Descriptive terminology allows dental professionals to
Describe and discuss what is seen on all dental image intelligently and to communicate using common language.
Descriptive terminology
Describes the appearance location and size of lesions and should be documented for all lesions viewed on dental images
A written description of what is viewed indicates
A qualified dental professional interpreted the dental image
Use of dental terminology requires that the dental professional have a basic understanding of five general terms they are
Radiograph,dental image, X-ray, radiolucent, radioplaque
Radiograph
A two deminsional representation of a tree dimensional object
Radiograph refers to the
Actual film exposed
X-ray refers to the
Beam of energy , or radiation
The dental professional should refer to a radiograph as an
X-ray film
Preicoronal
The area around the crown of an impacted tooth
The appearance of a radiopaque lesion can be described using
Focal opacity, target lesion, multifocal confluent, irregular, ground glass, or mixed Lucent opaque
Radiopaque lesions occur not only in bone but also
Soft tissue
Target lesion
A well defined radiopaque are surrounded by uniform radiolucent halo
Soft tissue opacity
Appears as A well defined , radiopaque are located in soft tissue
Radiopaque lesions may appear in the same locations as radiolucent lesions such as
Periapicle, inter radicular , endentulous or pericoronal locations
The dental personal should interpret all dental images while
The patient is present to verify what is seen.
Metallic restorations ( amalgam, gold )
Absorb X-rays as a result very little if any radiation comes in contact with the receptor. Appear white or ( radiopaque )
Non metallic restorations ( porcelain ,composite, acrylic )
May very in appearance from ( radiolucent) dark or black, to slightly radiopaque ,depending on the density of the material.
Of the non metallic restorations
Porcelain is the most dense and least radiolucent , and acrylic is the least dense
Amalgam overhangs can be described as
Extensions of the crown portion in the interproximal region
A large radiopaque restoration with smooth borders is most likely
Gold
Post a core restorations can can be seen in teeth treated with
Endodontic therapy
Porcelain restorations appear
Slightly Radiopaque and resemble the radio density of Dentin
Metallic restorations appear
Totally radiopaque
All porcelain crowns appear
Slightly radiopaque with a thin radiopaque line outlining the prepared tooth. This line represents cement.
