TITLE: Ten-Year Survival of Posterior Teeth in Patients with Periodontitis Following Systematic Periodontal Treatment: A Systematic Review and Meta-analysis Using Only Open-Access Evidence and Analytic Tools Background OBJECTIVES: To determine whether conclusions drawn from open-access literature using freely available analytic tools on the long-term survival of posterior teeth following periodontal therapy are consistent with previously published comprehensive reviews.
METHODS-ELIGIBILITY CRITERIA: Human studies on patients with periodontitis who received systematic periodontal therapy (non-surgical and/or surgical) with supportive care, reporting 10-year posterior tooth survival in observational cohorts or RCTs, published between January 2015 and August 2025.Open-access full text only and no language restrictions.
INFORMATION SOURCES: PubMed (MEDLINE), Europe PMC, and Google Scholar Risk of bias: The Hoy Risk of Bias Tool for prevalence studies was used to assess the risk of bias SYNTHESIS OF RESULTS: Two independent reviewers extracted data on study characteristics, interventions, outcomes, and risk of bias.
RESULTS INCLUDED STUDIES: The 11 included studies were mostly retrospective and predominantly from Germany, spanning diverse clinical settings and sample sizes, involving 90,089 teeth from patients with a median age of 54.9.
SYNTHESIS OF RESULTS: The pooled 10-year survival percentage was 89.0% (95% CI: 85% to 93%) with very high heterogeneity (I² ≈ 98%). Premolars showed a higher survival (95.0%) than molars (85.0%), confirmed by meta-regression.
DISCUSSION: Despite low GRADE certainty, open-access evidence produced estimates consistent with prior published systematic reviews, indicating that posterior teeth-particularly premolars-commonly survive long-term under maintenance.
LIMITATIONS OF EVIDENCE: High heterogeneity and retrospective designs limit generalisability, highlighting the need for prospective, multicentre studies with standardised outcome reporting.
INTERPRETATION: Open-access data and free analytic tools can yield conclusions equivalent to those from subscription-based sources, supporting their use in valid secondary research.
FUNDING: No funding was obtained for this study REGISTRATION: PROSPERO CRD420251124114.
