MDS PREP

While preparing occlusal cavity for amalgam in mandibular first premolar, the bur
1. Is kept absolutely vertical
2. Is tilted slightly buccally
3. Is tilted slightly lingually
4. Can be kept in any direction

Conservative Dentistry Answer: 3

Matrix band is difficult to adapt on upper first premolar because of
1) Axial inclination
2) Concavity in the cervical thirds mesially
3) Concavity in the cervical thirds distally
4) Presence of buccal ridges

Conservative Dentistry Answer: 2

The chief advantage of the composites compared to the silicates
1) Practically insoluble in oral fluids
2) Colour matching with the tooth structure is excellent
3) High modulus of resiliency
4) None of the above

Conservative Dentistry Answer: 1

Diagnosis of caries can be made clinically sometimes but accurate diagnosis cannot be made without radiographs
1) Only the first statement is correct
2) Both the statements are correct
3) Both the statement are wrong
4) Only the second statement is correct

Conservative Dentistry Answer: 2

The matrix retainer wherein anatomy adaptation is possible without wedges is
1) Tofflemire
2) Steele"s siqveland
3) Ivory no. 1
4) Ivory no. 8

Conservative Dentistry Answer: 2

The following factor determines the horizontal displacement of the proximal portion of class II inlay
1) Parallelism of the opposite buccal and lingual walls
2) Relationship between proximal box, isthumus and occlusal dovetail
3) Bevelling of the cavosurface, margins
4) Strength of the luting agent used for cementing

Conservative Dentistry Answer: 2

The axiopulpal depth of the proximal box in class II cavity is
1) 0.2 to 0.8 mm
2) 0.5 to 1 mm
3) 1 to 2 mm
4) 2 to 3 mm

Conservative Dentistry Answer: 1

In dental burs, the angle formed between the back of the blade and the tooth surface is called as
1) Clearance angle
2) Rake angle
3) Cavosurface angle
4) Point angle
