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.
Hands have consistently been an important vehicle in the transmission of disease (1). Thus, thorough hand-washing remains the single most important factor in preventing infection specially in hospitals and labs.Twenty-nine non-clinical volunteers (do not work or come in contact with a clinical or hospital setting) that lacked visible skin injuries, eczema or apparent skin disease were used, those subjects were all tested by a material of each of the three used in the study weekly and laboratory tests were done pre- and post washing.All three material were effective , Eugenol extract as effective as the bar and lotion soap. And this was confirmed statistically.Eugenol has a great antibacterial action even in small concentration and t

Show MoreBackground: Avascular necrosis (AVN) is defined as cellular death of bone components due to interruption of the blood supply; the bone structures then collapse, resulting in bone destruction, pain, and loss of joint function. AVN is associated with numerous conditions and usually involves the epiphysis of long bones, such as the femoral head. In clinical practice, AVN is most commonly encountered in the hip. Early diagnosis and appropriate intervention can delay the need for joint replacement. However, most patients present late in the disease course. Without treatment, the process is almost always progressive, leading to joint destruction within 5 years.Treatment of a vascular necrosis depends mainly on early diagnosis which mainly base

The results of diagnosis clarified that there are 45 bacterial isolates belonging to the bacterium P. aeruginosa The examination of the sensitivity of all bacterial isolates was done for elected 45 isolation towards the 11 antibiotic by spread method on the dishes. The results showed that the resistance ratio toward Cefixim, Cefotaxim, Tetracycline, Amoxicillin, Cloxacillin, Methicillin, Erythromycin and Naldixic acid was 77.7, 73.3, 84.4, 82.2, 80, 77.7, 77.7 and 73.3 respectively, While most isolates were sensitive to all o

In this study, the defluoridation capacities of locally available raw waste beef bones have been estimated. Several experimental parameters including contact time, pH, bone dose, fluoride initial concentration, bone grains size, agitation rate, and the effect of co-existence of anions in actual samples of wastewater were studied for fluoride removal from aqueous solutions. Results indicated excellent fluoride removal effeciency up to 99.7% at fluoride initial concentration of 10 mg F/L and 120 min contact time. Maximum fluoride uptake was obtained at neutral pH range 6-7. Fluoride removal kinetic was well described by the ps

Traditional iron supplement has been failed to correct iron deficiency anemia, therefore, the current study aimed to investigate the efficacy and tolerability of new phosphate binder, ferric citrate, in a sample of Iraqi patients with end stage renal disease on maintenance hemodialysis. Method: Prospective, randomized, open label, active controlled trial was conducted in one center for dialysis in Babylon governance. Patients were randomized to receive ferric citrate with dose of 6 g/d and calcium carbonate with dose of 3 g/d for eight weeks.

The World Health Organization (WHO) documented that early detection and screening, when coped
with adequate therapy, could offer a reduction in breast cancer mortality; displaying that the low survival rates
in less developed countries, including Iraq, is mainly attributed to the lack of early detection programs couple
