Plaque Control and Dental Caries Flashcards
What are the sites where caries most commonly occurs?
- fissures
- proximal surfaces
- facial and lingual surfaces
- margins of restorations
T/F. Most survey data shows that most dentist and medical doctors believe that toothbrushing reduces caries.
True.
Toothbrushing with ___ toothpaste does reduce caries rates.
fluoridated
T/F. Evidence in support of the benefits of the efficacy of brushing independent of the effects of fluroide toothpaste is strong.
False, Evidence in support of the benefits of the efficacy of brushing independent of the effects of fluroide toothpaste is LACKING.
Toothbrushing alone without the addition of ___ ___ does NOT appear to be effective in reducing caries.
fluoride dentifrice
T/F. Even supervised self-brushing [without a dentifrice], interproximal flossing and checking with disclosant produced no reduction in caries over 3 yrs.
True.
T/F. Ubiquitous use of fluoride toothpaste makes it difficult to distinguish effects of fluoride from those of mechanical cleaning.
True.
What are the main reasons for the lack of efficacy of brushing for caries reduction independent of the effects of fluoride toothpaste?
- toothbrushing may not achieve plaque removal because bristles do not reach the caries-prone sites: fissures and proximal surfaces
- it is usually not carried out sufficiently thoroughly
How frequent should one brush?
twice a day with fluoridated toothpaste
How often should plaque be removed to be sufficient to prevent gingivitis?
every other day
T/F. Some evidence suggests that fluoride after meals reduces acid production.
False, Some evidence suggests that fluoride BEFORE meals reduces acid production.
Brushing before ___ provides long-term fluoride benefits. Advise patients to brush before ___ and at one other time.
bed; bed
Does the amount of toothpaste matter? Are higher concentrations of fluoride more effective?
No
Yes
Volume of water and vigor of rinsing both affect caries experience. Advise patients to rinse ___.
minimally
What age should brushing begin?
earlier commencement to brushing (before the age of 1yr) seems to correlate with lower caries experience.
T/F. Filaments arranged at different heights and angles have been demonstrated to be significantly more effective in caries reduction.
False, Filaments arranged at different heights and angles have been demonstrated to be significantly more effective in PLAQUE REMOVAL and REDUCING GINGIVITIS. No data on caries reduction
T/F. Powered toothbrushes with a rotation oscillation action reduce plaque and gingivitis more than manual toothbrushing.
True.
T/F. In regards to oral hygiene, studies indicate that no particular method is superior.
True.
Patients rarely exceed ___ sec per oral hygiene session.
60
Interproximal flossing my trained assistant at school reduced incidence of ___ caries by ___% for children with low ___ exposure.
proximal; 40; fluoride
reported daily home flossing had NO effect in the same study. Another study said self-flossing by adolescents for 2yr had no effect
Effective oral hygiene measures are probably more important for the maintenance of ___ health than for the prevention of ___.
periodontal; decay
___-___ professional prophylaxis has no effect on caries.
semi-annual
T/F. Professional prophylaxis every month substantially prevented caries.
False, Professional prophylaxis every TWO WEEKS substantially prevented caries.
Professional mechanical plaque removal (PMPR) in adults, particularly in combination with ___ ___ instructions, may be more effective for prevention of periodontal diseases than no treatment.
oral hygiene
