Association of Oral Health Assessment Tool Findings With Periodontal Screening Outcomes in Adults With Diabetes.
Article in Clinical and experimental dental research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundPeriodontal disease is common among adults with diabetes, yet periodontal screening is rarely incorporated into routine outpatient diabetes care. The Oral Health Assessment Tool (OHAT) is a structured observational tool designed for non-dental healthcare professionals; however, its relationship with periodontal screening findings remains unclear.
objectivesTo examine the association between OHAT findings and periodontal screening outcomes in adults attending diabetes outpatient clinics.
methodsThis cross-sectional study included adults with type 1 or type 2 diabetes at a tertiary hospital in Sydney, Australia. Periodontal screening was performed using the Periodontal Screening and Recording (PSR) system, and oral health was assessed using OHAT. Periodontal status was dichotomized as no/mild (PSR 0-2) versus moderate-to-severe (PSR ≥ 3). Logistic regression examined associations of OHAT domains and total OHAT burden with periodontal status. Covariate-adjusted models assessed robustness. Screening performance was evaluated using sensitivity, specificity, and predictive values.
resultsAmong 120 participants (mean age 61.5 years, 64.2% with type 2 diabetes), 71.4% demonstrated moderate-to-severe periodontal findings. Mean OHAT score was 4.99 (SD 2.02). Change/unhealthy ratings for tongue (OR 3.23, 95% CI 1.30-8.02), gums and oral tissues (OR 4.59, 95% CI 1.78-11.85), and increasing categories of decayed teeth (OR 2.06, 95% CI 1.05-4.05) were associated with moderate-to-severe findings. Higher total OHAT score (> 5 vs. ≤ 5) was strongly associated with moderate-to-severe periodontal findings (OR 7.00, 95% CI 2.25-21.76), with consistent results. This threshold showed high specificity (87.5%) and positive predictive value (90.9%), but moderate sensitivity (50.0%).
conclusionOHAT findings were associated with moderate-to-severe periodontal screening findings among adults with diabetes, supporting further evaluation of OHAT as a pragmatic screening and referral aid in settings where formal periodontal assessment is not routinely available. Its performance when administered by non-dental clinicians requires further investigation.
