Assay of Oral Polymorphonuclear Neutrophils for Assessment of Oral Inflammation in Pregnant Women

Huda, Sabrina 20 November 2012 (has links)
Background: A multitude of studies suggest an association between periodontal disease and adverse birth outcomes. Although the evidence is controversial, it is biologically plausible, and the key link maybe inflammation. Purpose: To correlate levels of periodontal disease as measured by conventional methods with PMN counts from an oral rinse in pregnant women. Methods: Sixty-three pregnant women were recruited. Periodontal examinations were carried out. Fifteen-second saline rinses were collected. ABTS, a colour changing redox agent was added to each rinse. The intensity of the colour reaction was measured by absorbance to count the oral PMNs. Results: A statistically significant difference in oral PMN counts was observed between those with periodontal disease and the healthy patients (P < .05). The sensitivity and specificity using the bleeding index was 0.94 and 0.76 respectively. Conclusions: The rinse assay can be used as a screening tool for periodontal disease and oral inflammation in pregnant women.

Orofacial conditions and oral health behavior of young athletes: A comparison of amateur and competitive sports

Richter, Lisa 30 January 2023 (has links)
Körperliche Gesundheit und maximale Leistungsfähigkeit gelten im Spitzensport als oberste Priorität. So können akute Schmerzen im Mund-, Kiefer-, Gesichtsbereich sowie funktionelle Beschwerdebilder zu Ausfällen, mangelnder Regeneration und Leistungseinbußen führen. Obwohl eine entsprechende Beachtung im Profisport von zahlreichen internationalen Organisationen wie FDI, IOC und UEFA gefordert wird, belegen Studien, dass Leistungssportler unterschiedlichste Defizite des Mungesundheitszustandes aufweisen. Insgesamt gibt es nur wenig verfügbare Daten, daher war es ein Ziel der Dissertation zu Grunde liegenden Studie, klinische Daten zu oralen Entzündungen, Karieserfahrung, craniomandibulären Dysfunktioen sowie Erosionen (orofaszialer Gesundheitsstatus) von jungen Spitzensportlern in Deutschland zu erheben und diese im Vergleich zu einer Kontrollgruppe einzuordnen. Ein weiterer Fokus lag auf der Erfassung des Mundgesundheitsverhaltens dieser speziellen Kohorte um eine Einschätzung der Bedeutung diese Faktor auf den vorliegenden Mundgesundheitszustand zu ermöglichen.:1.

Evaluation du rôle de l'inflammation buccale sur l'athérogénèse dans la survenue des accidents vasculaires cérébraux ischémiques / Evaluation of the role of oral inflammation in atherognesis in the occurrence of ischemic stroke

Lafon, Arnaud 16 October 2013 (has links)
Le but de ce travail est d’étudier le lien suspecté entre l’inflammation buccale et la survenue des AVC ischémiques. Dans les pays occidentaux, l’incidence des infarctus cérébraux est en augmentation malgré les campagnes de prévention visant à limiter l’exposition aux facteurs de risque classiques des pathologies ischémiques. Près de 9% des accidents vasculaires cérébraux sont sans étiologie connue. Le facteur déclenchant de l’AVC ischémique ou le « key trigger » reste inconnu. Des études récentes montrent qu’un AVC ischémique est plus susceptible de se déclencher dans la semaine qui suit un événement infectieux. De ce fait, l’inflammation buccale entraînant une élévation de différents biomarqueurs inflammatoires est susceptible de favoriser la survenue des AVC. Dans un premier temps, une méta-analyse a été effectuée afin de faire la synthèse des données étudiant la relation entre l’inflammation buccale et la survenue des AVC. Elle a montré que le risque d’avoir un AVC ischémique fatal augmente de 38% chez les sujets atteints de parodontite sévère. Dans un deuxième temps, deux études cliniques observationnelles ont été mises en place afin de renforcer la validité des liens épidémiologiques supposés et d’apporter de nouveaux éléments dans la compréhension des mécanismes physiopathologiques liant l’inflammation buccale et la survenue des AVCI. Les résultats montrent une relation entre le degré d’inflammation buccale et les marqueurs biologiques athéromateux et inflammatoires. En effet, nos résultats montrent une augmentation des taux de CRP, de VLDL, de triglycérides et une diminution des taux de HDL lors d’une atteinte parodontale sévère. C’est la perte osseuse parmi les marqueurs cliniques de l’inflammation buccale aisément évaluable sur un panoramique dentaire, qui est la plus significativement liée au risque de la survenue des AVC ischémiques. Les résultats de cette thèse suggèrent que la présence d’un contexte buccal inflammatoire favoriserait la survenue le développement d’un AVCI. En outre, nos résultats confirment la nécessité d’une coopération entre l’odontologue et le neurologue afin d’améliorer la prise en charge du risque vasculaire chez un patient ayant un AVCI avec une inflammation buccale. / The aim of this work is to investigate the suspected link between oral inflammation and the occurrence of ischemic stroke. In Western countries, the incidence of ischemic stroke is rising despite prevention campaigns aiming at limiting the exposure to common risk factors for ischemic diseases. Nearly 9% of strokes are of unknown etiology. The triggering factor for ischemic stroke or "trigger key" remains unknown. Recent studies have shown that ischemic stroke is more likely to occur in the week following an infectious event. Therefore, oral inflammation, that causes a rise in various inflammatory biomarkers is studied as potentially increasing the risk of stroke. Firstly, a meta-analysis was performed to synthesize data about the relationship between oral inflammation and the occurrence of stroke. It has shown that the risk of fatal ischemic stroke increases by 38% in patients with severe periodontitis. Secondly, two observational clinical studies have been implemented to strengthen the validity of the supposed epidemiological links and bring new elements in our understanding about the pathophysiological mechanisms linking oral inflammation and the occurrence of ischemic stroke. The results show a proportional relationship between the degree of oral-inflammation and biological assessments that demonstrate pro-atherosclerotic and pro-inflammatory state. Indeed, we observe an increase in CRP levels, VLDL triglycerides and a decrease in HDL in patients with severe periodontal disease. Bone loss, that is easily measurable on a dental panoramic radiograph, appears to be the main risk factor of the occurrence of ischemic stroke.The results of this thesis show that the presence of an inflammatory oral environment is an additional marker for the discovery of a cardiovascular risk in patients combining other conventional risk factors of ischemic stroke. In addition, our results suggest the need for cooperation between the neurologists and odontologists to improve the management of cardiovascular risk in patients with ischemic stroke and oral inflammation.
