Ozonated water to treat pericoronitis - insights from a randomized triple-blind pilot trial.
Trial report in BMC oral health, 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
backgroundPericoronitis, a painful inflammation of the soft tissues around a partially erupted tooth, is generally treated with debridement and saline irrigation. Ozone's antimicrobial and anti-inflammatory properties make it a promising adjunctive therapy.
aimTo evaluate the clinical effects and impact on quality of life of treating pericoronitis in lower third molars using ozonated water compared to physiological saline solution. MATERIALS AND
methodsThis study involved patients with pericoronitis in lower third molars, following CONSORT guidelines. Ethical approval was obtained from the UFVJM Research Ethics Committee (protocol number 5.922.185). Patients were divided into two groups: irrigation with ozonated water (OZO, n = 5) or saline solution (SAL, n = 5). The pain was assessed using a visual analog scale, and quality of life was evaluated using OHIP-14, OHIP14-PD Br, and SF-36 questionnaires. Evaluations were conducted at baseline, 24 h, and 3, 7, 15, and 30 days post-treatment. Clinical parameters assessed included probing depth (PD), bone crest level (BCL), mouth opening (MO), and extent of edema/erythema (EEE) in the pericoronal hood region. Plaque Index (PI), Bleeding Index on Probing (BOP), and lower third molar positioning were also evaluated using panoramic radiography.
resultsIntra-group analysis 7 days after treatment showed a significant reduction in pain (SAL: p = 0.018; OZO: p = 0.002) and the extent of edema/erythema (SAL: p = 0.002). OHIP-14 scores indicated significant intra-group differences at 30 days post-treatment (SAL: p = 0.043; OZO: p = 0.041).
conclusionOzonated water demonstrated similar efficacy to saline solution in managing pericoronitis, suggesting its potential as a viable alternative treatment. CLINICAL RELEVANCE: This study presents an alternative treatment option for pericoronitis. CLINICAL TRIAL REGISTER: This clinical trial was registered at the Brazilian Clinical Trials Registry (ReBec) under protocol RBR-79pss6w ( http://www.ensaiosclinicos.gov.br/rg/RBR-79pss6w/ ), Date of registration: 22/11/2024.
