Study Notes
Infection Risks in Dentistry
- Dental patients and professionals face exposure to various bacterial, viral, and infectious agents.
- Infection risk depends on microorganism concentration, type of disinfectant, contact time, and organic matter presence, such as blood or tissue.
Disinfectant Categories
- Disinfectants are classified based on their spectrum of activity: high-level, intermediate-level, and low-level.
- High-Level Disinfectants (HLD): Used for semi-critical items, effective against resistant organisms.
- Intermediate-Level Disinfectants: Suitable for non-invasive procedures; may not penetrate intact mucous membranes and require cleaning before use.
- Low-Level Disinfectants: Relevant for non-critical items without exposure to blood and other infectious materials.
Non-Invasive and Intermediate-Level Disinfection
- Non-invasive procedures involve contact with intact mucous membranes without penetration.
- Intermediate-level disinfectants clean clinical contact surfaces that are not barrier-protected after each patient.
Cleaning and Disinfecting Practices
- Impressions and appliances must be rinsed under running water post-removal to eliminate saliva, blood, and debris.
- Intermediate-level disinfectants are recommended to clean surfaces unlikely to be contaminated with bacterial spores.
Sterilization Methods
- Chemical Sterilization: Used when contamination with resilient organisms is possible; involves specific procedures and chemicals.
- Plasma Gas Sterilizers: Function at a temperature of 134°C for at least 3 minutes, effective for sterilizing a variety of instruments.
- Can also be used for sterilizing liquids, emphasizing nontoxic methods that are usually inexpensive.
