  • Periodontitis Etiology, Diagnosis, Current and Future Therapy. A Literature review 

    Skare, Kariann (Master thesis; Mastergradsoppgave, 2017-05-18)
    It is becoming clear that periodontitis is an inflammatory disease initiated by oral microbial biofilm, and likely due to poor oral hygiene and the failure of host immune system. Host response to the bacterial biofilm by the production of cytokines and subsequently inflammation response destroys the periodontium in the pathogenesis of the disease. This could lead to loosening or loss of teeth. In ...
