  1. 1. Studies on Pellicle and Early Dental Plaque in Relation to Periodontal Conditions

    Författare :Stefan G Rüdiger; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bacterial adherence; in vitro pellicle; in vivo pellicle; periodontitis-associated bacteria; gingival crevicular fluid; plasma proteins; dental biofilm; experimental gingivitis; chronic periodontitis; periodontal pocket; exposed root surfaces;

    Sammanfattning : Background and Hypothesis: Bacterial receptors in dental pellicles may influence colonisation and subsequent plaque formation. Studies on such receptors in the dental pellicles and bacterial adherence have mostly been performed in vitro and focused on proteins of salivary origin. LÄS MER

  3. 2. In vitro and in vivo studies of salivary films at solid/liquid interfaces

    Författare :Ida Svendsen; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; saliva; proteins; adsorption; ellipsometry; gel electrophoresis;

    Sammanfattning : A conditioning film, the pellicle, of which many salivary proteins areimportant constituents, covers the surfaces present in the mouth. The pellicleforms in a selective adsorption process, and it has protective and lubricatingfunctions as well as an influence on the adherence of oral microbes thatultimately leads to the development of dental plaque.

  4. 3. Effect of surface characteristics on cellular adherence and activity

    Författare :Marjan Dorkhan; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bacteria; microbial biofilm; dental implant; streptococci; oral bacteria; salivary pellicle; early colonizers; titanium oxide; microbial activity; oral keratinocytes; gingival fibroblasts; cell attachment; surface modification; anodic oxidation; anatase;

    Sammanfattning : Ersättning av förlorade tänder med tandimplantat är numera en vanlig behandlingsmetod med generellt goda resultat. Antalet implantatsystem på den internationella marknaden har ökat kraftigt under senare år. LÄS MER

  5. 4. Characterization of c-di-GMP signaling in Salmonella typhimurium

    Författare :Roger Simm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Signal transduction via cyclic nucleotides is a general mechanism utilized by cells from all kingdoms of life. Identification of cyclic diguanosine monophosphate (c-di-GMP) as an allosteric activator of the cellulose synthase in Gluconacetobacter xylinus 20 years ago, paved the way for the discovery of a novel general signalling system which is unique to bacteria.

  7. 5. On the role of plasma proteins in bacterial adhesion to dental surfaces

    Författare :Stefan G Rüdiger; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Bacterial receptors in dental pellicles could influence colonisation and subsequent plaque formation. Studies of such receptors in dental pellicles and bacterial adherence have often focused on proteins of salivary origin. We have only a limited knowledge of the receptor functions of plasma proteins reaching the pellicle via the crevicular fluid. LÄS MER
