Infection Control, Sterilization, and Occupational Safety
This section covers infection control and occupational safety; the exam tests sterilization monitoring, exposure control, and OSHA/CDC compliance.
The infection-control baseline
Kentucky dental practice follows CDC infection-control guidance and OSHA's Bloodborne Pathogens Standard. The office must have a written exposure control plan, offer hepatitis B vaccination, provide PPE, train staff, and maintain sharp-safety and hand-hygiene protocols. Standard precautions apply to every patient; you cannot rely on a patient's reported history.
Sterilization and monitoring
Instruments must be cleaned, packaged, and sterilized by a validated method, usually a steam autoclave, with biological spore testing at the required interval. Maintain a log of cycles, temperature/pressure, and spore results. If a spore test is positive, remove the sterilizer from service, reprocess affected loads, notify the dentist, and document corrective action. Use chemical indicators and proper storage.
Environmental and occupational safety
Disinfect clinical surfaces, manage regulated waste, and follow needlestick/exposure protocols: wash, report, seek evaluation, and document. OSHA requires confidentiality of health records and annual training. Eyewash stations, SDS access, and proper ventilation for nitrous oxide are part of the same safety system.
Worked example
A weekly spore test is positive. The correct response is not to repeat the test and keep using the autoclave. Take it out of service, determine which loads are affected, reprocess or discard, service the unit, and document the event and notification to the dentist.
Traps
Calling an item 'sterile' after wiping it with disinfectant. Skipping spore testing because the office is small. Treating OSHA as optional. Failing to document an exposure or a positive spore test.
