Dental Radiography :Questions and Answers 2025
________ in film emulsion absorb the x-radiation during xray exposure and store the energy from the radiation
- anssilver halide crystals
__________ transform xray energy into visible light, which in turn exposes the screen film - ansintensifying
screens
2 Types of localization - ansbuccal object rule
(Same=Lingual, Opposite=Buccal)
Right angle technique
3 conditions for infection control to occur - anssusceptible host, pathogen with suffiencient infectivity and
numbers to cause infection
5 basic rules of paralleling technique - ansfilm must cover prescribed area, film positioned parallel to long axis
of tooth, central ray directed perpendicular to film and long axis of tooth, central ray directed through contact
areas between teeth, and xray beam centered over film to ensure all areas of film are being exposed
5 steps in film processing - ansdevelopment, rinsing, fixation, washing, and drying
adhesive layer - anscovers both sides fo film base, serves to attach film enulsion to both sides of base
advantages of paralleling technique - ansproduces images with dimensional accuracy,simple and easy to learn
and use, easy to standardize, and can be accurately repeated
after processing - ansradiograph
anterior teeth film size - ans1
, Before processing - ansfilm
bisecting is also known as - ansthe short cone technique
bisecting technique used to expose - ansperiapical films
bite-wing (BW) - ansinterproximal surfaces of crowns of upper and lower and crestal bone, open contacts only-
no overlap, vertical bitewing used on anteriors
bite-wing includes - anscrowns of maxillary and mandibular teeth, interproximal areas, and areas of crestal
bone on the same film
Calcium Tungstate - ansintensifying screen crystal, gives off blue light and must pair with blue-sensitive film
cephalometric film - ansshows bones of face and skull and the soft tissue palate
chemical solution used in development process to reduce the exposed, energized silver halide crystals -
ansdeveloper
correct vertical angulation has the tooth... - ansthe same size as the film
dental radiographs should always be mounted when - ansimmediately after processing
developer solution 4 basic ingredients - ansdeveloping agent, perservative, accelerator, and restrainer
disease transmission may occur as a result of - ansdirect contact with pathogens in saliva, blood, respiratory
secretions, lesions...indiret contact with contaminated objects or instruments....direct contact with airborne
contaminants present in spatter or aerosols or oral and respiratory fluids
