MDS PREP

The main purpose of intensifying screens in extraoral radiographic films is
1) To increase the contrast of film
2) To increase the exposure time
3) To decrease the speed of film
4) Decrease secondary radiation to patient

Radiology Answer: 4

Finish line which provides easy fit of the cast and burnishing of gold is
1) Chamfer
2) Knife edge
3) Shoulder
4) Bevel

Prosthodontics Answer: 2

Mean arterial pressure of the body is:
1. Systolic pressure + Diastolic pressure average
2. Systolic pressure / 2
3. Diastolic pressure/2
4. Diastolic pressure + 1/3 (systolic-diastolic) pressure

Physiology Answer: 4

In periapical lesions of average size, time needed for osteogenesis is�
�1. 1-2 months
�2. 2-6 months
�3. 6-12 months
�4. 2 weeks

Endodontics Answer: 3

Osteogenesis in periapical lesions of average size generally requires a
significant amount of time, typically falling within the range of 6-12 months.
This period allows for the complete healing of bone tissue around the root apex.

Amalgam which exhibits least creep and marginal breakdown is
1) High copper dispersion phase
2) High copper spherical
3) Conventional lathe cut
4) Conventional admixed

Conservative Dentistry Answer: 2

Most common malignancy in AIDS
1. Kaposi sarcoma
2. B cell lymphoma
3. Leukaemias
4. Burkitt lymphoma

Oral Pathology Answer: 1

Following are true for K-type file root canal instrument except
1) It is used for machining of dentin
2) The number of flutes on the blade is more in file than reamer
3) The file are fabricated from square or triangular crossection wire
4) Have more flexibility

Endodontics Answer: 1

Congenital occlusion or absence of one or more major salivary gland ducts is known as
1. Atresia
2. Aberrancy
3. Aplasia or agenesis
4. None of the above
