CLINICAL MEDICINE

Detailed explanation-1: -Critical instruments are items used to penetrate soft tissue or bone. They have the greatest risk of transmitting infection and should be sterilized with the use of heat. Examples of critical instruments include forceps, scalpels, bone chisels, scalers, and burs.

Detailed explanation-2: -Critical items, such as surgical instruments and periodontal scalers, are those that penetrate soft tissue or contacts bone, enters into or contacts the vascular or other normally sterile tissue. They have the greatest risk of transmitting infection and should always be sterilized using heat.

Detailed explanation-3: -Medical devices that have contact with sterile body tissues or fluids are considered critical items. These items should be sterile when used because any microbial contamination could result in disease transmission. Such items include surgical instruments, biopsy forceps, and implanted medical devices.

Detailed explanation-4: -Critical instruments are those that come in touch with bones and soft tissues. These include scalers and scalpels.

Detailed explanation-5: -Critical instruments penetrate soft tissue or bone (i.e. scalpels, scalers, and burs). Semi-critical instruments contact oral tissue without penetration (i.e. dental mouth mirrors and dental impression trays). Non-critical instruments contact intact skin.
