Pulp temperature test (cold and hot diagnosis)

Use a cotton ball to dry the examined tooth and adjacent teeth, spray it on the small cotton ball with ethyl chloride and immediately place it on the adjacent tooth, so that the patient has a feeling of normal pulp reaction, then swab the tooth to observe the pain. reaction. Basic Information Specialist classification: oral examination classification: biochemical examination Applicable gender: whether men and women apply fasting: fasting Tips: Keep room temperature at 18 ~ 25 ° C (preferably 20 ° C) to eliminate the influence of external temperature. Normal value The cold and hot diagnosis was normal. Clinical significance Cold diagnosis First use a cotton ball to dry the examined teeth and adjacent teeth, spray the small cotton balls with ethyl chloride and immediately place them on the adjacent teeth, so that the patient has a feeling of normal pulp reaction, then wipe the teeth and observe whether there is any Pain response. In the absence of ethyl chloride, ice cubes can be used instead of ice cubes. The measurement site is generally located in the middle third of the neck of the cheek and cheek. The enamel is thin and easy to conduct temperature. 2. Hot diagnosis Check with a heat-softened tooth gel or impression gel that burns more than the skin of the finger can tolerate. The method is the same as the cold diagnosis method. Precautions 1. Stay awake and calm to rule out the effects of high levels of nervous activity. 2, lying down and relaxing for more than half an hour to measure, in order to rule out the effects of muscle activity. 3. Keep room temperature at 18 ~ 25 ° C (preferably 20 ° C) to eliminate the influence of external temperature. 4, before the fasting 12 to 14 hours, and the last meal should be light, but not full, to rule out the effects of food special dynamic effects. 5, first measure the basal body temperature to rule out the effect of body temperature (for every 1 °C increase in body temperature, the basal metabolic rate increases by about 13%). Inspection process Cold diagnosis method: firstly use the cotton ball to dry the examined tooth and the adjacent tooth, spray it on the small cotton ball with ethyl chloride and immediately place it on the adjacent tooth, so that the patient has a feeling of normal pulp reaction, and then wipe the tooth To observe whether there is a pain response. In the absence of ethyl chloride, ice cubes can be used instead of ice cubes. The measurement site is generally located in the middle third of the neck of the cheek and cheek. The enamel is thin and easy to conduct temperature. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks May cause an oral infection.
