Motifs on Bohemian and Central European enameled glass. From the second half of the 16th century until the the beginning of 18th century
Černovská, Jana ; Nespěšná Hamsíková, Magdaléna (advisor) ; Schöttner, Jan (referee)
Motifs on Bohemian and Central European enameled glass. From the second half of the 16th century until the the beginning of 18th century. This Bachelor's thesis attempts to map out a broad range of motifs painted on glass using enamel within the Bohemian and Central European milieu in the period from the mid 16th until the early 18th century. Specific attention is paid to large cylindrical goblets, the so-called Humpens. By means of concrete examples from significant Czech and foreign collections - including items intended for representative purposes as well as objects commonly used by the middle class - individual motifs or groups of motifs are identified. The thesis aims to define the function assigned to these vessels depending on the decorative theme used. The author also focuses on ornamental motifs featured on painted glass that were frequently engraved using a diamond point. To make them, painters and engravers drew their inspiration from period prints and prints from the preceding era. For this reason, these original prints are studied as well, and subsequently compared to the specific motifs used on the glass.

The intake of food organic acids and the influence on hard dental tissues
Procházková, Nikola ; Krugová, Alena (advisor) ; Zavřel, Viktor (referee)
This bachelor thesis deals with the influence of organic acids on hard dental tissue. The theoretical part is focused on the construction of tooth-enamel, dentin and cement and, of course, to individual organic acids. Furthermore, the disease-dental erosion caused by acids is theoretically described. The practical part consists of evaluated questionnaires. Questions in the questionnaire are formulated to respond to the goals I have set out. The questionnaire was in two forms. The first form was electrocnic and was placed on the Internet. 65 respondents answered this questionnaire. The second form was printed and was placed in the waiting room of the dental clinic in Černý most. The total number of respondents was 102. After evaluating the questionnaire survey, I identified the risk of erosion. The questionnaire survey should also reveal the subjective feeling of patients after ingestion of organic acids.

Věra Janoušková - "I sew the enamel sculptures like the scenes made from tatters" (textile collages and enamel sculptures)
Čejková, Markéta ; Klimešová, Marie (advisor) ; Lahoda, Vojtěch (referee)
ASTRACT: The thesis deals with textile collages and enamel sculptures and their mutual relation of a Czech sculptor Vera Janouskova, which have been made since forties till the first decade of 21th century. The first chapter focuses on biographical data and memories of Vera Janouskova, primarily aimed to facts important for the works in textile collages and enamel sculptures. The second chapter focuses on textile collages and begins with Roger Bissiere collages which inspired Vera Janouskova, continues with a detailed description of her three most known textile collages and presents a minor, not yet published textile collage hanging in Vera Janouskova studio. This chapter also analyses the terminology used for textile collages and tapistry. The third chapter, which is the most wide, deals with enamel sculptures. It begins with their categorisation based on their timing and topics they cover. Individual decades are initiated with a short information on the time period the groups of enamel sculptures were made in. Selected enamel sculptures are described in detail. Prior to the detailed analysis of the groups of enamel sculptures there are subchapters dedicated to the relation of Vera Janouskova enamel sculptures to the artistic scene in Europe, USA and also in Czechoslovakia. The works of several artists...

PLENARY OF HANUŠ II. Z KOLOWRAT FROM ST.VITUS TREASURY
Stránská, Kateřina ; Sojka, Jaroslav (advisor) ; Šmied, Miroslav (referee)
The bachelor thesis called Plenář Hanuše II. z Kolowrat z chrámového pokladu svatovítského, is dealing with one of the leading liturgical objects from a time of Jiří z Poděbrad. Although St. Vitus temple treasure has adequate art-historical attention, this late-gothic relics panel eluded independent processing. Given the interest of student in the history of decorative arts and earlier studies at the School of Applied Arts in Turnov, is selected topic, where there can be demonstrated ability to connect classical art-historical perspective with practical insight, thoroughly dedicated to the art-craft techniques. Clearly sorted chapters, in which a person approaches the donor, his ancestry, accurate description of the object and history of its repairs, modifications and restoration, results in synthetic view which brings new information. Reliquary plate is not perceived only as a cold artistic creation, but especially as still alive liturgical object with reference to various relics and theological timeless meaning of oblation in the Middle Ages. The aim is, among other things, to get closer to the culture and donor activity of late-gothic Bohemia.

Long-term durability of composite restoration margins in environments with increased corrosion risk
Roubíčková, Adéla ; Bradna, Pavel (advisor) ; Veverka, Jan (referee) ; Halačková, Zdena (referee)
Introduction: An adhesive bond between hard dental tissues and composite reconstructions is exposed to mechanical load, water, bacteria, enzymes and different chemical compounds. These factors could impair durability and resistance of composite reconstructions. In contrast with extensive research of negative influence of water on degradation of adhesive bonds, the influence of chemical substances on adhesive bond has not been investigated to a greater extent. Aim: The aim of the experimental part of the thesis was to evaluate the influence of hydrogen peroxide containing tooth-whitening products and mouth rinses containing chlorhexidine and fluoride on a long-term stability of class V composite restorations created using four contemporary adhesive systems by a microleakage method. Materials and methods: The following adhesive systems were investigated: total-etch Gluma Comfort Bond (GLU), and self-etch adhesives Clearfil SE Bond (CLF), Adper Prompt (ADP) and iBond (IBO). Standardized class V cavities were prepared in 192 extracted human teeth (one cervical margin in the cementum and one in the enamel). Subsequently, the cavities were restored using microhybride composite Charisma. The specimens were then exposed to the tooth whitening system Opalescence PF 20, mouth rinse Corsodyl containing...

Effect of corrosion environment on the long-term stability of composite material to enamel and dentin bonds
Dudek, Michal ; Bradna, Pavel (advisor) ; Veverka, Jan (referee) ; Halačková, Zdena (referee)
Introduction: Adhesive technology represents a significant advancement among different treatment options of dental caries. Its advantages involve not only highly aesthetic reconstructions, but also ability to preserve hard dental tissues compared to more traditional filling materials such as amalgam, where the material retention was achieved through undercuts. A potential of adhesive technology to arrest progression of an incipient caries has triggered its wider use in dental caries management, potentiated by an ongoing development of new adhesive systems and composite materials that assure an acceptable long-term stability of adhesive reconstructions. Adhesive bonds of dental reconstructions are in the oral cavity constantly challenged by various mechanical, chemical and biological factors. One of the chemical agents with detrimental potential is peroxide bleaching gel used for teeth brightening. Currently bleaching belongs to the most frequent cosmetic dental procedures. The active ingredient of bleaching gels is hydrogen peroxide or its precursors. It is assumed that free oxygen radicals released from peroxides attack double bonds of chromophore molecules captured within the tooth tissues. Because of the high reactivity and nonspecific nature of these oxygen radicals, they may affect also dental...
