Feasibility Study of a Novel Stent-Based Low-Level Laser Therapy Device for Reducing Severe Radiation-Induced Oral Mucositis.

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
objectivesRadiation-induced oral mucositis (RIOM) is a severe complication of radiotherapy (RT) for head and neck cancers, impairing quality of life and treatment adherence. Low-level laser therapy (LLLT) shows promise for reducing RIOM severity, but operator-dependent devices limit practicality. This feasibility study assessed the safety and efficacy of a novel intraoral stent-based LLLT device designed for consistent laser delivery. MATERIALS AND
methodsThis prospective, single-arm, multicenter study enrolled 15 patients receiving curative RT for head and neck cancers. The stent-based device delivered laser light to 43 oral cavity points at three wavelengths (670, 830, and 910 nm) during 20-min sessions, five times weekly. The primary end point was the incidence of Grade 3 or higher RIOM (WHO oral mucositis scale). Pain severity was a secondary end point (Numeric Pain Rating Scale [NPRS]).
resultsGrade 3 or higher RIOM occurred in 6.6% of patients, significantly lower than historical rates (30%-40%). No patients reported severe pain (NPRS ≥ 8). The device was well-tolerated with no adverse effects, and all patients completed RT as planned.
conclusionsThe intraoral stent-based LLLT device is a safe and potentially effective intervention for reducing severe RIOM. Randomized trials are warranted to confirm these findings.
trial registrationThis study was a prospective, single-arm feasibility trial and was not registered in a clinical trial registry, as it did not meet the criteria for mandatory registration at the time of its initiation.
