Influence of oral health on smoking cessation intention in current smokers with insights from a nationally representative survey.

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
This study examined the influence of oral health factors, including oral health status, behaviors, and service utilization, on smoking cessation intentions among current smokers. We conducted a cross-sectional analysis using data from the Korean Community Health Survey (2010-2023), which included 551,982 current smokers. The primary outcome was smoking cessation intention, and key predictors included self-rated oral health, chewing difficulty, periodontal symptoms, oral health behaviors (brushing after lunch, flossing), and service utilization (dental checkups, dental scaling, unmet dental care needs). Multiple logistic regression models were employed, adjusting for sociodemographic and smoking-related factors. Among smokers, 66.3% intended to quit. Our findings suggest that several oral health-related factors are modestly but significantly associated with smoking cessation intention among current smokers. Specifically, individuals with better self-rated oral health were slightly more likely to report an intention to quit smoking (OR 1.09; 95% CI 1.01-1.19). Similarly, chewing difficulty was positively associated with cessation intention (OR 1.14; 95% CI 1.05-1.25), possibly reflecting heightened perceived health risks. Positive oral hygiene behaviors, such as brushing after lunch (OR 1.14; 95% CI 1.07-1.22) and flossing (OR 1.22; 95% CI 1.11-1.34), were also associated with increased quit intention, suggesting a broader health-conscious attitude. Additionally, unmet dental care needs were associated with greater likelihood of quit intention (OR 1.17; 95% CI 1.08-1.27), potentially indicating increased awareness of healthcare access and oral disease burden. These findings suggest that both adverse oral health experiences and positive oral health behaviors are associated with increased smoking cessation intention among current smokers, highlighting the relevance of oral health as a multidimensional factor in motivating quit attempts.
