RHS, Top Exam Questions and answers.
100% Accurate. Graded A+
developer - ✔✔-first chemical solution used to process radiographs
enamel - ✔✔-covers outside of crown of tooth
enamel - ✔✔-hardest living tissue in the human body
fixer - ✔✔-second chemical solution used in processing radiographs
identification dot - ✔✔-a raised dot on x-ray film to facilitate in the mounting process
latent image - ✔✔-image formed from crystal halide that is exposed to radiation; the image does not
form until it has been exposed to chemicals for a specified period of time
maxillary sinus - ✔✔-large cavity above the roots of maxillary molars
radiolucent - ✔✔-black region on x-ray indicating where radiation passed through the tissue
radiopaque - ✔✔-white/light region on the x-ray indicating where radiation was blocked by a tissue or
substance
replenish - ✔✔-to fill or refill with solutions
sinus - ✔✔-air-filled cavity in the skull in and around the nasal region
, supernumerary teeth - ✔✔-extra teeth typically dwarfed in size
periapical radiograph - ✔✔-capture the crown of the tooth, entire root, and surrounding structures
bitewing radiograph - ✔✔-captures first 1/3 of the tooth and does not include root or apex
occlusal radiograph - ✔✔-placed along the occlusal plane; shows surrounding maxillary or mandibular
bone structures, occlusal surfaces, and crowns of the teeth
panoramic radiograph - ✔✔-utilizes a special panoramic unit which rotates around patient's head;
captures entire maxilla, mandible, and surrounding structures on one film; patient stays stationary while
unit moves around patient's head
cephalometric radiograph - ✔✔-lateral and posteroanterior extraoral head films; typically used for
orthodontics or surgical cases
extraoral radiographs - ✔✔-used on disability patients; for patients who cannot open their mouths
usually
topical spray - ✔✔-benefits patients with high gag reflex
smaller film or sensor - ✔✔-benefits patients with shallower palates or floor of mouth
film-holding devices - ✔✔-(examples: rinn or snap-a-ray) align the x-ray beam with the film in the
patients mouth; stabilizes film in the mouth; reduces the need to re-expose patient
cotton rolls - ✔✔-stabilizes film holders when the patient has missing teeth
bitewing tabs - ✔✔-secures films so areas of interest in both maxillary and mandibular arch are
represented evenly
