AADC Certified Dental Consultant (CDC) — Questions and Answers
Question 1: A dental consultant reviewing infection control protocols notices staff are reprocessing heat-sensitive instruments using only high-level disinfection rather than sterilization. What is the correct standard?
- Heat-sensitive instruments may be used without reprocessing if single-use packaging is intact
- High-level disinfection is acceptable for semi-critical items
- Chemical vapor sterilization is the only acceptable method
- All instruments that penetrate soft tissue must be sterilized (Correct answer)
Correct answer: All instruments that penetrate soft tissue must be sterilized
Instruments that penetrate soft tissue or bone are classified as critical items and must be sterilized, not merely disinfected.
Question 2: A dental management consultant recommends a 'co-diagnosis' approach during hygiene appointments. This technique primarily improves:
- The accuracy of radiographic interpretation by using two clinicians
- Insurance pre-authorization approval rates
- Case acceptance by having the hygienist engage patients in understanding their own clinical findings before the dentist presents the treatment plan (Correct answer)
- Infection control compliance during the clinical examination
Correct answer: Case acceptance by having the hygienist engage patients in understanding their own clinical findings before the dentist presents the treatment plan
Co-diagnosis engages patients emotionally and educationally during the hygiene appointment so they arrive at the dentist's exam already understanding and invested in their treatment needs.
Question 3: What is the purpose of Coordination of Benefits (COB) rules in dental insurance?
- To determine which plan pays first when a patient has multiple dental coverages (Correct answer)
- To set maximum benefit amounts
