Das Ziel dieser Arbeit war die Bestimmung der kleinsten relevanten Veränderung des wahrgenommenen Mundgesundheitszustandes, der Minimal Important Difference (MID), des Oral Health Impact Profile (OHIP). Die MID sollte für die deutsche Version des OHIP mit 49 Fragen (OHIP-G49), die deutsche Kurzversion mit 14 Fragen (OHIP-G14) sowie für die einzelnen Dimensionen der deutschen und englischen Version des OHIP bestimmt werden. Es handelt sich um eine klinische Fallserie mit 224 konsekutiv rekrutierten, prothe-tischen Patienten. Die mundgesundheitsbezogene Lebensqualität wurde mittels des OHIP- G49 an zwei Terminen vor der Behandlung (Basisuntersuchungen) sowie vier und sechs Wochen nach Behandlungsende (Nachkontrolluntersuchun-gen) bestimmt. Zu den Nachkontrolluntersuchungen schätzten die Patienten zu-sätzlich die Veränderung ihres Mundgesundheitszustandes gegenüber dem Zeit-punkt vor der Therapie anhand einer globalen Frage ein. Anhand der Ergebnisse der Basis- und Nachkontrolluntersuchungen wurde der Median der Differenzen der OHIP-Summenwerte errechnet. Dieser Wert entspricht der MID. Für die deutsche Version des OHIP mit 49 Fragen wurde ein Wert von 6,0 OHIP-Punkten ermittelt. Der Wert für den kurzen Fragebogen OHIP-G14 betrug 2,0 OHIP-Punkte. Für die Dimensionen der deutschen und englischen Sprachversion des OHIP konnten nur teilweise Ergebnisse gefunden werden. Das Studienergebnis lässt den Schluss zu, dass für beide untersuchten Versionen des OHIP ein klar definierter, minimal relevanter Unterschied (MID) der Summen-werte existiert. Die MID unterstützt die Interpretation der klinischen Bedeutung von Veränderungen des vom Patienten wahrgenommenen Mundgesundheitszustan-des. Sie stellt eine wichtige Größe zur Bewertung prothetischer Therapieeffekte dar.

O objetivo do presente estudo foi avaliar o efeito do tratamento periodontal na qualidade de vida de pacientes portadores de Síndrome Metabólica (SM), em uma amostra de 48 pacientes. Os pacientes apresentavam diagnóstico de Periodontite e SM e foram randomizados para dois grupos de tratamento: um grupo ao qual era oferecido tratamento periodontal imediato e outro grupo de tratamento tardio, que receberia o tratamento periodontal após seis meses da sua inclusão no estudo. Para aferir qualidade de vida relacionada à saúde bucal e qualidade de vida geral, foram usados os instrumentos OHIP-14 e WHOQoL-bref, respectivamente. Exames periodontais completos avaliaram Índice de placa visível, Índice de sangramento gengival, Fatores retentivos de placa, Profundidade de sondagem, Sangramento à sondagem e Nível de inserção clínica, em seis sítios por dente. Além disso, exames antropométricos, exames sorológicos e entrevistas com os questionários de qualidade de vida foram realizados no momento inicial e após seis meses do início do estudo. Os dois grupos se mostraram semelhantes no momento inicial. Após seis meses, foram observadas reduções significativas no grupo de tratamento imediato para todos os parâmetros periodontais clínicos. A análise do WHOQoL-bref por domínios mostrou pequenas alterações não significativas em ambos os grupos. Na avaliação dos escores totais de OHIP-14 foi observada, após 6 meses, uma redução de 18,6 para 15 (Δ=3,6) no grupo tardio e de 15 para 5,7 (Δ=9,3) no grupo imediato, com diferenças estatisticamente significantes entre os grupos (p=0,003). Essas diferenças resultaram em um tamanho de efeito de 0,27 (pequeno) para o grupo tardio e 0,78 (moderado) para o grupo imediato. Na análise por domínios, foram encontradas diferenças significativas para o grupo imediato nos domínios limitação funcional (p=0,006), desconforto psicológico (p=0,001), incapacidade física (p=0,009) e incapacidade psicológica (p=0,007), comparado ao grupo tardio. Em pacientes portadores da SM, as mudanças na percepção da qualidade de vida aferidas pelo OHIP-14 foram significativas para o grupo de pacientes que recebeu tratamento periodontal imediato, em comparação ao grupo que recebeu o tratamento tardio. / The aim of this study was to assess the effect of periodontal treatment in quality of life of patients with Metabolic Syndrome, in a sample of 48 patients. The patients showed diagnosis of Periodontitis and Metabolic Syndrome and were randomized for two treatment groups: 1) immediate periodontal treatment 2) later treatment, six months after study inclusion. The instruments OHIP-14 and WHOQoL-bref were used to assess oral health related quality of life and general quality of life, respectively. Complete periodontal exams evaluated plaque visible index, gingival bleeding index, plaque retentive factors, probing depth, bleeding on probing and clinical attachment level, on six sites per tooth. Furthermore, antropometrics, blood exams and interview with quality of life measures instruments were performed in baseline and six months after the beginning of