Sir, We read with great interest a letter to editor, leprosy: An urgent need to step up surveillance by Dev et al.[1] As leprosy is an old disease of social stigma, disabilities, and deformities caused by low virulent mycobacterium leprae and the disease have been eliminated at the national level in December 2005, there are still cases from various districts and blocks that make a prevalence ra...

A lot of push-out tests of shear studs embedded in normal strength concrete were conducted. So current design code methods of the shear studs are based on the test results of studs embedded in normal strength concrete. It also appeared that the strength of connector and the concrete strength are the main factors affecting the behavior of shear connections. But push-out test data of studs embedd...

BACKGROUND This study examined the effects of addition of 10% and 25% by weight calcium hydroxide on the physicochemical properties of Portland cement associated with 20% bismuth oxide in order to develop a new pulp capping material. MATERIAL AND METHODS The solubility, pH value, setting time, compressive strength, and push out bond strength of modified Portland were evaluated and compared to...

background: during endodontic procedures, the smear layer is formed as a result of mechanical instrumentation of the canal. combination of ethylenediamine tetraacetic acid (edta) and sodium hypochlorite (naocl) is widely used for removal of the smear layer. application of mixture of tetracycline, acid, and detergent (mtad) as final irrigant subsequent to initial irrigation of 1.35% naocl has be...

In recent years many research on composite beams with innovative shear transmission with composite dowels have been conducted and innovative composite constructions have been built. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite b...

OBJECTIVE The aim of this in vitro study was to evaluate the bond strength of different root canal sealers to dentin. MATERIAL AND METHODS Forty extracted single-rooted human teeth were examined and the coronal and middle thirds of the canals were prepared with a 1.50 mm post drill (FibreKor Post System, Pentron). The teeth were allocated in two experimental groups, irrigated with 2.5% NaOCl+...

INTRODUCTION The purpose of this study was to compare the push-out bond strength of white ProRoot Mineral Trioxide Aggregate (MTA), Biodentine, calcium-enriched mixture (CEM) cement and Endosequence Root Repair Material (ERRM) putty after exposure to blood. METHODS AND MATERIALS A total of 96 root dentin slices with a standardized thickness of 1.00±0.05 mm and standardized canal spaces were r...
