Using AR and VR glasses to help children feel less pain and anxiety during local dental anesthesia

The Effect of Augmented Reality Versus Virtual Reality Glasses as Distraction Techniques in Children During the Administration of Local Anesthesia A Randomized Clinical Trial

Not applicable Interventional Ain Shams University · NCT07060170

This project will try augmented reality (AR) and virtual reality (VR) glasses to see if they help children aged 5–8 feel less pain and anxiety during local dental anesthesia.

What this trial studies

This single-center pediatric study compares augmented reality (AR) and virtual reality (VR) glasses as audiovisual distraction during local anesthetic injections in children aged 5–8. After an introductory visit to familiarize children with the dental environment and confirm cooperation, participants attend two treatment visits in which they wear AR or VR glasses (one type per visit) while receiving local infiltration anesthesia. Researchers will collect saliva for biomarkers (salivary alpha-amylase and cortisol) and continuously record vital signs such as heart rate and oxygen saturation before and after anesthesia to measure physiological stress and pain responses. The within-subject design allows direct comparison of the two distraction methods in the same child at the Pediatric Dentistry Department of Ain Shams University in Cairo.

Who should consider this trial

Good fit: Children aged 5–8 who are cooperative (Frankl behavior rating 3–4), healthy (ASA I), at normal weight for age, without anxiety disorders or prior local anesthetic exposure, and who need local anesthetic for deep caries in primary molars on both sides are ideal candidates.

Not a fit: Children with special health care needs, known anxiety or salivary gland disorders, those on corticosteroids, those who have previously received local anesthesia, or uncooperative children are unlikely to be eligible or to benefit from the tested interventions.

Why it matters

Potential benefit: If successful, these glasses could help children experience less pain and anxiety during dental injections, making visits easier and less stressful.

How similar studies have performed: Previous pediatric research has shown that virtual reality distraction can reduce procedural pain and anxiety, while augmented reality has been less extensively studied but shows early promise.
