Study Notes
Conventional Resin Composites
- Depth of cure for conventional resin composites is approximately 2-3 mm.
Restoration Defects
- A restoration may be described as having a 'soggy bottom' due to inadequate curing of the resin composite at the bottom of the cavity.
Bulk Fill Resin Composites
- Bulk fill resin composites should be placed in 4-5 mm increments in the cavity.
- The purpose of 'flowable' consistency in 'bulk fill' resin composites is to allow for easy flow and adaptation to the cavity walls.
Curing of Resin Composites
- The 470 nm light source should be placed at a distance of 1-2 mm from the surface of the resin composite for efficient curing.
