There are about 256 clinical studies being (or have been) conducted in Iraq. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.

new technique in targeting V2 under ultrasound guidance
The orthodontist uses plaster models to collect information. This includes identification deviations, classification of malocclusion, formulation of treatment goals for specific patient. Models are used to examine the morphology of individual teeth and also to visualize the placement of teeth in individual dental arches. Study models It therefore appears to be one of the most important records for treatment planning. In USA, orthodontist can start practicing orthodontics which requires a lot of difficulty 300 new cases in a year and therefore may require an entire room to store plaster models. The minimum file retention period depends on the appropriate platform for the statute of limitations during which legal action for fault can be brought. in the USA, this time period varies from 5 to 15 years, varies from country to country. This platform can be started on the last day of treatment, or it can be postponed until the patient reaches adulthood. Regardless of how it is viewed, long term storage is required. Over ten years, if 300 new cases are initiated each year, that will represent 6,000 combinations of prototyping, pre-processing and post-processing. Additional storage space may be required, maybe somewhere else, with financial implications. With the recent introduction of digital models and CBCT images, the orthodontist now has an alternative to traditional plaster study models. Digital technology makes it possible to analyze a computer using software capable of rotating, examining and measuring digital images of the model and dental arches from different points of view. The intraoral scanner is a hand-held device that creates digital impressions of the oral fossa and displays it in 3D on a computer screen after being processed by the scanning program for each device. By 1985 the first intraoral scanner was available for commercial use, and over time it had evolved to become smaller, faster, and more accurate. Intraoral scanners provide easier treatment planning, better workflow, greater patient acceptance and shorter working time, but more studies are needed to investigate their accuracy and compare with traditional methods. The measurements of the tooth widths are one of the important elements in orthodontic diagnosis because of its role in calculating the partial and total Bolton ratio, the Ton relationship, and space analysis. Therefore, the aim of this study will be to assess the accuracy and reliability of measuring teeth widths and Bolton ratios based on three mains well -known methods (plaster models, CBCT images and intraoral images) to ensure the safety of orthodontic diagnostic outputs.
Antepartum hemorrhage (APH) due to placenta previa is an important cause of worldwide perinatal mortality and maternal morbidity in pregnant women
Randomized split mouth clinical trials study focused on comparing the efficacy of i-prf versus c-prf injections on gingival thickness and keratinized tissue width in subjects with thin gingival biotype.
CAD/CAM systems have assisted orthodontists in planning and positioning brackets to minimize errors and improve the excellence of treatment. This study aimed to validate measurements obtained from manual and digital systems, as well as evaluate the effectiveness, and periodontal changes that occurred after the treatment. Materials and Methods: This study is a prospective randomized controlled trial, in which clinical evaluation of virtual setup (digital and manual) techniques versus CAD/CAM brackets (Ormco© Insignia™ .022" twin brackets) in terms of expression of bracket prescription and treatment outcome. The sample consisted of 30 young adults with Angle Class I malocclusion. Cone beam computer tomography (CBCT) were obtained before and after the treatment to assess the parallelism between the dental roots and periodontal conditions. Digital impression by three dimensional (3D) intraoral scans (IOS) will be obtained for all participants. The 3D models are converted to stereolithography (STL) for all groups. The sample will be dividing randomly into three groups; the first one treated with CAD/CAM brackets (Ormco© Insignia™ .022" twin brackets), while the other two groups were treated by customization of bracket base of the conventional pre-adjusted twin bracket with orthodontic adhesive material, this will be done through planning and creating the virtual setup by using Maestro® 3D Ortho Studio software. The Indirect bonding devices for the second group will manufacturing from 3D printed models while third group from the manual double-layer vacuum-formed thermoplastic trays. All patients will treat with fixed orthodontic twin brackets appliances. The 3D models of the Virtual setup are comparing with the treated occlusion. The linear and angular measurements are performing by the Geomagic® software and using the 3Shape's Ortho-Analyzer TM software in all groups to assess the American Board of Orthodontics grading system scores. Random errors are assessing by Intra-class Correlation Coefficient (ICC) and method errors. Descriptive statistical analysis, Shapiro-Wilk test to detect the normality of variable distribution and the Chi-square test evaluated whether the ABO scores measurements are within the limits of agreement of each criterion. ABO scores between both groups are analyze by using Wilcoxon test. The Bland-Altman analysis evaluated if differences are within the limits of agreement.

A randomized clinical trial to compare the effectiveness of newly designed active type of presurgical orthopedic appliances on maxillary arch dimensions in infants with bilateral cleft lip and palate.
Studying the effects of adding probiotics to the drug regimen of patients with diarrhea predominant IBS
Aim and objectives This study aimed to treat fractures of the distal end of the radius in the children with Robert Jones (RJ) bandage in comparison with a cast. The objective was to compare the frequency of occurrence of the complications, child comfortability, and family satisfaction with this treatment modality.
