Pain is a common human complaint and can be alarming, especially when an individual cannot provide a proper explanation. It seriously impairs the lives of millions of individuals around the world and remains the main reason why a patient reports to the doctor. A lot of research has been done and is still going on to understand the physiology of pain and to invent ways and means to eliminate or control the intensity, duration and frequency of this factor which affects quality of life of individuals. Many theories have been proposed over the years and a knowledge of them will help us to understand the complexity of pain.Keywords

Orofacial thermoreception results in qualitatively diverse percepts of temperature as the result of complicated central neural mechanisms along the thermosensory pathways to the cortex. Foods that enter the mouth and objects that touch the face often have temperatures that differ from the orofacial tissues. The resulting transfer of thermal energy evokes discharges in, or alters the ongoing discharge activity if different classes of thermoreceptors supplying the epithelia. The different classes of thermoreceptors differ in their response properties and explain human's capacity to distinguish between thermal stimuli at very high to very low temperatures.
Introduction : A cool drink of water, a hot cup of coffee, a warm glass of flavored milk. Qualitatively different adjectives such as hot, cool, warm describe our perception of a single dimension of stimulation that of temperature or thermal energy. Signal from temperature sensitive receptors or thermoceptors in the orofacial region contribute greatly to the enjoyment of foods. Foods that enter the mouth and objects that touch the face often have temperatures that differ from the orofacial tissues.