the study. Both groups were similar in baseline. After six months, significant reductions on immediate treatment group for all clinical periodontal parameters were observed. The WHOQoL-bref analysis by domains showed no significant small changes, for both groups. After six months, a decrease of 18,6 to 15 (Δ=3,6) for the later treatment group and 15 to 5,7 (Δ=9,3) for the immediate treatment group was observed in the evaluation of OHIP-14 for total scores, with statistical significant differences between the groups (p=0,003). These differences resulted in an effect size of 0,27 (small) for the later treatment group and 0,78 (moderate) for the immediate treatment group. In domains analysis, significant differences for the immediate treatment group on functional limitation (p=0,006), psychological discomfort (p=0,001), physical incapacity (p=0,009) and psychological incapacity (p=0,007) domains, were found compared to later treatment group. In patients with Metabolic Syndrome, changes on quality of life perception measured by OHIP-14 were significant for immediate treatment group, compared to the later treatment group.

Previous studies suggest that simplified procedures for complete dentures (CD) construction achieve results similar to the traditional methods. The objective of this study was to compare the effectiveness of a traditional and a simplified protocol for construction of conventional complete dentures. Fifty patients were randomly allocated into two equal groups, traditional protocol (T group) and simplified protocol (S group). Treatment outcomes were assessed before the installation of the new prosthesis and 30 days after the last adjustment, including measurements of quality of life related to oral conditions measured by the Brazilian version of OHIP-Edent scale and patients’ satisfaction with the upper and lower dentures using a visual analogue scale (VAS), which combines the patient's perception in relation to overall satisfaction with the comfort, stability, ability to chew, ability to talk and aesthetics. The results showed an overall 33.3% reduction in negative impacts of oral conditions on quality of life (p<0.001) and improved satisfaction with the upper and lower dentures (p<0.01). Quality of life improvement occurred in all dimensions of the OHIP-Edent (p<0.001). Despite the significant reduction in quality of life impacts and significant increase in patients’ satisfaction with the dentures, there were no differences between the traditional and simplified protocols. It was concluded that the simplified protocol results in perception of treatment outcomes similar to the traditional protocol. / A confecção de próteses totais convencionais pode resultar em potenciais benefícios funcionais e estéticos ao paciente. Estudos prévios sugerem que procedimentos simplificados para confecção de próteses totais (PT) alcançam resultados semelhantes ao dos métodos tradicionais. O objetivo deste estudo foi, através de ensaio clinico randomizado controlado, comparar o impacto de um protocolo tradicional e um simplificado, para confecção de próteses totais convencionais. Foram confeccionadas PT convencionais, superior e inferior para 50 pacientes adultos e idosos, alocados aleatoriamente em dois grupos de igual número, Grupo T do protocolo tradicional e Grupo S do protocolo simplificado. Os seguintes desfechos foram avaliados antes da instalação das próteses e após 30 dias do último ajuste feito: a qualidade de vida relacionada à condição bucal medida pela versão brasileira do OHIP-Edent e a Satisfação com as próteses por meio de uma escala visual analógica “Visual analog scale” (VAS), que combina a percepção do paciente em relação à satisfação geral com o conforto, estabilidade, capacidade para mastigar, capacidade para conversar e estética. Os resultados mostraram que houve redução de 33.3% nos impactos negativos da condição bucal na qualidade de vida (p<0,001) e melhora da satisfação em relação às próteses superior e inferior (p<0,01) em relação ao inicio e após 30 dias da finalização do tratamento. A melhoria da qualidade de vida ocorreu em todas as dimensões do OHIP-Edent (p<0.001): mastigatória, psicológica, social e dor e desconforto relacionados à prótese. Apesar da redução significativa nos impactos na qualidade de vida (p<0,001), e aumento significativo na satisfação com as PT superior (p<0,01) e inferior (p<0,001), não houve diferenças entre o Protocolo Simplificado e o Protocolo Tradicional em relação aos escores do OHIP-Edent, e a satisfação com a PT superior/inferior. Concluiu-se que, além dos aspectos funcionais e estéticos, a confecção de próteses totais tem impactos favoráveis sobre a qualidade de vida e satisfação do paciente com as próteses. O protocolo simplificado resulta em percepção dos desfechos do tratamento pelos pacientes semelhante ao protocolo tradicional.

