Interface seal of incremental placement of visible light-cured composite resins.

An investigation was conducted to determine the quality of seal at the interface when a visible light-cured composite resin was placed and cured in increments. Five samples of each of the following composite materials were tested: Aurafill, Command, Command Ultrafine, Durafill, Prisma-Fil, and Silux. Samples of each material were placed in a thermocycling dye bath that contained a 0.5% aqueous solution of basic fuchsin dye for 25 hours. The samples were removed from the dye bath, rinsed, dried, and prepared for examination with a x25 microscope by two examiners. Neither examiner reported dye penetration at the interface of the materials tested. These findings effectively highlight the practicality of the incremental placement of light-cured composite resins.

Interface strength of incremental placement of visible light-cured composites.

The strength of bond at the interface was determined when a visible light-cured composite resin is immediately added to a previously cured surface. In general, small particle composites (Aurafill excepted) tend to lose a small amount of strength at the interface, whereas the microfilled and hybrid composites do not.

The use of radiographs in small cast-gold restorations.

The rationale for the use of treatment radiographs in the construction of cast-gold restorations has been presented. Radiographs are made in the University of Louisville Fixed Prosthodontics Clinic at the precementation and postcementation stage of treatment when casting margins are inaccessible. Radiographs at this stage of treatment permit detection and correction of a variety of problems that may not be discovered clinically and allow the construction of excellent cast-gold restorations that would be impossible otherwise. Because all radiation safety factors are observed, the amount of radiation a patient receives is minimized.

Cost analysis of relined mercaptan rubber impressions.

An investigation was conducted to compare the time and amount of material used in a corrective reline impression procedure and in a complete remake of a new double-mix impression. The reline technique required 22.22 gm less material, and the reline technique was achieved in approximately 7.6 minutes less time than that required for a complete remake. This results in a monetary saving while preserving quality.
