Thermology is the study and application of bio-thermal process to assess health or disease while thermography is a technique of measurement of skin temperature distribution on the body over a given period of time. It is a noncontact, noninvasive method that utilizes the heat from an object to detect, display, and record thermal patterns and temperature across the surface of the object and it employs images and visually evaluates the thermal changes. The principle of thermography is based on the amount of blood circulation at different layers of the skin, as it varies, the temperature also changes accordingly. Consequently, disorders that affect the blood flow too result in abnormalities in temperature distribution and these when evaluated will provide valid diagnostic information. Thermography is being used to detect various pathological conditions in the medical and dental field. Various orofacial conditions in which thermography can be used are chronic orofacial pain, temporomandibular joint disorders, quantification of thermal insult to pulp, assessing inferior alveolar nerve deficit, and detection of herpes labialis in prodromal phase. Here, we discuss with the history, basics, and various applications of thermography in dentistry.
