  1. 1. 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

  3. 2. Responses to External Cues in Oral Bacteria

    Författare :Carolina Robertsson; Claes Wickström; Gunnel Svensäter; Julia R Davies; Mattias Collin; Malmö universitet; []
    Nyckelord :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;

    Sammanfattning : 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). LÄS MER

  4. 3. Fluoride concentration in plaque and saliva and its effects on oral ecology after intake of fluoridated milk

    Författare :Kristina Engström; Svante Twetman; Lars G Petersson; Göran Dahllöf; Umeå universitet; []
    Nyckelord :children; enamel; demineralisation; fluoride; lactic acid; laser fluoroscense; milk; plaque; saliva; salivary bacteria; odontologi; Odontology;

    Sammanfattning : According to WHO, the addition of fluoride to milk could be considered as an alternative to water fluoridation for community-based caries prevention in childhood. School-based schemes in developing as well as industrial countries have demonstrated substantial benefits on oral health, but there are limited data available on the local events in the oral cavity after consumption of fluoridated milk.

  5. 4. Bacteria-agglutinating glycoproteins in human saliva : an in vitro study with special reference to Streptococcus mutans

    Författare :Jan Rundegren; Umeå universitet; []
    Nyckelord :agglutinin; glycoprotein; saliva; streptococcus mutans;

    Sammanfattning : The activity and specificity of salivary glycoproteins (agglutinins) aggregating various human indigenous microorganisms were studied in vitro. The agglutinin reacting with a serotype c strain of Streptococcus mutans was isolated and chemically characterized.The results can be summarized as follows:1. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
