AHMED, R  y  AHMED, S. The Dynamics of Bioaerosol Contamination in Dental Clinics: Patterns, Risks, and Preventive Measures - A Review Article. S. Afr. dent. j. [online]. 2025, vol.80, n.2, pp.88-93. ISSN 0375-1562.  https://doi.org/10.17159/sadj.v80i02.19934.

Dental procedures, particularly those involving aerosol-generating techniques (AGPs), pose significant challenges in infection control due to the potential spread of bioaerosols. These aerosols, consisting of particles of varying sizes, can contain pathogenic microorganisms and settle on surfaces within the dental clinic, posing a risk of cross-contamination and infection. OBJECTIVE: This review aims to examine the extent and implications of bioaerosol contamination in dental clinics, focusing on the factors influencing aerosol dispersion, surface contamination patterns, and strategies for mitigating risks. METHODS: A comprehensive review of recent studies was conducted, analysing the spatial distribution of bioaerosols, particle size and settling times, contamination of environmental surfaces, and the effectiveness of various infection control measures. RESULTS: Bioaerosols generated during dental procedures can settle on surfaces after a certain period. The dispersion and settling of aerosols are influenced by particle size, type of dental procedure, and environmental factors such as ventilation. CONCLUSION: Proper management of bioaerosol transmission in dental settings is crucial for preventing nosocomial infections. Continued research and improved infection control measures are essential to ensure a safe environment for both patients and dental professionals.
