Influence of ceramic thickness and polymerization mode of a resin luting agent on early bond strength and durability with a lithium disilicate-based ceramic system.

Statement Of Problem: Attenuation of polymerization light energy by translucent all-ceramic materials may result in insufficient polymerization of underlying resin luting agents and inadequate early bond strength and durability. There is little information regarding the selection of an appropriate polymerization mode for cementing translucent all-ceramic restorations.

Purpose: The purpose of this study was to evaluate the influence of ceramic thickness and polymerization mode on the early bond strength and bond durability of a lithium disilicate-based ceramic system.

[Quantification of hepatic arterial and portal venous flow using ultrasound contrast agents for early detection of liver metastases of colorectal cancers].

Purpose: To quantify liver blood flow using US contrast agents and to evaluate arterial and portal changes in control patients and patients with liver metastases.

Materials And Methods: Twenty eight patients were included in this study, 8 controls (M0) and 20 patients with liver metastases from colon carcinoma (M+). Hepatic blood flow from hepatic artery and portal vein were determined using quantification of enhancement after contrast injection using Power Doppler US.

[Value of sonography in the diagnosis and follow-up of patients with cryptogenic inflammatory bowel diseases in current practice: review of a 10-year experience in a community hospital].

Inflammatory bowel diseases (IBD) are chronic inflammatory diseases of the bowel that are of unknown etiology. These diseases either progress with intermittent flare-ups interrupted by periods of remission or on a chronic active progressive mode. IBDs include Crohn disease (CD) and ulcerative colitis (UC).

A multi-centre study of Osseotite implants supporting mandibular restorations: a 3-year report.

This multi-centre study evaluated the performance of the Osseotite implant in the mandibular arch. Osseotite implants (n = 688) were placed in 172 patients; 43.5% were placed in the anterior mandible and 66.
