Non Elastic Impression Materials. Dentin (/ ˈ d ɛ n t ɪ n /) (American English) or dentine (/ ˈ d ɛ n ˌ t iː n / or / ˌ d ɛ n ˈ t iː n /) (British English) (Latin substantia eburnea) is a calcified tissue of the body and along with enamel cementum and pulp is one of the four major components of teethIt is usually covered by enamel on the crown and cementum on the root and surrounds the entire pulp.
In physics a force is an influence that can change the motion of an objectA force can cause an object with mass to change its velocity (eg moving from a state of rest) ie to accelerateForce can also be described intuitively as a push or a pull A force has both magnitude and direction making it a vector quantity It is measured in the SI unit of newton (N).
