Belə ki, məhz istehlak əmtəə və xidmətləri bazarı – milli iqtisadi sistemin sosial-iqtisadi əsasıdır və buna əsasən bildirmək olar ki, kommersiya fəaliyyətinin bünövrəsi bu sferada formalaşır. İstehlak bazarının öyrənilməsi istənilən iqtisadi qurumdan, həm bilavasitə əmtəə iehsalçılarından, ticarət vasitəçilərindən, çeviklik, obyektiv bazar şərtlərinə uyğunlaşmaq imkanları və qabiliyyəti, eyni zamanda, müxtəlif kompleksli tədqiqat metodlarının tətbiqi vasitəsilə onlara məqsədli şəkildə təsir mexanizmlərinin axtarışını tələb edir.

Research paper thumbnail of Morphological Assessments of Root Apex of Permanent Mandibular First and Second Premolars in a Turkish Population

The aims of the study were (I) to assess apical morphological data of mandibular first and second premolars in a Turkish population at a young-adult age range (II) to analyze potential correlations between the size and position of the apical foramina (AF). Extracted sound teeth were collected from an adult volunteer population as willing to donate. Morphological data were obtained from specimens using a stereomicroscope. The number, size, shape, and position of AF and frequency of accessory foramina were quantified. Mann-Whitney U and Spearman's rank correlation tests were performed (α=0.05). A total of 237 teeth were investigated. The majority of the specimens had one major AF. The frequency of major AF was between 1–3 for both groups. The median AF size in mandibular first and second premolars were 55,180 µm2 and 67,483 µm2, respectively. The majority of fo...

A twenty-two-year-old healthy female patient was presented. Unilaterally, the dense radiopacity of the maxillary sinus was detected in the dental examination. Radiopaque deposits within the right maxillary sinus, associated with the endodontically treated tooth #16 were monitored with the cone-beam computerized tomography taken as a diagnostic aid. Retreatment with surgery was planned. Following the chemomechanical preparation, orthograde calcium silicate cement (OrthoMTA, BioMTA Co., Seoul, Korea) was grafted into root canals prior to the surgery. The pathologic tissue adjacent to palatal root apices of tooth #16 located in the inferolateral wall of the right maxillary sinus floor was reached in Cadwell-Luc operation. The pathologic tissue was excised and root apices were not resected. Microscopically examination of the material revealed hyphae structures compatible with Aspergillus and furthermore, Aspergillus spp. was grown in microbiological culture. The definitive diagnosis was made as maxillary sinus aspergilloma according to the existing clinical, radiological and microbiological findings. No systemic antifungal treatment was performed in the postoperative period. The tooth has been followed up to 2 years. The asymptomatic clinical condition was maintained and radiographic healing was observed.

Three commercial hydraulic calcium silicate‐based cements and a calcium hydroxide‐based paste were used. Pure‐grade zirconium oxide, bismuth oxide, zinc oxide, barium sulfate, and calcium hydroxide were as references. An energy‐dispersive X‐ray spectroscopy instrument was used for the elemental analysis. Radiographic image data was obtained according to the International Organization for Standardization 6876‐2012 specifications. The region of interest was determined for each specimen. Mean (±SD) grey values of the X‐ray image data was measured with an image analyzing software. The calibration curve was created by curve‐plotting software and the mean grey‐values were matched versus Al values (mm Al). Data were analyzed with one‐way ANOVA followed by Tukey's multiple comparison test. Spectroscopic characterization of the commercial materials was shown with assigned Carbon, oxygen, aluminum, silicon, calcium, zinc, zirconium, barium, tungsten, bismuth, and sulfur elements. The major radiopacifier/s of OrthoMTA is Bi, of RetroMTA is Zr, of BioDentine are Ba and Zr, and of ProCal is Ba. The radiopacity values of all commercial materials are significantly different (p < .05). The rank of the radiopacity values: RetroMTA (3.36 ± 0.29mmAl) > OrthoMTA (2.56 ± 0.19mmAl) > BioDentine (2.02 ± 0.12mmAl) > ProCal (1.46 ± 0.60mmAl). The study reported that the radiopacity values and spectral characterization of RetroMTA and OrthoMTA cements. The pixel‐based and reproducible method could be used universally to the quantification of the radiodensity of digitally collected X‐ray data.

The indexes characterizing the demographics and income, life expectancy, power consumption and quality of life are presented. The dynamics of incomes in Russia is presented in the light of poverty and hunger elimination. A comparative analysis of the quality of life in Russia and the countries with the largest economies in the world (USA, China, Japan, Germany) is conducted. It is shown that in its socioeconomic development of Russia is greatly inferior to such highly developed countries like the US, Japan, Germany. During the considered period of time (24 years) Russia has failed to achieve significant social and economic growth. More than 16 million people live below the poverty line. More than half of the population have per capita income below the national average. In difficult domestic and international conditions, Russia fulfilled its commitments to reduce poverty level and Russian government puts every effort to sustain the achieved position in the socioeconomic life of the population.
