The productivity of olive trees in arid and semi-arid environments is closely linked to irrigation. It is necessary to improve the efficiency of irrigation techniques to optimise the amount of olive fruit produced in relation to the volume of water used. Partial root-zone drying (PRD) is a water saving irrigation technique that theoretically allows the production of a root-to-shoot signal that ...

BACKGROUND Open irrigation and débridement is the standard of treatment for septic arthritis of the wrist. Although isolated cases of arthroscopic irrigation and débridement have been reported, a comparison of arthroscopic and open techniques has not been performed, to our knowledge. The purpose of this study was to compare the two methods of management. METHODS A retrospective comparison of ...

The effects of conservation-tillage practices on the root environment of corn (Zea mays L.) may differ with varying amounts of irrigation. Dryland, 50% irrigation, and 100% irrigation treatments were applied in combination with disc, no-tillage, and a postemergence chisel treatment designed to allow rapid infiltration of irrigation water. The study was conducted during the 1980 growing season a...

PURPOSE To evaluate the alterations on the surface of gutta-percha cones (GPCs) on exposure to the different irrigation solutions and their possible antibacterial effect against Enterococcus faecalis. (E. faecalis). MATERIALS AND METHODS Disinfection ability of different solutions (5.25% sodium hypochlorite, 2% chlorhexidine, 1% peracetic acid, and QMix) were tested with 96 GPCs and the time ...

Background. This in vitro study aimed to compare the antibacterial effect of different concentrations of sodium hypochlorite on elimination of Enterococcus faecalis from root canal systems of primary teeth with or without a passive sonic irrigation system (EndoActivator). Methods. The root canals of 120 extracted single-rooted primary incisors were prepared using the crown-down technique. The t...

INTRODUCTION Several irrigation techniques have been recently introduced with the main objective of improving root canal disinfection. This in vitro study aimed at comparing the intracanal bacterial reduction promoted by chemomechanical preparation with 3 different irrigation techniques. METHODS Root canals from extracted teeth were contaminated with Enterococcus faecalis ATCC 29212 for 7 day...

AIM To compare the apical negative pressure irrigation (ANP) with conventional irrigation in the teeth of immature dogs with apical periodontitis. METHODS Fifty-two immature pre-molar root canals were randomly assigned into 4 groups: ANP (n=15); conventional irrigation (n=17); healthy teeth (control) (n = 10); and teeth with untreated apical periodontitis (control) (n=10). After induction of ...

The present study deals with the performance evaluation of five irrigation subsystems by considering eight different criteria. Two Multi criterion Decision Making (MCDM) methods, namely, stochastic extension of PROMETHEE-2 (STOPROM-2) and Multi-Attribute Utility Theory (MAUT) are employed to select the best one among the five irrigation subsystems. Taguchi methodology is employed to minimize th...

PURPOSE Obstructive and inflammatory disease often occurs in the major salivary glands, and no predictive treatment has yet been developed for this condition. The aim of this report was to introduce an intraductal irrigation procedure and to illustrate its application to practical patient cases. MATERIALS AND METHODS Two patients complaining of pain and swelling in the parotid gland during me...

This study investigated the effect of deficit irrigation at three management allowable depletion levels (MAD) 25%, 50%, and 75% on phytochemicals, ascorbic acid, antioxidant activity, glucose, fructose, and fresh and dry mass in two green leafy lettuce cultivars (Lollo Bionda and Vera) at harvest. Genotype response was observed during deficit irrigation on fresh and dry mass at harvest. Vera re...
