Introduction: PPE helps health care professional from exposure by preventing occupational exposure from various highly contagious viruses like Ebola Virus, SARS (Severe Acute Respiratory Syndrome), and novel coronavirus infection (COVID-19) and helps them to treat when working in a dental operatory or quarantine facility. PPE is used by healthcare professionals, supporting staff, laboratory staff, family members of patients, and situations where contact with blood, body fluids, secretions, or excretions is highly contagious and infectious diseases. PPE acts as a physical barrier between Microorganisms and Health care professionals and protects by preventing microorganisms from contamination of hands, eyes, clothing, hair and shoes.
Materials and methods: A questionnaire-based survey consisting of 10 questions with multiple choices is framed using Google forms by (Google LLC). The demographic data, knowledge-based, and attitude-based sections of the questionnaire were separated. The study subjects' participation was completely voluntary, and no personal information was taken from them. The subjects' willingness to engage in the study was based on their informed consent.
Results: This survey was done to assess the knowledge, attitude and practice regarding the use of PPE during emergencies. This survey enables the reader to better understand the precise and indispensable usage of PPE during health emergencies. Within the limitations of the study, it shows that knowledge concerning Personal Protective Equipment (PPE) is Moderate, compared to attitude and practice among respondents.
Conclusion: It is recommended that CDE programmes, Hands-on courses, and webinar programs be conducted for dentists to increase their awareness and gain more knowledge about the usage of personal protective equipment.

PPE helps health care professional from exposure by preventing occupational exposure from various highly contagious viruses like Ebola Virus, SARS (Severe Acute Respiratory Syndrome), and novel coronavirus infection (COVID-19) and helps them to treat when working in a Dental operatory or quarantine facility. PPE is used by healthcare professionals, supporting staff, laboratory staff, family members of patients, and situations where contact with blood, body fluids, secretions, or excretions is highly contagious and infectious diseases. PPE acts as a physical barrier between Microorganisms and Health care professionals and protects by preventing microorganisms from contamination of hands, eyes, clothing, hair and shoes. Gloves, protective eyewear (goggles), mask, apron, gown, boots/shoe cover, and hair cover are examples of PPE.
The dental operatory poses a riskier environment because of the high possibility of cross-infection between dental practitioners and patients by aerosol procedures. A study on personal protective equipment use among health care providers in Tamil Nadu by Archana Lakshmi P. A.in 2018 concluded that inappropriate use and lack of adequate knowledge on infection control practices emphasizing that periodic retraining is needed.
A COVID-19 positive case can go symptomless for many days; therefore, various guidelines are recommended by the Centre for Disease Control and Prevention (CDC) and World Health Organization (WHO) for dental health care workers. Adequate precautions must be taken; the exact behaviour of the virus is not fully understood by the scientists, making it even riskier for a health practitioner. There have been peaceful protests worldwide by doctors, nurses, and other healthcare professionals demanding PPE [1].
Highly infectious diseases and their exposure to contaminated body fluids, in healthcare staff. It reviewed contemporary evidence on ‘which type of PPE and which method of donning or doffing PPE protocol have the least risk of contamination or infection for Health care workers, and which training methods would increase compliance with PPE protocols. The evidence from this review is of great importance whereas the risk of infection, and even though COVID-19 is not considered a high consequence disease in the UK. Its findings remain relevant to the current pandemic and continue to be updated.
There are numerous studies regarding the use of PPE by Health Care Officials; many of the studies are regarding use in Medical; there are few studies regarding PPE use in Dental clinics. The knowledge awareness and practice among dentists use personal protection equipment during health emergencies or during pandemic situations in Chennai, Tamilnadu, India.
Study characteristics
The current study was a cross-sectional (questionnaire) descriptive study. Ethical clearance was given from the Institutional Human Ethical Committee of Saveetha Dental College and Hospital, SIMATS, Chennai, Tamilnadu, India. The survey was conducted in May 2020 among General dentists, Postgraduate students, and Dental specialists to assess the knowledge, attitude and practice regarding the use of Personal Protection Equipment during Health Emergencies or during Pandemic Situations in Chennai Tamilnadu, India. A questionnaire-based survey consisting of 10 questions with multiple choices is framed using Google forms by (Google LLC). The demographic data, knowledge-based, and attitude-based sections of the questionnaire were separated. The study subjects' participation was completely voluntary, and no personal information was taken from them. The subjects' willingness to engage in the study was based on their informed consent. Statistical analysis was done using descriptive statistical analysis. SPSS software version 23.0 by IBM was used to analyze the results statistically [2]. The information gathered was entered into excel sheets. Bar graphs and pie charts were used for pictorial representation of the result of the study.
A total of 104 responses were received from the respondents. Among 104 responses, 44 are female, and 60 are male, of which 22 are a general dentist, and 82 are specialists, and 21.16% of the participants had a professional experience within five years, whereas 78.84% of the participants had a professional experience of more than five years as shown in Table 1.

Depending on participants attitude regarding attending any courses regarding PPE use and disposal shows that 76.92% of respondents have not attended any course, while 23.08% of respondents have attended courses regarding usage and disposal of PPE [4-7]. Regarding donning and doffing protocol for PPE use shows that 59.62% of respondents know about donning and doffing protocol while 40.38% of respondents do not know about donning and doffing protocol for PPE use and regarding how much time it takes to wear PPE shows that 44.23% respondents take 10-15 minutes to while PPE and 43.27% respondents take 5-10 minutes and 12.50% respondents take 15-20 minutes to wear PPE (Figure 4).

Comparing medical and dental health care professionals, we found that knowledge scores were significantly higher in medical professionals. Attitude and practice score was found to be significantly higher in dental professionals. A multinational study found dentists to have good knowledge and practice scores, which is vital to combat health emergencies like COVID-19.
PPE should be considered after a risk assessment and as just one issue in a more effective preventive approach, including aerosol, droplet and splatter reduction and ventilation. Risk reduction must be considered along with other significant challenges to our staff’s health and wellbeing, including the nature of care and the complex business of dentistry. We do not have all the answers about universal precautions for the future, but all dental professionals will need to identify and manage risk in line with national guidance and learn from our colleagues worldwide. We have to justify our actions in managing risk, collect evidence, and be prepared to adapt where necessary.
Blue M can be used as a safe alternative to chlorhexidine in reducing the microbial load after the placement of implants. There was a promising result in reducing the bacterial load very similar to chlorhexidine. But when compared to each other there wasn't a significant change between them. Chlorhexidine has the edge in being very cheaper compared to Blue M. Further studies are required with conclusive evidence to be able to determine whether oxygen enriched mouthwashes can replace chlorhexidine in the future.
• Limited to a small number of responders; hence, it cannot be used to a wide population.
• Web-based surveys are inaccessible to challenging respondents who may lack access to the survey.
• Online surveys might lead to sampling problems.
• Online surveys might lead to sampling problems.
• In future, a larger population, particularly for a specific speciality/age/experience group.
• among dentists should be studied.
