Radiation

Automatic -  processor machine that automates all film-processing Steps


beam alignment device -  assists in the positioning of the position indicator device


Bitewing - image view that shows the crowns of both arches on one film


calcium tungstate - common type of phosphor


cassette - contains extraoral films during exposure


cephalometric film - shows the bony and soft tissue areas of the facial profile


charge-coupled device (CCD) -  solid-state image sensor used in intraoral digital imaging


digital image - electronic signals captured by sensors and displayed on computer monitors


digitize - scanning of traditional film-based radiographs into a digital image


duplicating film -  film designed for use in film duplicating Machines


emulsion (ee-MUL-shun) - coating on the x-ray film that contains energy-sensitive crystals


extraoral film - film designed for use in cassettes


film speed - sensitivity of the emulsion on the film to radiation intensifying screen part inside an extraoral cassette that converts x-ray energy into visible light, which in turn exposes screen film


intraoral film - film designed for placement in the patient’s mouth


label side - colored side of the film that faces the tongue


latent image - invisible image on the x-ray film after exposure but before processing


Occlusal - radiographic view that shows large areas of the maxilla or mandible


panoramic film - used in cassettes to provide a wide view of both the upper and lower jaws


periapical (per-ee-AP-i-kul) - radiographic view that shows the crown, root tip, and surrounding structures


phosphor storage plate (PSP) - reusable film-sized plates coated with phosphor as the image receptor


positioning instruments - intraoral devices used to position and hold the film, sensor, or PSP 

processing - series of steps that change exposed film into a radiograph; steps include developing, rinsing, fixing, washing, and drying


radiograph (RAY-dee-oe-graf) - image produced on photosensitive film by exposing the film to radiation and then processing it

teledentistry - process of using electronic transfer of images and other information for consultation and/or insurance purposes in dentistry 


tube side - solid white side of the film packet that faces the x-ray tube


artifact - blemish or unintended radiographic image that is not present in the actual structure


confidentiality - never revealing any personal information about the patient


Disclosure - process of informing the patient about a procedure, for example, the procedure for taking x-rays


image receptor - recording medium for an image—a digital sensor, a phosphorstorage plate (PSP), or conventional dental x-ray film


informed consent - permission granted by a patient after being informed about the risks, benefits, and alternatives of a procedure


liability - accountability or legal responsibility


malpractice - professional negligence


Negligence - failure to provide a proper or reasonable level of care


phosphor storage plates (PSPs) - reusable film-sized flexible plates coated with phosphor as the image receptor


positioning devices - intraoral devices used to position and hold the film, sensor, or PSP


quality assurance (QA) - plan to ensure that the dental office produces consistent, high-quality images with a minimum of exposure to patients and personnel


quality control -  tests specific tests used to ensure quality in dental x-ray equipment, supplies, and film processing


risk management - policies and procedures that will reduce the chance that a malpractice lawsuit will be brought against the dentist; key areas of risk management include patient-informed consent, patient records, confidentiality, liability issues, and patient education


standard of care - level of knowledge, skill, and care comparable with that of other dentists who are treating similar patients under similar conditions


stepwedge - device constructed of layered aluminum steps to demonstrate film densities and contrasts


view box - illuminated boxlike device used to view radiographs


angulation alignment of central ray of x-ray beam in horizontal and vertical planes


bisecting (bisection of the angle) - technique intraoral technique of exposing dental images

bitewing type of image used for interproximal examination


central ray - x-ray at center of beam


contact area area of the mesial or distal surfaces of a tooth that touches an adjacent tooth in the same arch


crestal bone - coronal portion of alveolar bone found between the teeth


developmental disability - impairment of mental or physical functioning that usually occurs before adulthood and lasts indefinitely


diagnostic quality - referring to images with the proper structures and necessary density, contrast, definition, and detail for diagnostic purposes


Interproximal - between two adjacent surfaces


intersecting - cutting across or through


long axis of the tooth - imaginary line dividing the tooth longitudinally (vertically) into two equal halves


occlusal technique - used to examine large areas of the upper or lower jaw


parallel - moving or lying in the same plane, always separated by the same distance


paralleling technique - intraoral technique of exposing periapical and bitewing images


perpendicular - intersecting at or forming a right angle


physical disability -  impairment in certain function(s) of the body,

such as vision, hearing, or mobility

  • radiographic technique - A method used to capture images of dental structures, ensuring optimal positioning to achieve accurate diagnostic results.

positioning instrument - intraoral device used to position and hold the film, sensor, or phosphor storage plate


right angle - angle of 90 degrees formed by two lines perpendicular to each other
