DENTAL RADIATION AND SAFETY EXAM STUDY
GUIDE WITH VERIFIED ANSWERS 2026
A dosimeter badge should be worn:
- answer-To measure the amount of radiation received for a given period of time
A foremen is
- answer-A natural opening in bone/structures
A general rule of thumb is to fix ——- as the developing time -
answer-Double the time
All dots must be either concave or convex in order to tell
- answer-Right/left
Clean running water is used after developing and fixing
- answer-Removes developer solutions, removed remaining fixing solution, stops
the process. (All the above)
I'm the paralleling technique, the central beam must be
- answer-Perpendicular to the tooth and perpendicular to the film packet
If a radiograph remains in the developer solution too long the film will be
- answer-Darker
If the beam is not directed to the center of the film, the result is:
- answer-Cone cutting
In the developing and fixer solutions, which if the following acts as a solvent?
- answer-Clean water
In the production of x-rays what % of energy is converted into useful radiation? -
answer-1%
Incorrect horizontal angulation results in
- answer-Overlapping
, Maxillary sinus are
- answer-Located along the roots of the maxillary bicuspid and molars
maxillary tuberosity is
- answer-Curved bony eminence at distal end of maxillary alveolar ridge
Movement by the patients head or the tube head results in
- answer-Blurred image
Periapical films
- answer-Show the entire tooth, shows the area surrounding the apex, come in
different sizes. (All of the above)
Placement of the film backward in the patients mouth results in
- answer-Herringbone pattern
Radiopaque objects are
- answer-More dense,do not allow the passage of radiation, appear light/white on
the radiograph,metal restorations. (All the above)
The anode is the ——- terminal
- answer-Positive
The body structure most sensitive to ionizing radiation is
- answer-Reproductive organs
The cathode is the ——- terminal
- answer-Negative
The central beam that comes from the X-ray tube head is ——- radiation -
answer-Primary
The dot on the film is placed towards what surface of the anterior and posterior
teeth when taking PA's
- answer-Incisal or occlusal surface
The effects of radiation are
- answer-Cumulative
