AIM To evaluate the effect of diode laser and ultrasonics with and without ethylenediaminetetraacetic acid (EDTA) on the smear layer removal from root canals. MATERIALS AND METHODS A total of 120 mandibular premolars were decoronated to working the length of 12 mm and prepared with protaper rotary files up to size F3. Group A canals irrigated with 1 ml of 3% sodium hypochlorite (NaOCl) follow...

Objective: This study aimed to evaluate whether platelet indices and leukocyte count predict the diagnosis of Ethylene Diamine Tetra Acetic Acid induced pseudothrombocytopenia (EDTA-PTCP) differ this entity from immune thrombocytopenia (ITP). Methods: One-hundred sixty-nine individuals (52 patients diagnosed with EDTA-PTCP, 52 newly ITP, 65 healthy individuals) were included. Demographic data c...

INTRODUCTION Elimination of the smear layer after root canal instrumentation requires the use of irrigating solutions. This cleaning can be completed with passive ultrasonic or sonic irrigation. The aim of this study was to evaluate the effectiveness of the EndoActivator System in removing the smear layer after rotary root canal instrumentation, with and without a final flush of 17% ethylenedia...

Abstract This research was focused on the eco-friendly treatment of deep-sea mining tailings in sea areas and mainly dealt with evaluating optimal conditions by comparing aluminum sulfate (AS), which had been proven recently to have an effect as a heavy metal extractant, ethylenediaminetetraacetic acid (EDTA) terms environmental economic feasibility. Harmful metals manganese nodules (2%, w/v) w...

Across many environments, nitrate (NO_3(-)) is an important form of N available for microorganisms and photosynthetic organisms. Accurate NO_3(-) measurements are important for examining N cycling and retention in terrestrial and aquatic ecosystems, but a common method of NO_3(-)) analysis can underestimate NO_3(-)) concentrations when soluble iron is present (iron > 10 mg L(-1)). The basic met...

The purpose of this study was to compare the effects of ultrasonication with ethylenediaminetetraacetic acid (EDTA) and a mixture of tetracycline isomer, an acid, and a detergent (MTAD) as final canal irrigants on the smear layer, debris and erosion scores. Fifty-eight extracted single-rooted human teeth were instrumented with ProTaper rotary files up to size F3. According to the final irrigati...

The present study evaluated the antimicrobial activity of three root canal irrigants against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus. These microorganisms were incubated in the presence of citric acid (6 and 10%), EDTA (17%), and NaOCl (0.5, 1.0, 2.5, and 5.25%). Agar diffusion tests were performed and redox indicator resazurin was used to evaluate the inhibitory effe...

Capsaicin depolarizes primary afferent C-fibers releasing substance P (SP) whose N-terminal metabolites appear to play a role in the development of antinociception. Because some effects of SP(1-7) are similar to those of zinc, we tested the hypothesis that zinc in the extracellular area plays a role in capsaicin-induced antinociception, as measured using the abdominal stretch (writhing) assay. ...

Aim Compare efficacy of Dual Rinse HEDP with sodium hypochlorite to in combination a finishing rinse 17% EDTA solution remove the smear layer. Materials and methods Sixteen human maxillary single-rooted, single canalled sound premolars were used. Specimens distributed into 2 groups labeled according irrigation protocol Each group consisted 8 specimens: Group 1 50% NaOCl followed by EDTA. The Ri...

AIM: This study compared the removal of smear layer using 1% phytic acid or 17% ethylenediaminetetraacetic (EDTA) after root canal instrumentation with SmartTrack X3, Endo*star E, and ProTaper Gold rotary systems an environmental scanning electron microscope (ESEM). METHODS: Sixty single-rooted unidentified extracted human maxillary anterior teeth were selected. The length all roots used was ad...
