Assessment of dental students' knowledge and attitudes regarding passive smoking and its effects on dental health.
Article in BMC medical education, 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
objectivePassive smoking is also called secondhand smoke (SHS) exposure remains one of the most important yet preventable threats to child health worldwide. Because dentists regularly encounter children and their caregivers, their contribution to household-level tobacco prevention depends on adequate professional training. This study aimed to evaluate dental students' knowledge and attitudes regarding the oral and dental health consequences of passive smoking, with emphasis on child health and preventive responsibility.
methodsThis cross-sectional study included 748 undergraduate dental students from first to fifth academic year at a public university in Türkiye. Participants completed a structured 16-item questionnaire assessing knowledge of SHS-related systemic and oral health effects, perceived educational sufficiency, and attitudes toward recording SHS exposure during patient anamnesis.
resultsOverall awareness of the harmful effects of passive smoking was high, but significant differences were observed across academic years. Third-year students demonstrated the highest proportion of correct responses, whereas first-year students showed the lowest, and total knowledge scores differed significantly between years (p < 0.001). Although 58.9% of students reported having sufficient knowledge, only a minority had received formal education on SHS, with the lowest rate among second-year students (17.2%). Most students agreed that SHS exposure should be routinely recorded and considered during treatment planning (p < 0.001).
conclusionsA clear gap exists between general awareness and structured education on SHS. Integrating comprehensive SHS-focused training into undergraduate dental curricula may strengthen child-centred tobacco prevention and enhance the role of dentists in reducing household tobacco exposure.
