Magister Scientiae Dentium - MSc(Dent) (Orthodontics) / Orthodontic treatment has the ability to improve the aesthetics and the function of patients. In order to create space, orthodontic treatment often requires removal of teeth. The most common teeth removed for orthodontic treatment are the premolars. It has become popular to remove second premolars in certain cases where the soft tissue profile should not be altered. The Damon self-ligating orthodontic system is renowned for not requiring dental extractions in the majority of cases. The effect of extractions on the soft tissue profile of patients, in conjunction with using the Damon system, has therefore not been researched. It is important to understand the effect that orthodontic treatment and extractions can have on the soft tissue profile of patients. This effect can accurately be determined by making use of the soft tissue cephalometric analysis, developed by Dr Reed A. Holdaway in 1983.

Introduction Cette recherche constitue une étude clinique descriptive, visant à évaluer la douleur durant le traitement orthodontique avec boîtiers auto-ligaturants passifs et actifs. Matériel et méthode L'étude a été effectuée chez 39 patients (18 garçons, 21 filles), âge moyen 14 (entre 11 et 19 ans). Deux types de boîtiers auto-ligaturants ont été utilisés (SPEED n=20 et Damon n=19). Pour évaluer la douleur, un questionnaire a été élaboré par l'équipe de recherche. L’étude comportait 4 phases, c’est-à-dire l’évaluation de la douleur suite à l’insertion des 4 premiers fils orthodontiques du traitement de chaque patient (0.016 Supercable, 016 CuNiTi, 016X022 CuNiTi, 019X025 CuNiTi). Le même questionnaire était utilisé lors de chaque phase et le questionnaire comprenait 6 différents temps (T0: avant l’insertion du fil orthodontique, T1: immédiatement suite à l’insertion du fil, T2: 5h après l’insertion, T3: 24h après l’insertion, T4: 3 jours après l’insertion, T5: une semaine après l’insertion, T6: 4 semaines après l’insertion) suite à l’insertion de chaque fil. L’échelle visuelle analogue (EVA) et la version courte du questionnaire de Saint-Antoine ont été utilisés afin d’évaluer la douleur. Les données des EVA entre les groupes ont été comparées en utilisant le U test Mann-Whitney. Résultats et discussion Pour les deux premiers fils et pour tous les temps étudiés, il n’y avait pas de différence statistiquement significative entre les deux groupes (SPEED et Damon). Cependant, au moment de l’insertion (T0) du troisième fil (016X022 CuNiTi), parmi les patients ayant rapporté de la douleur (SPEED 47.1%, Damon 55.6%), le groupe Damon a rapporté une douleur significativement plus élevée que le groupe SPEED (p=0.018), (EVA moyenne SPEED=14.14±8.55, Damon=33.85±19.64). Trois jours après l’insertion du troisième fil, toujours parmi les patients ayant rapporté de la douleur (SPEED 23.5%, Damon 33.4%), la douleur était significativement plus élevée chez le groupe Damon que chez le groupe SPEED (p=0.008), (EVA moyenne SPEED=8.74±4.87, Damon=25.15±9.69). La plupart des analgésiques ont été pris suite à la pose du premier fil au temps T2 (5h) et T3 (24h). Il n’y avait pas de différence statistiquement significative entre les groupes en ce qui a trait au nombre de patients qui prenaient des analgésiques. La douleur n’a pas affecté le style de vie pour la grande majorité des patients. Les mots descriptifs sensoriels « tiraillement », « étau » et « élancement » et le mot affectif « énervant » étaient le plus souvent utilisés. Conclusion Les patients du groupe Damon ont ressenti significativement plus de douleur que les patients du groupe SPEED à l’insertion du troisième fil et trois jours suite à l’insertion. Plus de patients ont pris des médicaments pour la douleur avec le premier fil et le style de vie n’était pas affecté pour une majorité de patients. « Tiraillement », « étau », « élancement » et « énervant » étaient les mots descriptifs les plus utilisés par les patients pour décrire leur douleur. / Introduction This research is a descriptive clinical study designed to assess pain during orthodontic treatment with self-ligating brackets. Materials and methods This study was comprised of 39 patients (18 male, 21 female), mean age of 14 (range 11 to 19 yo). Two types of self-ligating brackets (SPEED n=20 and Damon n=19) were used. Pain was evaluated with a questionnaire developed by the research team. The study was divided into 4 phases. Pain was evaluated for 4 weeks following the insertion of the first 4 orthodontic wires for each patient (0.016 Supercable, 016 CuNiTi, 016X022 CuNiTi, 019X025 CuNiTi). The same questionnaire was used during each phase and included 6 different time-points following the insertion of each wire (T0: before insertion of orthodontic wire, T1: immediately after the insertion of the wire, T2: 5h after insertion, T3: 24h after insertion, T4: 3 days after insertion, T5: 1 week after insertion, T6: 4 weeks after insertion). The visual analogue scale (VAS) and the short version of Saint-Antoine’s questionnaire were used to evaluate the pain. VAS ratings between groups were compared using the Mann-Whitney U test. Results and Discussion For the first two wires and for all the different time points, there was no statistical difference between both groups (SPEED and Damon). However, at the insertion (T0) of the third wire (016X022 CuNiTi), among patients that reported pain (SPEED 47.1%, Damon 55.6%), Damon caused statistically significantly more pain than SPEED (p=0.018), (VAS mean SPEED=14.14±8.55, Damon=33.85±19.64). Three days after the insertion (T4) of the third wire, among the patients that reported pain (SPEED 23.5%, Damon 33.4%), the pain was statistically significantly higher with Damon than SPEED (p=0.008), (VAS mean SPEED=8.74±4.87, Damon=25.15±9.69). The most frequent use of pain medication occured with the first wire, at time-points T2 (5h) and T3 (24h). There was no statistical difference among the groups in terms of the number of patients taking medication. For the large majority of patients, the pain did not affect their life-style. The most frequently used sensorial words used by the patients to describe their pain were « pulling » (tiraillement), « cramping » (étau), « throbbing» (élancement). The most frequently used affective word was « annoying » (énervant). Conclusion The perception of pain for patients with Damon brackets was significantly higher than for those with the SPEED brackets at the insertion of the third wire and three days after placement of the third wire. More patients took pain médication with the first wire and the majority of patients did not report a change in their quality of life. « Pulling » (tiraillement), « cramping » (étau), « throbbing» (élancement) and « annoying » (énervant) were the words most frequently used by the patients to describe their pain.

