OBJECTIVE The aim of this study was to investigate the reliability of visual and digital methods to assess marginal microleakage in vitro. MATERIALS AND METHODS Typical Class V preparations were made in bovine teeth and filled with composite resin. After dye penetration (0.5% basic fuchsin), teeth were sectioned and the 53 obtained fragments were assessed according to visual (stereomicroscope...

Materials Methods: Thirty single rooted mandibular premolars were decoronated standardized at 15mm. The specimens chemo- mechanically prepared, randomized into three experimental groups (n =10) according to root canal sealer tested: Jet and, Bioseal. filled using cone technique. decalcified,...

OBJECTIVE The aim of this study was to compare color stability and surface topography of three different feldspathic porcelains both qualitatively and quantitatively after exposure to routinely consumed beverages over different time periods using a Spectrophotometer, Stereomicroscope and Surface roughness tester, respectively. MATERIALS AND METHODS A total of 90 plastic discs were casted to o...

Abstract The Scuttle fly, Eurygaster integriceps Puton (Hemiptera: Scutelleridae) is a key pest of wheat and barley. univoltine migrates from fields following harvest to high elevations; then, the spring it moves back fields. Natural enemies may have an important role in decreasing population’s level overwintering sites. In present study, adults E. were collected sites Isfahan province, Iran, O...

BACKGROUND To estimate the age by evaluating the area and length of dentin translucency in single-rooted ground sections of extracted teeth using digital Vernier caliper and stereomicroscope. MATERIALS AND METHODS Ground sections of single rooted permanent anterior teeth were made and stained with 1% methylene blue. The area and length of dentin translucency were measured using digital Vernie...
