Changes in Color Stability and Surface Roughness of Teflon-Coated Arch Wires After Clinical Use.
Article in Turkish journal of orthodontics, 2022. 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
objectivePeeling of polytetrafluoroethylene (Teflon)-coated esthetic arch wires results in rough surfaces that may cause plaque accumulation, and the exposed core material may not meet the esthetic expectations of patients. The aim of this study was to evaluate the in-vivo surface roughness, Streptococcus mutans colonization, and color stability of Teflon-coated arch wires from 3 different manufacturers.
methodsSurface roughness and color data of 0.016-inch and 0.016 × 0.022-inch Teflon-coated arch wires from 3 different manufacturers were recorded as they were received (T0) and after 28 days of clinical exposure (retrieved) (T1) using an atomic force microscope and a spectrophotometer. The amount of S. mutans was assessed in terms of colony-forming units on the as-received and retrieved wires.
resultsThe surface roughness increased significantly, and a clinically noticeable color change was observed in all groups after clinical use (P < .005). There was no statistically significant difference in the amount of S. mutans adhesion for most of the wires. No significant correlation was found between the amount of S. mutans adhesion and the surface roughness.
conclusionAll the arch wires showed increased surface roughness and clinically noticeable color change. The surface roughness values were not found to be correlated with the amount of S. mutans adhesion.
