Abstract
En 中文
Objectives: This longitudinal study used data from the 6th German Oral Health Study (DMS center dot 6) to determine the incidence of tooth loss and prosthetic treatment over a 9-year period in participants from the DMS center dot 6 cohort who were examined in 2014 (baseline) and reexamined in 2023 (follow-up). Method and materials: The sample comprised 342 adults (43- to 52-year-olds at follow-up) and 373 seniors (73- to 82-year-olds at follow-up) who met the inclusion criteria for the DMS center dot 6 analysis set and for whom complete information on prosthetic treatments was available were included. The prevalence, extent, and incidence of tooth loss and prosthetic treatment were compared between baseline and follow-up. Results: Over the 9-year observation period, the cumulative incidence of tooth loss among seniors was twice that among adults. The level of education influenced tooth loss: seniors with > 10 years of schooling remained unchanged, whereas those with <= 10 years exhibited an increase. The cumulative incidence of edentulism was 3.2% among seniors, and no adult was edentulous at any timepoint. Among adults, the prevalence of full dentition decreased from 44.0% at baseline to 37.6% at follow-up. The proportion of fixed-denture treatments increased by 11.1 percentage points in adults and decreased by 2.8 percentage points in seniors. However, the prevalence of implants increased in both cohorts. The incidence rates (per 100 person-years) of tooth loss indicate an accelerated loss rate in seniors (seniors: 10.0 vs adults: 4.1). The incidence of new implants was similar among adults and seniors (incidence rates: 1.1 and 1.4 per 100 person-years, respectively). Conclusion: The cumulative incidence of edentulism among seniors was low, and the increase in the frequency of implant treatment appeared to effectively compensate for tooth loss, with comparable rates in both age cohorts. School education had a pronounced impact on oral health and the need for prosthetic treatment.
