متن کاملComparison of Bacterial and Dye Microleakage of Different Root-End Filling Materials
INTRODUCTION The provision of an effective apical seal is an essential factor when choosing an appropriate material for success of root-end surgeries. Root-end resection, preparation and obturation should provide an adequate apical seal. The aim of this in vitro study was to investigate bacterial and dye microleakage of four different root-end filling materials and compare the efficacy of these...
متن کاملroot-end filling with cement-based materials: an in vitro analysis of bacterial and dye microleakage
background: one ideal property of a root-end fi lling material is its apical sealing ability. the aim of this in vitro study was to assess bacterial and dye microleakage of white and gray mineral trioxide aggregate (wmta and gmta), portland cement and calcium-enriched mixture (cem) cement used as root-end fi lling material, and to assess the agreement between these two test methods. materials a...
متن کاملAcid Fuchsin Dye Based PMMA Film for Holographic Investigations
In view of a possible application in optical data storage devices, diffraction grating efficiency of an organic dye, Acid Fuchsin doped in PMMA matrix was studied under excitation with CW diode pumped Nd: YAG laser at 532 nm. The open aperture Zscan of dye doped polymer displayed saturable absorption and the closed aperture Z-scan of the samples exhibited negative nonlinearity. The diffraction ...
متن کاملDye Concentrations Determination in Ternary Mixture Solution by Using Colorimetric Algorithm
This publication uses a colorimetric method based on the absorbance spectra of dye solutions to improve on Beer’s law when calculating the dye concentrations of a three-component mixture. The performance of the new method is compared with that of Beer’s law evaluated at three wavelengths, and Beer’s law evaluated at 16 wavelengths. Colorimetric method gives the best prediction of d...
