PhysiologyThe enteric nervous system, also known as the gut-brain, is a network of neurons that controls the muscular activity of the gastrointestinal tract. It is capable of operating independently of the central nervous system but can be modulated by it. Its main function is to regulate motility and secretion within the GI tract, which includes coordinating peristaltic contractions that propel food and facilitate mixing and absorption.

Dental Materials Etching of tooth surface with 37% phosphoric acid creates microporosities in the enamel and dentin. This is the main method of adhesion of composite resin to tooth surface.
After etching the surface energy of the enamel will increase. This will make it very sticky to any kind of contaminants. If salivary contamination will occur, the salivary proteins will precipitate in the microporosities. This will prevent the adequate penetration of the bonding agent, therby reducing the micotag formation. Hence, complete isolation is essential.
