Description

Technical Field

[0001] The utility model relates to the technical field of dental medical devices, in particular to a pulp vitality test probe with a heat conduction sleeve. Background Technique

[0002] Thermal testing of pulp vitality is a commonly used method for evaluating the health status of the pulp. Generally, the middle 1 / 3 of the crown or the 1 / 3 near the neck of the buccal (labial) surface is selected. A heated tool is gently contacted with the selected part of the tooth to be tested, and the patient's reaction is observed, including the presence or absence of pain, the degree of pain, the duration of pain, etc. The pain of normal pulp will disappear quickly, while the pain of diseased pulp is more intense and will last for a longer time.

[0003] Chinese Patent Publication No. CN 219579107 U discloses a temperature measuring piece for pulp vitality testing, which relates to the technical field of dental medical devices. The temperature measuring piece for pulp vitality testing includes a heat conduction piece and a storage piece. The heat conduction piece has a first accommodation cavity. The heat conduction piece can be deformed under the action of an external force. The first accommodation cavity is used to place a first reagent. The heat conduction piece is used to contact the tooth. The storage piece is placed in the first accommodation cavity and has a second accommodation cavity. The second accommodation cavity is used to place a second reagent. The storage piece is made of a brittle material. The first reagent can chemically react with the second reagent;

[0004] For the above-mentioned temperature measuring piece for pulp vitality testing, the chemical reaction between the first reagent and the second reagent generates high temperature. The high temperature is transmitted to the contact end through the heat conduction piece, and then the contact end contacts the pulp, so as to detect the pulp vitality of the patient. However, the contact end of the above-mentioned temperature measuring piece for pulp vitality testing has a small area and a hard texture, which will cause excessive extrusion of the patient's pulp when contacting the pulp. In addition, the thermal vitality test of the pulp is carried out when the doctor is not sure which tooth of the patient is diseased. Therefore, the doctor needs to use the test device to detect each tooth one by one, and the time required for one-by-one detection is relatively long. However, the time for the first reagent of the above-mentioned temperature measuring piece for pulp vitality testing to chemically react with the second reagent is limited and cannot meet the detection needs.
