to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...

Introduction: various irrigation devices and chemical solutions are being developed improved nowadays for better penetration deep into the complex root canal system. Activation of irrigating enhances solution effectiveness. Evidence in literature suggests that ultrasonic is much more effective this respect than syringe alone. Passive (PUI) and/or ultrasonically activated (UAI): nowadays, two te...

AIM To study the effect of intraocular irrigating solutions on the barrier property of the retinal pigment epithelium (RPE). METHODS The isolated rabbit RPE-choroid mounted on Ussing-type chambers under short circuit conditions was used. According to a previous study, the inward (from the choroid to the vitreous side) permeability of the tissue to carboxyfluorescein was adopted as a quantitat...

INTRODUCTION Endodontic treatment removes all pathogens, such as Enterococcus faecalis from pulp and root canals. The aim of this study is to assess the usefulness of sodium hypo-chlorite (NaOCl) in removing E. faecalis from the root canal used with three different irrigation methods. MATERIALS AND METHODS This study was conducted on freshly extracted maxillary incisors. After biomechanical p...

The combination of sodium hypochlorite (NaOCl) and chlorhexidine (CHX) forms a precipitate. The aim of this study was to evaluate the effect of irrigating root canals with a combination of NaOCl and CHX on root dentin and dentinal tubules by using the environmental scanning electron microscope (ESEM) and a computer program (Photoshop CS2). Forty-four extracted single-rooted human teeth were ins...

Calculus formation on tooth surfaces is analogous to the formation of lime and scale deposits in plumbing. Magnetic water devices have been shown to significantly reduce scale deposits in industry; therefore an oral irrigator with a magnetic water device may have a similar effect on calculus. To test this hypothesis, a double-blind clinical study was established using 64 irrigators, 30 of which...
