Study Notes

Dental Imaging and Materials

  • A dental restoration that appears completely radiopaque on a dental image is a gold inlay.
  • Radiolucent refers to a material or structure that allows X-rays to pass through, appearing dark or less dense on a dental image.
  • It is important for the dental professional to interpret dental images while the patient is present to ensure accurate diagnosis and immediate discussion of findings.
  • Gutta-percha appears radiopaque and similar in density to base materials, making it a commonly used material in endodontic therapy.
  • The typical base material of a complete denture is composed of acrylic resin.

Dental Restorations and Materials

  • Cobalt-chromium alloy appears radiopaque and is usually seen with wrought-metal clasps in removable partial dentures.
  • Miniplates and screws appear as thin radiopaque lines and are used in oral surgery to stabilize fractures of the maxilla and the mandible.
  • A cast gold restoration appears completely radiopaque and exhibits a smooth marginal outline.

Cavity Preparation and Restorations

  • The main purpose of a base material in a cavity preparation is to provide a strong foundation for the restoration and protect the tooth from further damage.
  • An amalgam overhang is a type of defect that occurs when excess amalgam is not properly carved away, resulting in a projecting edge of the restoration.
  • A porcelain-fused-to-metal crown appears as a radiopaque restoration with a thin radiolucent line at the cervical margin on a dental image.
