abstract the present thesis studies different question sentences in persian and russian languages comparatively. sentence is a syntactic unit that matches a lot of dimensions together. sentence includes syntactic structure definite meaning & concept and different applied demotions. in applied, question and imperative sentences based on speakers aim. predicative sentences state a kind of info...
background: endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to gutta-percha in respect to obturation procedure. the aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system. materials and methods: a total of 42 teeth were selected and w...
Measurement of chlorophyll-a can be considered important to investigate the primary production of an ecosystem. This study aimed to investigate chlorophyll-a concentration, primary production and the factors affecting them in Shadegan Wetland located in Khouzestan Province - Iran. Sampling for measuring (NO3, PO4, BOD5, DO, pH, EC, salinity, temperature) was performed seasonally at five samplin...
Baobab trees are often cited in the literature as water-storing trees, yet few studies have examined this assumption. We assessed the role of stored water in buffering daily water deficits in two species of baobabs (Adansonia rubrostipa Jum. and H. Perrier and Adansonia za Baill.) in a tropical dry forest in Madagascar. We found no lag in the daily onset of sap flow between the base and the cro...
introduction: the aim of this in vitro study was to compare the canal transportation of two single-file engine-driven systems, neoniti and reciproc, using cone-beam computed tomography (cbct). methods and materials: forty-five non-calcified roots with mature apices and apical curvature of 15-30 degrees were selected from extracted human maxillary molars for this study. samples were randomly div...
Background and Objective: The preparation of the root canal (i.e., cleaning and shaping) is the main step in the endodontic treatment. The nickel-titanium rotary files result in fewer errors during the preparation of curved canals. This study aimed to compare the transportation of Neolix and Reciproc rotary systems in curved canals using cone beam computed tomography (CBCT). Materials and Meth...
Background and Aims: To ensure root canal treatment success, endodontic microbiota should be efficiently reduced. Several irrigation devices have been recently introduced with the main objective of improving root canal disinfection.The purpose of this study was to evaluate the rinsing effect of RinsEndo system in reduction of enterococcus faecalis in comparison with conventional hand syringe ...
Background and Objectives: The anatomy of maxillary molars is very complicated and root canal therapy for this specific group of teeth is a major challenge for dentists. Given the limitations of conventional techniques for finding the second mesiobuccal canal (MB-2) and anatomical differences observed in different ethnicities, this study aimed to determine the anatomy of mesiobuccal root canal ...
