RADIOGRAPHIC APPEARANCE OF RESTORATIVE MATERIAL AND
FOREIGN BODIES IN TEETH, JAWS AND SOFT TISSUES

RESTORATIVE MATERIALS
AMALGAM • Completely radiopaque
OVERHANGING AMALGAM
METALLIC CROWN : Gold, semiprecious metal :
Radiopaque approximately same density as amalgam, totally opaque, usually follows contour of tooth and smooth borders
- Stainless steel crown : Less radiopaque, contour and shape usually
does not follow tooth anatomy since it is usually a temporary restoration
- Porcelain fused to metal crown : The metal portion appears as a totally
radiopaque center and the porcelain appears slightly radiopaque around the occlusal, incisal, and sometimes visible on cervical areas
Crown and bridge with metallic coping and porcelain facing
Jacket crown with metallic coping and porcelain facing
PORCELAIN CROWN Appears slightly radiopaque with a thin outline
of the tooth preparation due to the cement securing the restoration.
COMPOSITE RESTORATIVE MATERIALS Silicates, resins and some composites tend to be
radiolucent and simulate caries. Composites with fiberglass particles in them are radiopaque. Therefore composites vary from radiolucent to slightly radiopaque
Silikat restorations Composite restorations in cervikal of teeth
BASE MATERIAL Some base and pulp capping materials
contain Barium Sulfate or similar radiopaque materials.
Radiopaque appearance of base material behind radiolucency of composite restorations
CEMENT Zinc phosphate and zinc oxide and eugenol appear as
slightly radiopaque thin line.
RETENTION PIN Radiopaque cylindrical or screw-shaped projections at
the base of a restoration
ENDODONTIC FILLING Gutta percha appears radiopaque similar in
density of base materials, Silver points are very radiopaque, similar to
metallic materials, more radiopaque than gutta percha.
ENDODONTIC TREATMENT
File instrument in root canal Gutta percha (master cone) in root canal
GUTTA PERCHA WERE USED TO FILL ROOT CANALSIN ROOT CANAL THERAPY AND TOOTH WASRESTORATED WITH AMALGAM
Lateral perforation of file in root canal therapy.
11 is inadequately root filling and has a lateral perforation of the root. Note the unusual design of the post crown.
Radiograph of 41 shows excess of cement extruded into periapical tissues, where there is a small radiolucency. The increased radiopacity on the crown is due to smearing of temporative dressing material.
Inadequately root filling with acrilic jacket crown restoration
Apicectomies and retrogade amalgam root fillings. Both teeth have porcelain-faced gold crown and contain gutta percha root fillings
POST AND CORE Radiopaque with extension of the post into the
pulp canal
IMPLANT Implants appear radiopaque within the
alveolar bone
REMOVABLE APPLIANCES Metallic framework on a partial denture or
retention pins in a full denture will appear totally radiopaque, the acrylic is slightly radiopaque
ORTHODONTIC APPLIANCES Relatively radiopaque
FOREIGN BODIES
The larger mesial body is a root fragment, while the numerous, fine, more dense particles are remnants of filling material
Root remnant
Fragments of amalgam in the jaw
Broken file appears as a radiopaque structure in root canal
A needle fractured retained in the soft tissues. It is shown superimposed upon the ramus of the mandible
An air gun pellet lodged apparently over the right ramus of the mandible in the region of sigmoid notch.
