Objectives of Study: |
This study will recruit approximately 50 healthy individuals without oral diseases from Nankai University. Saliva collection will be conducted on weekday afternoons between 2:00 PM and 4:00 PM. Prior to collection, project staff will record participants' basic information and administer questionnaires regarding their lifestyle habits, medical history, medication use, and dietary intake. A preliminary oral examination will also be performed to assess hygiene, periodontitis, oral mucosal conditions, and other relevant diseases. Eligible subjects who pass the screening are required to fast for two hours before the collection procedure. They must rinse their mouths with alcohol-free mouthwash and water. Subsequently, unstimulated saliva will be collected twice using sterile saliva collection devices, with a 5-10 minute interval between collections. Details such as collection time and volume will be recorded for each sample. Following collection, the saliva samples will be immediately centrifuged to separate the supernatant. The supernatant will then be aliquoted and stored frozen at -80°C. Subsequent in vitro polyphenol intervention experiments will be performed on the saliva samples. The treated samples will be analyzed for various physicochemical properties, including salivary protein composition, friction coefficient, and the amount of salivary protein precipitate. |
