AIM This in vitro investigation aimed to study by means of scanning electron microscope the morphological changes in hard dental tissues after using several different methods for caries removal and cavity preparation. MATERIALS AND METHODS Twenty freshly extracted human teeth with carious lesions were used in the study. They were assigned to four groups depending on the method used for prepar...

introduction: the mechanisms of hepatic encephalopathy are not fully understood. moreover, there is no comprehensive data concerning the effects of nitric oxide (no) system on anxiolytic-like behaviors induced by bile duct ligation (bdl). methods: male mice weighing 25-30 g were used and anxiety-like behaviors were tested using hole-board task. results: the data indicated that cholestasis incre...

the effects of substituents on the symmetry and the nature of halogen bonds in [n∙∙∙x∙∙∙n]+-type systems are presented for the yc5h4n∙∙∙x∙∙∙nc5h5 (y = no2, cn, h, ch3, och3, oh, nh2, x = cl, br, i) complexes. some structural parameters, energy data and electronic properties were explored with the density functional theory (dft) calculations. in addition, electrostatic potentials were used in es...

Objective: to estimate the incidence of recurrent myocardial infarction, stroke, and mortality in patients with different phenotypes infarction against background chronic obstructive pulmonary disease. Materials methods: 325 were examined: 195 disease 130 without We studied markers endogenous intoxication: molecules average mass, hematological indexes intoxication, blood gas composition, apopto...

Introduction: We have investigated cardiac SPECT with slant hole collimator in which the holes are slanted towards the target organ, to provide greater sensitivity over the parallel hole collimator. In addition, parallel hole collimator was used to obtain a comparison in FWHM, sensitivity, Compton and photoelectric area values in the simulations. Materials and Methods...

Background: The review presents the scientific state of art in field cementation crowns on implants. Because semipermanent cements have been specially developed for implants, question arises whether this cement group offers an advantage compared to other available and widely used everyday clinical practice. Various factors play a role retentive strength superstructures implants should therefore...

Lack of retention and stability prosthesis coupled with poor masticatory effectiveness is one the most frequent problem faced by edentulous patients. In Present case,using a "Access post over denture system" preferable than using overdentures that are supported teeth in past. A conservative strategy for root preservation was used fabrication access overdenture, which both well-retentive aesthet...
