  1. 1. Properties of Interfacial Proteinaceous Films with Emphasis on Oral Systems

    Författare :Cecilia Hahn Berg; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; Livsmedelsteknik; trypsin; SDS elutability; statherin; salivary proteins; salivary pellicle; proline-rich proteins; plaque control; mucins; microbial adhesion; lubrication; krillase; intraoral friction; hydroxyapatite; gelatin; exchange; enzymes; ellipsometry; dental plaque; degradation; colloidal probe; calcium-induced precipitation; adsorption; atomic force microscopy; total internal reflectance fluorescence spectroscopy;

    Sammanfattning : The present thesis addresses three issues related to proteinaceous films at solid/liquid interfaces: adsorption, lubrication and enzymatic interactions. Most of the work has been devoted to oral systems. In addition, gelatin has been investigated as a model protein. LÄS MER

  3. 2. 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

  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. On the adsorption behaviour of saliva and purified salivary proteins at solid/liquid interfaces

    Författare :Liselott Lindh; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acidic proline-rich proteins; adsorption; BSM; diffusion; ellipsometry; interfaces; mass transport limitation; mucins; MUC5B; saliva; salivary proteins; statherin; surface properties;

    Sammanfattning : Den salivfilm som bildas genom selektiv proteinadsorption på ytor i munhålan har stor profylaktisk betydelse genom sin skyddande funktion och befrämjar därigenom oral hälsa. Några av de adsorberade komponenterna har smörjande funktion (t ex muciner, sura prolinrika proteiner (PRP) och statherin), som är viktig bl a för att förhindra slitage mellan tandytor vid tuggning och hos gnisslare.

  7. 5. On the structure and mechanical properties of in vitro salivary pellicles

    Författare :Hannah Boyd; Javier Sotres; Thomas Arnebrant; Rob Barker; Mark Rutland; Malmö universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Salivary pellicles display exceptional hydration and lubrication performance. At present, there are still gaps in the understanding of how this is achieved. LÄS MER
