Background. Elimination of bacteria from the root canal system is one of the aims of endodontic treatment; hence the incorporation of antibiotics into sealers can increase their antimicrobial efficacy. The aim of the present study was to determine the in vitro antimicrobial effects of AH26 and AH Plus sealers mixed with amoxicillin, triple antibiotic paste and nanosilver on Enterococcus faecali...

OBJECTIVES To evaluate clinically and radio graphically, the healing following nonsurgical treatment of periapical lesions when Photo Activated Disinfection(PAD), triple antibiotic paste and calcium hydroxide was used as root canal disinfectant. MATERIAL AND METHODS Sixty patients (20 for PAD, 20 for triple antibiotic paste, 20 for calcium hydroxide) with periapical lesions in the maxillary a...

An important requirement for endodontic paste with antibiotics placed in direct contact with living tissues is biocompatibility. The aim of this study was to evaluate the paste biocompatibility prepared with zinc oxide (1.25mg), tetracycline (8mg) and thiamphenicol (26.67mg). The paste and its components were implanted separately through polyethylene sterile tubes of 10mm in length and 1.3mm in...

Abstract The chloride binding capacity of cement paste with Mg-Al CLDH, obtained through calcining a commercial LDH, is investigated under different concentration, environmental temperature, and concrete pore solution alkalinity conditions. transformation mechanism CLDH to Mg-Al-Cl LDH mainly explored by means X-ray diffraction (XRD) , Fourier-transform infrared spectroscopy (FT-IR) Differentia...

Raw pulses as extenders in meat preparations result oxidative processes. The effects of using a raw chickpea paste (CP; 1/2; chickpea/water) pork patties were evaluated. In first experiment, prepared with increasing levels CP (0 to 25%); second (25%) and without (controls) kept at 4 °C or 22 for 18 h before patty production; third chitosan, garlic, cumin (from 0.5 2%) added controls, their anti...

We present here some results provided by a multiscale resolution method using both Finite Volumes and Finite Elements. This method is aimed at solving very large diffusion problems with highly oscillating coefficients. As an illustrative example, we simulate models of cement media, where very strong variations of diffusivity occur. As a by-product of our simulations, we compute the effective di...

Powerful digital image editing tools make it very easy to produce a perfect image forgery. The feather operation is necessary when tampering an image by copy-paste operation because it can help the boundary of pasted object to blend smoothly and unobtrusively with its surroundings. We propose a blind technique capable of detecting traces of feather operation to expose image forgeries. We model ...

The application of martensitic stainless steel in gas turbine blades, bushings, valves and mine ladder rungs requires wear and corrosion resistant surfaces. The process of boronizing can produce extremely hard and wear resistant surfaces for such components. The study depicts the application of Taguchi based desirability analysis for parameter design in the process of boronizing martensitic sta...

A Hysitron Triboindenter has been used to determine the mechanical properties of hardened cement paste and cement paste at the early age. This technique provides an in-situ scanning probe microscopy (SPM) imaging facility that allows pre and post-test observation of the sample. The same probe is used to indent and image eliminating the complicated situation of locating the same area with differ...
