Microorganisms and Infections Overview

Infection in a dental clinic refers to the invasion and multiplication of microorganisms in the oral cavity or surrounding tissues, leading to disease or inflammation.

Human flora refers to the microorganisms normally found in the body, while transient flora are temporary microorganisms acquired from the environment.

Transmission of infection in dental clinics can lead to the spread of diseases between patients and dental staff, compromising health and safety.
