  1. 11. Salvadora persica (MISWAK) : an effective way of killing oral pathogens

    Författare :Abier Hamed Sofrata; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Miswak; Salvadora persica; chewing stick; traditional medicine; gingivitis; periodontitis; dental plaque; plaque pH; salivary flow; acid production; microelectrodes; oral hygiene; subgingival microbiota; antibacterial agent; isothiocyanate; chromatography; Porphyromonas gingivalis; Aggregatibacter actinomycetemcomitans;

    Sammanfattning : Mechanical removal of dental plaque is regarded as an effective means of controlling the progression of dental caries and periodontal disease. The habitual use of chewing sticks (Miswak) as an oral hygiene method is still wildly spread throughout parts of Asia, Africa, and the Middle East. LÄS MER

  3. 12. Acid Tolerance of Streptococcus Mutans Biofilms

    Författare :Jessica Neilands; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Acid tolerance; Streptococcus mutans; Biofilms; Acid stress; Fluoride;

    Sammanfattning : Mikrobiologisk forskning har till stor del bedrivits genom att man odlat bakterier i näringslösningar och på agarplattor och sedan studera bakterierna på olika sätt. Detta sätt att odla bakterier överensstämmer inte särskilt bra med hur bakterier växer i verkligenheten. LÄS MER

  4. 13. Cariological Studies on Endodontically Treated Teeth

    Författare :Khalid Merdad; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Caries risk; Caries susceptibility; Cariogram; Endodontic treatment; Jönköping; Sweden; Micro-CT; Recurrent caries; Saudi Arabia;

    Sammanfattning : Caries might jeopardize the long-term successful outcome of endodontic therapy. Therefore, it is of an interest for the endodontist to evaluate caries susceptibility of root-filled teeth (RFT). In the present thesis, several studies were conducted to explore this relationship.

  5. 14. Re-evaluation of methods to identify individuals with increased risk of caries

    Författare :Anna Senneby; Malmö högskola; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; caries; risk assessment; diagnostic accuracy; methodology; acid tolerance; reliability; agreement;

    Sammanfattning : The overall aim of this thesis was to evaluate methods used to identify individuals with increased risk of coronal caries lesion development. The specific aims were to:•evaluate the accuracy of different methods used to identify individuals with increased risk of developing dental coronal caries lesions (study I)•design and pilot a novel classification system for the assessment of caries lesion progression in bitewing radiography and to report rater agreement of the system (study II)•assess intra-individual differences in biofilm acid-tolerance between different tooth surfaces and inter-individual variation as well as stability of acid tolerance over time (study III)•assess diagnostic accuracy of two established methods and a candidate method to identify adolescents with increased risk of dental coronal caries lesion development (study IV).
