title: Caries prevalence in children from Valencia (Spain) using ICDAS II criteria, 2010.
abstract: OBJECTIVE
  To assess the oral health status of the child population and its evolution over the 2004-2010 period.
  
  
  METHODS
  A descriptive cross-sectional study of the entire schoolchild population of the Valencia region of Spain was conducted using cluster sampling. Seventy schools were selected. The sample size was 1373 pupils, aged 6, 12 and 15 years. The children were examined in November and December 2010, at their schools, by 6 examiners calibrated in the ICDAS II method. The descriptive statistics, comparison of means and comparison of proportions (p<0.05) were recorded.
  
  
  RESULTS
  The caries prevalence (ICDAS 4-6>0) was 30% in primary dentition at 6 years and 37.7% and 43.6% in permanent dentition at 12 and 15 years respectively. At 6, 12 and 15 years, the df.t/DMF. TICDASII 4-6 scores were 0.98, 0.83 and 1.08, the df.s/DMF.SICDASII 4-6 scores were 1.43, 1.27 and 1.64 and the care index results were 14.3%, 59% and 71.3% respectively.
  
  
  CONCLUSIONS
  Both the caries indices (df.t at 6 years and DMF.T at 12 and 15) and caries prevalence have improved, as the values obtained were lower than in 2004. Using the comparison at 95% CI, between both years, the improvement was only noticeable in the 15 year-old group. The care index continued to be low at 6 years of age but higher values than in 2004 were found at 12 and 15 years. Social class continued to influence the child caries indicators.