Abstract Purpose Aim of this exploratory study was to investigate whether a retrospective assessment of oral health-related quality of life (OHRQoL) using the Oral Health Impact Profile (OHIP) is susceptible to bias such as implicit theory of change and cognitive dissonance. Methods In this prospective clinical study, a sample of 126 adult patients (age 17–83 years, 49% women) requiring prosthodontic treatment was consecutively recruited. The OHRQoL was assessed using the 49-item OHIP at baseline and at follow-up. Additionally, patients were asked at followup to retrospectively rate their oral health status at baseline (retrospective pretest or then-test) and the change in oral health status using a global transition question. Furthermore, patients’ ratings of overall oral health and general health were used as validity criteria for the OHRQoL assessments. Response shift was calculated as the difference between the initial and retrospective baseline assessments. Results Baseline and retrospective pretest did not differ substantially in terms of internal consistency and convergent validity. Response shift was more pronounced when patients perceived a large change in OHRQoL during treatment. Retrospective pretests were more highly correlated with the baseline than with the follow-up assessment. Conclusion Findings suggest that retrospective assessments of OHRQoL using the OHIP-49 are susceptible to bias. Cognitive dissonance is more likely to appear as a source of bias than implicit theory of change.:Inhaltsverzeichnis 1. Einführung in die Thematik…………………………………………………2 2.

AS-Patienten leiden häufig unter schlechten Mundgesundheitsverhältnissen, die sich möglicherweise auch in einer beeinträchtigten mundgesundheitsbezogenen Lebensqualität (MLQ) widerspiegeln. In der aktuell verfügbaren Literatur werden Zusammenhänge bezüglich der MLQ bei Patienten mit AS und krankheitsrelevanten AS-Parametern bislang nicht beschrieben. Mögliche Interaktionen in diesem Kontext sind unklar. Zudem steht das subjektive Wohlbefinden zur Beurteilung eines Behandlungserfolges nicht immer in unmittelbarem Zusammenhang mit der Verbesserung des klinischen Krankheitsbildes der AS. Ziel dieser Studie war es, die MLQ bei Patienten mit AS und einer gesunden Kontrollgruppe zu eruieren. Zusätzlich sollten Assoziationen zwischen MLQ und dem Mundgesundheitszustand (dental/parodontal) sowie bedeutsamen AS-spezifischen Parametern bewertet werden. Zudem sollte die MLQ in Bezug auf den oralen Gesundheitszustand innerhalb der AS-Gruppe und innerhalb der gesunden Kontrollgruppe getrennt verglichen werden. In die Untersuchung wurden 50 diagnostizierte und therapierte AS-Patienten eingeschlossen. Das durchschnittliche Alter dieser Patienten lag bei 47,18 ± 15,67 Jahren. Von den 50 AS-Patienten waren 24 Studienteilnehmer weiblich. Entsprechend Alter und Geschlecht wurde eine Kontrollgruppe (K) aus 50 allgemein Gesunden zusammengestellt. Hier lag das durchschnittliche Alter bei 55,82 ± 10,56 Jahren; 27 der 50 Probanden waren weiblich. Die zahnärztliche Untersuchung umfasste einen zahnärztlichen Befund (DMF-T) sowie die Bewertung der parodontalen Situation. Zur Beurteilung des parodontalen Zustandes wurden die parodontale Sondierungstiefe (ST) und der klinische Attachmentverlust (AV) mit einer millimeterskalierten Parodontalsonde erhoben. Mithilfe von ST und/oder AV erfolgte die Einteilung der Parodontalerkrankung in gesund/milde, moderate oder schwere Parodontitis. Des Weiteren wurde zur Beurteilung der MLQ die deutsche Kurzform des Oral Health Impact Profiles (OHIP-G14) verwendet. Neben der statistischen Signifikanz wurde nach dem Prinzip des minimalen signifikanten Unterschieds auch die klinische Relevanz betrachtet. Alle statistischen Analysen, wie der t-Test, der Mann-Whitney-U-Test, der