Knowledge, Dental Anxiety, and Patient Expectations During the COVID-19 Pandemic

Abstract Objective: To assess the knowledge, dental anxiety, and expectations regarding dental services during the COVID-19 pandemic. Material and Methods: The respondents were Indonesian citizens above 18 years old. An online Google survey was administered using a structured questionnaire with a snowball sampling technique. Survey items comprised knowledge related to COVID-19, dental anxiety assessed using the modified DAS (Dental Anxiety Scale) and expectations regarding dental services using four dimensions of dental service quality. All questionnaires were tested for reliability and indicated acceptable and good agreement. The data were analyzed descriptively. Results: A total of 553 responses were analysed. Most respondents were female (72.9%), 76.7% knew of recommendations to postpone dentist visits and 86.8% knew methods of preventing COVID-19 transmission. More than 70% of respondents knew the precaution procedures in the dental office during COVID-19, and only 27.9% had moderate-severe anxiety. Most respondents' expectations regarding dental services during the pandemic era were related to the quality domain of reliability and responsiveness. Conclusion: Respondents knew about COVID-19 transmission and prevention, emergency conditions warranting a visit to the dentist and the procedures used at the dental office. Most respondents stated that they were not anxious about visiting a dentist during the pandemic. The respondents expect the dentist to provide sufficient information to improve oral health and treatment plan.

Quality of Tooth-Whitening Videos Available on YouTube

ABSTRACT Objective: To compare how the quality of YouTube videos on tooth whitening uploaded by healthcare professionals and laypersons. Material and Methods: The video that was uploaded in a year was collected on YouTube using the keywords tooth whitening and dental bleaching. The exclusion criteria were duplicate videos, advertisements, no sound, too short duration, and lectures. The variables analyzed were likes/dislikes, viewers, interaction index, viewing rate, usefulness, global quality scale (GQS), and comprehensiveness score. Two observers reviewed the videos independently. Data were analyzed descriptively and analytically. Results: A total of 106 videos were selected, and most were uploaded by laypersons (70.8%). The observer reliability test showed excellent agreement with the intraclass correlation coefficient score minimum of 0.876. There were significant differences in dislikes (p=0.003), views (p=0.016), interaction index (p=0.010), usefulness (p=0.030), GQS (p<0.0001), and comprehensiveness (p=0.014) between healthcare professionals and laypersons. Videos made by laypersons had higher numbers of dislikes and viewing rates, whereas healthcare professionals were higher in usefulness, GQS, and comprehensiveness. Conclusion: Videos uploaded by laypersons provide low-accurate information despite being popular among viewers. Viewers need to be selective in seeking information from YouTube as a resource for oral healthcare decision-related tooth whitening.
