Question

Disease transmission in a dental procedure may occur from...

1) A contaminated dental instrument
2) Direct contact with blood or bodily fluids
3) Respiratory droplets
4) Contaminated water source

Answer 1

Disease transmission in a dental procedure can occur from contaminated dental instruments, direct contact with blood or bodily fluids, respiratory droplets, and contaminated water sources.

Step-by-step explanation:

In a dental procedure, disease transmission can occur from four main sources:

1. A contaminated dental instrument: If a dental instrument is not properly sterilized or if it comes into contact with infected bodily fluids, it can serve as a source of disease transmission.
2. Direct contact with blood or bodily fluids: If a dental professional or patient comes into direct contact with infected blood or bodily fluids, such as through accidental needle sticks or exposure to saliva or lesions, disease transmission can occur.
3. Respiratory droplets: Airborne transmission can occur if respiratory droplets, containing pathogens, are inhaled by nearby individuals during coughing or sneezing. This can be a route for the spread of diseases like the flu or the common cold.
4. Contaminated water source: If the water used in dental procedures is contaminated, it can serve as a source of disease transmission. Proper water quality and maintenance of dental unit waterlines are essential to prevent such transmission.
