DENA 1050 – Infection Control & BBP Standard Review Sheet

In addition to immunization, what are the other important components that are an essential part of a successful infection control plan?

education & training, post‑exposure management, identifying medical conditions/work restrictions, record maintenance, data management, confidentiality

What are the five pathways for cross‑contamination and which is the most difficult to control?

patient→dental team, dental team→patient, patient→patient, dental office→community, community→patient; most difficult = patient→dental team

What are two infection control measures that can prevent patient‑to‑patient transmission?,

instrument sterilization, surface barriers

What are the three factors for infectious disease to develop?

virulence, dose, resistance

What are some procedures that minimize spraying or spattering of oral fluids?,

rubber dam, high‑volume evacuation, pre‑procedural mouth rinse

What is OSHA and what is their purpose?,

a regulatory agency that protects workers and enforces the Bloodborne Pathogens Standard

What consists of microorganisms that are always on the skin and can never be removed totally?

resident flora

What are housekeeping surfaces and with what and when should they be cleaned?,

floors/walls/sinks; cleaned with detergent or EPA disinfectant after procedures, when contaminated, and end of shift

What is bioburden

bioburden = organic debris;

What are three ways that dental office to community transmission can occur?,

contaminated impressions, improper waste disposal, microbes carried on clothing/hands

How long must employee medical records be kept by the employer?

30 years

What is the Bloodborne Pathogens Standard based on?

CDC guidelines

How does the BBP define an occupational exposure?

skin/eye/mucous membrane contact or percutaneous injury with blood or OPIM

What is the difference between regulatory agencies and organizations that make recommendations?,

regulatory enforce laws; recommendation groups advise only

What does PPE stand for?

personal protective equipment

When must utility gloves be worn?

when cleaning/disinfecting and handling contaminated instruments

Describe the difference between Engineering and Work Practice Controls and give an example of each:,

engineering = remove/isolate hazard (sharps container); work practice = change how task is done (one‑handed scoop)

What are some examples of sharps and how are they to be disposed?

needles, scalpel blades, ortho wires; disposed in puncture‑resistant sharps container

What is an important area of infection control not covered under the OSHA BBP and why?

instrument sterilization; OSHA protects workers, not patients

If you are wearing a face shield, is it necessary to also wear a mask?,

yes

What does the BBP require the employer to have before an exposure accident occurs?

a written exposure control plan

What follow‑up measures must be offered to an exposed worker without charge?,

counseling, HIV test series, HBIG if needed, tetanus booster, OSHA documentation

How long does the employer have to offer the HB vaccination?

within 10 days of employment

If the employee declines the vaccination but later decides to get it, does the employer still have to offer it at no charge?

yes

What is the order for the donning and removing PPE?, donning:

gown→mask→eyewear→gloves; removing: gloves→eyewear→mask→gown

What are overgloves used for?

to prevent contamination when touching clean items during treatment

List the four classifications of waste and give examples for each of them:,

1. – general: paper towels
   – contaminated: barriers, patient napkins
   – hazardous: toxic/flammable/corrosive chemicals
   – infectious/regulated: blood‑soaked materials, pathologic waste, sharps

what is bioflim

biofilm = microbial community on surfaces
