- 1-2 mm
- 6-7 mm
- 2-3 mm (correct)
Why may a restoration be described as having a 'soggy bottom'?
Why may a restoration be described as having a 'soggy bottom'?
- Inadequate bonding to the tooth structure
- Excessive curing at the top
- Improper polishing of the restoration
- Insufficient curing at the base (correct)
How should 'bulk fill' resin composites be placed in the cavity?
How should 'bulk fill' resin composites be placed in the cavity?
- As a thick layer at the base
- In one large application
- Only on the cavity walls
- In small angled increments (correct)

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.
