Q

Effective at-home hygiene measures are more important for ________ health than for caries prevention. What are better preventative measures for caries?

A

periodontal

fluoride and sealants

17
Q

What time frame for professional prophylaxis showed a substantial reduction in caries?

A

every two weeks

semi-annual has no effect, monthly has no effect

18
Q

______ _______ _______ ______ paired with Oral Hygiene Instruction is more effective for prevention of perio disease than either alone.

A

Professional Mechanical Plaque Removal

19
Q

Are antibiotics appropriate for plaque control?

A

Antibiotics will reduce levels of bacteria but are not appropriate for long-term use (resistance will develop and beneficial species will also be killed off)

20
Q

Chemical rinses used for plaque control are not effective against ______ problems.

A

subgingival

  • do not enter sulcus
  • do not act against GCF pressure
21
Q

What kind of rinse or varnish is available in 0.12% upon prescription?

A

Chlorhexidine

22
Q

What are the side effects to chlorhexidine rinse?

A

staining, calculus, taste alterations, and tissue irritation

23
Q

Is chlorhexidine better in treatment of gingivitis or caries reduction?

A

gingivitis

24
Q

What is casein phosphopeptide (Recaldent, MI Paste)?

A

-Milk protein bound to amorphous calcium phosphate
-binds to plaque
-Supplies calcium and phosphate during acid attack
(not as effective as fluoride, but some benefits seen)

25
Q

______ _______ compounds such as Scope and Viadent have not been proven effective against caries but they may remove plaque.

A

Quaternary Ammonium

26
Q

Which chemical agent has marked concern for safety? Why is it still used?

A

Triclosan (found in Colgate Total). Combined with fluoride has more effect against root caries than fluoride alone

Q

True or False: Essential Oils are effective against gingivitis but completely ineffective against caries.

A

False: SOME evidence for protection from caries exists

28
Q

What kind of mouthrinses will releases oxygen on contact with tissues and may be protective against anaerobic bacteria?

A

oxygenating mouthrinse

29
Q

True or False: Pre-brushing rinses are effective at loosening plaque for removal.

A

FALSE: plaque does NOT rinse off

30
Q

What is sanguinarine?
