Evaluating the effectiveness of various teaching methods on dental plaque removal in children: a quasi-experimental study.
Trial report in BMC pediatrics, 2025. 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
objectiveDental plaque is a major contributor to oral diseases, particularly in children, but its impact can be significantly mitigated through targeted oral health education. This study aimed to evaluate the effectiveness of various tooth-brushing instructional methods in reducing dental plaque in children.
methodsA total of 120 children, aged 6 to 8, attending the pediatric department of Alborz Dental School, were randomly selected for the study. Participants were divided into four groups of 30 children each (15 boys and 15 girls). Each group received a different instructional method: (1) demonstration of tooth brushing on a dental model, (2) self-brushing in front of a mirror, (3) brushing another child's teeth in front of a mirror, and (4) instruction via a standardized video. Dental plaque levels were measured using a disclosing agent before and after training, with a two-week follow-up to assess the impact of instruction. Senior students provided group-specific brushing training. Data were analyzed using SPSS-22 with ANOVA and t-tests, with significance set at p < 0.05.
resultsAll four groups demonstrated significant reductions in plaque levels post-training and at the two-week follow-up compared to baseline, as measured by the O'Leary index. The group trained with dental models showed the most substantial plaque reduction (p < 0.001).
conclusionInstruction using dental models proved to be the most effective and sustainable method for reducing dental plaque in children, highlighting its potential for impactful and enduring oral hygiene education.
