## TL;DR

This study assesses Indian dentists' knowledge of oral symptoms of COVID-19 and how pandemic waves affected dental practice.

## Contribution

The study combines survey and interview data to evaluate dentists' awareness and the pandemic's impact on dental protocols.

## Key findings

- Most dentists had good knowledge of basic details and oral manifestations of COVID-19.
- Strict infection control protocols were emphasized as necessary following the pandemic.
- Four key themes emerged from interviews about the pandemic's impact on dental practice.

## Abstract

The cross-infection created between dental staff and patients by COVID-19 had no established protocols for the dental problems caused by the pandemic. Hence, the dentists’ knowledge regarding the oral symptoms of COVID-19 were assessed.

This study reviewed the knowledge regarding oral manifestations of COVID-19 among dentists and the effect of waves 1 and 2 on dental community.

In phase I, a cross-sectional survey with standardised and validated questionnaire was distributed among dentists using social media. In phase II, a qualitative in-depth interview of 8 dental clinicians (samples due to data saturation) was done to investigate the effects waves 1 and 2 on dentistry. Descriptive data was analysed via chi-square tests and Phase II analysis was carried out via Atlas-Ti software.

About 84.4% dental surgeons, 15 (3.7%) BDS, 48 (11.9%) MDS aspirants had good knowledge about the basic details and the oral manifestations of COVID-19, and the results were statistically significant with the participants’ knowledge about COVID-19 (p = 0.001), oral manifestations (p = 0), recommended personal prevention (p = 0.01), the necessity of RT‒PCR (p = 0) and disease fatality (p = 0.015). In phase II, four themes were formed from interviews: Source of 1st information, Outlook towards COVID-19, Impact and Self-retrospection.

This study highlights the knowledge assessment among dental clinicians on the requirement of educational training programs about infection control practices to be followed in dentistry. The in-depth interviews of the dental clinicians revealed the need for strict infection control protocols following the pandemic.
