Microleakage reduction using glass-ceramic inserts.

Thirty human non-carious specimens were used in this in vitro study. The specimens were divided into three groups of 10 each: Group 1: incremental fill: Group 2: Beta-Quartz glass-ceramic inserts: Group 3: pre-cured resin composite inserts. All restorations were placed with TPH resin composite. The specimens were thermocycled and sectioned. Microleakage was determined on a scale of 0 (no microleakage) to 5 (microleakage extending to the axial wall). Results of the study indicated that Beta-Quartz glass-ceramic inserts and incrementally placed resin composite restorations exhibited significantly less microleakage compared to pre-cured resin composite inserts (P < .03, Chi-Square Test).

Restoration of a cracked tooth with a bonded amalgam.

The diagnosis and treatment of the cracked tooth can present difficulties. The causes of the cracked tooth include masticatory accident, radical preparation and overuse of direct restorative materials, trauma from occlusion, and torque on abutment teeth. Placement of a cast restoration covering the cusp is usually suggested. However, bonded restorations are effective in restoring the strength of teeth weakened by cavity preparation. A material that bonds amalgam to dentin may present a more conservative and less expensive restoration of the cracked tooth.
