The relative biologic efficacy of intraperitoneal (IP) insulin administration over peripheral routes of insulin infusion for artificial delivery devices is still poorly documented. Thus, the effects of IP insulin administration have been compared with the effects of subcutaneous (SC) insulin administration upon circulating fuel metabolites, hormones and(More)
PURPOSE The purpose of this study was to evaluate the clinical performance of In-Ceram Zirconia posterior fixed partial dentures (FPD) after 3 years in service. MATERIALS AND METHODS Eighteen In-Ceram Zirconia FPDs were fabricated in 16 patients. The FPDs were placed between January and April 1999. The CDA quality evaluation system was used for assessment(More)
STATEMENT OF PROBLEM Marginal discrepancies of zirconia posterior fixed dental prostheses (FDPs) fabricated using various systems have been assessed to determine the quality of the restorations and facilitate clinical use; however, studies are limited and results are ambiguous because of the sample sizes and measurement methods. PURPOSE The purpose of(More)
The aim of this study was to assess the implications of dual infection with hepatitis B virus (HBV) and hepatitis C virus (HCV). The HBV and HCV status in 100 patients with chronic hepatitis was analysed. HBV DNA was studied using liquid hybridization and the polymerase chain reaction (PCR). HCV viremia was measured using qualitative and quantitative PCR.(More)
STATEMENT OF PROBLEM Although the favorable mechanical properties of zirconium oxide-based ceramics have increased the acceptance of fixed dental prostheses for use in the posterior regions of the mouth in recent years, there are few clinical studies documenting the longevity of these restorations. Furthermore, certain complications must be resolved before(More)
The purpose of this study was to compare two measurement methods for the external marginal fit of zirconia posterior fixed partial dentures (FPDs) fabricated using computer-aided design/manufacturing technology and metal-ceramic posterior FPDs fabricated using the conventional lost-wax technique. The null hypothesis was that there would be no differences(More)
PURPOSE This study aimed to compare the marginal fit of 2 kinds of metal-ceramic crowns-crowns cast from commercially pure titanium and Procera titanium crowns. MATERIALS AND METHODS Ten copings of each type were prepared, veneered with low-fusing porcelain, and bonded with glass-ionomer cement. Marginal fit was assessed before and after cementation, and(More)
The aim of this study was to investigate the marginal fit of posterior fixed partial dentures (FPDs) made with 2 computer-aided design/computer-assisted manufacture systems--Procera Bridge Zirconia (Nobel Biocare) and Lava AllCeramic System (3M ESPE)--and to analyze the differences between abutments and between buccal and lingual surfaces. Twenty(More)
OBJECTIVES To assess the prevalence and significance of HCV infection in patients with chronic active hepatitis B. METHODS We studied clinical and histological activity in 132 patients with chronic active hepatitis B, 17 of whom were co-infected by HCV. Serum HBV-DNA was determined by dot-blot hybridization and polymerase chain reaction (PCR) and serum(More)
OBJECTIVE To compare intraperitoneal implantable insulin infusion (IP) to subcutaneous (SC) intensive insulin therapy. RESEARCH DESIGN AND METHODS Twenty-one insulin-dependent (type I) diabetic patients aged 24-61 yr underwent a 3-mo treatment optimization using multiple SC daily injections or external pumps. Patients were then randomized (time 0 mo) to(More)
