Документ Analysis of the dynamics of functional occlusion indicators in the construction of occlusion surfaces of orthopedic structures(Aluna, 2020-12) Yarova, S. P.; Turchenenko, S. O.; Tkachenko, I. M.; Yarov, Y. Y.; Ткаченко, Ірина МихайлівнаThe aim: Is to evaluate the effectiveness of the proposed method of constructing occlusal surfaces of orthopedic structures by monitoring the dynamics of functional indicators of occlusion and the functional condition of the masticatory muscles. Materials and methods: The object of the study was made up by 64 patients with included defects of the dentition of the 3rd class according to Kennedy. Patients were divided into two equal groups - the main group (patients were treated by using the suggested method of construction of occlusal surfaces of orthopedic structures) and control (dentition defects were replaced according to the traditional protocol). Results: The results of evaluating the effectiveness of the proposed method showed that the index of symmetry of the anterior bundles of the temporal muscles dropped by 18,5%, the index of symmetry of the masticatory muscles reduced by 22%, the torque of the mandible reduced by 32%, the index of stabilizing occlusal - by 27%, relative efforts of balance disturbance for more than 10 % regarding the left and right reduced by a factor of 4.4, the rate of opening time was 1.5 times higher than before, the rate of time of opening of the jaws -1.8 times. Conclusions: The use of the suggested method of orthopedic treatment with temporary structures leads to probable changes in the studied functional parameters in comparison with the control group (p <0,05).Документ Application of antiseptic and osteoplastic drug for destructive peridontitis treatment(Aluna, 2019) Lyashenko, L. I.; Lobach, L. M.; Petrushanko, V. M.; Nazarenko, Z. Y.; Tkachenko, I. M.; Ляшенко, Лілія Іванівна; Лобач, Лариса Миколаївна; Петрушанко, Володимир Миколайович; Назаренко, Зоряна Юріївна; Ткаченко, Ірина МихайлівнаIntroduction: Treatment of destructive forms of chronic periodontitis is extremely topical. Its relevance is associated with the features of treatment, which depends on the stage of the exacerbation process. The issue of the problem is also in the fact that the destructive seat of periodontitis is a source of chronic infection. The aim:The task of the research was to evaluate the conservative treatment of chronic destructive forms of periodontitis with a dental kit “Cupratin”, developed for professional usage in dental practice. Materials and methods: “Cupratin” is a complex medicament based on suspensions of calcium hydroxide, copper-calcium hydroxide and powder, which contains hydroxide aluminosilicate and calcium sulphate, radiopaque filler. It has bactericidal and osteoplastic effect. The treatment involved 44 patients (44 teeth) in the age group of 37 to 50 years suffering from chronic granulating periodontitis without concomitant diseases. Patients were divided into two groups: investigated and control. In the main group of patients, a suspension on the basis of copper-calcium was used for treatment (root canals were filled with “Cupratin” as a temporary filling material). Obturation of canals was preceded by chemical and mechanical treatment. The medical material was in direct contact with periodontal tissues for 20-55 days. Intraoral X-ray radiography was taken from the patients within the intervals of 3 and 6 months. Results and conclusions: Positive results were obtained, which were characterized by the disappearance of subjective symptoms, intensive bone tissue reconstruction in the site of destruction and a decrease in the size of the destruction respectively.Документ Applying of chlorine-containing antiseptic extracted from sodium troklosene in complex treatment of chronic generalized parodontitis(Українська медична стоматологічна академія, 2018) Lyashenko, L.

