Efficacy of Submucosal Polydeoxyribonucleotide Injection after Impacted Mandibular Third Molar Extraction: A Randomized Controlled Trial.
Trial report in Yonsei medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
purposeThis study aimed to evaluate the efficacy of polydeoxyribonucleotide (PDRN) injection after impacted mandibular third molar (IMTM) extraction. The primary outcome was postoperative pain, while secondary outcomes included postoperative swelling, periodontal pocket depth, and patient-reported outcome. MATERIALS AND
methodsThirty medically uncompromised patients who underwent bilateral extraction of IMTMs were enrolled in the clinical study. PDRN was randomly injected on the experimental side, while normal saline was injected on the control side. Postoperative pain was assessed using a visual analog scale. Postoperative swelling was evaluated via linear measurements based on the Laskin method. Furthermore, three-dimensional volumetric analysis was conducted by superimposing serial facial scans obtained at baseline (preoperatively) and on postoperative days 3 and 7. Pocket probing depth was evaluated using a periodontal probe. Patients' postoperative morbidity and subjective perceptions were evaluated using the patient-centered outcome questionnaire. Statistical software was used to evaluate the data, and
resultsPatients demonstrated statistically meaningful reductions in postoperative pain, swelling, and discomfort on the experimental side.
conclusionThe results suggest that PDRN injection can be a suitable option to mitigate postoperative complications after IMTM extraction. However, further randomized controlled trials are required to confirm the reliability of the study and verify its suitability.
