INTRO TO DHYG FINAL EXAM QUESTIONS &
ANSWERS
Mineralized dental biofilm that is filled with crystals of various calcium phosphate
mineral salts between previously living organisms. - answer -dental calculus
Dental calculus is cover with a layer of ______ dental ____ contain gin viable, active
baceria - answer -non mineralized
Biofilm
The hard, tenacious masses can form on what surfaces? - answer -crowns of natural
teeth
Dental implants
Dentures
Other dental protheses
Comprehensive understanding of the characteristics, origin, development, and methods
of prevention of calculus is essential to patient examination, assessment, treatment, and
instruction. - answer -clinical care
For successful treatment and prevention, the patient needs to know the interrelationship
between biofilm, calculus, and oral health; the need for complete removal of calculus;
and the reasons for the meticulous manner in which scaling procedures must be carried
out. - answer -patient learning
Dental calculus is classified by its ______ on a tooth surface as related to the adjacent
free gingival margin, that is, supragingival and subgingival. - answer -location
Calculus on clinical crowns coronal to margins of gingiva - answer -supragingival
Calculus over crown, exposed root surface, & the margin of gingiva - also on complete
& partial dentures - answer -supragingival
Calculus along root to the bottom of a periodontal pocket - answer -subgingival
Lingual surfaces of mandibular anterior teeth
Facial surfaces of maxillary 1st and 2nd molars, opposite the open dins of the ducts of
the salivary glands - answer -most frequent sites for supra gingival calculus?
Supra marginal, extra gingival, coronal, & salivary are other names for ____ calculus -
answer -supra gingival calculus
Clinical crown apical to the margin of the gingiva and extending nearly to the clinical
attachment on the root surface, is what type of calculus? - answer -subgingival
