  2. 1. Lactobacillus characterization and effects on oral biofilm composition

    Author : Nelly Romani Vestman; Ingegerd Johansson; Jukka Meurman; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lactobacillus; L. gasseri; probiotic traits; oral biofilm; breastfeeding; oral microbiota; odontologi; Odontology;

    Abstract : The human body is home for millions of bacteria. The largest microbial community is located in the gastro-intestinal (GI) tract, including the oral cavity with >700 identified taxa. Lactobacillus, which is normal inhabitant of the GI tract, contributes to health by possible biofilm and immune modulation. READ MORE

  4. 2. Responses to External Cues in Oral Bacteria

    Author : Carolina Robertsson; Claes Wickström; Gunnel Svensäter; Julia R Davies; Mattias Collin; Malmö universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oral Microbiology; Oral Biofilms; Saliva; Salivary mucin MUC5B; Streptococcus; Actinomyces;

    Abstract : This thesis investigates responses to external cues in oral bacteria on a molecular level. Paper I maps Ser/Thr/Tyr phosphorylated proteins in relation to the general proteome in an oral commensal streptococcus (Streptococcus gordonii DL1). READ MORE

  5. 3. Adhesion-related interactions of Actinomyces and Streptococcus biofilm bacteria

    Author : Mirva Drobni; Nicklas Strömberg; Karl-Eric Magnusson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biofilm; Actinomyces; Streptococcus; adhesion; Cariology; Cariologi;

    Abstract : Adhesion of bacteria is a key event in biofilm formation and is mediated by bacterial adhesins recognising host or bacterial partner receptors. In oral biofilm formation, primary Actinomyces and Streptococcus colonizers adhere to salivary pellicle proteins such as proline-rich proteins (PRPs) as well as to mucosal surfaces. READ MORE

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

    Author : Marjan Dorkhan; Malmö högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  7. 5. Influence of a dental ceramic and a calcium aluminate cement on dental biofilm formation and gingival inflammatory response

    Author : Katarina Konradsson; Jan van Dijken; Rolf Claesson; Lars Gahnberg; Umeå universitet; []
    Keywords : cements; ceramics; cytotoxicity; dental biofilm; gingivitis; interleukin-1; oral hygiene; resin composite;

    Abstract : Dental restorative materials interact with their surrounding oral environment. Interaction factors can be release of toxic components and/or effects on biofilm formation and gingiva. In the end of the nineties, a calcium aluminate cement (CAC) was manufactured as a “bioceramic” alternative to resin composite. READ MORE
