Plain English summary of protocol

Background and study aims
Many children feel anxious or experience pain when receiving a local anaesthetic injection during dental treatment. Anxiety and pain can make dental visits more difficult for children, parents, and dental professionals. Virtual reality (VR) technology may help distract children during medical and dental procedures, reducing their discomfort and fear. This study aims to find out whether using a VR headset during a dental injection can reduce pain, anxiety, and distress in children compared with standard care.

Who can participate?
Children aged 4 to 10 years who are generally healthy, have not had dental treatment or visited a dental setting in the previous six months, and whose parent or guardian agrees to participation can take part.

What does the study involve?
After parents or guardians provide consent, participating children are randomly allocated to one of two groups. One group receives local anaesthetic injections while wearing a VR headset, while the other group receives the injection without VR. Before treatment, measurements are taken including pulse rate and behaviour scores. Additional measurements are recorded during and after the injection. Researchers assess anxiety using pulse oximeter readings, behaviour using validated behavioural scales, and pain using a child-friendly pain rating scale. The results from the two groups are compared to determine whether VR reduces anxiety, pain, and distress during dental injections.

What are the possible benefits and risks of participating?
Children using VR may experience less anxiety and discomfort during the dental procedure. The study may help identify effective ways to improve children's experiences of dental treatment in the future. Risks are expected to be minimal and are mainly related to the routine dental injection. Some children may find the VR headset uncomfortable or may not wish to use it.

Where is the study run from?
Faculty of Dental Medicine, Alaa Redwan, Umm Al-Qura University, Makkah, Saudi Arabia.

Health condition(s) or problem(s) studiedPain and anxiety during local anesthesia in pediatric dentistry
InterventionParticipants were randomly allocated to treatment groups using numbered, opaque, sealed envelopes to ensure allocation concealment. The first group received local anesthesia while using the VR device (intervention group) while the other received local anesthesia without the VR device (control group). The VR was placed for about 4-5 minutes depending on the child and the operator and that was only once during the LA insertion.
