Comparing auditory vs. virtual reality relaxation in reducing dental anxiety.
Article in Frontiers in dental medicine, 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
Background: Up to 20% of American adults experience dental anxiety, creating a psychological and physiological barrier to starting, completing, and/or finishing dental treatment. There is a clear need for novel approaches to mitigate chair-side anxiety, especially for endodontic treatment appointments. This study aimed to investigate two nonpharmacological dental anxiety management approaches: (1) A brief auditory-alone relaxation (ABR) period and a brief virtual reality relaxation (VRR) period, and their hypothesized effects on patients' perceived dental anxiety and physiological biometric scores. Materials and methods: Fifty-eight participants who needed nonsurgical root canal treatment were assigned randomly to two groups: ABR or VRR. One group received earphones to listen to a guided, brief relaxation recording that incorporated conscious, diaphragmatic breathing and a guided body scan. The other group received Meta Quest 2 virtual reality headsets to listen and watch 360° inclusive and integrative experiences of ambient music, high-resolution graphic illustrations, and immersive scenery. The participants' self-reported levels of anxiety were assessed before and after treatment after they completed the State Trait Anxiety Indicator (STAI-State & Trait) and visual analog scale (VAS) scales. Additionally, biometric traits such as heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were measured before (T0), during (T1), and after (T2) treatment. Results: Both VRR and ABR significantly decreased anxiety, as reported by the STAI-State questionnaire ( Conclusion: This is the first study to investigate the effects of ABR and VRR on dental anxiety. Both the ABR and VRR groups presented significant reductions in anxiety, pain, and heart rate after treatment. Our study demonstrated that nonpharmacological techniques, such as ABR and VRR, can be valid, noninvasive approaches to reduce anxiety before dental treatment, specifically endodontic therapy. However, given the small cohort in this study, it will be necessary to reproduce the methods with a larger cohort and different types of ABR and VRR applications to confirm the effects of nonpharmacological interventions on reducing endodontic dental anxiety.