Chi-Quadrat-Test und der exakte Fisher-Test, wurden mit der Software SPSS Statistics (Version 22, IBM) durchgeführt. Unterschiede zwischen den Gruppen wurden als signifikant für p-Werte <0,05 (zweiseitig) angesehen. Während die gesunde Kontrollgruppe ein signifikant höheres mittleres Alter aufwies (AS= 47,18 ± 15,67; K= 55,82 ± 10,56; p<0,01), fielen Geschlecht und Rauchgewohnheiten vergleichbar aus (p>0,05). Bei den AS-Patienten wurde ein höherer D-T (AS= 2,68 ± 3,42; K= 0,02 ± 0,14; p<0,01) und F-T (p=0,02) sowie ein schlechterer Parodontalzustand (p=0,01) im Vergleich zu K festgestellt. Der OHIP-G14-Summenscore fiel in der AS-Gruppe statistisch signifikant höher aus als in der K-Gruppe (AS= 6,2 [2; 0-10,75]; K= 1,7 [0; 0-2,0]; p<0,01). Zudem wurden die Aspekte der einzelnen Fragen bewertet: „verschlechterter Geschmack“ (p=0,05), „weniger zufriedenstellendes Leben“ (p=0,01), „schwer zu entspannen“ (p=0,01), „Spannungsgefühl“ (p=0,01), „unangenehm zu essen“ (p<0,01), „kurzatmig“ (p<0,01), „Schwierigkeiten beim Ausüben von Arbeiten“ (p<0,01), „Funktionsunfähigkeit“ (p=0,01), „Mundschmerzen“ (p=0,01) und „Gefühl der Unsicherheit“ (p=0,02), wobei diese bei AS signifikant höher als bei den K-Probanden eingeschätzt wurden. Die Ergebnisse bezüglich der Assoziation von OHIP-G14 und den oralen Befunden zeigten, dass in der AS-Gruppe DMF-T, DT, MT und Schweregrad der Parodontalerkrankung keinen signifikanten Zusammenhang mit den OHIP-G14-Werten aufwiesen (p>0,05). Dagegen wurde ein signifikanter und nahezu klinisch relevanter Zusammenhang zwischen DMF-T (p=0,01) und MT (p=0,01) zu den OHIP-G14-Werten in der K-Gruppe identifiziert. Innerhalb der AS-Gruppe waren die AS-spezifischen Parameter BASDAI (p<0,01), BASFI (p=0,04) und BAS-G (p=0,03) statistisch signifikant und klinisch relevant mit den OHIP-G14-Werten assoziiert. Darüber hinaus standen das Vorhandensein von „geschwollenen Gelenken“ (p=0,04), „schmerzhaften Gelenken“ (p<0,01), „Morgensteifigkeit“ (p=0,01), „Einschränkung der Bewegungsfähigkeit des Alltags“ (p=0,04), „Probleme bei Alltagsdingen“ (p=0,01), „physischer Schmerz“ (p=0,04) und „Probleme, sich selbst zu pflegen“ (p<0,01) ebenfalls statistisch signifikant und klinisch relevant mit den OHIP-G14-Werten im Zusammenhang. Schlussfolgernd ist festzustellen, dass die untersuchten AS-Patienten im Vergleich zur gesunden Kontrollgruppe einen schlechteren oralen Zustand und eine schlechtere subjektiv wahrgenommene MLQ zeigten. Dabei standen die Parameter für die Mundgesundheit bei der AS-Gruppe nicht mit den OHIP-G14-Werten in Verbindung. Im Gegensatz dazu zeigte die Mehrheit der AS-spezifischen Parameter einen signifikanten Zusammenhang mit den Ergebnissen der subjektiv wahrgenommenen MLQ. Somit weisen Patienten mit AS im Vergleich zu K-Probanden eine schlechtere subjektiv wahrgenommene MLQ auf, die nicht mit ihrem oralen Status zusammenhängt. Die hohe Belastung aufgrund der allgemeinen Erkrankung scheint einen wichtigen psychosozialen Effekt auszuüben, der sich auf die MLQ betroffener AS-Patienten auswirken könnte.:1 Einleitung …..….….…………………………………….…………………………………………1 1.1 Einführung ……………………………………………………………………………….1 1.2 Erkrankungen der Mundhöhle ......…………………………………………………….2 1.2.1 Karies .………………………...………………………………………………………….2 1.2.2 Parodontitis ...……………………………………………………………………………3 1.3 Ankylosierende Spondylitis ………………………………………………………….…6 1.4 Assoziation zwischen Ankylosierender Spondylitis und Lebensqualität ………......8 1.5 Mundgesundheitszustand und Bedeutung der mundgesundheitsbezogenen Lebensqualität bei Patienten mit Ankylosierender Spondylitis .……………………9 1.6 Zielsetzung und Fragestellung der vorliegenden Studie ..……...………………...12 2 Publikationsmanuskript ………………………………………………………………………...13 3 Zusammenfassung der Arbeit .………………………………………………………………...22 4 Ausblick …….……………………….…………………………………………………………..25 5 Literatur …....…………………………………………………………………………………….26 6 Darstellung des eigenen Beitrags ...…………………………………………………………..33 7 Erklärung über die eigenständige Abfassung der Arbeit ..…………………………………35 8 Lebenslauf ………………………………………………………………………………………36 9 Danksagung …………………………………………………………………………………….37

