Which instruments in a dental context would be considered non-critical?

• A. Those that contact hard surfaces only
• B. Those that penetrate the skin
• C. Those that should be sterilized after every use
• D. Those that come in contact with saliva

Answer: (A)

Non-critical instruments in a dental context are defined as tools that do not directly penetrate mucous membranes or contact blood. They typically come into contact only with intact skin or hard surfaces that do not harbor pathogens at the same level as mucosa or open wounds. This is why instruments that only contact hard surfaces are classified as non-critical. For instance, items such as dental chairs, light handles, or dental instruments used for patient satisfaction without penetrating the skin are considered non-critical. The risk of infection with these instruments is lower, and they typically require less stringent infection control measures, such as routine cleaning and disinfection, rather than sterilization. In contrast, instruments that penetrate the skin, are used directly on blood, or come into contact with fluids such as saliva do necessitate more rigorous methods of sterilization or disinfection due to increased risk of infection transfer. Understanding the classification of instruments based on their contact with different surfaces is key for implementing appropriate infection control and enhancing patient safety in a dental practice.
