High-Concentration Hydrogen Peroxide Gels Containing Calcium Polyphosphate Associated With Violet Led Light: Bleaching Efficacy and Effects on Enamel Properties.
Article in Journal of esthetic and restorative dentistry : official publication of the American Academy of Esthetic Dentistry ... [et al.], 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
objectivesTo evaluate the effect of violet LED light (VL) and hydrogen peroxide (HP) in-office bleaching gels supplemented with calcium polyphosphate (CaPP) or calcium gluconate (GU): MATERIALS AND
methodsBovine enamel blocks (n = 10) were randomly assigned: commercial HP gel, commercial HP gel with GU, or experimental 35% HP with or without CaPP (0.5 or 1.5 wt%), and their VL-irradiated versions. Bleaching efficacy was assessed by color analyses (CIE L*a*b*, ΔE
resultsThe group irradiated only with VL exhibited lower color change (p < 0.0001). CaPP addition significantly increased ΔE
conclusionsBleaching gels containing CaPP maintained bleaching efficacy and mediated enamel microhardness recovery. VL further enhanced the bleaching effect in CaPP gels. CLINICAL SIGNIFICANCE: CaPP represents a promising alternative for bleaching gel formulations, promoting enamel remineralization and enhancing bleaching efficacy when combined with VL.
