Study Notes
Occupational Hazards in Dentistry
- Occupational Hazards Definition: Risks and dangers associated with the nature and working conditions of a particular job.
Common Hazards in Dentistry
- Infections: Including HIV and viral hepatitis.
- Percutaneous Exposure Incidents: Exposure to blood, body fluids, and oral and respiratory infections, often from needlesticks and sharps injuries.
- Dental Materials: Potential hazards from materials used in dental procedures.
- Radiation: Exposure to radiation from x-rays, which can damage living tissues. Dosimeters measure radiation absorbed.
- Noise: Increased risk of hearing loss due to high noise levels in the dental environment.
- Musculoskeletal Disorders: Stress and strain on muscles and joints due to repetitive movements and awkward postures.
- Psychological Problems: Stress and anxiety related to the demands of the job.
- Dermatitis: Skin irritation or allergies from exposure to chemicals and latex.
- Respiratory Disorders: Potential for lung problems due to exposure to bioaerosols and airborne contaminants.
- Eye Insults: Risk of eye injuries from splatter and projectiles.
Exposure to Bioaerosols
- Risk of Infection: Bioaerosols, including bacteria, viruses, fungi, and yeast, are present in the air during dental procedures.
- Aerosol Composition: Aerosols can contain body fluids, blood, dental materials, powder, latex particles, and dust from metals.
Exposure to Toxic Effects of Chemicals
- Chemical Usage: Chemicals used in laboratory procedures, patient treatment, cleaning, sterilization, and dental x-ray processing.
- Mercury in Amalgam: Mercury, used in amalgam fillings, poses potential health hazards.
Exposure to Nitrous Oxide
- Nitrous Oxide Usage: Nitrous oxide, a colorless, tasteless, and sweet-smelling agent, is used to relax apprehensive patients.
- Inhaled by Staff: Staff can inhale nitrous oxide, which can lead to side effects.
Allergies to Latex Products
- Allergic Reactions: Latex products, such as gloves, can cause allergic reactions in some individuals.
Muscle Strain and Injury
- Ergonomics Definition: Adaptation of the human body to the work environment to improve efficiency and well-being of employees.
Prevention
- Universal Precautions: Standard precautions to minimize exposure risks.
- Improved Ergonomics: Adjusting workspaces and practices to improve posture and reduce physical strain.
- Changing Gloves: Regularly changing gloves to prevent contamination and cross-infection.
- Careful Handling of Soiled Items: Proper handling and disposal of contaminated materials.
