ABSTRACT:Saliva is a useful diagnostic fluid for periodontal diseases. Observing salivary biomarkers for oral and systemic diseases could become an important complement to clinical examinations in preventing periodontal disease in early stage. Periodontal diseases are mainly the inflammation of tooth supporting structures which affects gingiva, periodontal ligament, and alveolar bone. Recent findings indicate that it is possible to detect biomarkers for oral diseases within saliva samples. The aim of this research will be to investigate if known salivary biomarkers could be used for detection of periodontal diseases. Materials and Methods: A randomly selected sample of adults (20–89 years), living in Thunder Bay, will be invited to participate. 100 individuals will be examined clinically using standard examination procedures. Participants will be divided in 2 groups. First group will receive the results of the examination and if any participant will be susceptible for periodontal disease, they will be advised to take professional care according to their results. Second group will be the control group. Stimulated saliva samples will be collected and analysed for concentrations of IL- 1b, -6, -8, lysozyme, matrix metalloproteinases (MMP)-8 and tissue inhibitor of metalloproteinase (TIMP)-1 using ELISA, immunofluorometric assay or Luminex assays. The effect of using saliva as a biomarker will be evaluated by measuring clinical attachment loss (CAL) at the beginning of the study and after 5 years. The measurements of CAL will be taken every 6 months during the period of 5 years. The comparison of control group and the test groups will be done by analysis of variance (ANOVA) statistical test.

ABSTRACT:Most of poorly water soluble fails to solubilize because of their particle size, to overcome this particle size reduction upto nano level is most appropriate solution. Many times microsize have also its limitation therefore nano level size reduction is selected. Conversion to nano level involves many physical as well as chemical methods, but in physical method drug may be degraded hence chemical method is selected to achieve nanoparticles. Quasi emulsion solvent method is used to prepare nanoparticles of simvastatin by using Pluronic F-68 stabilizer. And suitable concentrations were selected by using 32 factorial designs.KEY WORDS: Nanoparticles, Quasi emulsion solvent technique.
