Q. Rationale for infection control?

The answer lies in the fact that many infectious diseases may be transmitted during dental care. Source of potential infection that exists in dental office include hands, saliva, nasal secretion, blood, clothing & hair as well as dental instrument and equipment.

Infectious microbial agents can spread by direct contact, indirect contact via a contaminated surface or material, spattering of secretions and aerolisation. Hence goal of infection control is to reduce the dose of micro-organisms that may be shared between individuals and contaminated surfaces.
