ABSTRACT
The vitality of teeth adjacent to dental implants should be considered in the treatment planning of dental implants. Both the restorability of an endodontically treated tooth and the risk of infection of the adjacent implant are important factors in planning for success. Given the illustrated difficulties and difficulties associated with resolving periapical infections of teeth and implants, it is essential to define the vitality of teeth by careful pulp testing and to consider the integrity of existing questionable, endodontically treated teeth before implant treatment. The risk of periapical infection at teeth adjacent to implants must be minimized.

Scleroderma is a multisystem connective tissue disease of unknown etiology, which is characterized by inflammation, vascular, and fibrotic changes of the skin as well as various internal organs. This article will review the systemic form of scleroderma known as CREST syndrome, its clinical manifestations including the dentofacial complications, as well as provide information to assist the prosthodontist in managing the dental treatment for patients with this disease.

STATEMENT OF PROBLEM: Little information has been reported with regard to the dimensional accuracy of improved dental stone materials for reproduction of an entire arch form. PURPOSE: The purpose of this study was to evaluate the ability of an epoxy resin die material and a type IV dental stone to dimensionally reproduce an entire arch form. MATERIAL AND METHODS: Models were fabricated and measurements were made of reference marks to calculate dimensions from first molar to the midline bilaterally and between first molars. Each measurement was repeated three times and the mean measurement and percent relative change was calculated for each dimension. RESULTS: The results revealed that the difference in the relative change in two dimensions was statistically significant for the epoxy resin group (p < 0.05). CONCLUSIONS: The materials provided a similar degree of dimensional accuracy in reproducing a complete arch when used with addition silicone impression material.

STATEMENT OF PROBLEM: Improved dental stone has been widely used for producing dies for the fabrication of restorations with the lost-wax technique. Improved dental stone is used for several reasons, but it is selected most often because of its reasonable cost, ease of use, and ability to produce consistent results. PURPOSE: This study evaluated the ability of an epoxy resin die material and a type IV dental stone to dimensionally reproduce a custom-fabricated metal die. MATERIAL AND METHODS: Dies were fabricated and measurements were made from three reference lines. Measurements were repeated three times for the master die and for the specimen dies. A mean measurement and percent relative change for each dimension was calculated. RESULTS: A significant difference in the relative change for die height was found between the groups studied (p < 0.003). CONCLUSIONS: This epoxy die system will provide a degree of dimensional accuracy comparable to gypsum when used with addition silicone impression material.

The purpose of this study was to evaluate the marginal adaptation of all-porcelain labial margin metal ceramic crowns using a porcelain shoulder material containing a light-polymerizing resin and one that used a direct-lift technique. Conventional metal margin restorations served as controls. Scanning electron micrographs were made of a 1-mm mesiodistal width of the margin at midfacial and midlingual reference marks. Image processing and analysis techniques were accomplished using a computer. Statistical evaluation indicated that the mean labial marginal discrepancy of the control group was significantly less than that of either of the two porcelain shoulder methods.
