MDS PREP

Which radiographic projection is most useful in examining stone of a submandibular duct
1) Cross-sectional occlusal
2) OPG
3) Lateral oblique
4) PA view of mandible

Radiology Answer: 1

Which of the following provides superior definition of soft tissues, bony details and physiologic information about the TMJ joint
1) MRI
2) Pantomograph
3) Arthrography
4) CT scan

Radiology Answer: 3

Fogging of X-ray film affects the contrast of an intraoral film because it
1) Produces phosphorous crystals on the film
2) Decreases film density resulting in a light radiograph
3) Produces white speckles on the firm
4) Increases film density resulting in an overall gray radiograph

Radiology Answer: 4

Choose the false statement among the four
1) X-rays are ionizing rays
2) X-rays can be focused
3) X-rays cannot be seen or touched
4) X-rays can cause mutation

Radiology Answer: 2

Mean exposure at skin from an intraoral periapical radiographs
1) 300 mR
2) 0.03 mR
3) 47 mR
4) Both A and B

Radiology Answer: 4

Density of film is inversly proportional to all of the following except
1) Collimation
2) Filteration
3) Target-film distance
4) Kilo volt

Radiology Answer: 4

The cells which are least susceptible to radiation are
1. Fibroblasts
2. Lymphocytes
3. Osteoblasts
4. Erythroblasts

Radiology Answer: 4

To obtain better information of cyst eroding the surface of cortex
1) Exposure time should be reduced
2) Exposure time should be increased
3) Voltage should be increased
4) Milliamperage increased
