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.
