1. In the text the acronym DHCP is used - what does it reference? - ANSWER
✓ refers to all paid and unpaid personnel in the dental health-care setting
who might be occupationally exposed to infectious materials
ie dentist, dental hygienest, dental assistant, front desk
2. Why do we use barriers? - ANSWER ✓ Barrier protection of surfaces and
equipment can prevent contamination of clinical contact surfaces, but is
particularly effective for those that are difficult to clean.
3. How do you manage barriers between patients? - ANSWER ✓ Because such
coverings can become contaminated, they should be removed and discarded
between patients, while DHCP are still gloved. After removing the barrier,
examine the surface to make sure it did not become soiled inadvertently. The
surface needs to be cleaned and disinfected only if contamination is evident.
Otherwise, after removing gloves and performing hand hygiene, DHCP
should place clean barriers on these surfaces before the next patient.
4. Why are you to wear a mask and nitrile gloves when disinfecting your
operatory? - ANSWER ✓ Because of the risks associated with exposure to
chemical disinfectants and contaminated sur- faces, DHCP who perform
environmental cleaning and disinfection should wear gloves and other PPE
to prevent occupational exposure to infectious agents and hazardous
chemicals.
5. Do you need to clean the wall in your operatory? Do you need to clean the
cabinet surfaces (vertical surfaces)? - ANSWER ✓ Unless contamination is
reasonably anticipated or apparent, cleaning or disinfecting walls, window
drapes, and other vertical surfaces is unnecessary.
, 6. What is regulated waste and have you experienced it in Clinic I? - ANSWER
✓ Examples of regulated waste found in dental-practice settings are solid
waste soaked or saturated with blood or saliva (e.g., gauze saturated with
blood after surgery), extracted teeth, surgically removed hard and soft
tissues, and contaminated sharp items (e.g., needles, scalpel blades, and
wires) and No
7. Why is there a concern over biofilm in the dental unit water lines? -
ANSWER ✓ These microorganisms colonize and replicate on the interior
surfaces of the waterline tubing and form a biofilm, which serves as a
reservoir that can amplify the number of free-floating (i.e., planktonic)
microorganisms in water used for dental treatment. These exhibit limited
patho- genic potential for immunocompetent persons.
8. Why should you run a dental handpiece that uses water 20-30 seconds after
the dental procedure has been completed? - ANSWER ✓ This procedure is
intended to help physically flush out patient material that might have entered
the turbine and air and waterlines.
9. Is it acceptable to disinfect your prophy angle handpiece (instead of placing
it through a sterilization cycle)? - ANSWER ✓ For processing any dental
device that can be removed from the dental unit air or waterlines, neither
surface disinfection nor immersion in chemical germicides is an acceptable
method.
10.How should you manage the handpiece coupling that remains in your
operatory? - ANSWER ✓ Such components (e.g., handles or dental unit
attachments of saliva ejectors, high-speed air evacuators, and air/water
syringes) should be covered with impervious barriers that are changed after
each use.
11.Why should you not let your patient close his/her mouth around the saliva
ejector "like a straw"? - ANSWER ✓ Studies have reported that backflow in
low-volume suc- tion lines can occur and microorganisms be present in the
lines retracted into the patient's mouth when a seal around the saliva ejector
is created.
12.What are the infection control procedures during obtaining and exposing
radiographs/digital plates? - ANSWER ✓ Gloves should be worn when
