Saliva research focuses on studying the composition, function, and properties of saliva, which is a watery fluid produced by the salivary glands in the mouth. Saliva plays a key role in digestion, taste perception, oral health, and speech. Researchers examine the various components of saliva, such as enzymes, proteins, electrolytes, and antibodies, to understand their roles in maintaining oral health and overall well-being. Saliva research also explores how changes in saliva composition can be indicative of certain diseases or health conditions, and how saliva can potentially be used as a diagnostic tool for detecting various health disorders.
