Impact of Different Cleaning Protocols on the Optical and Morphological Properties of 3D-Printed Aligners After In Vitro Aging.

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
Objectives: In-house printing of clear aligners (CAs) may represent a new revolution in CA therapy, providing a solution for the several limitations associated with indirect manufacturing. This study compared the changes in surface roughness and light transmittance (T%) of directly printed (DP) and thermoformed (TF) CAs after exposure to Materials and Methods: A total of 48 aligners were fabricated using either multilayer thermoplastic polyurethane (CA Pro + , Scheu Dental; Iserlohn, Germany) or direct three-dimensional-printed resin (Tera Harz TC-85, Graphy; Seoul, Korea). CAs were aged Statistical Analysis: Data analysis included descriptive statistics, independent Results: Compared with the DP aligners, the TF aligners presented greater T% under all conditions, with the highest T% in the as-received condition. The TF and DP aligners showed the lowest T% in ultrasonic cleaning and control conditions, respectively. When excluding the as-received group, most cleaning methods showed statistically significant differences in T%. The surface roughness of the TF aligners was consistently lower than that of the DP aligners, with significant differences observed between the Polident and control groups. Conclusion: Cleaning methods altered the optical and morphological properties of both aligners. Customized cleaning methods are required for CAs.
