    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.
