Infrared thermography was examined as a means for determining pulpal vitality. The dominant thermal influence was found to be the condition of the supporting tissue. Some cases of infection erupting to the supporting structure showed increases to 4F. Without infection, no definite thermal distinction existed. Available infrared thermographic equipment can measure the temperature of any selected tooth in the dental arch with adequate sensitivity. All subjects showed an increase of several degrees Fahrenheit from incisor to molar. With few exceptions, paired teeth were the same temperature. Lateral symmetry thus became the condition for establishing temperature norms. A better condition for establishing temperature norms might be developed from long-term thermographic case histories. Departures from known thermal norms for an individual crewmember would then signal incipient dental distress. (Author)