The role of anterior teeth in the process of rehabilitation(Aluna, 2019) Tkachenko, I. M.; Vodoriz, Y. Y.; Marchenko, I. Y.; Shundryk, M. A.; Korol, D. M.; Gurzhiy, O. V.; Ткаченко, Ірина Михайлівна; Водоріз, Ярослав Юрійович; Марченко, Ірина Ярославівна; Шундрик, Марина Аркадіївна; Король, Дмитро Михайлович; Гуржій, Олена ВікторівнаIntroduction: Abrasion of teeth significantly affects electromyography results. Analyzing electromyograms of patients who needs complex rehabilitation, it is necessary to note absence of dissociation of the structure, appearance of spontaneous activity in one of the muscles, presence of the prevailing chewing side, appearance of low-amplitude oscillations in biocurrents. The aim: The purpose of this study was to determine the role of anterior teeth in the rehabilitation of patients with increased abrasion. Material and methods: The experimental group involved patients (men and women) aged 20 to 59 years with increased abrasion of teeth I-III degrees. Patients were provided with all the necessary complexes of rehabilitation measures: direct restorations with composite materials using the adhesive system of the Vth generation (in case of light abrasion), indirect ceramic restorations (severe abrasion). All work was conducted in accordance with the Declaration of Helsinki (1964) and was approved by the Ethical Committee of the academy. Results: Activity of the right masseter muscle was slightly higher than that of the left one (313.42 ± 97.96 ms. against 226.69 ± 35.39 ms. respectively). At the same time the resting time of the left and right masseter muscles slightly differs (300.57 ± 30.93 ms. and 307.96 ± 49.47 ms. respectively). Conclusions: Rehabilitation of patients with increased abrasion using combined methods (direct composite restorations with the adhesive system of Vth generation and indirect ceramic restorations), give the possibility to restore the masticatory function (evidenced by an increase in the activity of right and leftmasseter muscle on 2%, a decrease in the rest phase on 20% almost and an increase in amplitude on 2.9%).Документ Changes in the functional condition of the masticatory muscles with increased teeth abrasion(Aluna, 2019) Pavlenko, S. A.; Pavlenkova, E. V.; Tkachenko, I. M.; Sidorova, A. I.; Vodoriz, Y. Y.; Samoylenko, A. V.; Павленко, Світлана Анатоліївна; Павленкова, Олена Вікторівна; Ткаченко, Ірина Михайлівна; Сидорова, Алла Іванівна; Водоріз, Ярослав Юрійович; Павленко, Светлана Анатольевна; Павленкова, Елена Викторовна; Ткаченко, Ирина Михайловна; Сидорова, Алла Ивановна; Водорез, Ярослав ЮрьевичIntroduction: The term “pathological abrasion” (increased abrasion) can be described as a loss of tooth hard tissue on the occlusal, oral, vestibular surfaces of teeth or in the occlusal area. Treatment of increased abrasion of teeth is a difficult task for the practical work of a dentist. The choice of the optimal treatment plan provides the greatest likelihood of long-term success and minimal probability of complication appearance. The aim of our work was to study the functional activity of the masticatory muscles in the pathogenesis of the development of increased abrasion of tooth hard tissues. Materials and methods: In order to achieve the goal of the study, an examination of patients aged between 19 and 69 years old was carried out in order to identify the number of persons with increased abrasion of teeth. During the examination of all patients one control and one researched group were formed. The patients of the control group (30 patients aged from 18 to 60 years) which had intact dental rows with any signs of increased tooth wear. The investigated group consisted of 25 patients, aged from 18 to 60 years. Depending on the complex treatment, the patients of the second group were divided into two subgroups. Subgroup 2A - (10 patients) with increased abrasion of tooth hard tissues with planned complex treatment of the disease without additional use of mouthguards after the end of treatment. For the patients from the 2B subgroup (15 people with increased abrasion of tooth hard tissues) a mouthguard was prescribed after the end of the complex treatment. In order to study some peculiarities of the muscular activity of the maxillofacial region an electromyogram was taken from all participants before treatment and repeated in a six- and twelve-months term. Results and conclusions: In our opinion, all manifestations of increased tooth abrasion are associated with changes in the muscular system, the motor apparatus and the nervous activity of the body. Regarding to this, the study of the propria muscular system and the related bone system can justify the usage of one or another prevention or treatment of the pathology. Based on the results of our research, we can conclude that the study of the functional state of the muscle complex is a fairly reliable prognostic sign in the study of such a disease as an increased tooth abrasion.Документ Clinical features of influence of different groups of bleaching agents in the oral cavity at different periods after the end of the treatment(Полтавський державний медичний університет, 2022) Dvornyk, A. V.; Dvornyk, V. M.; Vodoriz, Y. Y.; Skripnykov, P. M.; Tkachenko, I. M.; Дворник, Анна Валентинівна; Дворник, Валентин Миколайович; Водоріз, Ярослав Юрійович; Скрипников, Петро Миколайович; Ткаченко, Ірина МихайлівнаThe purpose of the study was to assess the clinical changes in the oral cavity after using teeth bleaching systems of different compositions. Totally 65 patients were examined. All patients were 20 to 40 years old and had no severe dental and somatic pathology. This clinical study evaluated the effectiveness and side effects of two products for teeth bleaching. The difference in clinical indicators after the bleaching procedure with the selected gels on the microelement structure of oral liquid was detected. We noticed a significant difference in calcium and sodium indices in the oral fluid. Teeth bleaching agents cause tooth sensitivity manifested by changes in the oral fluid viscosity, pH, and the micronutrient composition. Depending on the bleaching agent used, the teeth bleaching procedure should be completed with remineralizing therapy.Документ Dental caries: Clinical, diagnosis, complications, prevention(Вищий державний навчальний заклад України «Українська медична стоматологічна академія», 2015) Сидорова, Алла Іванівна; Сидорова, Алла Ивановна; Sidorova, A.

