• Susceptible host

• Portal of entry

In a dental office, which mode of transmission occurs when a pathogen is spread through the air?

• Direct transmission

• Indirect transmission

• Airborne transmission

• Parenteral transmission

Identify the mode of transmission that involves the transfer of pathogens through a needle stick injury.

• Direct transmission

• Indirect transmission

• Airborne transmission

• Parenteral transmission

Which of the following is a method to prevent cross-contamination from the dental team to the patient?

• Using disposable gloves

• Sharing dental instruments

• Reusing masks

• Not washing hands

What is the role of maintaining aseptic conditions in a dental office?

• To increase the number of microorganisms

• To prevent disease transmission

• To make the environment more comfortable

Which component of the chain of infection is directly affected by the immune status of an individual?

• Virulence/infectious agent

• Number of microorganisms

• Susceptible host

• Portal of entry

What is the primary purpose of identifying the portal of entry in the chain of infection?

Which mode of transmission involves the transfer of pathogens from one patient to another through contaminated instruments?

• Direct transmission

• Indirect transmission

• Airborne transmission

• Bloodborne transmission

How can a dental office prevent cross-contamination from the community to the dental office?

• By sterilizing dental instruments

• By using personal protective equipment

• By implementing proper waste disposal

• By increasing patient appointments

Which of the following is a bloodborne mode of transmission in a dental office?
