Questions and CORRECT Answers
bass - CORRECT ANSWER - most common method for toothbrushing?
Replaces traditional mechanical plaque control measures - CORRECT ANSWER - Oral
chemotherapeutics are used to control plaque and prevent dental and periodontal diseases. Which
of the following is theleast true regarding the typical use of oral chemotherapeutics?
Decrease the number of microorganisms available to the clinical environment. - CORRECT
ANSWER - According to available research, an over-the-counter (OTC) or prescription
therapeutic preprocedural rinse can reliably be counted on to do which of the following?
true - CORRECT ANSWER - The two dimensions of oral chemotherapeutics are the
active ingredient and the delivery system. The delivery system can be either locally or
systemically applied.
true - CORRECT ANSWER - Periodontal disease is a complex infectious disease that
requires the colonization of bacterial pathogens; thus the control of bacterial plaque biofilm is an
essential component of any long-term strategy to prevent and control these dental diseases
Xerostomia - CORRECT ANSWER - liquid dentifrice is preferable for a client who:
potassium nitrate - CORRECT ANSWER - client suffering from dental hypersensitivity
must use dentifrice containing:
discuss the choices - CORRECT ANSWER - The dental hygienist encourages the client to

benefits help prevent gingivitis.
true - CORRECT ANSWER - The benefit of daily interdental cleaning such as flossing is
the reduction or prevention of inflammation caused by the immune response to the toxins
produced by interdental plaque biofilm. Evidence from a comprehensive systematic review
indicated that flossing in addition to toothbrushing reduces gingivitis in comparison with
toothbrushing alone
true - CORRECT ANSWER - Flossing is effective in reducing incidence of interdental
caries. Flossing and toothbrushing remove more plaque biofilm interdentally than toothbrushing
alone.
true - CORRECT ANSWER - End-rounding of toothbrush bristles are uniformly beneficial
for client safety. Soft bristles are less traumatic to oral tissues and remove as much or more
plaque biofilm than harder bristles.
bass - CORRECT ANSWER - For which method of toothbrushing are filaments directed
apically, placed partly on the cervical portion of teeth and partly on adjacent gingiva, and short
back-and-forth vibratory strokes are employed?
