Chapters 30, 31: Introduction to Image Interpretation & Descriptive Terminology Flashcards
Principles and Description of Image Interpretation
List the three terms that can be used to describe a lesion on an image.
- appearance
- location
- size
Define the term: mandibular teeth
teeth located in the mandible or lower arch
Define the term: vertical bite-wing
the bite-wing receptor is placed in the mouth with the long portion of the receptor in a vertical direction
Define the term: alveolar bone
bone of the maxilla and mandible that supports and encases the roots of teeth (appears radiopaque)
Define the term: intraoral image
- an image the results when an image receptor is placed inside the mouth and exposed to x-rays
- used to examine teeth
Define the term: horizontal bite-wing
the bite-wing receptor is placed in the mouth with the long portion of the receptor in a horizontal direction
Define the term: pericoronal
around the crown of a tooth
List the documentation requirements for dental imaging.
- date of exposure
- number and type of images
- evaluation of diagnostic quality
- list of limiting factors, retakes, or additional images needed
- detailed description of teeth
- detailed description of the bone and supporting structures
- detailed description of artifact
- indication of any areas that require additional imaging or clinical evaluation/confirmation
Define the term: dental radiographer
any person who positions, exposes, and processes dental x-ray image receptors
Define the term: occlusal
the chewing surfaces of posterior teeth
Define the term: apical
towards the apex of a tooth
Define the term: ground glass appearance / orange-peel appearance
a term used to describe a radiopacity viewed on a dental image that resembles pulverized glass
Define the term: interproximal
between two adjacent surfaces
Define the term: posterior
towards the back
Define the term: radiopacity / radiodensity
an area on a dental image appearing radiopaque (light/white) due to resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the image receptor
Define the term: periapical
around the apex of a tooth
Define the term: multifocal confluent radiopacity
a term used to describe multiple radiopacities on a dental image that appear to overlap or flow together
Define the term: inter-radicular
between the roots of adjacent teeth
List the terms used to describe the appearance of a radiopaque lesion on an image.
- focal opacity
- target lesion
- multifocal confluent
- irregular/ill-defined opacity
- ground glass opacity
- mixed lucent-opaque lesion
- soft tissue opacity
Define the term: adjacent / proximal
objects next to/touching each other
Define the term: apex
the area of a tooth that allows for blood vessels and nerves to enter the tooth and maintain the vitality of the tooth
Define the term: digital imaging
a system of filmless imaging used to capture an image using a sensor, breaking it into electronic pieces, and presenting and storing the image using a computer
List the common terms used to describe the location of a lesion on an image.
- periapical
- inter-radicular
- edentulous zone
- pericoronal
- alveolar bone loss
Define the term: multilocular
a term used to describe a radiolucent lesion on a dental image that exhibits multiple compartments
Define the term: radiolucency
an area on a dental image appears radiolucent ((dark/black) due to readily allowing the passage of the x-ray beam so that more x-rays reach the image receptor
Define the term: maxillary teeth
teeth located in the maxilla or upper arch
Define the term: dentition
the character of a set of teeth, including their number, kind, and location/arrangement
Define the term: radiopaque
the portion of an image that is light or white, due to the structure resisting the passage of the x-ray beam and limiting the amount of x-rays that reach the receptor
Define the term: mixed lucent-opaque
a term used to describe a lesion viewed on a dental image that exhibits both radiolucent and radiopaque components
Define the term: non-diagnostic image
an image that is not diagnostically accurate due to technique errors and must be retaken
Define the term: diagnosis
identification of a disease by examination or analysis
