Viral Hepatites in Dental Practice: Risks and Prevention

Abstract

Objective: To discuss the epidemiological aspects of viral hepatites in dental professionals, with emphasis of the forms of transmission and prevention. Method: Narrative review of the literature on risks and prevention of the hepatites types in dental practice. Results: Hepatites are a group of inflammatory liver diseases with several etiologies, among which the most common are those caused by the A-E hepatotropic viruses. Hepatites A and E have acute and self-limited clinical presentation. Hepatites B and C may become chronic and progress to cirrhoses. The signs and symptoms of hepatites are similar and their evolution to the chronic form is silent or oligosymptomatic, which makes the disease being diagnosed incidentally, frequently at an advance stage. The early diagnosis increases the chances of chances of cure. Health professionals are at higher risk of having hepatites, especially those causes by the B and C viruses. Conclusion: Dentists, in their daily practice, are more exposed to accidents with cutting and perforating instruments, being thus a group with high risk of contamination. It is possible that other agents causing different forms of hepatitis or other diseases are identified in the future. The adoption of the universal infection control measures is and will always be essential for controlling transmissible diseases in dental facilities.
