Pulp vitality temperature detector

Abstract

The invention discloses a pulp vitality temperature detector structure. The structure comprises an insulating and heat-insulating shell (1) and is characterized in that an extensional insulating temperature-conducting cold end (2a) and an insulating temperature-conducting hot end (2b) are arranged at two ends of the insulating and heat-insulating shell (1) and can be contacted with the dental face; a cold end temperature control system and a hot end temperature control system are arranged inside the insulating and heat-insulating shell (1); when a general switch (3) is pushed to the gear of'refrigeration', the temperature at the cold end can be quickly reduced to 10 DEG C or below and stably kept for cold diagnosis; and when the general switch (3) is pushed to the gear of'heating', the temperature at the hot end can quickly rise to 60 DEG C or above and is kept stable for hot diagnosis. According to the pulp vitality temperature detector, the temperatures at the cold end and the hot end are stable and visible, so that examination results can be relatively scientific and repeatable and have high credibility and accuracy; furthermore, the pulp vitality temperature detector is convenient to use, safe and reliable.

Description

technical field [0001] The invention relates to a dental pulp vitality temperature tester, which belongs to the technical field of dental medical aids. Background technique [0002] Dental pulp is the soft tissue located in the pulp cavity, which is surrounded by hard tissues such as dentin and enamel, and has important physiological functions. When there are external stimuli, such as bacterial infection, physical and chemical stimulation, or immune response, etc., pulp disease will be caused, and bacterial infection is the main cause. Clinically, endodontic diseases can be divided into many types, and the clinical manifestations and treatment prognosis of each type are different. It is of great significance to accurately locate the affected teeth and judge the pulp status of the affected teeth. For the diagnosis of endodontic disease, the pulp vitality test is a very important step. Among them, the electric pulp vitality test can only be used to reflect the presence or abs...

Problems solved by technology

However, the above methods have obvious disadvantages: ①The temperature of the cold and hot stimuli is not easy to control. If the temperature of the cold stimuli is higher than 10°C, or the temperature of the hot stimuli is lower than 60°C, the test results are unreliable and may Cause misdiagnosis and missed diagnosis; ②When cold water or hot water is used as the stimulation source, the teeth around the suspicious tooth under examination will often be stimulated due to the excessive fluidity of the water. If there is a reaction of pulpitis, the clinician will mistakenly think that the tooth under examination is a diseased tooth, resulting in a misdiagnosis; ③ To provide cold and heat stimulation sources, it is necessary to be equipped with refrigerators, alcohol lamps and other facilities at the same time, the cost is high, and the burning alcohol lamp has Security risks
