Dental Caries among over 1.5 Million Records of Schoolchildren in Singapore, 2007-2019: Age-Period-Cohort Effect Analyses.
Introduction: This study aimed to examine the effects of age, period (historical events), and cohort (generational impact) (APC) on caries prevalence and mean DMFT among Singapore schoolchildren from 2007 to 2019.
Methods: Anonymised records of all 6-year-old primary 1 (P1), 11-year-old primary 6 (P6), and 14-year-old secondary 3 (S3) students before the start of each school year between 2007 and 2019 were extracted from the Integrated Dental Electronic Assessment System (IDEAS), categorised by school level, ethnicity, and sex. Poisson regression and partial least squares regressions were applied to estimate APC effects.
Results: In total, 502,339 P1, 535,579 P6, and 496,725 S3 records were included from 2007 to 2019, with 1,058,589 (69.0%) Chinese, 187,948 (12.2%) Malay, and 152,618 (9.9%) Indian students; 245,447 (48.8%) P1, 259,389 (48.4%) P6, and 243,941 (49.1%) S3 students were girls. Overall, the APC effects on caries prevalence and mean DMFT showed a strong age effect, with the lowest prevalence in the youngest P1 group and the highest in the oldest S3 group. Period and cohort effects were identified, with the prevalence decreasing among those born after 1995 and the lowest prevalence rate in 2013. Similarly, period and cohort effects on mean DMFT were also detected, with decreased mean DMFT after period 2009 and the highest mean DMFT (0.72 in P6 and 1.13 in S3) in cohort 1995.
Conclusion: Caries prevalence and DMFT increased with age. While both decreased in individuals born after 1995, mean DMFT began to rise again in those born after 2003.
期刊介绍：
''Caries Research'' publishes epidemiological, clinical and laboratory studies in dental caries, erosion and related dental diseases. Some studies build on the considerable advances already made in caries prevention, e.g. through fluoride application. Some aim to improve understanding of the increasingly important problem of dental erosion and the associated tooth wear process. Others monitor the changing pattern of caries in different populations, explore improved methods of diagnosis or evaluate methods of prevention or treatment. The broad coverage of current research has given the journal an international reputation as an indispensable source for both basic scientists and clinicians engaged in understanding, investigating and preventing dental disease.
