Oral radiology quiz 3 Questions Fully Solved Latest Update 2025
General radiation (Bremsstrahlung or Braking radiation) - Answers High-speed electrons stop when they
hit the Tungsten Target (70% of x-rays formed this way)
Characteristic radiation - Answers Occurs when a high-speed electron dislodges an inner electron,
ionizing the atom
Two classifications of ionizing radiation - Answers Particulate and electromagnetic
Particulate radiation - Answers Tiny particles that travel in straight lines at high speeds
Electromagnetic radiation - Answers Propagation of wavelike energy (without mass)
atom components - Answers atoms consists of a nucleus- comprised of protons and neurons and
orbiting electons.
anode - Answers Positively charged electrode
cathode - Answers Negatively charged electrode
ion - Answers A charged atom
ionization - Answers occurs when there is a loss of an electron- x-ray photons can potentially cause this
in the patient. results in a positive ion (the unbalanced atom) and a negative ion( the free electron)
primary beam - Answers The most penetrating beam produced at the target of the anode
velocity - Answers speed of wave
wavelength - Answers measure from crest to crest
X-radiation - Answers a high-energy radiation produced by the collision of a beam of electrons with a
metal target in an x-ray tube
Molar view landmarks - Answers Maxillary sinus, boarders (hard palate, floor of the max sinus), coronoid
process, zygomatic process, hamular process
Premolar view landmarks - Answers Maxillary sinus, nasal sinus, boarders (flood of the maxillary sinus),
zygomatic process
Canine view landmarks - Answers Maxillary sinus, nasal sinus, inverted Y
Central/lateral view landmarks - Answers Incisive foramen, median palatine suture, nasal cavity (fossa),
anterior nasal spine, nose, septum
Maxillary sinus - Answers Radiolucent
