Composites

A set of flashcards covering key concepts related to composites in dentistry, including types, properties, procedures, and potential issues.

What are composite resin restorative materials used for in dentistry?

They are primarily used for direct restorations and provide aesthetic enhancements.

What are the three types of composite resin curing methods?

Chemical-cured, light-cured, and dual-cured.

What is an advantage of using fillers in composite resins?

Fillers improve the strength, wear resistance, and other physical properties of the composites.

Why is incremental placement of composite resin recommended?

It helps to minimize polymerization shrinkage and improves the adaptation to cavity walls.

What factors determine the light-curing time for composite resin?

Factors include the thickness of the composite increment and the type of lamp used.

What is a key property that distinguishes microfilled composites from macrofilled composites?

Microfilled composites have smaller filler particles, which provide a smoother finish and better aesthetics.

What is the purpose of using eye protection during light-curing of composites?

To prevent potential damage from the intense light emitted by curing units.

What are packable composites primarily used for?

They are used for posterior restorations due to their greater strength.

What are the components of a composite resin?

They consist of an organic resin matrix, inorganic filler particles, silane coupling agent, initiators, accelerators, and pigments.

What are some common reasons for composite failure?

Fracture of the restoration, recurrent caries, and both owner and operator errors.
