Some facts about composite filling:
Direct dental composites are placed by the dentist in a clinical setting. Polymerization is accomplished typically with a hand held curing light that emits specific wavelengths keyed to the initiator and catalyst packages involved. When using a curing light, the light should be held as close to the resin surface as possible, a shield should be placed between the light tip and the operator’s eyes, and that curing time should be increased for darker resin shades. Light cured resins provide denser restorations than self-cured resins because no mixing is required that might introduce air bubbleporosity.
Direct dental composites can be used for:
- Filling cavity preparations
- Filling gaps (diastemas) between teeth using a shell-like veneer or
- Minor reshaping of teeth
- Partial crowns on single teeth
