#1
Which type of radiation is used in dental radiography?
X-rays
ExplanationX-rays are utilized in dental radiography for imaging the oral structures.
#2
What is the purpose of a dental radiograph?
All of the above
ExplanationDental radiographs serve multiple purposes, including diagnosing cavities, evaluating bone health, and assessing tooth development.
#3
What is the term for the white or light areas seen on a dental radiograph?
Radiopaque
ExplanationRadiopaque areas on a dental radiograph appear white or light due to their ability to block X-rays.
#4
What is the term for the dark areas seen on a dental radiograph?
Radiolucent
ExplanationRadiolucent areas on a dental radiograph appear dark due to their ability to allow X-rays to pass through.
#5
Which of the following factors affects the image sharpness in dental radiography?
All of the above
ExplanationVarious factors, including focal spot size, movement, and film resolution, collectively impact the sharpness of images in dental radiography.
#6
Which of the following is NOT a type of dental radiograph?
Transverse radiograph
ExplanationTransverse radiograph is not a recognized type of dental imaging technique.
#7
What is the purpose of a lead apron during dental radiography?
To protect the dental professional from radiation
ExplanationA lead apron is worn to shield dental professionals from potential radiation exposure during X-ray procedures.
#8
What is the function of a developer solution in film processing?
To remove unexposed silver halide crystals
ExplanationDeveloper solution is used to chemically process the film and remove unexposed silver halide crystals, revealing the latent image.
#9
Which type of dental radiograph provides a two-dimensional view of the entire dentition?
Panoramic radiograph
ExplanationPanoramic radiographs offer a comprehensive two-dimensional view of the entire dentition, aiding in diagnosis and treatment planning.
#10
What is the purpose of a fixer solution in film processing?
To fix the image onto the film
ExplanationFixer solution stabilizes and fixes the developed image onto the film, preventing further chemical reactions.
#11
Which of the following is NOT a step in film processing?
Exposing
ExplanationExposing is not a step in film processing; it involves capturing the image during X-ray exposure.
#12
In dental radiography, what does the term 'PID' stand for?
Position-Indicating Device
ExplanationPID stands for Position-Indicating Device, helping to position and direct the X-ray beam accurately.
#13
Which of the following factors affects the speed of film processing?
All of the above
ExplanationVarious factors, including temperature, agitation, and chemical concentrations, collectively affect the speed of film processing.
#14
What does 'SLOB' stand for in dental radiography?
Same Lingual Opposite Buccal
ExplanationSLOB, or Same Lingual Opposite Buccal, is a technique used to discern the location of objects in dental radiographs.
#15
Which of the following factors affects the contrast of a dental radiograph?
Kilovoltage
ExplanationThe kilovoltage setting influences the contrast in dental radiographs by controlling the penetration and energy of X-rays.
