Periodontal Health, Bite Force and Oral Health-Related Quality of Life of Obese Older Adults Using Removable Partial Dentures.
Article in Journal of oral rehabilitation, 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
backgroundObesity is associated with periodontal disease, which compromises chewing by reducing masticatory efficiency. However, little is known about periodontal health and the use of removable prostheses in obese older adults.
objectiveTo evaluate the effects of removable partial denture (RPD) insertion on periodontal condition, maximum bite force (MBF), and oral health-related quality of life (OHRQoL) in obese and normal-weight older adults. MATERIAL AND
methodsEdentulous older adults in the maxilla and partially edentulous in the mandible were assigned to obese (71.9 ± 5.0 years; n = 12, 6 women and 6 men) and normal-weight (69.9 ± 6.7 years; n = 6 women and 6 men) groups. Periodontal parameters (probing depth, clinical attachment loss, gingival recession, bleeding on probing) were measured with William's probe, and plaque was assessed with the modified O'Leary index. MBF was recorded with pressure sensors, and OHRQoL was evaluated with the OHIP-14. Periodontal parameters and MBF were measured before and 3, 6, 9, and 12 months after RPD insertion, while OHRQoL was measured before, and after 6 and 12 months. Data were analysed by repeated-measures ANOVA with Bonferroni post hoc tests (α = 0.05).
resultsObese individuals showed higher bleeding on probing (p = 0.02) and greater MBF (p = 0.002) at all time points. MBF increased in both groups after 3 months, while OHRQoL remained lower in obese individuals (p = 0.01). Both groups showed significant plaque reduction after RPD insertion (p < 0.05).
conclusionObese older adults wearing RPDs exhibit greater periodontal impairment and poorer OHRQoL, despite similar improvements in MBF and plaque reduction. These findings underscore the need for closer periodontal monitoring and targeted oral health strategies for obese older adults receiving RPDs.
