摘要

Objectives To systematically review the association between education and tooth loss.

Methods We performed an electronic search of PubMed following PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) guidelines with a focused PICO (population/problem, intervention, comparison, outcome) question: are adults with low educational attainment more prone to tooth loss than adults with higher education? Observational studies published between 2000–2022 examining adults ≥18 years with clinical or self-reported tooth loss were included. Quality of the reports was established using the Newcastle-Ottawa Scale.

Results We identified 30 studies (735,576 individuals) across 15 countries. The majority were cross-sectional (90%) and rated as low/moderate quality (67%). Educational level was assessed as years of schooling or categorical attainment. Tooth loss was measured through clinical examination (53.3%) or self-report (46.7%). Primary education or less was consistently linked to higher likelihood of edentulism (odds ratio [OR] range: 2–4.9), fewer remaining teeth (OR range: 1.2–5.8), and greater tooth loss (OR range: 1.2–2.1) relative to higher levels. A university degree significantly reduced the odds of edentulism or tooth loss (OR range 0.3–0.75) compared to lower levels.

Conclusions Lower educational attainment is associated with increased tooth loss. These findings provide a foundation for developing evidence-based policies and targeted interventions to address tooth loss in vulnerable populations.
