Effects of different energy levels of Er: YAG laser-assisted bleaching on teeth bleaching efficacy and immediate resin bonding: a study on safety and clinical applicability.
Article in Lasers in medical science, 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
purposeThe study aimed to evaluate the teeth bleaching effect of Er: YAG laser at different energy levels and its impact on immediate resin bonding shear strength. MATERIALS AND
methods72 human premolar teeth were randomly divided into six groups. Group A served as the blank group without any treatment, while Group B underwent teeth bleaching using a 37% hydrogen peroxide gel. Groups C, D, E, and F received the same 37% hydrogen peroxide gel for bleaching with additional Er: YAG laser radiation at energy levels of 40 mJ, 60 mJ, 80 mJ, and 100 mJ respectively. After completing the bleaching process, resin bonding was immediately performed in each group followed by measuring the shear strength.
resultsThe results showed that Er: YAG laser energy levels below 40 mJ did not enhance teeth bleaching compared to Group B; however significant differences were observed when comparing Group B with Groups D-F. Shear strength test results indicated no significant differences among experimental groups. These findings suggest that Er: YAG laser radiation can improve teeth bleaching effectiveness without affecting immediate resin bonding shear strength.
conclusionThe energy level of Er: YAG laser (40, 60, 80, and 100 mJ) significantly correlates with teeth bleaching, particularly at energy levels above 40 mJ, without compromising immediate resin bonding strength. These findings support the safe and effective use of Er: YAG laser-assisted bleaching in clinical practice, providing a practical parameter for clinicians to achieve desirable aesthetic outcomes.
