Incidence of Caries and Periodontal Disease in Abutment Versus Non-Abutment Teeth Among Removable Partial Dental Prosthesis Wearers: A Systematic Review Utilizing Synthesis without Meta-Analysis
Bibliographic record
Abstract
PURPOSE: This review compared the incidence of caries and periodontal parameters of disease activity in abutment versus non-abutment teeth in removable partial dental prosthesis (RPDP) wearers. MATERIALS AND METHODS: Two reviewers independently searched five electronic databases (PubMed, EBSCO-CINAHL Complete, EBSCO-Dentistry and Oral Sciences, Wiley Cochrane Library, and Scopus) to retrieve studies published until September 9, 2023, and selected randomized controlled trials (RCTs) and longitudinal studies (LSs) reporting at least three months of recall post-delivery. Frequency of new and recurrent caries, probing depths (PPD) in millimeters, and sites with bleeding on probing (BoP) were recorded. RESULTS: Among the 11,260 records identified, 21 reports from 20 studies (two RCTs and 18 LSs) were included. Four reports described PPD with BoP, 16 reported caries incidence, and one reported both. Synthesis without meta-analysis guidelines were followed for data analysis. Relatively stable periodontal health with 3-month to 10-year follow-up was observed. Caries incidence ranged from 11.9%-46.96% over 2-5 years. Six of the eight reports showed higher caries incidence in abutments than in controls. Cochrane risk of bias (RoB-2.0) assessment indicated high risk in one RCT and moderate risk in another. Four LSs were rated 'good' per the Newcastle-Ottawa Scale with Agency for Healthcare Research and Quality standards. Certainty of evidence was evaluated with Grading of Recommendations Assessment, Development, and Evaluation. CONCLUSIONS: Increased BoP at recalls of 3 months to 7 years was observed. Weak evidence supported stable PPD in RPDP patients. Increased caries risk in abutments compared to non-abutments suggested a need for regular follow-ups.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
