01-Direction of mesial and distal walls in a class V amalgam cavity is determined by:

Direction of enamel rods

Caries extent

Gingivo-axial and occlusal-axial

Retention only

Correct! Wrong!

02-For the preparation of the rest seat the marginal ridge of a molar tooth is reduced by 2mm to achieve the correct depth of the rest seat. The marginal ridge is then rounded in order to:

Reduction the chances of fracture of the metal rest

Decrease food impaction

For the better distribution of the vertical load

Better clasp retention

Correct! Wrong!

03-The primary indication for precision attachment of RPD when the abutment teeth are well supported is:

When the patient is esthetically concerned

Abutment teeth require restoration

No posterior abutment teeth are present

When teeth are present on both the ends of the edentulous area

Correct! Wrong!

04-The design for a maxillary cast RPD framework with a double bar(anteriorly and posteriorly) type of major connector is indicated when:

Maximum palatal support is required

High vault type of palate

Acrylic plate for palate is to used

Where a single palatal strap connector would flex

Correct! Wrong!

05-The 1st step in the attention of the abutment teeth contour in the natural tooth preparation for the RPD is:

Preparation of the occlusal rest seat

Disking of the proximal surfaces, parallel to the path of insertion

Cutting is retentive undercut on the facial surface if needed

Decreasing the height of contour to the gingival one third on the abutment tooth

Correct! Wrong!

06-Precision attachments are contraindicated in:

All tooth supported cases

Crown with long coronal extent

Free end sadle case

Periodontal prosthesis case

Correct! Wrong!

07-A tooth which has not been in function and is now being used as an abutment may become symptomatic: the most likely results from:

Overstress

Pulpal reaction

Localized osteoclastic activity

Reaction within periodontal ligament

Correct! Wrong!

08-A patient comes with all the lower premolars & 1st molars removed, should the 2nd molars be removed? why?

Yes ,it will help in taking support from the ridge

No, 2nd molars will help in determining the vertical dimension

No, because for designing RPD sound posterior tooth with good bony support should not extracted

Yes, it will help in extending the denture to retromolar pad to have good retention

Correct! Wrong!

09-A complete clasp assembly consists of a:

Retentive arm and a reciprocal arm

Circumferential arm and bar type arm

Proximal plate and a retentive arm

Retentive arm, an occlusal rest and a reciprocating elements

Correct! Wrong!

10-The most effective means of limiting applied loads to abutment teeth in a distal extension partial denture is by:

Using a stress breaker

Using acrylic replacement teeth

Splinting abutments to adjacent teeth

Maintaining a stable base-tissue relationship

Correct! Wrong!
