Knowledge of COVID-19 and its implications in dental treatment, and practices of personal protective equipment among dentists: A survey-based assessment

Abstract

BACKGROUND: Oral health-care providers are always at a risk of transmitting or acquiring airborne, saliva-borne, or blood-borne infections due to their proximity to the patient s mouth, contact with saliva, and handling of sharp instruments. the aim this study was to evaluate the knowledge of the dentists regarding COVID-19, methods to prevent its transmission, and implications of COVID-19 in dental treatment. MATERIALS AND METHODS: It was a cross-sectional online survey. There were 35 questions in total, divided into sections of knowledge of COVID-19, practices of personal protective equipment (PPE), and knowledge of implications of COVID-19 in dental treatment. Both convenience sampling and snowball sampling were used, so that maximal participation could be ensured. The results were analyzed using descriptive statistics and making comparisons among various groups. The data were summarized as proportions and percentages (%). All the associations were tested using the Chi-square test, ANOVA, and Pearson s correlation coefficient. Statistical analyses were performed using SPSS version 19.0. RESULTS: 26.8% of respondents had a high knowledge, 61.5% had good knowledge, 10.1% had low knowledge, and 6 (1.5%) had nil knowledge about COVID-19. No significant association was found between qualification and knowledge level among the respondents (P = 0.053). Both graduates and postgraduates had low knowledge regarding effective PPE components (P = 0.053), donning (P = 0.888), and doffing (P = 0.745). Only 52.9% of postgraduates and 43.7% graduates answered correctly about the sequence of donning, and 47.9% of postgraduates and 46.1% of graduates had knowledge regarding correct doffing sequence of PPE. Furthermore, knowledge was low regarding the implications of COVID-19 in dental treatment. CONCLUSION: Although the dentists were found to have high/good knowledge scores regarding COVID-19, there was a lack of knowledge regarding hand hygiene, proper use of PPE, and implications of COVID-19 in dental treatment. Thus, they need to be trained and sensitized regarding the same.