Thesis (MA)--University of Stellenbosch, 2005. / Bibliography. Also available via the Internet.

Butterfly family Lycaenidae is cosmopolitan. Some species of the family are common in the Czech Republic, but some are at the risk of extinction, which is caused either by lack of habitat or host plant deficiency. Among the most endangered species in the Czech Republic are the damon blue (Polyommatus damon (Denis a Schiffermüller, 1775)) and the turquoise blue (Polyommatus dorylas (Denis a Schiffermüller, 1775)). This thesis aims to review the biology of both species, causes of threat and possibilities of their practical conservation, and to describe genetic variability of Czech populations of two critically endangered Lycenids, the damon blue and the turquoise blue, and to compare them with European populations for potential import of alien individuals to Czech populations. Genetic assignment is important for possible reintroduction or revitalization of Czech populations from foreign sources. I detected in this thesis that the damon blue has more genetic variability than the turquoise blue and this pattern is not only geographical. I assume that Czech populations of both species experienced bottleneck and are under genetic drift. Furthermore, the Central European individuals genetically differ from Southern European and Baltic samples, and the number of haplotypes is high in Central Europe. The current distribution is not caused by colonization after the last glacial period. According to the results, it is appropriate to protect all current populations separately, rather than supplement them from other sources, because they can be genetically different. Finally, I discuss the management planned for the two species in the Czech Republic and connect it to my results.