M.; Kindiy, D. D.; Toncheva, K. D.; Korol, M. D.; Tkachenko, I. M.; Король, Дмитро Михайлович; Кіндій, Дмитро Данилович; Тончева, Катерина Дмитрівна; Король, Михайло Дмитрович; Ткаченко, Ірина МихайлівнаValid diagnostic assessment of the state of dentoalveolar system and its masticatory function, in particular, is considered to be an important scientific task of modern prosthodontics. Plenty of the developed ways are based on the use of up-to-date information technology, especially on computer analysis of graphic data. The development of the enhanced methods for the evaluation of masticatory efficiency in patients with both full and partial adentia urged the search of its clear and informative indicators. According to the authors, digital image fractal dimension index can meet these needs. Since most of the available masticatory function assessment methods involve the obtaining large ammount of fragments different in their quantity, size and shape. The photography of the multiplicity of these ‘spasmodically’ located objects allows the processing ofthe received image with the help of graphic editor and converting it into numeric data. Thus, the aim of the research was to study the fractal dimension of the masticatory test images, taking into account the peculiarities of the patients’ denture defects. computer software for digital image processing ImageJ 1.50b was used in the research, since it provides the option of computer calculation of the fractal dimension index. The comparison of the masticatory tests of 30 persons with intact teeth (control group) and 33 persons with denture defects has revealed statistically significant deviation in their fractal dimension index. The reduction of the range of conventional statistical norm (1.49-1.66) to the values fluctuating from 1.47 to 1.51. was observed. Therefore, the decrease of the mean value of the fractal dimension from 1.56 (St.Err.= 0.02) to 1.50 indicates the reduction of chopping function in the given masticatory test patterns. As a result, the suggested method will allow the use of fractal dimension index as an integral indicator of masticatory efficiency level.Документ Differential drug correction cytokine and prostaglandin content in blood and gingival fluid in generalized periodontitis against the background of different responsiveness of the organization(Aluna Publishing, 2023-09) Yarov, Yu.; Tkachenko, I.; Skripnikov, P.; Pavlenkova, O.; Pavlenko, S.; Яров, Юрій Юрійович; Ткаченко, Ірина Михайлівна; Скрипников, Петро Миколайович; Павленкова, Олена Вікторівна; Павленко, Світлана АнатоліївнаThe aim is to study the dynamics of prostaglandins and cytokines in the blood and gingival fluid against the background of differential drug correction in patients with generalized periodontitis with different body reactivity. Materials and methods: 216 people aged 45 between 55 years with a diagnosis of generalized periodontitis of II, III degree of severity, chronic course were examined. Depending on the state of reactivity of the organism, the patients were divided into three groups: the first one consisted of people with normoreaction; the second group included patients with hyperreaction; the third group was made up of people with hyporeaction. The patients underwent patch surgery after the initial therapy. Initially, on the 1st, 2nd, 4th, 6th and 9th day after the operation, the content of prostaglandins (PG) E, E2, F2alpha and cytokines (IL-1β, IL-6, TNF, IL-4) in the blood and gingival fluid was performed. Patients with impaired body reactivity were treated with the proposed differential drug correction of cytokines and prostaglandins. Statistical processing of the obtained digital data was performed using the computer program Statistica 8.0. Results: The proposed differential drug correction in patients with generalized periodontitis against the background of hyper- and hyporeactivity of the body brings the content of IL-1β, IL-6, TNF, IL-4 to that of normal body reactivity, which ultimately restores the disturbed balance of pro- and anti-inflammatory cytokines in the blood and gingival fluid. On the 9th day, the content of all proinflammatory cytokines in the main groups was normalized and was commensurate with that of the body’s normal response (p>0.05). Differential drug correction led to normalization of the prostaglandin balance index on day 9 after flap surgery (p>0.05), indicating the establishment of a normal balance of eicosanoids in the blood and approximating the values of pro- and anti-inflammatory fractions of prostaglandins to those of normal body reactivity. Conclusion: Correction of altered parameters in patients with generalized periodontitis accompanied by impaired (hyper- and hypo-) reactivity of the body with bringing them to values that are typical for normoreactivity is considered to be a condition for optimizing mucosal wound healing after surgery and further stabilization of periodontal tissues.