Abstract The retention of a complete denture and the patient’s adaptation varies considerably among different individuals. Resorption of the edentulous alveolar ridge differs greatly and some patients need implant-retained overdentures to enable adequate retention of their prostheses. In some extreme cases it is necessary to increase the volume of the alveolar ridge with bone grafts. The aim of this study was to examine the outcome of implant-supported overdenture treatment conducted in Oulu University Hospital. The aim was also to assess the impact of treatment on oral health-related quality of life and patient satisfaction. The study group was comprised of patients treated with a mandibular or maxillary implant overdenture and a group of patients with extreme mandibular bone resorption treated with extraoral bone grafts and implants. The treatments were performed in 1985–2013 thus also providing long-term results. The results of this study showed predictable and successful treatment outcomes also among elderly patients and in severe situations with bone deficiency. The most frequent complication in the clinical follow-up was loosening of the retention mechanism, commonly noted in other previous studies. Despite some minor mechanical defects in prosthetic structures or mild mucosal inflammation around the implants, they did not hinder everyday use of the prostheses. Neither the number of supporting implants nor the connection type seemed to have a great impact on patient satisfaction. Older patients with a mandibular overdenture seemed to be most satisfied. In conclusion, treatment with implant overdentures seems to be successful also in the long-term. / Tiivistelmä Kokoproteesin pysyvyys ja potilaan sopeutuminen proteesiin vaihtelee huomattavasti eri yksilöiden välillä. Hampaattoman luuharjanteen resorptiossa on eroja, ja osalle potilaista implanttikiinnitteinen peittoproteesi on välttämätön riittävän proteesin pysymisen mahdollistamiseksi. Hyvin pitkälle edenneissä luuharjanteen resorptioissa voi leukaluun lisääminen luusiirteillä olla tarpeellista. Tutkimuksen tarkoituksena oli selvittää Oulun yliopistollisessa sairaalassa tehtyjen implanttikiinnitteisten peittoproteesihoitojen tuloksia. Tavoitteena oli myös arvioida hoidon vaikutusta suunterveyteen liittyvään elämänlaatuun ja potilastyytyväisyyteen. Tutkittava ryhmä koostui potilaista, joille oli valmistettu alaleukaan tai yläleukaan implanttikiinnitteinen peittoproteesi, ja potilasjoukosta, jolle hyvin pitkälle edenneen luuresorption vuoksi implanttihoito oli tehty luusiirteiden avulla. Hoidot tehtiin vuosina 1985–2013, ja tutkimuksissa voitiin arvioida myös peittoproteesihoidon pitkäaikaistuloksia. Tutkimus osoitti, että hoitotulokset olivat ennustettavia ja onnistuneita myös iäkkäillä potilailla sekä potilailla, joilla luupuutos oli kaikkein vaikein. Yleisin todettu komplikaatio kliinisessä tutkimuksessa oli proteesin kiinnitysmekanismin löystyminen. Pienet proteesirakenteiden rikkoutumiset tai lievät limakalvon tulehdusreaktiot implanttien ympärillä eivät kuitenkaan haitanneet proteesin toimintaa ja päivittäistä käyttöä. Peittoproteesia tukevien implanttien määrällä tai kiinnitystyypillä ei todettu olevan suurta vaikutusta potilastyytyväisyyteen. Kaikkein tyytyväisimpiä vaikuttivat olevan iäkkäät potilaat, joille oli tehty alaleuan peittoproteesi. Tutkimus osoittaa, että implanttikiinnitteinen peittoproteesihoito on menestyksellistä myös pitkällä aikavälillä.
