Incidence and progression of caries experience in Germany: results of the 6th German Oral Health Study (DMS • 6).

Key Points

The study aims to evaluate the incidence and progression of dental caries across different age groups in Germany over nine years.
Conducted a 9-year longitudinal study
Analyzed data across three age groups: adolescents, adults, and seniors
Evaluated changes in caries experience, including filled, missing, and extracted teeth
Adolescents showed more filled teeth, while adults had increased filled and missing teeth.
Seniors presented with a higher number of extracted teeth.
Individuals with early caries experience had greater increments in caries.
Notable rise in root caries among adults and seniors was observed.

Abstract

This 9-year longitudinal study demonstrated caries increments during the life course in all three age groups. Adolescents predominantly presented with newly filled teeth, adults showed increased numbers of filled and missing teeth, and seniors primarily presented with a larger number of extracted teeth. Individuals with early caries experience exhibited greater increments. The pronounced increase in root caries among adults and seniors highlights the need to intensify targeted root-surface-focused prevention alongside ongoing primary prevention for high-risk groups.
