Er:YAG Laser-Assisted Root Canal Decontamination in Post-treatement Endodontic Apical Periodontitis: A Case Report.
Article in Cureus, 2026. 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
Bacterial biofilm persistence in the endodontic system is often linked to post-treatment apical periodontitis, which continues to be a significant therapeutic problem. Because of their ability to penetrate and their photothermal effects on resistant microbes, laser technologies have shown great promise in enhancing root canal decontamination. The aim of this brief case report was to assess whether laser decontamination of the root canal system is beneficial for a patient who has persistent apical periodontitis following endodontic treatment. Clinical and radiographic examination of the patient's teeth revealed post-treatment chronic apical periodontitis at tooth 47, for which endodontic retreatment was indicated. Root canal irrigation was performed using 5.25% sodium hypochlorite, activated with an Er:YAG dental laser to enhance root canal disinfection. Efficacy was assessed using cone beam computed tomography images by comparing the initial and postoperative radiographic evolution. Radiologic assessment at three months confirmed a tendency toward apical lesion regression and clinical improvement, with no postoperative adverse events observed.
