What must be included in a dental office's written Exposure Control Plan per OSHA?
Answer: Exposure determination, schedule/methods for standard precautions, and post-exposure evaluation procedures
The ECP must include exposure determination, methods of compliance, HBV vaccination program, post-exposure procedures, hazard communication, and annual review.
What is the difference between antisepsis and disinfection?
Answer: Antisepsis is for living tissue; disinfection is for inanimate objects
Antisepsis applies antimicrobial agents to living tissue; disinfection eliminates pathogens on inanimate objects and surfaces.
Which hepatitis virus poses the greatest occupational risk to dental workers based on needlestick transmissibility?
Answer: Hepatitis B (HBV)
HBV has the highest transmission risk at 6-30% per needlestick from an HBeAg-positive source, compared to 1.8% for HCV and 0.3% for HIV.
What are spatter and aerosols in dental procedures, and how do they differ?
Answer: Spatter is larger droplets (>50 μm) settling quickly; aerosols are smaller particles (<50 μm) remaining airborne for extended periods
The critical difference is particle size: spatter settles quickly as a contact hazard, while aerosols remain suspended and can be inhaled deep into the respiratory tract.
How can dental treatment water serve as a vehicle for disease transmission?
Answer: Contaminated waterlines can transmit opportunistic pathogens through oral contact and via aerosols
Biofilm-contaminated waterline water contacts open wounds and becomes aerosolized, serving as a vehicle for transmission to patients and dental personnel.
What is the significance of OSHA's requirement for annual Exposure Control Plan review?
Answer: It ensures the plan reflects current science, new safer devices, regulatory updates, and lessons from exposure incidents
Annual review incorporates new technology, updated guidelines, exposure incident lessons, and changes in procedures that may affect risk.
