RESUMEN

THE STUDY OBJECTIVE: Was to give a comparative assessment of the movement of enamel and dentin fluid depending on the morphological structure of different sections of human dental hard tissues. MATERIALS AND METHODS: The research involved 140 female subjects aged 21-30 years. Sizes, form, surface of enamel-dentin junction, enamel prisms and their crystals in superficial, middle and deep sections, width, tortuosity, facing of dentin tubules of tested teeth were analyzed by scanning electron microscope Jeol JCM-5700 and atomic force microscope NTEGRA Prima. The biochemical study examined the quantitative content of water in the samples of enamel, dentin, enamel-dentin junction by weighing sample weights before and after drying. The data obtained were processed by methods of variation statistics using standard packages Microsoft Excel 2008, Statistica 12.0. RESULTS: The enamel-dentine junction of large-fastened type is characterized by zones of dentin integration into enamel at the distance of more than 10 mm, with regular arrangement of enamel prisms and wide dentine tubules of 3.55 to 4.70 µm in diameter; no water content reduction was found. The small-fastened type has less pronounced spots of dentin interference with enamel from 2 to 10 µm, the dentinal tubules are slightly curved with a diameter of 2.90 to 3.60 µm, the water content in dentin is reduced. In microfastened type, a linear structure with interpenetration zones up to 2 µm, enamel prisms slightly ordered, dentin tubules narrowed and curved in diameter from 1.30 to 1.95 µm, water content in enamel and dentin is reduced. CONCLUSION: At microfastened type of enamel-dentin junction, chaotic arrangement of enamel prisms and narrow dentin tubules water movement is broken and metabolic processes are reduced that determines high probability of exposure of dental hard tissue diseases.

RESUMEN

OBJECTIVE: The aim of the study is to evaluation of the quality of orthodontic treatment by comparing the severity of signs of distal occlusion before the start of orthodontic treatment and after its completion. MATERIAL AND METHODS: Quantitative assessment of the severity of distal occlusion in 83 patients aged 17 to 30 years before and after orthodontic treatment. Depending on the chosen treatment algorithms, the patients were divided into 3 groups. The first group - 34 people - treatment included the use of a functional non-removable orthodontic device (FNT). The second group - 21 people - the treatment was accompanied by the removal of individual teeth of the upper jaw and the retraction of a group of front teeth of the upper jaw. Patients of the 3rd group - 28 people - underwent combined orthodonto-surgical treatment. The severity of distal occlusion was assessed using 3D cephalometric analysis data. To obtain a subjective assessment of the quality of orthodontic treatment, patients were asked to fill out questionnaires before and after orthodontic treatment. RESULTS: The severity of distal occlusion decreased as much as possible as a result of treatment of the first group in 23.07% of patients and the third group (16.63%), which is interpreted by the formulation «significant improvement¼ of the dental anomaly. Patients of the first and third groups had a high degree of satisfaction with the result of treatment, according to the quantitative assessment of the questionnaire. The severity of distal occlusion in the second group was reduced to a lesser extent (55.5%), compared with the first and third groups, which is interpreted as «moderately improved¼. Patients noted an average degree of satisfaction with the result of treatment, as the implemented treatment plan did not meet their expectations in the aesthetic aspect. CONCLUSION: The use of FNT for the extension and normalization of the position of the lower jaw is justified in the case of refusal of patients from combined orthodonto-surgical treatment, as it allows to fully solve the functional, aesthetic and psychological problems of patients, which contributes to improving their quality of life.

RESUMEN

OBJECTIVE: Studying the issue of quality control and safety of medical activities. MATERIAL AND METHODS: The analysis of domestic literature on the quality of filling out medical documentation has been carried out. RESULTS: A dental patient's medical record (ICSD) is not only the most important legal document, but also a certain indicator of the level of professional competence of a dentist. To find out all sorts of reasons that led to professional errors and adverse consequences after the provision of dental care, a thorough study and general analysis of medical documentation is of great importance, the maintenance and correct execution of which is also necessary for solving a number of other, including legal issues. The most common drawbacks in the design of a dental patient's medical record have been identified, which indicates a decrease in the quality of medical care provided to patients. CONCLUSION: At the moment, there are still unresolved issues related to complete completion of medical documentation. When analyzing the literature, we did not find a purposeful study of the medical history of a dental patient during surgical treatment, which requires further research.