Документ Effects of professional oral hygiene and teeth whitening on the microelement composition of enamel(Aluna Publishing, 2023) Dvornyk, A. V.; Vodoriz, Ya. Y.; Pysarenko, O. A.; Marchenko, I. Y.; Tkachenko, I. M.; Дворник, Анна Валентинівна; Водоріз, Ярослав Юрійович; Писаренко, Олег Анатолійович; Марченко, Ірина Ярославівна; Ткаченко, Ірина МихайлівнаAim: The objective of this study is to investigate the impact of professional teeth cleaning and the substances used in modern dentistry for whitening on the microelement composition of tooth enamel. Materials and methods: To study the morphology and microelement composition of the enamel, scanning electron microscopy was performed using the MiraLM microscope equipped with a Schottky field emission electron gun from Tescan. Results: A comparative analysis between the areas subjected to mechanical cleaning and those where it was not applied revealed a significant difference in the research results, particularly in carbon, which changed from 25.16±1.04 to 32.02±1.8. An analysis of the enamel’s chemical composition before and after whitening revealed a decrease in carbon from 45.91±1.20 to 42.46±1.74. The change in phosphorus content was determined to be from 9.77±0.39 to 9.56±0.75. A decrease in calcium from 15.96±0.64 to 15.21±1.22 and magnesium from 0.07±0.01 to 0.01±0.01 was also observed. Conclusions: Professional dental hygiene does not have a direct impact on the microelement composition of enamel, such as the levels of calcium, phosphorus, fluoride, and other microelements. However, it can have an indirect and temporary influence due to the use of abrasive materials that affect dental deposits, pellicle, and the surface layer of enamel. Teeth whitening can affect the microelement composition of enamel, but these changes are mostly temporary and associated with processes of demineralization/remineralization and oxygenation.Документ Efficiency of local therapy with the use of a new preparation for oral care at periodontitis in the course of hyperpeptic gastritis after tobacco smoke intoxication(Aluna, 2018) Zolotukhina, O. L.; Romanova, I. G.; Gerasimova, I. V.; Kravchenko, L. S.; Tkachenko, I.

Monitoring and assessing the quality of their acquisition, that is, the organization of feedback as a means of managing the educational process, is a topical issue of educational services of higher educational institutions. For this purpose, the team of teachers of the chair of Propaedeutics of therapeutic dentistry Ukrainian Medical Stomatological Academy developed a methodical scenario of the professional competition “Lege artis”, which aims to developing and consolidating theoretical knowledge from the content module “Сlinical features of the teeth structure, tissues and organs of the oral cavity” and the mastery and improvement of manual skills in modeling teeth of different groups. The educational goal of the competition is to establish the priority of professional skills and theoretical training for a future specialist – a dentist who is able to provide the full range of medical services at the highest level. The competition is held in 2 rounds. First round is a tooth design that will be determined by drawing lots. The assessment of the quality of teeth modeling is performed on the following parameters: form of crown; ratio of sizes of crown/root; number, position, form of chewing cusps; form, depth of fissure, presence of a blind pit, additional cusp; number, position, form of the roots, apical foramens; expressed signs of crown curvature; expressed signs of the crown angle; expressed signs of deviation of roots; expressed signs of contact surfaces. As a result of the competition, 7-10 participants with the best points will pass in the second round. In the 2nd round the participants will answer 20 questions. The sum of points for the 1st and 2nd rounds will determine 3 winners. Conclusions. Improving teeth modeling techniques has great educational capabilities, contributes to the development of a sense of form, rhythm, the ratio of part and whole, educates accuracy, patience, perseverance. The work on modeling the tooth, on the one hand, facilitates the ability to use the acquired theoretical knowledge “in practice”, on the other hand it is nourished by questions that arise in the process of practical work. In the future, the art of dental modeling will be transferred to the clinic of therapeutic dentistry during restoration work.