Bulk-fill materials: simplify restorations, reduce chairtime.

Newer bulk-fill composite materials are being developed for preparation depths of up to 5 mm in an effort to simplify and improve placement of direct composite posterior restorations. Depth of cure for any dental composite is a critical issue, and especially so for bulk-fill composites. This article discusses factors involved in determining adequate depth of cure. Additionally, a case report depicting occlusal decay describes how a highly filled bulk-fill material was used to achieve an esthetic and functional restoration while eliminating incremental composite layering, thereby saving considerable time.
