Longitudinal study of dental caries increment in Malaysian school children: A 5-year cohort study Academic Article uri icon


  • The aim of this 5-year longitudinal cohort study was to assess the prevalence, severity, and trends in caries increment and impact of the School Dental Incremental Care Programme (SDICP). Data were gathered from school dental records as part of the SDICP. A sample of 1830 children were included and checked for caries experience annually using World Health Organization criteria. In total, 95.4% of the children were caries free in 2004, and caries experience declined to 70.5% in 2009 with an average of 4.9% annually. At baseline, the mean DMFT (confidence interval [CI]) was 0.06 (0.05-0.08) and increased to 0.58 (0.53-0.63) in 2009. Children with active caries were 4.4% in 2004, and figures rose to 9.6% in 2009. The FT component increased most rapidly during these 5 years from 0.2% to 25.1%. Overall caries prevalence and increment was low in this study. Proportions of FT component were higher as compared with DT component with low rate of extractions during the latter years of the study.
