“…Dental offices warrant special attention due to the generation of aerosols during various procedures [50]. Ultrasound scaling, a widely employed dental procedure, generates substantial aerosol quantities containing bacteria from the patient's saliva, gingival sulcus, or pocket, where the most pathogenic oral bacteria reside [51]. The research presented in this article revealed the methods of reducing and eliminating the number of bacteria in aerosols generated during dental procedures.…”

Molecular methods have become integral to microbiological research for microbial identification. This literature review focuses on the application of molecular methods in examining airborne bacteria and fungi in healthcare facilities. In January 2024, a comprehensive electronic search was carried out in esteemed databases including PubMed, Web of Science, and Scopus, employing carefully selected keywords such as ((bacteria) OR (virus) OR (fungi)) AND (aerosol) AND ((hospital) OR (healthcare) OR (dental office)) AND ((molecular) OR (PCR) OR (NGS) OR (RNA) OR (DNA) OR (metagenomic) OR (microarray)), following the PRISMA protocol. The review specifically targets healthcare environments with elevated concentrations of pathogenic bacteria. A total of 487 articles were initially identified, but only 13 met the inclusion criteria and were included in the review. The study disclosed that the prevalent molecular methodology for appraising aerosol quality encompassed the utilization of the PCR method, incorporating either 16S rRNA (bacteria) or 18S rRNA (fungi) amplification techniques. Notably, five diverse molecular techniques, specifically PFGE, DGGE, SBT, LAMP, and DNA hybridization methods, were implemented in five distinct studies. These molecular tests exhibited superior capabilities compared to traditional bacterial and fungal cultures, providing precise strain identification. Additionally, the molecular methods allowed the detection of gene sequences associated with antibiotic resistance. In conclusion, molecular testing offers significant advantages over classical microbiological culture, providing more comprehensive information.

Background The SARS-CoV-2 pandemic has raised awareness of the importance of air quality. This pilot study arose from the need to reduce the concentration of particulate matter in the dental office during orthodontic procedures. To evaluate the efficacy of using an air purifier during orthodontic care in the dental office to reduce the concentration of ambient particulate matter. Results Significant reductions in particle numbers were obtained for all particle sizes except the largest particles counted (10 μm) through use of the air filter. A marked association between higher humidity levels and higher particle counts was also observed. Conclusions Using an air purifier during dental care achieves a significant reduction in the concentration of ambient particles in the dental office. There is a correlation between higher relative humidity and higher particle concentration. The probability of obtaining a maximum particulate concentration level of 0.3 and 0.5 μm is 1000 times lower when using an air purifier.

“…Different materials produce different aerosols [30]. Lahdentausta et al found that air turbine handpieces produced the highest levels of <1-µm aerosols compared with other commonly used instruments [31]. Ishihama et al detected blood aerosols even at a distance of 1 m in droplets produced during third molar extractions using an air turbine [32].…”

Visualization of droplets and aerosols in simulated dental treatments to clarify the effectiveness of oral suction devices

Some infectious diseases, including COVID-19, are primarily transmitted via droplets and aerosols. Droplets are larger in particle size and settle to the ground faster due to gravity (3-6 feet) [3]. Aerosols are smaller in particle size and remain airborne for relatively long durations. The aerosol particle size has not been conclusively defined and reportedly ranges from less than 5 µm to 50 µm [4]. Larger particles can carry a higher quantity of viral load and are more likely to be deposited in the upper airways. In contrast, particles smaller than 10
