To investigate the correlation of caries experience between primary teeth and the first permanent molars. A total of 100 school children 6 years old were surveyed. The caries diagnosis criteria defined by WHO were employed. The data were statistically analyzed by use of SAS. Fisher's exact test showed that there was association between the caries experience of primary teeth and that of the first permanent molars in 6-year-old children. The average dmft of primary teeth was in positive correlation with DMFT of the first permanent molars(r = 0.5629). The results were statistically significant. The primary tooth caries experience may play an important role in predicting permanent tooth caries. More attention was suggested to pay to the children with more primary teeth decayed.
