Which of the following is an example of an OSHA required sharp with engineered injury protection?

Answer: A self-sheathing needle attached to a dental anesthetic syringe

A self-sheathing needle attached to a dental anesthetic syringe is an example of an OSHA required sharp with engineered injury protection. This type of needle has a built-in mechanism that automatically covers the sharp tip after use, reducing the risk of accidental needlestick injuries. The other options, such as a cardboard needle guard, a butterfly needle, and a needle cap holder, do not provide the same level of engineered injury protection as a self-sheathing needle.

Explanation:
The air/water syringe is primarily used during the coronal polishing procedure to remove the remaining paste. This is because after the polishing paste is applied to the teeth and the polishing procedure is completed, there may be residue or excess paste left on the tooth surfaces. The air/water syringe provides a combination of air and water that helps to effectively rinse and remove the remaining paste, leaving the teeth clean and polished.

Prior to sterilization, loose contaminated instruments are processed in an ultrasonic cleaner to _____________ : 

Answer: Remove debris and bioburden 
Explanation:
The correct answer is c. remove debris and bioburden. Prior to sterilization, loose contaminated instruments are processed in an ultrasonic cleaner to remove debris and bioburden. This is important because sterilization is most effective when the instruments are thoroughly cleaned before the process. The ultrasonic cleaner uses high-frequency sound waves to create tiny bubbles that implode, creating a scrubbing action that helps to dislodge and remove any debris or bioburden present on the instruments. This ensures that the instruments are properly prepared for sterilization and reduces the risk of contamination.

The purpose of dental sealants is ______________________ :

Answer: To prevent decay in the pits and fissures of teeth

By sealing these areas, dental sealants create a barrier that prevents bacteria and food particles from getting trapped and causing decay. This helps to protect the teeth and prevent cavities from forming in these vulnerable areas.

20.

What type of mechanical device is used to clean contaminated instruments prior to sterilization? 

Answer: Ultrasonic 
Explanation:
Ultrasonic devices are used to clean contaminated instruments prior to sterilization. These devices use high-frequency sound waves to create microscopic bubbles in a cleaning solution.
