background and aims. the aim of present study was to investigate pulp-dentin complex reactions following direct pulp capping (dpc) with calcium hydroxide [ca(oh)2] and simvastatin as pulp-capping materials in the primary human molars. materials and methods. 120 primary molar teeth which had to be extracted for orthodontic reasons were randomly allocated into four groups. group ι as a control, u...

statement of problem: various surgical procedures have been used to achieve root coverage and subepithelial connective tissue graft (sctg) is identified as one of the most successful techniques. recently, acellular dermal matrix allograft (adma) has been developed as a substitute for sctg to avoid removing the palatal connective tissue. purpose: the present study compared the clinical efficienc...

statement of problem: nowadays mineral trioxide aggregate (mta) is widely used for root end fillings, pulp capping, perforation repair and other endodontic treatments. investigations have shown similar physical and chemical properties for portland cement and root mta with those described for mta. purpose: the aim of this in vitro study was to evaluate the tissue reaction to implanted mta, portl...

introduction: high prevalence of rhinoplasty in the community and lack of structured studies about its minor skin and soft tissue complications, point out the necessity of performing precise and comprehensive studies. the aim of this study was to determine the frequency of minor cutaneous and soft tissue complications of rhinoplasty.  materials and methods: 110 patients (30 male and 80 female, ...

abstract background and objective: celiac is an autoimmune disease that is characterized by an immune-system-related damage in the intestinal tissue after consumption of gluten. there is not any general agreement for gold standard. the purpose of this study was the evaluation of specificity and sensitivity of anti-endomysial (ema) and anti-tissue transglutaminase (ttg) serological test compared...

introduction: as the ability to repair cartilage tissue in body is limited, finding a suitable method for cartilage regeneration has gained the attention of many scholars. for this purpose, scaffold structure and morphology, along with cell culture on it, can be a novel method to treat cartilage injuries, osteoarthritis. methods: in this study, polyhydroxybutyrate (phb) is selected as the scaff...

the b cell is a vital contributor to humoral immunity. the b cell-specific antigen cd20 is expressed during b cell development, starting at the pre-b cell level and persists through b cell differentiation, but is lost during terminal differentiation to plasma cells. rituximab is a monoclonal antibody that destroys both normal and malignant b cells that have cd20 on their surfaces and is therefo...

background and aim: iron overload in patients with thalassemia major is one of the most important complications of this disease and its cardiac complications are the most important causes of death in these patients.mri t2 is the perfect device to assess the amount of iron deposited in the heart of thalassemia patients, but it causes waste of time and also is an expensive diagnostic method. tiss...

background: in most cases, prostatitis can be caused by a bacterial agent such as ureaplasma urealyticum. considering to the cumbersome of the culture method for the detection of ureaplasma species in clinical samples such as prostate; pcr method that is faster and more appropriate than the cultivation methods, can be utilized for the detection of u. urealyticum and u. parvum. pcr-rflp method c...
