Radiographic Appearance of Dental Materials and Foreign Objects Chp 23

These flashcards focus on key terms and their definitions related to the radiographic appearance of dental materials and foreign objects.

Radiopaque

Materials that are dense enough to block X-ray penetration, appearing white or light on a radiograph.

Radiolucent

Materials that allow X-rays to pass through, appearing dark on a radiograph.

Amalgam

A dental material made of silver and other metal alloys used to restore decayed or damaged teeth.

Gold alloy

A metallic dental material used for restorations, known for its durability and esthetics.

Stainless steel crown

A temporary restoration often used for primary teeth, characterized by its lower density that results in a see-through appearance.

Fixed bridge

A dental restoration consisting of pontics and abutments to replace missing teeth.

Retention pin

A metal pin used to support a dental restoration, appearing radiopaque on X-rays.

Post and core

A structure used in endodontically treated teeth to support a crown, with a metal post cemented into a root canal.

Dental liner

A material used to protect the pulp in dental restorations, providing a barrier underneath fillings.

Composite resin

A tooth-colored material used for esthetic restorations, varying in radiopacity.

Glass ionomer

A dental material that releases fluoride and is used as a liner, cement, or sealant.

Porcelain fused to metal (PFM) crown

A type of dental crown that combines metal for strength and porcelain for esthetics.

Ceramic porcelain crown

A full coverage crown made entirely of porcelain, providing an esthetic solution without a metal base.

Gutta percha

A material used to fill emptied pulp canals after a tooth's nerve is removed.

Foreign objects

Unintentionally or intentionally introduced materials within the oral cavity, which may appear on radiographs.

Orthodontic materials

Stainless steel, titanium, ceramic, or composite materials used in braces and other orthodontic applications.

Implant

A titanium screw surgically inserted into bone to replace a missing tooth.

Amalgam tattoo

A localized area of pigmentation in tissues due to amalgam fragments, which can appear on radiographs.

Dental cement

A material used to adhere restorative materials to teeth or to assist in retention.

Bacterial overhangs

Excess material that can trap bacteria and food, found at the margins of dental restorations.

Temporary restoration

A provisional solution used on teeth, typically until a permanent restoration can be applied.

Endodontic filling

Materials used to fill root canals in endodontically treated teeth.

Crown margins

The edges of a dental crown that should seamlessly fit against the natural tooth structure.

Radiographic appearance

The visible characteristics seen on X-ray images that help in diagnosing dental materials.

Collapsed tooth structure

The loss of natural tooth due to decay or damage before placement of a restoration.

Pontic

The part of a fixed bridge that replaces a missing tooth, suspended between abutments.

Bracket

A device used in orthodontics that holds the arch wire of braces in place.

X-ray density

The measure of how much a material can block X-ray penetration, influencing its appearance on radiographs.

Intraoral radiographs

X-ray images taken within the mouth to assess dental health and restorations.

Restorative dentistry

A field of dentistry focused on restoring the function and integrity of diseased or damaged teeth.

Marginal integrity

The quality of the junction where a restoration meets the tooth structure, critical for preventing decay.

Radiopacity gradient

The variation in radiographic appearance based on the density of different dental materials.

Oral cavity assessment

The examination and evaluation of the mouth, teeth, and associated structures.
