Clinical behavior of silver-palladium alloy castings: a five-year comparative clinical study.

A 5-year clinical comparison between silver palladium alloys (Albacast and Ney 76) and gold alloy (Firmilay) was conducted. Clinical evaluations for the castings of these materials placed in the same patients, were recorded immediately after cementation, at 3 months, 6 months, 1.5 years, 3 years, and 5 years. The changes in surface tarnish, discoloration, polish, and plaque accumulation was compared. The results indicated that gold alloys responded slightly better than Ney 76 alloy, but similar to Albacast alloy with adequate correlation between the four criteria evaluated.

Cervical enamel crazings associated with occluso-proximal composite restorations in posterior teeth.

Cervical enamel crazing lines were counted after preparing MODBL preparations in freshly extracted maxillary premolars. The teeth were restored with composite onlays. One-third of the restored teeth were left as is. In the second third MD intra-composite staples were prepared. The staples were prepared at 10, 20 and 30 minutes and 24-hour intervals. The craze lines were counted pre- and post-restoratively. Intra-composite staples reduced craze lines substantially. There were no statistical differences between MD and MD-BL staples. Thirty minutes proved to be the maximum time to prepare these staples to have a reducing effect on the number of craze lines.
