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.
