from the non F area were 25.7ppm (4-5yr) and 18.1ppm (14-15yr) as dry weight. The contents of plaque in F area, contrary, were significantly higher than those in non F area (4-5yr: 54.4ppm, 14-15yr: 24.3ppm).<BR>The plapue F from 4-5yr group was significantly higher than that from 14-15yr group in both areas. A possible explanation for the different levels of F in dental plaque from two age groups might be due to the difference of plaque quality such as plapue age.<BR>The present experiments confirmed the higher levels of F in dental plaque were acquired from naturaly fluoridated drinking water.
