The clinical success, survival and failure of titanium-ceramic tooth-supported constructions submitted to patients at the Faculty of Odontology, Malmö University - A retrospective clinical study

Blom, Åsa, Mahlberg, Marie January 2017 (has links)
Syfte:Syftet med föreliggande studie var att utvärdera kliniskt lyckande, överlevnad och misslyckande för metal-keramiska singelkronor och broar med underkonstruktion av titan som lämnats ut till patienter på Odontologiska fakulteten, Malmö högskola. Material och metod:För att svara på den aktuella frågeställningen identifierades patienter som mellan åren 2011-2015 fått fastsittande protetiska konstruktioner i titan-keramik, på Odontologiska fakulteten, Malmö högskola. Patienterna undersöktes av två tandläkarstudenter, under deras åttonde termin (april 2016), med visuell-taktil metod. Resultat:47 stycken patienter ingick i studien, detta motsvarade 69% av alla patienter som matchade inklusions - och exklusionskriterierna. Hos dessa 47 patienter fanns totalt 67 konstruktioner med en medelålder på 35 månader och en medianålder på 29 månader. Av de inkluderade konstruktionerna var 47 stycken singelkronor och 20 broar. Den kliniska lyckande, överlevnad och misslyckande frekvensen för singelkronorna var 55%, 43% och 2%, medan den för broarna var 15%, 70% och 15%. Slutsats:Inom studiens begränsningar har följande slutsatser dragits: •De titan-keramiska singelkronorna utlämnade till patienter på Odontologiska fakulteten, Malmö högskola, hade en högre lyckandefrekvens än de titan-keramiska broarna.•Resultatet indikerade en övergripande hög lyckande- och överlevnadsfrekvens för titan-keramiska konstruktioner. / Aim:The aim of this study was to evaluate the clinical success, survival and failure rate of titanium-ceramic single crowns (SCs) and fixed dental prostheses (FDPs) submitted to patients at the Faculty of Odontology, Malmö University. Materials and Method:To answer the research question, patients with SCs and/or FDPs made in titanium-ceramic at the Faculty of Odontology, Malmö University, between year 2011-2015, were identified and later examined by, two dental students during their eight semester (April 2016), with a visual-tactile method. Results:The study contained a total of 47 participating patients, this outcome represented 69 % of all the patients found matching the inclusion and exclusion criteria during the patient selection. Out of the 47 participants, 67 restorations were obtained and examined. The 67 restorations that were included in the study had a mean age of 35 months and a median age of 29 months. Out of these, 47 were SCs and 20 were FDPs. The clinical success, survival and failure rate of the SCs were 55%, 43% and 2%, respectively. The clinical success, survival and failure rate of the FDPs were 15%, 70% and 15%, respectively. Conclusion:Within limits of this study the following conclusions were made:•The titan-ceramic SCs submitted to patients at the Faculty of Odontology, Malmö University had a higher success rate compared to the FDPs.•The results indicate an overall high and acceptable success and survival rate for the titan-ceramic restorations.

Étude rétrospective sur l’efficacité du peroxyde d’hydrogène dans les pulpotomies de molaires primaires

Dumais Pelletier, Sarah-Eve 07 1900 (has links)
Objectif : L’objectif de cette étude rétrospective est d’évaluer l’efficacité clinique et radiologique du peroxyde d’hydrogène 3% dans les pulpotomies de molaires primaires et de les comparer aux pulpotomies faites avec une dilution 1:5 de la formule de formocrésol de Buckley. Méthode : Les données cliniques et radiologiques de 401 molaires primaires traitées par pulpotomies avec un suivi minimum de 24 mois, sauf en cas d’échec, ont été obtenues des dossiers de 216 enfants. Résultats : Aucune différence statistiquement significative n’a été observée entre les résultats des pulpotomies au formocrésol et au peroxyde d’hydrogène à l’analyse clinique (p=0,435) et radiologique (p=0,2447). La probabilité cumulative de survie clinique était supérieure ou égale à 98% pour les molaires traitées au formocrésol et 99% pour celles traitées au peroxyde d’hydrogène, à tous les temps de suivi, variant de 19 mois à 106 mois. Radiologiquement, la probabilité cumulative de survie au 24e mois était de 81% pour le formocrésol et de 91% pour le peroxyde d’hydrogène. Conclusions : Le peroxyde d’hydrogène a démontré des taux de succès clinique et radiologique comparables à ceux du formocrésol pour les pulpotomies de molaires primaires. / Purpose: The objective of this retrospective study was to evaluate the clinical and radiological success of 3% hydrogen peroxide in primary molar pulpotomies and compare them to pulpotomies made with a 1:5 dilution of Buckley’s formocresol formula. Methods: Clinical and radiographic data of 401 pulpotomized primary molars with a minimum follow-up of 24 months, except in cases of failure, were obtained from the records of 216 children. Results: No statistically significant difference was observed between the results of formocresol and hydrogen peroxide pulpotomies clinically (p = 0.435) and radiologically (p = 0.2447). The cumulative probability of clinical survival was greater than or equal to 98% for molars treated with formocresol and 99% for those treated with hydrogen peroxide at all follow-up periods, ranging from 19 to 106 months. Radiologically, the cumulative probability of survival at 24 months was 81% for formocresol and 91% hydrogen peroxide. Conclusion: Hydrogen peroxide has demonstrated clinical and radiological success rates comparable to those of formocresol in primary molar pulpotomies
