Overview of Infectious Diseases of Concern to Dental Practitioners: Blood-Borne and Related Pathogens

The occupational hazards faced by dental practitioners are multifaceted, with one of the most significant being exposure to infectious diseases, specifically blood-borne pathogens. These include hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and human immunodeficiency virus (HIV). Each pathogen presents unique challenges in terms of their transmission, pathogenicity, clinical manifestations, and management. HBV, HCV, and HDV primarily result in hepatic diseases that can range from acute infection to chronic liver disease and hepatocellular carcinoma. HIV, however, significantly impacts the immune system, potentially leading to acquired immunodeficiency syndrome (AIDS) if left untreated. Given their occupational exposure to these pathogens, dental practitioners must have a comprehensive understanding of their nature, and modes of transmission. While hepatitis A virus (HAV) and hepatitis E virus (HEV) are not considered to be blood-borne, these infections are included because they may have relevance to the dental practitioner. The emphasis throughout is on the essential role of dental practitioners in understanding, preventing, and managing the transmission of blood-borne and related pathogens.
