Oral health behaviors and associated factors in older adults: a cross-sectional study.
Article in Frontiers in oral health, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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: Oral health behaviors play an essential role in maintaining oral health and preventing oral diseases, which are often neglected in older adults. This study aimed to investigate the prevalence of oral health behaviors and their associated factors in older adults. Methods: This cross-sectional study included participants aged 65 years or older who attended a university dental hospital in Portugal. Data were collected through a questionnaire on oral health behaviors, socioeconomic data, general health characteristics, self-perceived oral health and oral health-related quality of life. The oral clinical assessment included the Oral Hygiene Index-Simplified (OHI-S), the Decayed, Missing and Filled Teeth Index (DMFT), the Modified Community Periodontal Index, the presence of oral mucosal lesions, prosthetic presence, and prosthetic and treatment needs. Statistical analysis included descriptive and inferential methodologies. The association between potential risk indicators and oral health behaviors was assessed and modelled using logistic regression analysis. Results: A sample of 302 older adults participated in this study, and 56.0% were female. The mean age was 73.5 years (±5.8). Regarding oral health behaviors, 21.9% brushed less than twice a day, 52.1% did not use interdental devices and 49.3% last visited a dentist for treatment. Risk indicators for less frequent brushing were being male [OR = 3.00, 95% CI (1.65-5.47)], having a perceived prosthetic need [OR = 3.46, 95% CI (1.72-6.95)] and increased values of DMFT [OR = 1.15, 95% CI (1.08-1.22)]. Risk indicators for not using interdental devices were increased values of OHI-S [OR = 2.41, 95% CI (1.71-3.40)], being male [OR = 2.31, 95% CI (1.38-3.89)] and the presence of chronic diseases [OR = 1.87, 95% CI (1.03-3.39)]. Risk indicators for treatment being the reason for the last dental appointment were prosthetic presence [OR = 3.23, 95% CI (1.79-5.82)] and increased values of DMFT [OR = 1.06, 95% CI (1.01-1.11)]. Conclusion: Assessment of oral health behaviors and associated factors should be considered to guide future public health strategies to improve compliance with oral health care among older adults and to prevent oral diseases.
