Influence of School Type and Class Level on Mean Caries Experience in 12-Year-Olds in Serial Cross-Sectional National Oral Health Survey in Germany-Proposal to Adjust for Selection Bias.

Unlabelled: The objective of this study is to analyse the effects of attended school type and class level on the reported caries experience (DMFT) obtained in the serial cross-sectional National Oral Health Study in Children in Germany (NOHSC) for the WHO reference group of 12-year-olds.

Methods: Caries data from the 2016 NOHSC were adjusted for each federal state on the basis of two additional large-scale datasets for school type and class level.

Results: Twelve-year-olds in all grades in Saxony-Anhalt (n = 96,842) exhibited significantly higher DMFT values than 12-year-olds in 6th grade (n = 76,456; +0.

[Oral health trends in children : Results from the epidemiological surveys accompanying group prophylaxis in Germany].

To describe the current epidemiological trends in the dental caries experiences of children in Germany, oral health data was primarily presented on the basis of the Epidemiological Studies Accompanying Group Prophylaxis (DAJ study) for the 2015/16 schoolyear. Caries data of 301,684 children from three different age groups were available. The trends in caries development were based on previous national and regional studies conducted in Germany.
