Degradation of resin–dentin bonds using NaOCl storage

Dental Materials, 2003
Several recent studies have reported collagen hydrolysis within bonds over the long-term. This may be one reason for the degradation of the bonds. This study therefore aimed to determine the effects of NaOCl on adhesive system bonds (total-etch bonding system vs.

Cytotoxic effects of NaOCl on vital tissue

Journal of Endodontics, 1985
The cytotoxicity of various dilutions of sodium hypochlorite was evaluated using three independent biological models. Dilutions as low as 1:1000 caused complete hemolysis of RBC's in vitro. Undiluted and 1:10 dilutions produced moderate to severe irritation to rabbit eyes which healed after 24 to 48 h. Intradermal injections of undiluted, 1:1, 1:2, and

A Comparison of the Antimicrobial Efficacy of NaOCl/Biopure MTAD versus NaOCl/EDTA against Enterococcus faecalis

Journal of Endodontics, 2006
The purpose of this investigation was to compare the antimicrobial efficacy of irrigating with 1.3% NaOCl/Biopure MTAD versus irrigation with 5.25% NaOCl/15% EDTA in the apical 5 mm of roots infected with Enterococcus faecalis. Bilaterally matched human teeth were sterilized and inoculated with E. faecalis. After chemomechanical root canal preparation,

Oxidation of Huolinguole Lignite with NaOCl

Advanced Materials Research, 2013
Huolinguole lignite (HL) was oxidized with aqueous NaOCl solution under mild conditions. The oxidation products were analyzed by GC/MS. In total 111 products from the HL oxidation were detected, most of which were benzene polycarboxylic acids and short-chain alkanoic acids, while a predominant chlorinated compounds such as trichloromethane ...

The effect of NaOCl dentin treatment on nanoleakage formation

Journal of Biomedical Materials Research, 2001
The term "nanoleakage" has been introduced to explain a penetration pathway within hybrid layers of the dentin-composite junction in the absence of gap formation. This phenomenon is argued in the literature to be a risk factor for the quality of the dentin bonding.

Comparison of the Antimicrobial Efficacy of 1.3% NaOCl/BioPure MTAD to 5.25% NaOCl/15% EDTA for Root Canal Irrigation

Journal of Endodontics, 2007
The purpose of this study was to compare the antimicrobial efficacy of 1.3% NaOCl/BioPure MTAD to 5.25% NaOCl/15% EDTA for root canal irrigation. Twenty-six bilaterally matched pairs of human teeth were collected. The teeth were incubated with Enterococcus faecalis for 4 weeks.

Effect of simulated intraosseous sinusoidal pressure on NaOCl extrusion

Journal of Dentistry, 2018
The present study examined the effects of irrigant flow rate and simulated intraosseous sinusoidal pressure on the rate of NaOCl extrusion from the apical terminus of a faux root canal.An extrusion setup was designed to enable irrigant extrusion to be opposed by 30 mm Hg simulated intraosseous pressure.

The use of NaOCl in combination with CHX produces cytotoxic product

Clinical Oral Investigations, 2013
The combination of sodium hypochlorite (NaOCl) and chlorhexidine (CHX) yields a "precipitate potentially toxic" (PPT). The aim of this study was to evaluate the tissue response to implanted polyethylene tubes filled with PPT-soaked fibrin sponge.Forty rats received four polyethylene tubes each; each tube was filled with fibrin sponge soaked by 2.5 ...

GaAs Polishing Mechanism with NaOCl Solution

Journal of The Electrochemical Society, 1989
A wafer (100) surface was polished with solution. Surface analyses have been accomplished by Fourier‐transform infrared spectroscopy (FT‐IR), x‐ray photoelectron spectroscopy (XPS), Auger electron spectroscopy (AES), and Raman spectroscopy. Reaction between and was found to produce product. Ten minute soaking in solution caused a 420A thick reaction as

What About On‐site NaOCl Generation?

Opflow, 2001
This month's question concerns the feasibility of generating sodium hypochlorite (NaOCl) at a remote well site; specifically, what the required concentrations of feed solutions are, the life of the generated product, and any disposal issues. On‐site sodium hypochlorite generation (SHG) systems are premanufactured and can be purchased as a skid‐mounted ...
