Impact of video instructions and additional hands-on instructions on the dental flossing performance - an observational study.
Trial report in Clinical oral investigations, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectivesThis study aimed to evaluate the effectiveness of an instruction-video, with and without additional hands-on instruction, in teaching young adults proper flossing performance. MATERIALS AND
methodsThis randomised intervention and observational study included 94 participants, 24 (23; 25) years, receiving an instruction-video with (group 1) or without additional hands-on instruction (group 2). The flossing performance was assessed by videotaping before instruction (T1), after instruction and one week of practice (T2), as well as after two weeks of practice (T3). Parameters of interest were number of interdental spaces reached, adaptation to mesial and distal surfaces, flossing technique, systematic approach and handling combined with self-assessment of flossing skills and time spent, assessed by questionnaires.
resultsAdditional hands-on instruction did not lead to a significant improvement in any parameter compared to video-instruction alone. At T1, the participants reached many interdental spaces, but only two managed to floss their entire dentition correctly. After video instruction (T2), the participants reached more interdental spaces (p = 0.039) using a systematic approach and improved adaptation, technique and handling (p < 0.001 each). Parameters improved again at T3, resulting in 42 participants flossing their entire dentition correctly. After instruction participants found flossing less difficult, although they estimated it took more time.
conclusionVideo-instruction significantly improved flossing performance, whereas hands-on instruction had no additional benefit. This indicates that video-instruction could be an effective and timesaving tool to improve flossing performance. CLINICAL RELEVANCE: The results emphasize the importance of appropriate teaching-methods in dental prophylaxis and highlight the potential of video-instructions to improve interdental cleaning skills significantly.
