“…In relatively closed environments with prolonged exposure to high concentrations of aerosols, the possibility of aerosol transmission cannot be ruled out [ 35 – 37 ]. Given that dental treatments generate a large number of droplets and aerosols carrying pathogenic microorganisms, there is a high risk of in-hospital spread and hospital infection [ 38 – 40 ].…”

Backgrounds Dental procedures involving drilling and grinding can produce a significant amount of suspended aerosol particles (PM) and bioaerosols. This study aims to analyze the size and concentration of aerosol particles generated during drilling and to investigate the effectiveness of two air exchange systems, namely forceful suction (FS) and air disinfection machines (DM), in removing PM. Methods For this study, 100 extracted permanent teeth were collected and divided into three groups: without suction (n = 50), suction with forceful suction (n = 25), and suction with air disinfection machines (n = 25). The removal rate of suspended aerosol particles was analyzed using particle counters and air data multimeter. Results When drilling and grinding were performed without vacuum, 0.75% of the aerosol particles generated were PM2.5-10, 78.25% of total suspended aerosol particles (TSP) were PM2.5, and 98.68% of TSP were PM1. The nanoanalyzer measurements revealed that the aerodynamic diameter of most aerosol particles was below 60 nm, with an average particle diameter of 52.61 nm and an average concentration of 2.6*1011 ultrafine aerosol particles. The air change per hour (ACH) was significantly lower in the air disinfection machines group compared to the forceful suction group. Additionally, the number of aerosol particles and mass concentration was significantly lower in the air disinfection machines group compared to the forceful suction group in terms of PM2.5 levels. However, the forceful suction group also reduced the mass concentration in PM10 level than the air disinfection machines group. Conclusion In conclusion, the air exchange system can reduce the aerosol particles generated during drilling and grinding. Comparing the two air exchange systems, it was found that the air disinfection machines group reduces the number of aerosol particles and mass concentration in PM2.5 levels, while the forceful suction group reduces the mass concentration in PM10 level.

“…The United Kingdom also has laboratory service of the British Public Health Service (Public Health Laboratory Service) to monitor the control of healthcareassociated infection (HAI). The main sponsor, which organizes assemblies dedicated to HAI, is the Hospital Infection Society (HIS), that publishes a globally significant and standard journal-the Journal of Hospital Infection [3]. HAIs need to be diagnosed and treated in time, but the most important thing is to maintain proper precaution in various hospital wards, especially in intensive care units (ICU) [4].…”

Pseudomonas Aeruginosa - New Perspectives and Applications

Pseudomonas aeruginosa is a Gram-negative bacillus that is ubiquitous. It is found in abundant amount in the environment, especially in moist places. Immunocompetent persons get less infected by P. aeruginosa, while immunocompromised patients get more infected by them. The burn patients, patients with cystic fibrosis, and patients who are dependent on any device like ventilator, intravenous catheter, or indwelling bladder catheter are more prone to acquire the infection. It is the main cause of ventilator-associated pneumonia. Patients with neutropenia are more susceptible to P. aeruginosa infections. P. aeruginosa has got several virulence factors through which they can cause disease. They have got attachment factors like Pilli and enzymes. They are one of the main pathogens of healthcare-associated infection (HAI). As P. aeruginosa is multidrug-resistant so this has got an extra contribution to the fact that they can cause HAI more. Common antibiotics like penicillin, carbapenems, cephalosporins, and all other Beta-lactam drugs along with aztreonams and fluroquinolones are resistant to P. aeruginosa. The proper maintenance of hand hygiene and continuous monitoring of hospital devices can lessen the burden of HAI associated with P. aeruginosa infection.
