Occupational Hazards in Dentistry Prof P Brijlal Occupational hazards definition A risk or danger as a consequence of the nature or working conditions of a particular job Common hazards in Dentistry Infections (including Human Immunodeficiency Virus and viral hepatitis) Percutaneous exposure incidents Dental materials Radiation Noise Musculoskeletal disorders Psychological problems Dermatitis Respiratory disorders Eye insults Classification EXPOSURE TO RADIATION Radiographs has the potential to damage living tissue. Dosimeter badge calculates the amount of radiation absorbed EXPOSURE TO INFECTIOUS DISEASES Usually occurs through a needle stick / sharps injury. Exposure to a variety of microorganisms via exposure to blood, body fluids, oral and respiratory infections. EXPOSURE TO BIOAEROSOLS (AIRBORNE CONTAMINATION) Bioaerosols – risk for infection A mist is created containing microbes such as bacteria, viruses, fungi and yeast. Dental aerosols may contain body fluids, blood, dental materials, powder, latex particles and dust from metals. EXPOSURE TO TOXIC EFFECTS OF CHEMICALS Chemicals are used in laboratory procedures, patient treatment, cleaning, sterilization and dental x-ray processing. Mercury used in amalgam fillings are an example of potential hazards. EXPOSURE TO NITROUS OXIDE Nitrous oxide and oxygen is a color-less, tasteless and sweet-smelling agent used to relax apprehensive patients. Can be inhaled by staff with potential side effects. ALLERGIES TO LATEX PRODUCTS Allergic reactions to the material  MUSCLE STRAIN AND INJURY Ergonomics definition Adaptation of human body to the work environment.
