Controlling Gag Reflex During Endodontic Diagnostic Radiography

Intraoral radiography plays a vital role in endodontic diagnosis and treatment planning. However, many patients experience discomfort during periapical radiographic procedures due to factors such as a pronounced gag reflex and dental anxiety, making the process difficult and distressing. Managing these issues is essential for enhancing patient cooperation and improving overall treatment experience. This study investigates the potential of Virtual Reality (VR) interactive distraction as a noninvasive method to control gag reflex and improve patient comfort during intraoral radiography. While VR has shown promise in reducing dental anxiety in various procedures, its effectiveness in managing gag reflex during diagnostic endodontic radiography remains largely unexplored. The primary objective of this study is to evaluate the effectiveness of VR in reducing the gag reflex in adult patients undergoing routine periapical radiographs for maxillary molar teeth. Secondary objectives include assessing patient preferences, experiences, and satisfaction associated with the use of VR. The study involves patients who require bilateral intraoral diagnostic radiographs of maxillary molars. Each patient will undergo two radiographs: one with standard procedure (Control - Group 1), and the other using VR distraction (Experimental - Group 2). A randomized, computer-generated list will determine which side will receive the VR intervention. Gag reflex scores will be measured before and after the procedure, pre- and post-procedure anxiety levels will be recorded using Modified Dental Anxiety Scale (MDAS). Additionally, a structured questionnaire will assess patient satisfaction and experience with the VR device. Physiological indicators such as pulse rate, blood pressure, and oxygen saturation will be recorded to evaluate any changes associated with the use of VR. This study aims to generate evidence on whether VR distraction can be an effective tool for controlling gag reflex and improving patient tolerance, ultimately enhancing the quality of care in diagnostic dental radiography.
