There are about 252 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.
Peri-implantitis is a non-linear and accelerating pattern of loss of supporting bone tissue associated with clinical signs of inflammation and increased probing depths compared to baseline measurements. It can present as an asymptomatic condition with infection and fast progression of bone resorption or clinically symptomatic with mucosal inflammation, redness, edema, mucosal enlargement, bleeding on probing (BOP), suppuration, increased probing depth, and radiographic bone loss. The host immune defense against bacterial challenge is responsible for the damage, and the local immune-inflammatory process is associated with disrupted bone remodeling. New studies looking for predictive and accurate early biomarkers for this pathology have the utmost relevance. David Baltimore et al. proposed a feedback loop involving miRNA-146a and TLR signaling, which has been shown to be up-regulated in inflammatory diseases such as osteoarthritis and rheumatoid arthritis. miRNA-146a and miRNA-155 were the first miRNAs identified to be induced in immune cells stimulated by TLRs and proinflammatory cytokines. Precision medicine uses molecular research and different biomarkers, population studies, and big data analysis to recreate complex disease models. Several studies have compared the miRNA profiles of patients with periodontitis with healthy patients. Although periodontitis and peri-implantitis share many features, researchers' findings of periodontitis are not necessarily applicable to peri-implantitis. In fact, based on emerging evidence, peri-implantitis, and periodontitis exhibit several key differences, including their histopathological and molecular characteristics. Considering the aforementioned analysis, inflammatory miRNAs may be differentially expressed in peri-implantitis tissue compared with healthy gingival tissue. This study will investigate the gene expression levels of miRNA-146a and miRNA-155 and their correlation with inflammatory levels of their target genes in human gingival tissue surrounding dental implants diagnosed with peri-implantitis and health.
Periodontitis is a chronic inflammatory disease characterized by both dysbiosis of oral microbiota and proinflammatory events involving both cells and mediators from innate and adaptive immunity. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. These events lead to chronic inflammation of periodontal soft and hard tissues sharing many features with other chronic inflammatory diseases. Chronic inflammation is driven by various mediators, of which a significant part is attributed to the interactions within cytokine networks. While proinflammatory cytokines, including interleukin (IL) -1α, IL-1β, TNF-α, IL-6, and IL-17, contribute to acute and chronic inflammation and tissue injury, a second group with antagonist effects is formed by cytokines such as IL-10
Aim of the study: This study aims to evaluate the antioxidant and beneficial effects of matcha tea daily intake on periodontal health. Objectives: - To evaluate the salivary level of antioxidants (catalase, total antioxidant capacity) after matcha tea intake compared to green tea over a period of one month. - To evaluate the clinical periodontal parameters including bleeding on probing (BOP), probing pocket depth (PPD) and plaque index (PI) after matcha tea intake compared to green tea over a period of one month. - To evaluate the salivary levels of IL-1B after matcha tea intake compared to green tea over a period of one month.
the main aim of the study is to evaluate the secondary implant stability when using dental implants with injectable platelet rich fibrin accompanied by non-autogenous bone graft material in narrow ridge cases versus straightforward ridges , in clinical comparative study.
The aim of this study is to evaluate the effect of Osseodensification on implant stability during the healing period The objective of this study is to compare between dental implant stability after osteotomy site preparation using osseodensification technique and conventional drilling technique immediately after implant installation (primary stability) , 6 week after the insertion of implant and 12 weeks later (secondary stability)
To assess if there are any differences among platelet-rich plasma, hyaluronic acid, and corticosteroid knee intra-articular injection regarding function and pain.
The objective of this study is to test the scale structure, reliability, validity and responsiveness to change of the QLQ-CML24 in conjuction with the QLQ-C30 for patients diagnosed with CML, and to investigate longitudinal relationship between satisfaction with information provision and QoL outcomes.
One-lung ventilation (OLV) with resting of the contralateral lung may be required to allow or facilitate thoracic surgery. However, OLV can result in severe hypoxemia, requiring a mechanical ventilation approach that is able to maintain adequate gas exchange, while protecting the lungs against postoperative pulmonary complications (PPCs). During OLV, the use of lower tidal volumes is helpful to avoid over-distension, but can result in increased atelectasis and repetitive collapse-and-reopening of lung units, particularly at low levels of positive end-expiratory pressure (PEEP). Anesthesiologists inconsistently use PEEP and recruitment maneuvers (RM) in the hope that this may improve oxygenation and protect against PPC. Up to now, it is not known whether high levels of PEEP combined with RM are superior to lower PEEP without RM for protection against PPCs during OLV. Hypothesis: An intra-operative ventilation strategy using higher levels of PEEP and recruitment maneuvers, as compared to ventilation with lower levels of PEEP without recruitment maneuvers, prevents postoperative pulmonary complications in patients undergoing thoracic surgery under standardized one-lung ventilation.
Stress-related disorders are among the most prevalent and expensive medical consequences of participation in military operations. Omega-3 fatty acids EPA/DHA derived from fish oil are known to benefit both neuronal development in the young, and cognition and mood in various populations. It is possible that soldiers receiving Omega-3 EPA/DHA will exhibit significantly higher cognitive performance, better affect/mood state, and less combat stress symptomatology compared to the placebo after 12 weeks of supplementation. A goal would be to reduce the prevalence of combat stress injuries in military personnel.
