Comparative evaluation of quantitative color changes in discolored anterior teeth by bleaching, resin infiltration, and microabrasion: A randomized clinical trial.
Article in Journal of conservative dentistry and endodontics, 2025. 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
Objective: This study aims to evaluate and compare the effects of bleaching, microabrasion, and resin infiltration (RI) techniques on discolored vital anterior teeth. Materials and Methods: Patients with anterior vital teeth with brown discolorations were selected for this study. The sample size was estimated at 15 teeth per group and assigned according to the treatment done: Group 1 (microabrasion), Group 2 (microabrasion and RI), Group 3 (microabrasion, bleaching, and RI), Group 4 (bleaching and RI), and Group 5 (bleaching). Standardized photographs were taken at the preoperative visit (T1), immediately after treatment (T2), and during the follow-up visit after 1 week (T3), and at 6 months (T4). The photographs were analyzed using (L* a* b*) values with the help of Adobe Photoshop 2021 software to show the assessment of values. Respective values were used to evaluate a quantitative evaluation of color change (ΔE). Results: The highest value change (ΔE = 20.72 ± 3.06) was seen in Group 3 which was statistically significant, suggesting that microabrasion and bleaching followed by RI offer better results than the other groups. Conclusion: Combining microabrasion, bleaching, and RI techniques offers the best treatment outcome for tooth discolorations among all groups.
