Perceived preparedness and educational gaps in post-exposure prophylaxis among dental students in Saudi Arabia: a nationwide survey.
Article in BMC oral health, 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
backgroundDental professionals are at increased occupational risk of exposure to blood-borne pathogens such as human immunodeficiency virus, hepatitis B virus, and hepatitis C virus. Post-exposure prophylaxis is essential for preventing infections following exposure; however, dental students’ knowledge and adherence to post-exposure prophylaxis protocols remain uncertain. MATERIALS AND
methodsA survey of 962 undergraduate and intern dental students from 19 public and private dental colleges in Saudi Arabia, evaluated PEP knowledge, perceptions, and practices using an online questionnaire. Data were analyzed using appropriate statistical methods.
resultsOnly 46.4% of participants met the predefined ≥ 60% knowledge threshold for post-exposure prophylaxis, with many misconceptions identified. While 73.6% had a positive view of post-exposure prophylaxis, only 38.5% had formal training. Many rated their knowledge and confidence highly but perceived the dental curriculum as insufficient. Factors like gender, prior training, and clinical experience were linked to better post-exposure prophylaxis knowledge, highlighting the need for mandatory education.
conclusionGaps in post-exposure prophylaxis knowledge and training persist among dental students in Saudi Arabia, despite generally positive perceptions. These findings highlight the urgent need for standardized and mandatory post-exposure prophylaxis education to improve occupational safety.
