Saliva is secreted by the parotid, submandibular, and sublingual glands in the mouth. It functions to protect the oral cavity from trauma and infection, aid in digestion by secreting enzymes, and maintain a balanced pH through buffering. Saliva secretion is stimulated by the sight and smell of food and helps lubricate and protect tissues, start carbohydrate digestion, and prevent dental cavities through its antibacterial properties.

Secretions of the Oral Cavity: Saliva
Saliva plays several important roles in oral health. It lubricates and protects the mouth, influences oral bacteria, and contains immunoglobulins, white blood cells, and electrolytes. The major salivary glands are the parotid, submandibular, and sublingual glands, which produce 95% of saliva flow. Saliva secretion is stimulated by eating and helps maintain oral pH balance and tooth mineral content. Saliva also plays a role in dental plaque and calculus formation and the development of caries, as certain bacteria metabolize carbohydrates in saliva to produce acids that demineralize teeth.
Physiology of saliva
This document discusses the anatomy, physiology, and clinical considerations of salivary glands and saliva. It describes the major and minor salivary glands, their development, histology, nerve supply, and role in saliva formation. The composition, functions, regulation and diagnostic uses of saliva are examined. Clinical topics covered include dry mouth, Sjogren's syndrome, effects of medications, and disorders of hyposalivation and hypersalivation.
Saliva and caries
Saliva plays an important role in oral health by forming a protective coating, regulating pH, and providing minerals that strengthen teeth. Reduced saliva flow can be caused by radiation, certain drugs, or illness and increases the risk of dental caries. For patients with dry mouth, conservative measures like drinking water and avoiding irritants can help. Stimulating saliva production with gum or lozenges and using saliva substitutes can also relieve symptoms. Close dental monitoring and preventive strategies like excellent plaque control, fluoride use, and chlorhexidine application are needed to manage caries risk.

This document summarizes a research article about mouth dissolving films as a novel drug delivery system. Mouth dissolving films are thin films that rapidly dissolve on the tongue or in the oral cavity within minutes to release medication. They offer advantages over tablets for patients who have difficulty swallowing. The document discusses the formulation of mouth dissolving films, which typically contains polymers, plasticizers, flavors, colors and sweeteners. It also reviews the absorption of drugs from the oral cavity and ideal characteristics of mouth dissolving drug delivery systems.
Saliva
The salivary glands secrete saliva into the oral cavity. There are three major salivary glands - the parotid, submandibular, and sublingual glands. Minor salivary glands are also present. Saliva is composed primarily of water but also contains enzymes, mucus, and ions. The composition of saliva varies between species and is regulated by the autonomic nervous system in response to eating. Saliva serves several functions, such as lubricating food for swallowing, regulating oral pH, and initiating starch digestion.
