The Effect of Exosomes Derived from Human Umbilical Cord Mesenchymal Stromal/Stem Cells on the Regeneration of Human Pulpectomized Tooth: A Case Report.

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
The dental pulp is essential for tooth health and sensory function. However, conventional treatments for infected or necrotic pulp, such as root canal therapy, frequently result in tooth loss and increased fracture risk. Regenerative endodontic procedures (REPs) aim to regenerate pulp tissue while preserving tooth vitality. Exosomes from human umbilical cord mesenchymal stromal/stem cells (hUCMSCs) demonstrated potential for tissue regeneration. In this case report, the potential of hUCMSC-derived exosomes for regenerating the dental pulp of a pulpectomized tooth was investigated. The patient, a 40-year-old man, was presented with irreversible pulpitis in the mandibular second premolar. The patient underwent a pulpectomy, followed by the application of a chitosan and hUCMSC-derived exosome mixture into the root canal. This project was conceived and executed as a joint project in Bushehr (Iran), Shiraz (Iran), and Aktobe (Kazakhstan) from 2022 to 2024. Exosomes were isolated and characterized using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Clinical evaluations, including visual inspection, palpation, pulp vitality tests, radiography, and cone beam computed tomography (CBCT) imaging, were conducted over 24 weeks post-treatment. The SEM and TEM images confirmed the effective isolation and characterization of exosomes. Clinical follow-ups showed no signs of infection, swelling, or tenderness around the treated tooth. Radiographic assessments indicated periapical radiolucency and periodontal ligament widening, suggesting active healing. Despite these radiographic changes, the absence of clinical symptoms indicated successful tissue regeneration and integration. This case report demonstrated the potential of hUCMSC-derived exosomes for dental pulp regeneration, with promising results in maintaining tooth vitality and promoting healing.
