1. With regard to tooth loss, which of the two following factors is more important when considering their consequences and effects:

1.  
   
   1. A missing tooth.
   2. The location and relationship of the resultant space.

 

1. In the shortened dental arch concept of dental rehabilitation:

1.  
   
   1. The number of occluding pairs should be a minimum of 14 pairs.
   2. The number of occluding pairs should be a minimum of 10 pairs.
   3. Can be applied regardless of the patient’s age.
   4. Will most likely lead to an unfavorable prognosis.

 

1. Briefly list four of the possible consequences that can occur following tooth loss.

1. In a prosthodontic epdemiologic study, is a FPD pontic or an implant supported crown considered a missing or present tooth?

1.  
   
   1. Missing tooth.
   2. Present tooth.
   3. Depends on the objective of the study.
   4. Either one, it does not matter.
2. When designing a project to study the prevalence of construction of RPDs, it is important to account for:

1. From the following two columns, draw an arrow to connect each of the points in Column A with the most appropriate point in Column B. 

 

A		B
A clinical study		Usually has a large sample size
A questionnaire study		Usually more easy to conduct
A clinical study		Moderate cost
A questionnaire study		Produces more reliable data

 

 

 

1. During the assessment of the pre-edentulous dentition for purposes of selecting abutment teeth, certain considerations have to be examined. List three of these considerations:
