Exam 9: Clinical Considerations

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

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

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

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.

In protrusive occlusion,only the anterior teeth occlude.

Sealants are most effective in preventing decay in

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

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

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

MATCHING Evaluation of existing conditions requires that the dental professional understand preventive and restorative clinical considerations.Match the dental condition with the appropriate description. -Pulpal walls

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.

MATCHING Evaluation of existing conditions requires that the dental professional understand preventive and restorative clinical considerations.Match the dental condition with the appropriate description. -Apical foramen

Which is the most common initial response to gingival recession?

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

A temporary crown can prevent mesial drift.

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.

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?

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

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.