RESUMEN

OBJECTIVE: The purpose of this investigation was to explore the quality of 38, 48 teeth's hard tissues at different eruption stages and mandibular bone in different postpartum ontogenesis periods. MATERIAL AND METHODS: The research involved 102 male patients divided into groups according to their age: 15-20, 21-30 years old, they were extracted one tooth 38, 48 without inflammatory process signs and a fragment of the mandibular bone alveolar part in the projection of the teeth 38, 48 for orthodontic indications. In the comparison group (49 observations without signs of connective tissue dysplasia), in the study group (53 observations with signs of connective tissue dysplasia) we extracted teeth 38, 48 which were in the bone tissue. We analyzed condition of crown and root systems of extracted 38, 48 teeth, densitometric density of mineral component, size of enamel prisms, size of prismatic shells of organic matrix, spatial organization of collagen fibers in bone tissue, size characteristics of bone plates and mineralization centers of bone tissue. Processing of the obtained data was performed by methods of variation statistics using standard packages Microsoft Excel 2008, Statistica 12.0. RESULTS: The paper reveals one of the surgical dentistry pressing issues related to the tething mechanism of lower human wisdom teeth, considered by the authors from the position of tissue disorders in collagen type 1 observed in connective tissue dysplasia. At age of 15-20 years in connective tissue dysplasia, the enamel prisms hypomineralized areas are generalized; at age of 21-30 years the hypomineralized areas are characterized by local changes. At the age of 15-20 years in connective tissue dysplasia the bone plates splitting is observed at the level of most fibrils, collagen fibers have insufficiently oriented direction in contrast to the age group of 21-30 years where bone plates splitting is characteristic for single fibrils and collagen fibrils are clearly oriented. CONCLUSION: Morphological and histological changes in teeth 38, 48 and in bone tissue prevent correct and timely teething at 15-20 years and create more favorable conditions for teething at 21-30 years with a slower rate in connective tissue dysplasia, but in both groups teeth eruption occurs under unfavorable anatomic conditions.

RESUMEN

OBJECTIVE: It is necessary to study the human enamel prisms size at different periods of postpartum ontogenesis by atomic force microscopy. MATERIAL AND METHODS: The study involved 94 males which were divided into groups by age: 15-20, 21-30, 31-40, 41-50, 51-60 years old, each examined male had one 3.8 or 4.8 tooth removed (from the fracture line in the region angle of the mandible, according to orthodontic indications) for medical reasons. The shape, roughness, length and width of the enamel prisms were studied in the Image Analysis NT-VDT program according to the method of Omsk State Medical University. RESULTS: The enamel prisms structure at all ages has a regular, ordered shape with 6-sided and 7-sided figures. The most constant structure occurs at the age group of 41-50, 51-60 years. The fastest enamel prisms growth occurs in the direction that increases the prism length at all ages. Growth on a plane which increases the prism width is slow at 41-50 years. It is catching up with the growth rate of enamel prisms in length at 51-60 years old. Enamel prisms at 15-20, 21-30 years old stretch faster in the horizontal direction. CONCLUSION: In maturation process, due to correct and harmonious growth, enamel prisms are timely modified from pyramidal form in the early postpartum period to a prismatic form in the late postpartum period of ontogenesis.

RESUMEN

OBJECTIVE: The purpose of the study is to investigate the existing normative legal documents governing the activities of doctors specializing in «dentistry¼, providing medical care in a multidisciplinary hospital. MATERIAL AND METHODS: The normative legal coverage of medical workers' activities on delivering dental care for adult population with infectious diseases in stationary conditions for a thirty-year period was analyzed. The research and information method and content analysis were used. RESULTS: The existing regulatory legal framework governing the activities of medical workers does not contain time standards for one patient who is on inpatient treatment to visit doctors specializing in «dentistry¼ in a multidisciplinary hospital, which does not correspond with modern requirements and does not allow determining the workload norms and standard numbers of these specialists. CONCLUSION: Despite the presented modern possibilities of introducing the latest technologies and intensifying the activities of doctors specializing in «dentistry¼ on an outpatient basis, the organization of medical care and the delivering of dental services in a hospital including to infectious patients require further improvement.

RESUMEN

OBJECTIVE: To give a quantitative and qualitative characteristic of the structure of the enamel's mineral component structure of impacted teeth with or without connective tissue dysplasia in different periods of early postnatal human ontogenesis using densitometry and atomic force microscopy. MATERIALS AND METHODS: The study involved 120 males with and without connective tissue dysplasia (CTD), which were divided into 3 equal subgroups (60 people with CTD and 60 people without CTD), 20 people in each, according to age: 15-20, 21-30, 31-40 years old. Each of the examined was removed either 3.8 or 4.8 tooth. To study the inorganic component of tooth enamel, a densitometric assessment of enamel's optical density was carried out using computed tomography in the Kodak Dental Systems software (Trophy 2000) and preparation of thin sections of tooth samples 3.8 or 4.8 for atomic force microscopy (AFM) according to the methods of Omsk State Medical University. RESULTS: The structure of tooth enamel in connective tissue dysplasia in the early postpartum period of ontogenesis is characterized by pronounced polymorphisms and an insufficient level of maturity. The ordering and orientation of the enamel prisms are disturbed due to insufficient packing density and a large distance between the enamel prisms at the age of 15-20, 21-30. The established changes indicate the incomplete nature of amelogenesis with connective tissue dysplasia at the indicated ages. CONCLUSIONS: In case of connective tissue dysplasia in the early postnatal period of ontogenesis, an incomplete amelogenesis is observed. This process is manifested by lower values of the mineral component's optical density, low packing of enamel prisms, a large distance between enamel prisms and their irregular shape.
