Sealing Ability of Polydopamine-Coated Gutta-Percha With Bioceramic Sealer: An In Vitro Study.
Article in International journal of dentistry, 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
Rationale: Achieving a three-dimensional seal of the root canal system is essential for successful endodontic treatment. However, the hydrophobic nature of gutta-percha may compromise the interaction with the hydrophilic bioceramic sealers, leading to interfacial gaps and potential microleakage. Polydopamine (PDA) surface modification has recently emerged as a bioinspired strategy to enhance surface wettability and adhesion of biomaterials. Aim: To evaluate the sealing ability, adaptability, and wetting ability at the sealer-gutta-percha interface of PDA-coated gutta-percha cones with bioceramic sealer using the single-cone obturation technique. Methods: Sealing ability was assessed by measuring the apical dye penetration. Fourteen extracted mandibular premolars were instrumented using ProTaper Next rotary system, then randomly assigned into two groups ( Results: In the sealing ability test, PDA-coated gutta-percha demonstrated significantly lower dye penetration (3.04 ± 0.59 mm) than the uncoated gutta-percha (4.3 ± 1.11 mm) ( Conclusion: PDA surface modification significantly improved the wettability, interfacial adaptation, and the sealing performance of the gutta-percha when used with a bioceramic sealer. Clinically, this bioinspired coating may contribute to the quality and durability of root canal obturation.
