23. It has an average protein concentration of 1.5-2 mg/ml.
24. Cost of shipping & Storage tend to be lower.Informative analytes are present in lower amounts in saliva than in serum. DISADVANTAGES
25. Whole saliva collection Ductal secretions collection Parotid secretions collection Sub mandibular & sub lingual secretions collection Saliva collection
26.
27. RNA analysis: Add 1.65µL of SUPERase inhibitor.(2)Invert gently to mix. (3)Store all fractions at -80ºc.
28. Salivary/Oral Fluid Biomarkers Possibilities of Use DNA Standard genotyping Genetic information of the hosting human body Bacterial infection (oral microbes in the mouth) Diagnosing carcinomas of head & neck Forensics mRNA Information on transcription rates RNA Viral/bacterial identification Proteins Genetic information Translational regulation Diagnosing periodontitis Detecting dental cavities Immunoglobulin Diagnosing viruses Metabolites Diagnosing periodontitis
37. VIRAL DISEASES:Acute hepatitis A & B were diagnosed based on the presence of IgM antibodies in saliva.HIV:Salivary IgA levels.BACTERIAL INFECTIONS:By monitoring the presence of antibodies to microorganisms found in saliva & oral cavity
41. HORMONE MONITORING: Steroids like cortisol, aldosterone, testosterone, insulin SIALOCHEMISTRY ANALYSIS: Early monitoring of an exposure to lead, cadmium, mercury because of higher salivary levels of these elements
53. CONCLUSION: The components of saliva act as a “Mirror of the body’s health”, widespread use and growing acceptability of saliva as a diagnostic tool is helping individuals, researchers, health care professionals and community health programs to better detect and monitor diseases and to improve the general health of the public
