The role of the radiographer in stomatology
STEINEROVÁ, Karolína
This bachelor's thesis focuses on radiological imaging methods and their use in dentistry. Radiological devices have been developing rapidly recently and have become a common part of dental outmous clinics. They are used not only in the field of dental and surgical dentistry, but also in aesthetic dental treatments. The thesis is divided into theoretical and practical parts. The aim is to map the advantages and disadvantages of each type of device and theri suitability of their use in dentistry. The theoretical part deals with basic anatomical concepts of the orofacial field, an overview of radiological diagnostic devices, their use in the field of dentistry and specially aesthetic dentistry, and the associated radiation protection of workers and patients. Furthermore, it focuses on the basic aesthetic anomalies of the teeth and their treatment, which usually precedes the imaging of the target area. The second part of the thesis was compiled on the basis of a questionnaire survey conducted. Two questionnaires were created concerning the use of imaging methods in the aesthetic repair of teeth, the equipment of dental workplaces and access to patients from the point of view of imaging and radiation protection from the point of view of patients and dentists. The aim was to answer research questions about the use of radiology in aesthetic dentistry and the level of information patients receive about their radiological examinations. According to research, the largest representation is the intraoral type of imaging, namely bitewing image, which is suitable for basic diagnosis of dental anomalies as well as changes in the structure of the tooth. This method is easy, fast and practically without any extra burden put on the patient. The most commonly performed aesthetic procedure turned out to be treatment with orthodontic apparatus, in which imaging of the original position of the teeth is necessary. The least used method in the field of dentistry is magnetic resonance imaging, due to the availability and creation of artifacts in images from dental metal fillings. Research shows that patients are not properly informed about the course, necessity or consequences of radiological examination. Although the dose of ionizing radiation is negligible in dental imaging examinations, the doctor should prevent and inform the patient of the patient's concerns. More than half of respondents consider X-rays to be health-burdensome.

The analysis of teleradiographs of adult face subjects
Štubňová, Mária ; Eliášová, Hana (advisor) ; Velemínská, Jana (referee)
Analysis of teleradiographs has become widely used as a diagnostic and analytic tool in clinical orthodontics. It is based on exact entered landmarks of soft tissues and skeletal. There was 82 teleradiographs analyzed in this diploma thesis and from this group were 28 men and 54 women. The teleradiographs were measured with program Dolphin Imaging. Afterwards the group of patients was split into groups based on gender and dental classes. The obtained data were analyzed by the help of Steiner analysis and consequently statistically tested. Measured values for each dimension were then compared between the dental classes and surveyed also for differences between genders. These tests were due to non-parametric data distribution done by Kruskal - Walis test. Consequently were the measured data and surveyed differences compared with available publication on the topic.

Change of Cephalometric Values Focused on Labial Bone Thickness
Filipová, Diana ; Dostálová, Taťjana (advisor) ; Racek, Jaroslav (referee) ; Špidlen, Miloš (referee)
The morphology of the craniofacial complex is prone to alterations resulting from a wide range of external factors. In the first part of the presented thesis, we analysed the influence of slow long- term changes of the environment and population genome by comparing historical (11-12th century AD) and contemporary skulls using cephalometric X-ray images. The second part focuses on the effects of orthodontic treatment on bone thickness in relevant areas, with the analysis being based on Cone Beam computed tomography. A comparison of the palatal angle of 115 historical and 75 contemporary skulls revealed a statistically significant decrease of this parameter. The follow-up of 58 patients utilizing three- dimensional diagnostic imaging measurements before and after treatment revealed a statistically significant decrease in vestibular bone thickness, without changes of total alveolar width. Our analysis revealed a substantial bone response to respective forces, with relevant clinical implications - respecting the anatomical limits of the range of motion is essential to achieve therapeutic success and to avoid alveolar defects. Keywords: 3D imaging, CBCT, cephalometry, orthodontics, dentistry
