Beyond failure: a case report on brain state changes during virtual reality-induced hypnosis in pediatric patient.
Article 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
backgroundManagement of fear in anxious patients is challenging, particularly in children. Virtual reality induced hypnosis may help during the procedures, changing vital parameters and brain states. Modifications in brain activity can be easily traced with wearable instruments. CASE PRESENTATION: An 11-years old boy was scheduled for avulsion of teeth 15 and 25, which were misplaced in the hard palate. Due to his fear of procedure, he was exposed to virtual reality-induced hypnosis. The brain state was continuously monitored, showing light sedation, associated to low spectral edge frequency values, below 20 Hz, indicating a relaxed/hypnotic state. In both sessions, the electrical activity was higher in the right hemisphere compared to the left, which is conceivable in hypnotic state. During the first session, a technical problem ensued, which was detected by the patient and readily managed with additional anesthesia. Despite the negative experience, one week later the hypnotic state was readily induced and tooth extraction was accomplished without any problem.
conclusionsVirtual reality-induced hypnotic state may be an easy and safe procedure to use with anxious patients even in pediatric age. If coupled to brain state monitoring, also adverse events can be promptly managed. In addition, hypnotic state may be induced also after the negative experience due to unexpected problems, prompting for the use of this technique in the dental setting also after initial, partial failure.
