There are about 65 clinical studies being (or have been) conducted in Syrian Arab Republic. 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.
This experimental study will evaluate the effect of corticision on accelerating the leveling and alignment of lower crowded incisors compared with the control untreated group using cone beam computed tomography. The study sample will consist of 26 patients with less than 6 mm crowding. The sample will be allocated randomly into two experimental groups. The brackets and passive SS wire will be applied with radiographic metal guides between each tooth to allow for accurate corticision site 2 mm below the gingival papilla and to prevent tooth roots injury. The dentoalveolar changes occurring after leveling and alignment of lower anterior teeth will be evaluated using CBCT radiographs, Frequency, degree of root resorption, and the incidence of bone dehiscence will be assessed in relation to initial situation.
Aim: The aim of this study to Assess the healing process of the immediate implant loading with two different provisional techniques (direct and indirect). Materials and methods: 20 implant in the aesthetic zone either in the incisor or in the canine area and excluding the lateral location and then immediate loading is achieved for the 20 implants (10 for direct and 10 for indirect method) Clinical Aspect :color change , healing and bone resorption Esthetic assessment and patient acceptance will be assessed using specific tools. Lab aspect: surface roughness and Marginal fit will be measured to have clue vision.
This study aims to evaluate and compare the skeletal, dental and soft tissue changes, the levels of pain and discomfort and the effect on periodontal health and teeth vitality associated to traditional corticotomy and flapless corticotomy in the retraction of upper anterior teeth. 40 patients requiring extraction of maxillary first premolars and maximum anchorage to retract the upper anterior teeth will participate in the study. They will be divided randomly into two groups : flapless corticotomy (20 patients) and traditional corticotomy (20 patients). Pre-retraction, corticotomy will be performed in the maxillary anterior segment. The skeletal, dental and soft tissue changes will be performed using lateral cephalometric radiographs which will be obtained pretreatment, pre and post en-masse retraction of the anterior teeth and we will also use the dental casts to evaluate the dental changes.
This experimental study will evaluate the effect of combined treatment with low-intensity pulsed ultrasound (LIPUS) and functional appliances (twin-block) on the correction of class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with class II malocclusion. The sample will be allocated randomly into two groups: control group and experimental group. The functional appliance (twin-block) will be applied for all patients, while the low-intensity pulsed ultrasound (LIPUS) will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre and post- treatment changes for each group will be evaluated individually, and the two groups will be compared.
This experimental study will evaluate the effect of combined treatment with low-level laser and functional appliances (twin-block) on the correction of Class II malocclusion, compared with the control group treated with functional appliances (twin-block) only. The study sample will consist of 40 patients with Class II malocclusion. The sample will be allocated randomly into two groups: a control group and an experimental group. Functional appliance (twin-block) will be applied for all patients. Low-level laser will be applied for the experimental group only. The skeleto-dental changes occurring after functional treatment will be assessed using cephalometric radiographs; pre- and post- treatment changes for each group will be evaluated individually.
Is to determine if SDM laser can reduce macular thickness in non central CSME and stop the progression of non central CSME to central CSME in compare to glycemic control
This experimental study aims to evaluate the efficiency of the orthodontic removable traction appliance in the treatment of skeletal class III malocclusion. The study sample will consist of 44 patients with skeletal class III malocclusion. The sample will be allocated randomly into two groups: experimental group and control group. The dentoskeletal changes will be assessed by using lateral cephalometric radiographs before treatment and after obtaining 3mm positive overjet.
Determining the efficacy of low dose of PPI in management acute peptic ulcer bleeding
We aim to assess the treatment outcomes following upper incisors retraction accelerated by corticotomy procedure. So, we intend to randomize orthodontic patients with class II division I malocclusion into two groups: experimental group and control group. Both groups will start orthodontic treatment. Once a 0.019*0.025-inch stainless steel wire is fully engaged to the brackets, 1st premolars will be extracted. Canines will be retracted in the conventional manner. Then, the actual evaluation period starts when the upper incisors are retracted using two different methods.
68 healthy children from the Department of Pediatric Dentistry at Damascus University who require treatment for their primary maxillary second molars will be randomly assigned into one of two groups: experimental or control groups. In the experimental group, a lidocaine hydrochloride-epinephrine hydrochloride nasal spray will be applied to anesthetize upper second molar before the commencement of treatment. To assess the efficacy of this kind of anesthesia, a specific scale will be used by an external observer after capturing some video files of the performed treatment. To assess the safety of this procedure, vital signs will be recorded before and after treatment. Acceptance of the nasal spray will be recorded based on the child's behavior before and after treatment using Frankl scale. If anesthesia was not sufficient to proceed with the procedure, a rescue anesthesia would be used. Rescue anesthesia consists of an infiltration injection of lidocain hydrochloride 2% with epinephrine hydrochloride (1:100,000). In the control group, an intra-oral lidocaine-epinephrine injection will be applied due to treatment. Safety, efficacy and acceptance will be assessed in the same manner to what is performed in the experimental group.
