Knowledge level of diagnostic procedures and risk factors for oral cancer among oral healthcare providers in Germany.
Observational study 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
backgroundOral cancer is an underestimated and growing public health problem. The majority of cases are diagnosed at a late stage, even though oral cancer can be detected early by routine visual and tactile examination. Dental healthcare providers thus play a vital role in its early detection. This study assessed dental healthcare providers' knowledge of diagnostic procedures and risk factors for oral cancer.
methodsA cross-sectional, observational study was conducted using a validated survey of 38 items focusing on knowledge of diagnostic procedures and risk factors, and questions on continuing education. From October to December 2023, the online survey invitation was sent via all German state Dental Associations to their members. Participants' socio-demographic data and responses in the "knowledge, opinion and continuing education" section were analysed descriptively. Linear regressions assessed the associations between participants' characteristics or opinions and their knowledge of oral cancer (knowledge score).
resultsOverall, 8,132 participants began the survey. After filtering for reliability and completeness, data from 3,458, 3,472, and 2,933 participants were available for "socio-demographics", "knowledge", and "opinions and continuing education", respectively. Most participants were women (60%), between 30 to 49 years old (48%). The majority knew the most common type of oral cancer and the most common lesions associated with it. Furthermore, almost 89% of the participants were aware that early detection improves survival rates. The main risk factors (tobacco, alcohol, prior oral cancer) were well known. However, the potential for improvement in knowledge of localisation, signs, stage of diagnosis and the specific age group at risk was noted. Fewer years in the dental profession and since attending the last continuing education course were associated with higher levels of knowledge.
conclusionsKnowledge of localisation, signs, stage of diagnosis, and specific risk groups can be improved. These topics should thus be integral to the dental curriculum and addressed through structured continuing education programmes, as the study's results suggest that knowledge declines over time without continuing education.
