Study of Zn-hydroxyapatite crystals formation and growth on dentine base at ultrasonic influence

Year: 2017, volume 13 Issue: №2 Pages: 260-265
Heading: Stomatology Article type: Original article

Organization: Saratov State Medical University, Yuri Gagarin State Technical University of Saratov
Summary:

The objective: the study analyses the features of spontaneous growth of hydroxyapatite crystals on dentinal substrate using (by the use of) artificially grown Zn-hydroxyapatite combined with ultrasonic treatment. Material and Methods. A dynamic study of dentinal substrate structure was conducted in a certain time interval after standard primary surface treatment of dentin micro-sections, divided into control and experimental groups. Dentin surfaces in the second group were covered by finely dispersed Zn-hydroxyapatite in combination with ultrasonic treatment. The investigation was performed by use of analytical complex based on scanning electron microscope with high resolution SEM Mira II LMU (Tescan) and energy dispersive analysis system. Results. There were revealed the structural changes of dentinal substrate surface overtime period due to directional growth of Zn-hydroxyapatite crystals. Conclusion. The conducted study showed the possibility of formation of the stable structures in the dentinal substrate when using Zn-hydroxyapatite in combination with ultrasonic treatment.

Ontogenesis of the alveolar walls of the tooth germ according to orthopantomography

Year: 2015, volume 11 Issue: №4 Pages: 561-565
Heading: Stomatology Article type: Original article
Authors: Okushko M.R., Suetenkov D.E., Chependyuk Т.А.
Organization: Saratov State Medical University, Pridnestrovian State University n.a. T. G. Shevchenko
Summary:

Objective: to identify changes of the configuration and size of the walls of the alveolar stages of ontogenesis. Materials and Methods. Orthopantomograms studied 196 children aged 5 to 12 years. We used visual and morphometric methods. Results. The data on the three diameters of the dental alveoli (proximal, middle and distal) has been presented, under which subsequently the main stages of age transformation have been highlighted. Conclusion. Transformation of the alveolar walls radiologically determined and its advancing character in relation to the macroprocesses in the germ tooth have made it possible to consider alveolus as one of the leading biological tools of odontogenesis.

Gender features of rheological properties of blood (plasma viscosity, aggregation and deformation of erythrocytes) in patients with chronic generalized periodontitis

Year: 2014, volume 10 Issue: №1 Pages: 56-61
Heading: Physiology and Pathophysiology Article type: Original article
Authors: Kazantsev A.V., Suyetenkov D.Ye.,/Andronoy E.V./, J Firsova I.V.
Organization: Saratov State Medical University
Summary:

The goal is to study gender features of rheological properties of blood in patients with chronic generalized periodontitis (CGP) from mild to moderate severity. Material and Methods. 80 patients (43.8% male) with CGP aged 42±5 years have been studied. 41 patients (43.9% male) experienced mild severity of CGP, and 39 patients (43.6% male) experienced moderate severity. 40 healthy adults (50% male), aged 31±7 years, have been included into the study. Plasma viscosity on shear rate values 300 sec1 to 5 sec1, and rheological features of erythrocytes (aggregation and deformation) have been evaluated. Results. In healthy women and women with mild severity of CGP, plasma viscosity was lower than in the similar group of men. The rheological features of erythrocytes have not gender differences among healthy adults and patients with mild CGP. Increased severity of CGP has been associated with increased plasma viscosity and rheological features of erythrocytes, particularly in men. Conclusion. Plasma viscosity differs in men and women (childbearing age) (healthy subjects and patients with CGP). In women, severity of pathological changes of plasma viscosity and rheological features of erythrocytes have been determined to be lower than in men.

Organization: Saratov State Medical University
Summary:

Objective: to determine the level of dental health in children and adolescents living in the Saratov region. Material and methods. To assess the intensity and prevalence of major dental diseases 1510 patients have been examined by the method recommended by the WHO Collaborating Centre in Russia. Results. A comparative analysis of caries and occurrence of different types of teeth-maxillary anomalies among children aged from 3 to 18 years. Conclusion. The epidemiology of major dental diseases in the Saratov region is characterized by the significant spread of caries from 70 to 94,6% in the different age groups. The proportion of people with malocclusion among the surveyed reaches 46,6%.

Summary:

Purpose: to study the properties of nanostructured coatings in orthodontic implants. Material and methods. Low and average molecular mass chitosan, 3-amynopropil-3-methoxysylan and suspensions of 5 nm and 10 nm gold nano-spheres stabilized with natrium citrate were used for nanocomposed surfaces. 2mg/ml polyethylenamin water solution was used for making the underlayer before putting polyion coverage using «POLYION-1M». The polyion covering dynamics was studied by polyquartz weighing method. Morphology of created layers was studied with atomic microscopy, elements were studied by secondary ion mass-spectrometry. Results. The best transmission among structures of chito-san/metals was showed by low molecular mass of chitosan and 8-1 Onm nanoparticles of metals. Analysis of roughness of surface shows that nanoparticles of gold make the most solid surface on 3-amynopropil-3-methoxysylan underlayer. Conclusion. The development of biocomparative materials in maxillofacial surgery is considered to be effective method of decreasing the risk of post-operative inflammatory complications by local antibacterial effect.
