The International Association for the Study of Pain (IASP) has defined pain as “an unpleasant sensory and emotional experience associated with actual or potential tissue damage or described in terms of such damage." The most common dental complaint is pain, accounting for more than 80%of all dental visits. Pain diminishes the quality of life for many people, although it also may be a vital teacher or a warning message to be heeded. How humans process pain is a complicated, individualized process affected by genetics, personality, life experiences and straight forward physiological process.