Документ Prognostic indices of pathological tooth wear development(Aluna Publishing, 2020-07) Pavlenko, S. A.; Pavlenkova, E. V.; Tkachenko, I. M.; Sidorova, A. I.; Korol, D. M.; Павленко, Світлана Анатоліївна; Павленкова, Олена Вікторівна; Ткаченко, Ірина Михайлівна; Сидорова, Алла Іванівна; Король, Дмитро МихайловичThe aim: To study possibilities of prognosis of pathological wear of tooth hard tissues development depending on the functional activity of masticatory muscles. Materials and methods: In order to achieve the goal of the study, a survey of patients at the age of 19 to 69 years was conducted for precision of number of persons who have increased tooth wear. During the examination of all patients, three groups were selected: control and two researched ones. Patients in the control group (30 patients between the age of 18 and 60 years old) had an intact dentition without any visible sign of increased tooth wear. The researched groups included 25 patients aged from 18 to 60 years old. The second research group included patients who had increased tooth wear of I-III level. The children of the patients of the II group with or without any sign of increased tooth wear were referred to the third research group. Results: The method of electromyography was performed for the study of peculiarities of the muscular activity of the maxillofacial area of the patients of the control and research groups. In our opinion, all manifestations of increased tooth wear are related to changes in the muscle system, the motor apparatus and the nervous activity of an organism. Conclusions: The study of direct muscular apparatus and related bone system may predict the possibility of developing of an increased tooth wear of young patients in the future and prevent its development, as well as to justify the application of a prevention and treatment plan of the studied pathology.Документ Reasoning of adhesive system choice for treatment of patients with increased tooth wear(Polskie Towarzystwo Lekarskie, 2018) Ткаченко, Ірина Михайлівна; Коваленко, Віктор Вікторович; Скрипников, Петро Миколайович; Водоріз, Ярослав Юрійович; Tkachenko, I. M.; Kovalenko, V. V.; Skrypnikov, P. M.; Vodoriz, Y. Y.Introduction: Perceiving the high prevalence of direct composite restoration technique usage for the rehabilitation of patients with increased tooth wear, as well as during the sanitation of oral cavity before indirect methods of rehabilitation, there is a necessity in more detailed reasoning of adhesive system application for treatment of dentition with increased tooth wear. The aim: The purpose of our work was to study the microstructure and chemical compound of hard tissues of teeth on background of increased tooth wear with the presence of a carious process with the application of adhesive systems of 5th and 7th generation. Materials and methods: The researche of teeth with physiological and increased tooth wear with the presence of carious process in the amount of 40 pcs. was carried out with the help of a raster electron microscope (SEM) Mira 3 LMU (Tescan, Czech Republic) with a maximum resolution of 1 nm and a maximum increase of 1 000 000. Elemental composition of the local area was determined using the X-max 80mm2 energy dissipation spectrometer ( Oxford Instruments, UK), integrated into a raster electron microscope. Results: The number of enamel prisms per square area in the case of increased tooth wear is 19 per 100 microns on average and 22.65 per 100 microns in carious teeth. Conclusions: Greater permeability is observed in the adhesive system of 7th generation (Adper Easy One), which allows it to be recommended for usege in the cases of severe caries and increased tooth wear.Документ Review of treatment methods of patients with uncomplicated teeth fractures(Polskie Towarzystwo Lekarskie, 2018) Vodoriz, Y. Y.; Marchenko, I. Y.; Shundryk, M. A.; Tkachenko, I. M.; Водоріз, Ярослав Юрійович; Марченко, Ірина Ярославівна; Шундрик, Марина Аркадіївна; Ткаченко, Ірина МихайлівнаIntroduction: Taking into consideration the high prevalence of dental trauma, the issue dental trauma management in the frontal dentition is relevant, considering the principles of biological, economical feasibility and clinical features of each case. The aim: The purpose of this review article is to draw dentists’ attention to the high prevalence of uncomplicated fractures of teeth (without pulp chamber exposure) and to highlight the most effective methods for their managment. Materials and methods:We have processed about 50 scientific sources devoted to the treatment of traumatic lesions of teeth. Among them are articles, scientific researches, clinical cases, laboratory researches. Conclusions: The most appropriate method for teeth restoration in a case of uncomplicated fracture is to preserve the fragment of the tooth with its further reattachment applying an adhesion protocol with the preliminary preparation of hard tissues of teeth. To achieve the best aesthetic results and increase the endurance of restoration it is expedient to cover the repartitioned fragment of a tooth with ceramic veneers.
