Summary

This randomized controlled clinical trial aims to compare the effectiveness of virtual reality (VR) eyewear used as a distraction method in combination with the Show-Do (SD) technique versus the traditional Show-Do technique alone in managing dental anxiety and improving behavioral responses among Egyptian children with different levels of hearing impairment during a dental prophylaxis procedure. The study will evaluate dental anxiety using pulse rate and the PJS-Pictorial Scale, while behavior will be assessed using the Frankl Behavior Rating Scale. The trial seeks to provide evidence-based guidance on the implementation of VR technology as an adjunctive non-pharmacological tool for children with communication barriers in pediatric dentistry.

Detailed description

Dental anxiety is a common barrier to effective dental care in pediatric patients, particularly in children with special health care needs such as hearing impairment. Communication limitations can increase anxiety and reduce cooperation, complicating dental treatment delivery. Traditional non-pharmacological techniques such as the Show-Do (SD) method are widely used to reduce anxiety by familiarizing children with dental procedures through demonstration and gradual exposure. However, their effectiveness may be limited in children with hearing impairments, who may not fully understand auditory or verbal explanations. Virtual reality (VR) eyewear represents an innovative behavioral management tool that immerses the child in an interactive and engaging virtual environment, thereby diverting attention away from the dental procedure and reducing anxiety. Evidence from recent systematic reviews indicates that VR interventions can significantly decrease pain perception and anxiety in pediatric medical and dental settings, yet studies specifically targeting children with hearing impairment remain scarce. This randomized controlled trial will be conducted at the Pediatric Dentistry Department, Faculty of Dentistry, MSA University. Participants will include children with varying levels of hearing impairment requiring dental prophylaxis. Eligible participants will be randomly assigned in a 1:1 ratio to either the control group (Show-Do technique only) or the intervention group (Show-Do technique combined with VR eyewear). Dental anxiety will be measured objectively using pulse oximetry and subjectively using the PJS-Pictorial Scale, while behavior will be assessed using the Frankl Behavior Rating Scale. The study is designed to generate clinical evidence regarding the efficacy of integrating VR eyewear with conventional behavioral management methods for children with communication challenges. The results are expected to contribute to the development of inclusive, non-pharmacological strategies to manage dental anxiety and improve cooperation among pediatric patients with hearing impairments, ultimately enhancing patient-centered care in pediatric dentistry.
