Evaluating dental health in patients with different severity of Parkinson's disease: a cross-sectional study.
Article in BMC oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
BACKGROUND/
objectivesParkinson's disease (PD) patients appear to have an increased risk of developing dental disease. This study aimed to evaluate the status of the dental caries, oral hygiene and periodontal health among a group of Chinese PD patients with different disease severity.
methodsA total of 424 PD patients were enrolled in the study. The Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS) and Modified Hoehn and Yahr scale (HY) were used to assess PD symptoms and severity. The Decayed, Missing, and Filled Teeth index (DMFT), Community Periodontal Index for Treatment Needs (CPITN) and Simplified Oral Hygiene Index (OHI-S) were used to assess dental status. Multiple linear, binary logistic and ordinal logistic regression estimated the association between PD parameters and dental parameters.
resultsMore advanced PD stage was associated with worse periodontal health (β = 0.771, p < 0.001). More advanced PD motor impairment was associated with increased number of untreated caries (β = 0.066, p < 0.001), poorer oral hygiene (β = 0.030, p < 0.001) and periodontal status (β = 0.040, p < 0.001). Increased difficulties in chewing and swallowing were experienced in PD patients with more decayed teeth (rho = 0.218, p < 0.00019).
conclusionsAfter considering the influence of age, gender, civil status, years of education and place of residence, the findings from the present study suggested that poorer oral health was observed in more advanced staged PD patients. The findings underscore the importance of integrating oral care into the overall management of PD. CLINICAL TRIAL NUMBER: Not applicable.