Thesis (MA (English))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This thesis explores masculinity and sexuality, hegemonic and “deviant” in the nation state of the old apartheid South Africa, by addressing aspects of fatherhood, boyhood and motherhood in white, predominantly Afrikaans family narratives. In doing this, I explore the ways in which the young boys in texts such as The Smell of Apples (1995), by Mark Behr, and moffie (2006), by André Carl van der Merwe, are systematically groomed to become the ideal stereotype of masculinity at the time: rugged, intelligent, successful and heterosexual. The main focus of this thesis is to explore the ideologies inherent in constructing the white, Afrikaner man, his woman and their family. This will be done with specific reference to the time frame between the early 1970s to the fall of the apartheid regime in the early 1990s, focussing on the young white boys who are sent to do military training and oftentimes, a stint on the border between Angola and the then South-West Africa, in order to keep the so-called threat of communism at bay. I explore what happens when this white-centred patriarchal hegemony is broken down, threatened or resisted when “deviance” in the form of homosexuality occurs. A second focus of this thesis is that of “deviance” in the army. I analyse “deviance” in three novels, moffie (2006) by André Carl van der Merwe, The Beautiful Screaming of Pigs (1991) by Damon Galgut and Kings of the Water (2009) by Mark Behr. These novels foreground “deviance” and I make use of them in exploring the punishment, or “consequences” of being homosexual or “deviant” in the highly masculine environs of the South African National Defence Force (SANDF) army. I also examine the muted yet, I argue, resistant voices of female characters in these novels. This thesis concludes by briefly noting the aftermath of this war, the after-effects of a white, hegemonic, conservative ruling party at the helm of a divided, war-faring country on its soldiers, who are now middle-aged men. / AFRIKAANSE OPSOMMING: Hierdie tesis ondersoek manlikheid en seksualiteit, hegemonie en “afwykings” in die staat van ou apartheid Suid-Afrika deur te verwys na aspekte van vaderskap, seunwees en moederskap in blanke, oorwegend Afrikaanse gesinsvertellings. Eerstens sal daar ondersoek ingestel word na die wyses waarop jong seuns in tekste soos The Smell of Apples (1995) deur Mark Behr en moffie (2006) deur André Carl van der Merwe stelselmatig gekweek word tot die ideale stereotipe van manlikheid in die era: ongetem, intelligent, suksesvol en heteroseksueel. Die hoofklem van hierdie tesis is om die denkwyses onderliggend aan die konstruksie van die blanke Afrikaner man, sy vrou en hulle gesin, te verken. Dit sal bewerkstellig word deur na die tydperk vanaf die vroeë 1970s tot en met die ondergang van die apartheidsbewind in die vroeë 1990s te verwys, met spesifieke klem op jeugdige blanke seuns wat gestuur is vir militêre opleiding en dikwels ook diensplig aan die grens tussen Angola en destydse Suid-Wes Afrika om die oënskynlike kommunistiese aanslag af te weer. Daar word verken wat plaasvind wanneer hierdie blank-gesentreerde, patriargale oorwig afgebreek, bedreig of teengestaan word deur “afwykings” soos die voorkoms van homoseksualiteit. ‘n Tweede fokuspunt van hierdie tesis is die “afwykings” in die weermag. Die volgende drie “afwykingsromans” word ontleed: moffie (2006), The Beautiful Screaming of Pigs (1991) deur Damon Galgut en Kings of the Water (2009) deur Mark Behr. Hierdie romans ondervang die idee van “afwykings” en word gebruik in die ondersoek na die straf of gevolge van homoseksueel of “afwykend” wees in die uitsluitlik manlike omgewing geskep deur die SANW-opleiding. Daar word ook ondersoek ingestel na die stilgemaakte; dog, soos aangetoon word, versettende stemme van vroulike karakters in die romans. Hierdie tesis sluit af deur vlugtig te verwys na die nasleep van die oorlog en die gevolge van ’n blanke, heersende, konserwatiewe party aan die stuur van ’n verdeelde, oorlogvoerende land op sy soldate wat tans middeljarige mans is.

Thesis (MA (English Literature))--University of Stellenbosch, 2005. / In this thesis I examine the presentations of masculinity in several novels published in the post-apartheid period in South Africa, that is, the period after 1994. The novels under discussion are all male-authored texts and include novels by J M Coetzee (1999), André Brink (2000), Phaswane Mpe (2001), K Sello Duiker (2001), Zakes Mda (2002) and Damon Galgut (2003). In the introduction theoretical issues regarding masculinity are discussed on the basis of Morrell (2001) and a broad framework for the thesis is outlined. Subsequently the presentation of masculinity is analysed in each of the respective novels under discussion. Issues such as a definition of masculinity (or rather, masculinities), the interaction between men as friends, as colleagues; as well as issues such as heterosexuality and homosexuality are discussed. What perspectives does the author provide on masculinity? How do the male characters experience the new South Africa? What is the nature of their interaction with the female characters in the novels? Another aspect dealt with is the repression of homosexual desire for another man and the way in which it is suppressed beneath a macho façade. In the conclusion the different perspectives are compared and similarities and differences are briefly pointed out. In the end, an important question that comes to mind is: Do these men present a different type of masculinity emerging in the period after liberation, or do they merely (as depicted by their authors) perpetuate the patriarchal masculinities associated with the period before 1994?
