Background: Simultaneous and staged guided bone regeneration (GBR) is one of the several surgical techniques that have been developed in the past two decades to regenerate bone and thus to allow implant placement in compromised sites (fenestration and dehiscence). It is a surgical procedure that consists of the placement of a cell-occlusive physical barrier between the connective tissue and the alveolar bone defect. The treatment concept advocates that regeneration of osseous defects is predictably attainable via the application of occlusive membranes, which mechanically exclude non-osteogenic cell populations from the surrounding soft tissues, thereby allowing osteogenic cell populations originating from the parent bone to inhabit the osseous wound. Augmentation utilizing guided bone regeneration (GBR) has become a major treatment option to provide optimal bone to support Osseointegrated dental implants. One of the objectives of GBR is the formation of new bone at sites deficient in bone volume. Another objective is to treat fenestrations and dehiscence at implant surfaces as well as defects associated with simultaneous implant placement. GBR has allowed for placement of restorations at a more ideal location in the oral cavity, thus improving esthetics and functions. This study aimed to improve the alveolar ridge width by using of synthetic bone substitute covered by resorbable collagen membrane in simultaneous dental implants placement and to compare the ridge width at three levels (crestal, middle and apical) clinically (osteometer) and radiographically (CT) pre operatively and postoperatively. Materials and methods: This prospective study was conducted in teaching dental hospital in College of Dentistry of Baghdad University on (15) patients with (21) dental implant with insufficient bony support for simultaneous dental implants , this study extended from March 2013 to the end of December 2013. All patients were treated at the time of implantation by using a synthetic bone substitute covered by resorbable collagen membrane .All patients examined clinically by osteometer and radio graphics (CT) to assess ridge width and height and bone density. Results: Clinically and radiographically evaluation showed increasing of ridge width after 6 months of healing period at three levels: apical, middle and crestal, statistically, there were no significant differences between ridge width gain measured clinically and radio graphically and gender and age groups. In this study the success rate (95.24) % in (20) dental implant and only (1) dental implant was failed (4.76) % at age 47 years old. Conclusion: There was significant increase in ridge volume that augmented at the time of implantation to become sufficient width for support implant esthetically and functionally. This study revealed that there was no effect in gender and age on bone augmentation with synthetic bone substitute. Keywords: GBR, Simultaneous dental implant, osteometer, CT, ridge width and height and bone density.
In globalization, the world became open area to competition for the attractive of investment, and the abilities of each country to win the confidence of investors depend upon the preparation to optimize circumstances. The competitiveness is an essential means of expanding the capacity of developed to coexist in an international environment characterized by globalization. While competition describes the market structure, the behavior of investors and business, competitiveness is interested in the evaluation of business performance or countries and compare them in the conditions of competition available in these markets. Regarding Malaysia, which is depend on FDI-Export- Led Growth strategy, it has taking on diffe

Abstract- Asymptomatic or clinically silent kidney stones are possibly serious because, in their expected passage, they may cause infection, obstruction and renal impairment. The purpose of this study was to determine the prevalence of silent kidney stones in a sample of Baghdad population and consider how this value could affect the justification for a screening system. To our best knowledge, this is the first study of its kind conducted in Iraq. We investigated 714 consecutive patients who sustained an abdominal ultrasound at our hospital with further kidney screening. All these patients did not have clinical signs and symptoms of nephrolithiasis. Age, sex, the indication for ultrasound, the size, side, and the number of the disco

Background: Helicobacter pylori are important gastrointestinal pathogen associated with gastritis, peptic ulcers, and an increased risk of gastric carcinoma. There are several popular methods for detection of H. pylori (invasive and non-invasive methods) each having its own advantages, disadvantages, and limitations, and by using PCR technique the ability to detect H. pylori in saliva samples offers a potential for an alternative test for detection of this microorganism. Materials and methods: The study sample consists of fifty participants of both genders, who undergo Oesophageo-gastrodudenoscopy at the Gastroenterology Department of Al-Kindy Teaching Hospital Baghdad/ Iraq, during five months period from January 2014 to May 2014. They we
