Background: Healthcare professionals, particularly the dental personnel have a higher risk of infection of COVID–19 due to the risk of inhalation of aerosolized particles. Aim: To assess knowledge and analyze the effectiveness of audio–visual (AV) aid on Personal Protective Equipment (PPE) among dental students. Materials and methods: A cross–sectional survey was conducted using google forms among dental students. The first part of the questionnaire comprised of 250 participants which assessed the knowledge whereas the second part consisted of 200 participants which analyzed the effectiveness of AV aid on PPE. Data obtained was analysed using SPPS IBM software version 19.0, Chicago. Results: Overall the knowledge among the dental students on PPE was poor. It was found that 84.4.% of the dental students were not confident to handle it and 83.2% never had experience to use the same. More than half of the dental students had misconception on the steps of using PPE and mere 17.2% had the right practice on the steps in doffing. Only 44.8% of the students were aware of five moments in hand hygiene. It was found that PPE was not included in the curriculum of 88% students. Over 93% students had a clear view of handling PPE after watching AV tool and it was highly encouraged instead of chalk and talk in the teaching system. Just 23% of the students utilised government websites to get updated. Conclusion: It is important to improve the knowledge of the dental students on PPE through continuing education programs using AV aids.
