Holoubková, Lucie ; Koťová, Magdalena (advisor) ; Urbanová, Wanda (referee)
Aim: The aim of the bachelor thesis was to summarize the knowledge about orthodontics and dental caries in orthodontic patients. Furthermore, it observes the degree of deterioration of the biological factor of the dentition after 2 to 3 years of orthodontic treatment in the form of increased caries formation or newly made fillings. Introduction: With the placement of fixed orthodontic appliances, retention sites for plaque accumulation in the oral cavity increase. Its regular and correct removal is therefore an important factor both for the prevention of damage to the hard and soft tissues of the oral cavity and for the quality outcome of orthodontic therapy. We repeatedly observe that patients who are very well motivated and maintain adequate oral hygiene at the beginning of orthodontic treatment show a decline in motivation over time and the oral condition deteriorates. Patients in whom orthodontic treatment must be interrupted or discontinued due to caries or severe gingivitis are no exception. Methods: OPG images of orthodontic patients with an interval of 2 to 3 years were evaluated. The cohort consisted of 50 patients from the Department of Orthodontics and Cleft Defects of the Dental Clinic of the University Hospital Královské Vinohrady born between 2006 and 2012. Subsequently, all newly...

Čučková, Tereza ; Koťová, Magdalena (advisor) ; Urbanová, Wanda (referee)
This bachelor's thesis focuses on the issue of removable orthodontic appliances and aims to identify the most effective hygienic care technique for microorganisms' quantity reduction. Firstly, the thesis provided a summary of basic information about removable orthodontic appliances. Further, the autor defined on the physiological microflora of the oral cavity as one of the main sources of bacteria inhabiting the removable appliance and accordingly focused on this area. Moreover, the reader is introduced to appropriate techniques of removable orthodontic appliance care, such as machine tools, chemicals, and natural substances. Finally, the role of a dental hygienist is defined as the primary source of motivation and instructions regarding maintaining and retaining oral health. Within the practical part, the thesis focused on the identification of microorganisms' spectrum part colonizing the removable orthodontic appliance. The antimicrobial efficacy of natural extracts was subsequently examined with the use of identified microorganisms. Specifically, the impacts of Azadirachta indica, Cinnamomum Verum, and citric acid were explored. When tested by the disc diffusion method, only citric acid proved to directly impact the susceptibility of isolated bacteria. Therefore, this substance was identified as...
