AIM To assess the presence of Enterococcus faecalis after root canal treatment in single or multiple visits in an ex vivo model. METHODOLOGY Forty-five premolar teeth were infected ex vivo with E. faecalis for 60 days. The canals were then prepared using a crowndown technique with System GT and Gates-Glidden burs and irrigated with 2% chlorhexidine gel. The specimens were divided into five gr...

The optimal management of prolonged priapism for patients with sickle cell anemia (SCA) has not been established. We prospectively studied in an outpatient setting the efficacy and safety of a procedure that employs aspiration of blood from the corpora cavernosa and irrigation with a dilute epinephrine solution under local anesthesia to relieve priapism in young patients with SCA. If hydration ...

OBJECTIVES The objective of this study is to compare antimicrobial effect of irrigation with chlorhexidine gluconate (CHG) to saline in an animal model. METHODS This study used a segmental defect rat femur model contaminated with Staphylococcus aureus and treated 6 hours after injury with debridement and irrigation with 60 mL of fluid delivered at low pressure. In study groups of 10 animals e...

statement of the problem subgingival irrigation with an antimicrobial agent after scaling and root planing (srp) is assumed to be able to kill the bacteria left behind after mechanical debridement. 3% h2o2 is used in the treatment of periodontal disease and it has been shown effective in killing anaerobic pathogens. purpose the aim of this study was to evaluate the clinical effects of subgingiv...

The idea of irrigation is not new, irrigation stems as far back as the Egyptians and probably further in unrecorded history. Even the idea of automated irrigation is not new, mankind has figured out how to irrigate large areas of foliage through the use of automated and drop irrigation systems. Efficient, automated irrigation systems, which can irrigate plants to a desired level and supply thos...

Precision irrigation in fuzzy control system based on crop water stress acoustic monitoring was designed in the paper. Moreover, conventional double fuzzy control model was found to carry out two work mode, normal irrigation and precision irrigation, which aims to both ensure normal growth of crops and achieve effective water-saving. Since five input signals affect output in different degree, t...

in order to investigate the effect of different irrigation regimes on yield and leaf proline content of a spring isfahan local variety of safflower, a field experiment was conducted as split plot in randomized complete block design with three replications at the research station of shahrekord university in 2013-2014. the main factor consisted of four different irrigation regimes (irrigation aft...

Aim To evaluate the antibacterial effect of sonic- and ultrasonic-activated irrigation on bacterial reduction a dual-species biofilm in root canals compared to nonactivated laboratory study. Methodology Two hundred forty extracted human single-rooted maxillary anterior teeth were divided into two main groups (G, n = 120) according initial preparation size canal (G1: 25, 0.06 taper, G2: 40, tape...
