Abstract: | OBJECTIVES: The aim of the present study is to investigate variables of the past caries experience as indicators of future caries in a Chinese child population. METHODS: Caries was recorded at baseline and 2 years later in 433, 6-7-year-old Chinese children. Correlation coefficients between variables of the past caries experience and caries increment were calculated. Stepwise logistic regression analyses provided predictor variables. ROC curves presenting sensitivity as function of (100-specificity) were employed to summarize the obtained information. The area under the ROC curves was used as a measure of predictive accuracy. RESULTS: Twelve variables of baseline caries experience had a significant (p
