Optimizing resin bonding to saliva-contaminated polyetheretherketone: comparative efficacy of cleaning methods.
Article in BMC oral health, 2025. 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
backgroundThis study investigated the effects of saliva contamination and different cleaning protocols on the surface characteristics and bonding performance of polyetheretherketone (PEEK).
methodsA total of 120 PEEK specimens were divided into six groups: uncontaminated (UN), contaminated without cleaning (S), and contaminated followed by cleaning with Ivoclean (IC), Katana Cleaner (KC), ethanol (ALC), or sandblasting (BLA). Resin composite cylinders were bonded to the specimens, and shear bond strength (SBS) was evaluated before and after 10,000 thermal cycles. Surface properties (water contact angle, roughness) were analyzed.
resultsSaliva contamination significantly reduced SBS (P < 0.05), irrespective of aging. The IC and ALC groups showed significantly lower SBS than the UN group. In contrast, cleaning with KC or BLA effectively restored SBS to levels comparable with uncontaminated PEEK, under both aged and unaged conditions. Adhesive failure was the predominant failure mode. While contamination and cleaning reduced hydrophobicity (lower contact angles), surface roughness remained unchanged across groups.
conclusionsSalivary contamination impairs PEEK-resin bonding, but sandblasting or Katana Cleaner effectively restores bond strength. These protocols offer clinically viable decontamination strategies for PEEK-based restorations.
