Evaluation of Rheological Properties of Saliva by Determining the Spinnbarkeit

Saliva is crucial to maintaining oral health and facilitating chewing, swallowing, and speech functions. Decreased saliva secretion, known as hyposalivation, impairs these functions and increases the risk of dental caries and other infectious diseases in the oral cavity.Saliva exhibits various rheological properties, with mucin being a factor in determining these properties. Alterations in these properties can also affect the sensation of dry mouth. In this article, we focus on the spinnbarkeit of saliva using the Neva Meter instrument and provide a methodology for fully understanding the appropriate conditions for its use.
