Effectiveness of an educational program on improving the knowledge and practice of environmental sustainability in dentistry among undergraduate students at Faculty of Dentistry in Egypt: an interventional study.
Trial report 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
backgroundDental practices generate significant environmental impacts, necessitating environmentally sustainable dentistry (ESD) for equitable, ethical, and resource-efficient care. However, a knowledge gap exists among dental practitioners regarding sustainable practices.
objectivesThis study assessed the effectiveness of an educational program on the knowledge and practice (KP) of undergraduate dental students at Pharos University in Alexandria (PUA), Egypt, regarding ESD.
methodsThe study was conducted from April to November 2024 and recruited 175 final pre-clinical (3rd) and final clinical (5th) year students. Participants' KP was evaluated before, immediately after, and six months post-program using a structured questionnaire. Statistical analysis employed t-tests, one-way ANOVA, and univariate regression models.
resultsParticipants (58.28% female, mean age 20.88 years) initially demonstrated low awareness of sustainability, primarily relying on social media for information (37.14%). The program improved knowledge, increasing the mean percentage from (60.38% ± 17.74%) to (92.60% ± 7.42%) immediately post-program and (76.41% ± 21.66%) after six months (p < 0.001). Self-reported practices also improved, rising from (52.84% ± 10.79%) to (64.14% ± 11.73%) then (61.90% ± 13.47%) (p < 0.001). Participants with good KP increased from (12.57%, 1.14%) pre-program to (93.14%, 15.42%) immediately post-program, then (51.42%, 18.28%) after six months (p < 0.001). Moderate positive correlations were found between knowledge and practice post-intervention (p < 0.05). Regression indicated that prior awareness of sustainability strongly predicted better KP of ESD at baseline, also final clinical educational level predicted good knowledge and using social media/websites predicted good practice.
conclusionsBaseline KP regarding ESD was low. The educational program significantly enhanced participants' KP, demonstrating the potential of the multi-component targeted educational intervention in enhancing ESD. Incorporating sustainability into undergraduate curricula is recommended to improve future dental professionals' competencies.
