Filter by:Several techniques were proposed in the literature to solve the problems associated with gingival recession. Root coverage was mainly indicated for esthetic concern, however, it might also be indicated for treatment of root hypersensitivity and maintaining adequate plaque control by keratinized tissue augmentation. These proposed surgical techniques were well-documented with successful outcomes. Each technique had its own advantages, disadvantages and indications. Various factors affected the most suitable technique. These factors were either related to the dimensions of gingival recession defect, or related to the surgeon experience or to the patient himself . Nowadays, the scope of scientific research is concerned with designing surgical techniques that are more predictable, high esthetic, less invasive and patient centered In this way, continuous modification of surgical techniques aroused to result in a more reproducible outcomes; such as the attempt to advance pedicle flaps without vertical releasing incisions, as in the modified coronally advanced flap and the modified microsurgical tunnel technique. However, controversy still exist in the literature regarding the best technique for root coverage. Coronally advanced flap is the most commonly reported technique in research, with lack of researches on tunneling techniques.
Diarrhea-associated hemolytic uremic syndrome (D+HUS) is defined as a prodrome of enteritis followed by thrombocytopenia (< 150,000/mm3), microangiopathic hemolytic anemia, and signs of variable degrees of renal damage (increase in serum Cr, proteinuria, and/or hematuria) . Our aim is to detect the most reliable early predictors of poor prognosis to identify children at major risk of bad outcome who could eventually benefit from early specific treatments.
This study aims to understand and compare the metabolic and mechanical demands placed on the body while walking normally and walking with the use of an apparatus that drives leg swing through the use of the arms. This information will help the investigators identify how arm swing mechanics helps minimize energy demands and to use this knowledge to design walking rehabilitation interventions in the future.
We aim, in this study, to examine whether reduction of FLT PET derived SUV before and after carbon ion radiotherapy can predict the treatment response and survivals for patients with locoregionally recurrent nasopharyngeal carcinoma.
90 healthy female subjects with regular menstrual cycle ,their ages ranged from 19-25 years,their BMI ranged from 18-25 will be participated in this study. Formetric Raster Stereography will be used to assess spinal configuration while each participant wear shoes of different heel heights 2.5 cm (low),4.5 cm (moderate) and 7 cm (height) during early follicular and mid luteal phases of menstrual cycle.
To record the digital data from monitoring instruments (standard patient monitor) containing cardiovascular system information, and from depth-of-anesthesia monitoring modules (Bispectral index, Entropy module, Surgical Plethysmography Index, Analgesia Nociception Index) containing neurological system information captured in the patient monitor, as well as the physiological data regarding anesthetic dosage, respiratory gas analysis and the standard monitoring requirement of anesthesia. The investigators also record the precise time points of detail surgical steps during the shoulder arthroscopic surgery. Clinical data collected from these monitoring instrument will be used to gain more understanding of the complex interaction between anesthetic effect, surgical procedure, autonomic response and drug modeling. The goal is to obtain the performance of each monitoring index in detail surgical steps.
A single-center randomized controlled study comparing endoscopic or interventional therapy guided by the hepatic venous pressure gradient (HVPG) , to standard endosopic variceal ligation plus nonselective beta-blocker therapy (NSBB) in patients with esophageal varices due to liver cirrhosis with a history of esophageal variceal hemorrhage.Primary study outcome of the study is variceal rebleeding episodes occurring within the first years after interventions. Second study outcomes of the study are hepatic encephalopathy occurrence, mortality occurrence, liver transplantation or other cirrhosis-related complications.
to explore the differential expression of miRNA in the implantation window of patients with endometriosis and the time of progesterone and route of administration on planting window
to evaluate vitreomacular interface abnormalities in diabetic retinopathy by using Ocular Coherence Tomography (OCT)
Implants have become the perfect solution for replacement of missing single teeth, partial or even complete edentulism.18 However, the dilemma of anterior implant-supported prosthesis is still not quite solved.19-21 Implant abutments are one of the esthetic influencers. And concerning the material, ready-made titanium abutments are considered the gold standard of all. Nevertheless, the esthetic properties remain doubtful. Lithium disilicate ceramics have been used as implant superstructures for many years now for their combined esthetic and biomechanical properties. The purpose of the present study is to evaluate the effect of using titanium implant abutment on the color of lithium disilicate crowns and the significance of masking the titanium abutments with opaque porcelain or using opaque lithium disilicate coping on the final esthetic outcome
