There are about 11256 clinical studies being (or have been) conducted in Egypt. 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.
Periodontitis is a chronic condition associated with the inflammatory destruction of the periodontal tissues ultimately leading to tooth loss. Clinically, it is identified by key features such as clinical attachment loss (CAL), bleeding upon probing (BOP), and an increase in probing pocket depth (PPD), and/or gingival recession. Periodontitis is mediated by polymicrobial dysbiosis with keystone pathogens affecting the virulence of the entire biofilm community. The removal of this biofilm and its retention factors is the ultimate goal of clinical treatment and oral measures applied. The elimination of the biofilm has traditionally been achieved with the use of either hand instruments or power driven devices. Promoting periodontal health or diminishing bacterial presence and calculus buildup on teeth can be accomplished with the same efficacy whether using manual scalers and curettes or ultrasonic scaling instruments. Both hand and ultrasonic instruments are characterized by being time-consuming and requiring technical skill, often causing patient discomfort and post-treatment pain, including hypersensitivity resulting from the loss of hard tissue when scaling the tooth surface. Ultrasonic instruments tend to leave a rougher surface behind compared to hand instruments. While effective the current techniques all have their disadvantages. The aim of this study is to evaluate changes in probing depth clinically, Bleeding on probing, Clinical attachment level, Plaque index, Calculus index, Patient pain/discomfort, Patient satisfaction, Cost effectiveness, Treatment time and Number of pockets closed after using AIRFLOW® Prophylaxis Master device with erythritol powder.
Aim of the Work is To determine the significance of the placental thickness and the thickness of the uterine muscle layer at placenta attachment in the prediction of postpartum hemorrhage and to evaluate both of them as as parameters for identifying high-risk patients.
Conventional supplemental oxygen therapy (COT) during upper gastrointestinal (UGI) endoscopy via nasal catheter is considered the standard practice in maintenance of oxygenation and prevention of hypoxia. However, it is still unclear if this oxygen delivery method is optimal in a prolonged (more than 15 minutes) procedure in patients admitted to the ICU. Because of shortage of data in this concern, this prospective, randomized, controlled clinical trial study will aim to evaluate and compare the efficacy of high-flow nasal cannula (HFNC) oxygen therapy versus COT in patients who will undergo prolonged either diagnostic or therapeutic UGI endoscopy in the intensive care unit (ICU) .
The goal of this clinical trial is to test the efficacy of tadalafil in patients with group II pulmonary hypertension with elevated pulmonary vascular resistance (PVR). The main question it aims to answer is: • Can tadalafil improve patients with group II pulmonary hypertension with elevated PVR? Participants will undergo right heart catheterization (RHC) to make sure they are fulfilling the inclusion criteria, then will be asked to take tadalafil 20 mg for two weeks then 40 mg if tolerated for 12 weeks, then participants will be followed up. Investigators will compare the drug group with another age- and sex- matched control placebo group.
Different classifications to describe alveolar ridge defects have been published over the past years but no single classification has been developed concerning soft tissue volume around teeth or dental implants. Moreover, while several studies investigated the effect of various augmentation techniques and materials on soft tissue volume change and volume stability there is a real gap of knowledge regarding how to evaluate the available soft tissue volume and when to consider it sufficient or deficient which would definitely improve clinical decision making and treatment planing. Therefore, our primary aim was to assess the application of a novel classification system based on the correlation between buccal soft tissue volume and gingival biotypes and, also to assess the sensitivity of such novel method.
Corneal topographic parameters in different degrees of obstructive sleep apnea
Investigators aim to compare the effect of zonisamide versus topiramate in migraine by assessing the absolute reduction in MMD in each group, the percentage of patients who achieved ≥ 50% reduction in the monthly headache days frequency compared to the baseline frequency
The goal of this Clinical trial is to evaluate the clinical and radiographic outcomes of using entire papilla preservation technique with and without autogenous bone and injectable platelet rich fibrin in treatment of isolated Intrabony defects in patients with stage III periodontitis.
The most important symptoms of nasolacrimal duct obstruction are excessive tearing and mucoid discharge. The proposed treatment in this regard is dacryocystorhinostomy (DCR) surgery. Therefore, hemostasis is of great significance in performing DCR surgery. In this regard, the reduction of controlled hypotension and the control of hemodynamic responses of the body to stress effectively reduce the bleeding volume during surgery. Hence, there is no enough studies about controlled hypotension in DCR we decided to perform such a comparison between the effect of dexmedetomidine and labetalol in providing controlled hypotension during DCR surgery.
Catheter-related bladder discomfort (CRBD) is a frequent complaint after urinary bladder catheterization which is commonly done in the perioperative period. CRBD shows similar symptoms to overactive bladder (OAB); so, drugs used for the management of OAB could influence symptoms of CRBD. Trospium chloride and gabapentin are effective in managing patient with OAB even the resistant cases. We will evaluate and compare the efficacy of both oral trospium and gabapentin on prevention of CRBD in the postoperative period in the ICU in in patients undergoing spinal surgery and requiring intraoperative catheterization of the urinary bladder.
