Association of Fear and Annoyance with Acoustic Levels of Dental Equipment Among Adolescents Attending Rural Dental Health Center: A Cross-sectional Study

Abstract

Introduction: Noise is increasingly becoming pervasive in occupational health concerning practicing dentists as well as patients. A stimulus such as noise from dental equipment compared to anxiety is often multifactorial and can result from a combination of fear of pain, dental instruments noise, or even upcoming negative events and future threats. Aim: This study aimed to assess fear and annoyance levels among adolescents attending a rural dental health centre and compare the acoustic noise levels of dental equipment and its association with fear and annoyance levels among adolescents. Methods: The acoustic noise spectra originating from different tools/equipment in a rural dental health centre is assessed using an application named sound meter of a standard mobile android phone (Samsung galaxy grand 2). Following a 15-minute treatment, a questionnaire was filled by a professional investigator through personal interviews with all subjects. The data is subjected to analysis by Statistical Package for Social Sciences version 22.0. Results: 61.5% of the subjects felt anxious about the anticipatory dental visit, and there was a significant difference observed between genders. Chi-square analysis revealed no significant differences in the fear and annoyance with increasing noise levels in various treatment groups. (p> 0.05). Conclusion: In the present study, fear and annoyance levels increased with increasing noise levels of equipment. Annoyance was found to be significantly higher in females.
