INTRODUCTION The aim of this in vitro study was to evaluate the effect of an experimental irrigation solution, containing two different concentrations of papain, Tween 80, 2% chlorhexidine and EDTA, on removal of the smear layer. METHODS AND MATERIALS Thirty-six single-rooted teeth were divided into two experimental groups (n=12) and two positive and negative control groups of six. The canals...

OBJECTIVES This study was carried-out to evaluate and compare the efficacy of various irrigants when used singly or in combination on the microhardness of root canal dentin. STUDY DESIGN A total of 50 root-halves were randomly divided into 5 groups immediately after the initial baseline microhardness measurements and treated with: Group-1; 7.5%Ethylenediaminetetraaceticacid (EDTA) + 2.5%sodiu...

Bu çalışmada, sera koşullarında ekmeklik ve makarnalık buğday çeşitlerine farklı Fe form (FeSO4.7H2O; Fe-EDTA; Fe-EDDHA) uygulama şekillerinin (toprak, yaprak toprak+yaprak) tane konsantrasyonuna olan etkisi araştırılmıştır. Elde edilen sonuçlara göre; topraktan (0 5 mg kg-1), yapraktan (%0.2 Fe) , toprak + kg-1 %0.2 yaprak) formu (özellikle Fe-EDTA FeSO4) uygulamalarının çeşitlerinin kuru madd...

Platelet adhesiveness was measured in vitro in a group of patients with ischaemic heart disease and in a group of matched healthy subjects using either 1% EDTA or 3.8% sodium citrate as anticoagulant. When sodium citrate was used platelet adhesiveness was significantly greater in the group with ischaemic heart disease. However, no difference was found when EDTA was used. In both groups platelet...

We performed ultrafast pump-probe spectroscopy of J-aggregates of 3,3'-disulfopropyl-5,5'-dichloro-9-ethyl thiacarbocyanine triethylammonium (THIATS), one of the most typical cyanine dyes, and detected excited molecular vibrations, using a sub-10 fs pulse laser. The time-resolved two-dimensional difference absorption (ΔA) spectra are observed between -314 and 1267 fs. By performing the Fourier ...

BACKGROUND Chelation therapy with sodium edetate (EDTA) improved renal function and slowed the progression of renal insufficiency in patients subjected to lead intoxication. This study was performed to identify the underlying mechanism of the ability of EDTA treatment to protect kidneys from damage. METHODS The effects of EDTA administration were studied in a rat model of acute renal failure ...

BACKGROUND: Metal induced toxicity with wide range of physiological, biochemical and behavioral dysfunctions was reported in many studies. The chelation has been used for treatment to toxic metals’ exposure for many years. In our current clinical study, we compared different chelation protocols and two forms of EDTA (sodium calcium edetate and sodium edetate) in treatments of toxic metal exposu...

This study measured excretion of 11 minerals induced by EDTA chelation therapy in 25 adults (aluminum, cadmium, calcium, chromium, copper, iron, lead, magnesium, manganese, mercury, zinc). We administered 20 EDTA infusions (3 g, with magnesium and ascorbate) 1 to 2 weeks apart and measured 24-hr urinary excretions of minerals before treatment and after treatments 1, 10, and 20. A modest supplem...

Elevated HIV-1 viral load (VL) observed in specimens frozen in situ in plasma preparation tubes (PPTs) compared to EDTA plasma specimens may affect therapeutic monitoring of HIV-infected patients. The increase in viral load is cell associated and minimized when plasma from the PPT is aspirated or recentrifuged prior to freezing. This study investigates the contribution of integrated HIV-1 provi...

This study aimed to compare the effects of ethylenediaminetetraacetic acid (EDTA) and maleic acid (MA) on the sealing ability of various root canal sealers. Eighty root canals were instrumented and irrigated with either EDTA or MA. They were divided into eight experimental groups and obturated as follows: Group 1: MA + Hybrid Root SEAL/gutta-percha. Group 2: EDTA + Hybrid Root SEAL/gutta-percha...
