Modulating the periodontal wound microenvironment through oxygen therapy: a narrative review on the biological basis, clinical applications and future perspectives.
Review in The Saudi dental journal, 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
Topical oxygen-releasing formulations have emerged as a potential adjunctive approach to enhance wound healing outcomes in conditions such as gingivitis, periodontitis and peri-implant diseases. Periodontal wound healing is a complex biological process influenced by microbial load, tissue oxygenation, and host inflammatory responses. This narrative review aimed to evaluate the available clinical evidence on the effectiveness of topical oxygen-releasing products in oral soft and hard tissue wound management. Unlike previous broad reviews of topical oxygen therapy, this review specifically synthesizes its role in periodontal wound healing, compares clinical outcomes with conventional therapies, and evaluates emerging opportunities for integration into regenerative periodontal strategies. An organised literature search was conducted in PubMed, Scopus, Web of Science, and the Cochrane Library for studies published till 2025. Eligible studies included primarily randomized controlled trials, evaluating clinical outcomes related to periodontal wound healing. A structured search of five electronic databases was undertaken, and eligible studies were narratively synthesized in accordance with the Scale for the Assessment of Narrative Review Articles (SANRA). Included studies, were evaluated qualitatively to compare the efficacy of topical oxygen therapy as an adjunct in periodontal wound healing. The findings suggest that topical oxygen-releasing formulations provide adjunctive benefits in specific contexts, particularly in postoperative healing, periodontal therapy, enhancing soft tissue healing, and improving patient-reported outcomes such as pain and discomfort. However, many outcomes were comparable to conventional therapies such as chlorhexidine. Topical oxygen-releasing formulations appear to be a potential adjunct in periodontal wound repair, particularly in hypoxic or inflammatory conditions.
