Infection control, sterilization, and public health requirements
This domain tests whether the candidate knows the practical infection-control rules a Kentucky dental office must follow and the public-health duties that accompany practice.
Core standard
Kentucky expects dental offices to follow current CDC infection-control guidance and OSHA’s bloodborne-pathogens rule (29 CFR 1910.1030). The operative idea is standard precautions: treat all blood and saliva as potentially infectious. That means hand hygiene, gloves, masks, eye protection, gowns when indicated, safe sharps handling, and respiratory hygiene.
Sterilization and monitoring
- Clean and dry instruments before packaging; use FDA-cleared sterilizers.
- Use chemical indicators on every load and biological spore testing at least weekly.
- Log every cycle and every biological test; retain records.
- Handpieces must be cleaned and heat-sterilized between patients; they are not “disinfected” with a wipe.
- Single-use items are not reused. Critical items must be sterile; semicritical items require at least high-level disinfection.
- Dental unit waterlines require flushing, maintenance, and monitoring under the office’s water-quality plan.
Public health
Report reportable communicable diseases to the local health department as Kentucky law requires. Maintain confidential handling of HIV and other sensitive test results. A clinician with a bloodborne infection must follow Board and CDC guidance regarding practice restrictions and expert review.
Worked example
A weekly spore test is positive. Reasoning: remove the sterilizer from service, reprocess instruments processed since the last negative test, notify affected areas, and document corrective action. Continuing to use the unit because chemical indicators looked normal is wrong: chemical indicators do not prove sterilization.
Traps that cost marks
- Confusing disinfection with sterilization for critical instruments.
- Skipping biological monitoring because the autoclave “seems fine.”
- Forgetting documentation; a missing log can be treated as a violation.
- Overlooking waterline maintenance and sharps-disposal rules.
