introduction: the aim of this study was to evaluate the effect of proximal contour of class ii composite restorations placed with straight or contoured matrix band using composite resins with different modulus of elasticity on stress distribution by finite element method. methods: in order to evaluate the stress distribution of class ii composite restorations using finite element method, upper ...

Abstract The implant-supported removable partial dentures should be an alternative to conventional removable partial dentures and implant-supported fixed partial prostheses when the implant’s insertion is confined by bone height and thickness. Placing a single implant in the posterior region would modify the Kennedy Class II configuration to a Kennedy Class III and increase the stability a...

Background: A common Human Leukocyte Antigen (HLA) class II allele, DQβ1*03:01, seems to be associated with Bullous pemphigoid (BP) in Caucasians whereas previous studies in other ethnic groups showed other HLA class II alleles as genetic predisposing factors for BP. Objective: To investigate the association of HLA class II alleles and haplotypes with BP in Iranian population. Methods: Fifty pa...

abstract aims: the increasing usage of antibiotics can cause resistance to the treatment of infections, which can caused by bacteria, e.g. pseudomonas aeruginosa. the aim of this study was to trace the class i, ii and iii integrons in isolates of p. aeruginosa of nosocomial infection and determining the antibiotic resistance pattern of the bacteria. instrument & methods: in this cross-sectional...

By means of computer-based statistical methods, several types of Class II malocclusion have been discovered with defining horizontal and vertical characteristics. Of the six horizontal types, four are severe syndromes, one is a loose, ill-defined grouping of cases with mild skeletal features, and one has only the dental features of Class II. Five vertical types associates with Class II were als...

statement of problem: due to the appearance of palatal height difference in orthodontic patients we decided to carry out this study. purpose: the purpose of this research was to determine palatal height in persons with normal occlusion and different malocclusions (class i, ii div i and iii) and comparing them with each other. materials and methods: in this cross sectional research, 240 subjects...

background: thalassemia is probably the most common single gene disorder causing a major public health problem in the world. currently, allogenic hematopoietic stem cell transplantation (hsct) is the only curative therapy for thalassemia. one major limitation of hsct is the lack of hla-identical sibling donors, so attention has turned to finding phenotypically matched unrelated donors. patients...
