Efficacy of 3D-Printed Cleaning Splints for Approximal Dental Biofilm Removal-A Randomized Clinical Crossover Pilot Study.
Trial report in Clinical and experimental dental research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 investigated the effectiveness of biofilm removal using individually customized cleaning splints (CS) as an aid for interdental brushes (IDBs). MATERIALS AND
methodsIn a randomized clinical crossover study, the effect of IDBs in combination with CS on plaque reduction and periodontal parameters was examined. Periodontitis patients received an intraoral scan to produce a 3D-printed CS. Following a 2-week interdental hygiene pause, they were divided into two groups: Group A: CS+IDBs, Group B: IDBs. Participants performed daily interdental cleaning at home for 2 weeks following standardized professional instruction. After another 2-week interdental hygiene pause, the groups switched methods. Additionally, motor skills, stress levels, and nutritional quality were assessed.
resultsThirty participants (age range 21-82 years) completed the study. CS+IDBs led to a significantly greater plaque reduction (change in Quigley-Hein plaque index, ∆QHI) compared to IDBs alone (ΔQHI = -1.38 vs. -0.23, p < 0.001). The impact on reducing gingival inflammation (GI) was limited to younger participants with no effect on bleeding on probing (BOP). Random effects ANCOVA confirmed the significant effect of CS on ∆QHI (p < 0.001). An interaction between perceived stress and CS use on BOP indicated that stress may influence the effectiveness of CS supported plaque removal.
conclusionsCleaning splints are a promising approach to enhance the effectiveness of IDBs in reducing interdental biofilm.
