  The Quiz:

For a score of at least 70% (seven out of ten) you will be issued one hour of CE credit through the Arizona Dental Association (AzDA). There is a $20.00 processing fee for AzDA members and $40 for Non-AzDA members for each test submitted. A portion of the proceeds will go to the Arizona Dental Foundation for its charitable dental events. All tests will be handled confidentially. AzDA is a Continuing Education Recognition Program (CERP) provider conducted under the auspices of the American Dental Association.
1 - Since 1986, all three CDC Dental Infection Control Guidelines has recommended that to reduce microorganisms in the dental unit water (DUW), you should:
    flush a bleach solution through the dental unit at the beginning and end of each clinic day.
    use sterile water or sterile saline as a coolant/irrigator when performing surgical procedures.
    flush only the handpieces for 20-30 seconds after completion of a procedure
    flush phenol solution through the dental unit at the end of the clinic week.
2 - Left untreated, dental unit water can:
   safely be used for all dental procedures.
   support microbial growth with colony counts in the hundreds of thousands to millions
   cause serious infections in dental patients
   b and c only.
3 - During normal testing of DUW, you:
   only count the number of colonies that have grown out on the incubated water sample.
   must identify every microorganism present.
   must air purge all the lines before taking a sample.
   only test for pathogens.
4 - According to the CDC, the current standard for DUW is the same as the EPA’s standard for drinking water which is:
   >200 CFU/mL
   >300 CFU/mL
   >400 CFU/mL
   >500 CFU/mL
5 - The following devices can be used for sterile water or saline irrigation during oral surgery except:
   a dental unit with an attached filter.
   a sterile irrigating syringe with single-use sterile saline or sterile water.
   single-use sterile disposable tubing.
   single-use sterile IV saline or water solution.
6 - Training dental healthcare personnel in the appropriate DUW maintenance protocols should include all except:
   a) following step-by-step directions from the product manufacturer.
   b) knowing that DUW quality is just a fringe issue and does not have to be taken seriously.
   c) knowing that untreated DUW can cause serious medical issues in patients exposed.
   d) understanding that they are important members of the dental team.
7 - Treating then monitoring your dental unit water:
   is a requirement of OSHA law.
   should be made with the guidance of your dental equipment manufacturer.
   is an awfully expensive procedure these days and not worth the effort.
   follows an extraordinarily complex protocol that only the dentist is allowed to do.
8 - When testing you should:
   treat and test until you attain the EPA standard then test quarterly.
   use third-party testing at least once a year.
   document and keep records.
   all of the above.
9 - M. abscessus:
   is a rapidly growing invasive nontuberculous mycobacterium
   has caused outbreaks in pediatric clinics from untreated DUW
   is a noninvasive nontuberculous mycobacterium
   a and b only
10 - Current CDC dental guidelines recommendations for safe dental care
   are outdated and not useful in their present form.
   are more user-friendly and include check lists.
   are hard to follow.
   are unattainable.
