Exam 9: Clinical Considerations

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

A temporary crown can prevent mesial drift.

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

Adjusting occlusion to discourage premature contact is considered a preventive therapeutic procedure.

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

Sealants are most effective in preventing decay in

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.

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

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

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

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

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

Which is the most common initial response to gingival recession?

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 the teeth.

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.

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.

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

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

In protrusive occlusion, only the anterior teeth occlude.
