Deck 9: Clinical Considerations

Question 1

Which of the following contribute to dental caries and periodontal disease (Select all that apply. )?

A) Rough pits and grooves
B) The consistent presence of bacterial plaque on teeth
C) Inferior restorative dentistry
D) Intact enamel surfaces
E) Neglecting to replace missing teeth

Answer 1

A,B,C,E
Dental caries and periodontal disease are primarily caused by retention of bacterial plaque.Retentive factors include rough surfaces and projections,whether created by inferior restorative dentistry or naturally occurring pits,fissures,ridges,etc.Incomplete removal of calculus,stain,and biofilm during professional treatment are included in this list of causative factors.Note that selection "d" is not a correct answer because enamel provides a strong,resistant barrier.

Question 2

After placing a restoration,the dentist and auxiliary should check a patient's bite by having the patient chew a thin piece of sugarless gum because checking the bite ensures that no part of the restoration is hitting prematurely.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Answer 2

D
Articulating paper is the material of choice for checking the patient's occlusion after placement of a restoration.Articulating paper literally "articulates" occlusal patterns,which enable the dental professional to ensure that no part of the restoration is hitting prematurely.This critical step should not be skipped as premature contact results in occlusal trauma and leads to eventual fracture of the restoration and even the tooth itself.

Question 3

In protrusive occlusion,only the anterior teeth occlude.

Answer 3

True
As the mandible initiates protrusive movement,the distal area of the maxillary first molar hits the mesial area of the mandibular second molar.Once in protrusive occlusion,the posterior teeth should disengage;only the anterior teeth should occlude.

Question 4

If a mandibular first molar is lost,the mandibular second molar will

A) develop decay
B) supra-erupt
C) drift mesially
D) drift distally
E) None of the above

Question 5

Tooth migration can begin with 24 hours of an extraction.Tooth migration,otherwise known as mesial drift,of teeth is a natural phenomenon.

A) Both statements are true.
B) The first statement is true,the second statement is false.
C) The first statement is false,the second statement is true.
D) Both statements are false.

Question 6

Which of the following accurately describe preventive clinical considerations of existing dental conditions (Select all that apply. )?

A) Polishing restorations
B) Root planing
C) Using amalgam to fill a tooth
D) Removing plaque and calculus

Question 7

Which is the most common initial response to gingival recession?

A) Gingival inflammation
B) Plaque formation
C) Tooth sensitivity
D) Stain formation

Question 8

The walls of the pulp chamber are formed by dentin and enamel.

Question 9

Pulpal tissue cannot expand because the pulp is encased in hard dentinal tissue that makes expansion virtually impossible.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 10

A temporary crown can prevent mesial drift.

Question 11

Dentinal surfaces are rarely exposed during root planing because the envelope of cementum covering the root is quite thick.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 12

Occlusal trauma results in mobility of the affected teeth as well as migration and tipping of affected teeth.Although migrated teeth cause restorative dental problems,damage to the periodontium rarely occurs.

A) Both statements are true.
B) The first statement is true;the second statement is false.
C) The first statement is false;the second statement is true.
D) Both statements are false.

Question 13

An ideal situation is to have all teeth occlude equally on closure of the jaw because this pattern allows dissipation of occlusal forces over all of teeth.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 14

Pain can occur around a nonvital tooth because the nerve cells in the pulp frequently regenerate.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 15

When restoring the anatomy of a decayed tooth each of the following should be recreated EXCEPT one.Which one is the EXCEPTION?

A) Buccal and lingual contour
B) Deep occlusal pits and grooves
C) Interproximal contact area
D) Occlusal contact point

Question 16

Sealants are most effective in preventing decay in

A) interproximal areas
B) uneven enamel
C) buccal and lingual grooves
D) occlusal pits

Question 17

To some degree,prevention of periodontal disease is attributable to the smoothness of cementum because bacteria that initiate gingival and periodontal diseases are prevented from accumulating on smooth surfaces.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.

Question 18

When a tooth has no antagonist in the opposing arch,the tooth can

A) over-erupt
B) develop periodontal disease
C) develop dental caries
D) develop occlusal trauma
E) All of the above

Question 19

Each of the following is a common result of occlusal trauma EXCEPT for one.Which one is the EXCEPTION?

A) Muscle pain
B) Tighter contact areas
C) Nerve trauma
D) Periodontal pocketing

Question 20

During pulpal inflammation,arterial walls collapse and the venous walls remain intact because arterial walls are thicker than the walls of veins.

A) Both the statement and the reason are correct and related.
B) Both the statement and the reason are correct but are NOT related.
C) The statement is correct,but the reason is NOT correct.
D) The statement is NOT correct,but the reason is correct.
E) NEITHER the statement NOR the reason is correct.
