CH 41- Intraoral Imaging
Question | Answer |
---|---|
The alignment of central ray of x-ray beam in horizontal and vertical planes. | Angulation |
Term for the intraoral technique of exposing dental images by determining the angle of the long axis of the tooth and image receptor, dividing that angle in half to position the central ray. | Bisecting Technique |
Type of image used for interproximal examination. | Bitewing |
The x-ray at the center of beam. | Central Ray |
Term used to describe the area at the mesial or distal surfaces of a tooth that touches an adjacent tooth in the same arch. | Contact Area |
The coronal portion of the alveolar bone found between the teeth. | Crestal Bone |
The impairment of mental or physical functioning that usually occurs before adulthood and lasts indefinitely. | Developmental Disability |
Term used to refer to images with the proper structures and necessary density, contrast, definition and detail for diagnostic purposes; if not they must be retaken. | Diagnostic Quality |
Term used to describe between 2 adjacent surfaces. | Interproximal |
To cut across or through. | Intersecting |
Term for the imaginary line dividing the tooth longitudinally (vertically) into 2 equal halves. | Long Axis of the Tooth |
The imaging technique used to examine large areas of the upper or lower jaw. | Occlusal Technique |
Moving in the same plane, always separated by the same distance. | Parallel |
Term for the most common intraoral technique of exposing periapical and bitewing images. | Paralleling Technique |
Intersecting at or forming a right angle | Perpendicular |
Intraoral device used to position and hold the film, sensor, or phosphor storage plate. | Positioning Instrument |
Angle of 90 degrees formed by two lines perpendicular to each other. | Right Angle |
