Effect of Excessive Washing and Frosty Appearance on Mechanical and Optical Properties of 3D Printed Restorative Material.
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. 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
objectivesTo evaluate the effect of the washing process on the mechanical and optical properties of a 3D printed resin indicated for indirect restorations and to determine possible solutions to reverse the negative effects of excessive washing.
methodsA 3D printed resin (Sprintray Ceramic Crown) was used to test three-point flexural strength, Vickers hardness, degree of conversion on the surface (DC
resultsExcessive washing (PC) resulted in a significant reduction in flexural strength, DC
conclusionExcessive washing resulted in lower flexural strength, surface hardness, degree of conversion, and translucency. Among different methods to reverse these negative effects, infiltration of fresh resin was the most effective method. CLINICAL SIGNIFICANCE: Excessive washing of 3D printed resin intended for long term indirect restoration in a pre-programmed washing unit resulted in a significantly weaker and more opaque material, resulting in compromised clinical performance of the material and potentially lower light penetration for curing of the resin cement. Infiltration of fresh resin was an effective method to regain mechanical and optical properties.
