Biosafety in Dentistry: A Comprehensive Approach to Workplace Accidents

Clinical dental practice presented a high risk of occupational accidents, especially sharps injuries, which exposed health care workers to contact with pathogens transmitted by contaminated blood and body fluids. These incidents, associated with sharps handling, frequently occurred due to factors such as inattention, stress and patient movement. Hollow needles were identified as the main cause of percutaneous injuries, accounting for 56% of cases. Globally, health care workers reported infection prevalence rates 3-5 times higher than the general population. Against this background, universal biosecurity measures were highlighted as key tools to reduce the risks of disease transmission. These included barrier techniques, proper handling of contaminated waste and accident response protocols, ranging from immediate wound cleaning to administration of post-exposure prophylaxis within 2 hours of the incident. Studies indicated that a high proportion of accidents went unreported and that more than half of the professionals were unaware of biosafety protocols. This picture highlighted the urgent need for continuing education and supervision in the clinical setting, especially for students, who faced greater challenges due to their inexperience and constant exposure. Compliance with biosafety standards was crucial to minimise risks and ensure a safe working environment.
