Study Notes
Dental Restorations on Dental Images
- A gold restoration appears completely radiopaque on a dental image.
- Radiolucent refers to a material that allows X-rays to pass through, resulting in a darker appearance on a dental image.
Density of Dental Restorations
- The most dense and least radiolucent type of dental restoration is a metal-ceramic alloy.
Consequences of Amalgam Overhang
- The most likely consequence of an amalgam overhang is the formation of a plaque stagnation area.
Radiodensity of Various Materials
- Gold restorations appear radiopaque on a dental image.
- An all-porcelain bridge is less radiodense compared to an all-porcelain crown.
- Gutta-percha used in endodontic therapy appears radiopaque and similar in density to base materials.
Denture Base Materials
- A typical denture base material is acrylic resin, which appears radiolucent on a dental image.
Removable Partial Dentures
- The material used in a removable partial denture that appears radiopaque and resembles the radiodensity of dentin is chromium cobalt alloy.
Suture Wires on Dental Images
- Suture wires appear as thin, radiopaque lines on a dental image.
