A Randomized Crossover Clinical Trial Investigating 16-Branched Filament Toothbrush Effects on Dental Plaque Removal.
Trial report in Clinical and experimental dental research, 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
objectivesSelf-care using an appropriate toothbrush is important for oral health management. The aim of this clinical trial in older adults was to evaluate the effectiveness of a prototype toothbrush with 16-branched filament ends (16-BFE) in dental plaque removal compared to a toothbrush with super tapered filament (STF). MATERIAL AND
methodsFifty older adults in Japan (13 males and 37 females, mean age 70.8 ± 8.7 years) with 20 or more teeth were enrolled in this study. Participants were divided into Group A (26 subjects) and Group B (24 subjects) and a randomized crossover clinical trial was conducted. Intervention Study I was performed for 3 min using a prototype 16-BFE toothbrush. Dental plaque accumulation areas and gingival abrasion areas were measured before and after brushing by staining with MIRA-2-Ton. Intervention Study II was conducted in the same manner using an STF toothbrush. Crossover design was as follows: Group A was followed by an intervention study from I to II, while Group B was from II to I, with a washout period of 2 or 3 months. Analysis was performed using a modified PCR method (six sections of one tooth surface).
resultsThe average dental plaque removal rate using a 16-BFE toothbrush was 22.4%, which was a significant reduction compared to 18.5% of the STF toothbrush (p < 0.05). There was only one small area out of 1700 areas examined regarding gingival abrasion when using a 16-BFE toothbrush.
conclusionThese results suggested that the 16-BFE toothbrush provided a more effective way in dental plaque removal when compared to the STF toothbrush and was less harmful to the gingiva. Even though 16-BFE showed a significant improvement, clinical relevance and long-term effects needed to be further investigated.
