Pulp active fluorescent detecting device and detecting method

Abstract

The invention provides a pulp-vitality fluorescence detection device and a detection method, by employing fluorescence for detection, the modulated exciting light after passing through a filter is transmitted by a transmitting fiber, and irradiates the surface of a detected tooth via a probe window and drives the tooth to produce fluorescent radiation, then the modulated exciting light is received and transmitted by a receiving fiber in the probe window, and is transferred to a glimmer detection unit via a receiving filter, and then the modulated exciting light enters into a data processing and control circuit for being controlled and processed. The invention resolves professional difficult problems which include painless detection of dental diseases and particularly the fast synthetic detection of pulp vitality, tooth decalcification and carious dentin, the detection is accurate, and the corresponding data can be directly displayed. By applying the invention, the detection is flexible because one point detection and multi-point detection can be chosen, the detection procedure is capable of rejecting operation mistakes, the detection is rapid, visual and accurate, the detection range is large, and the structure is simple. The invention can be used in places such as stomatological hospitals, dental clinics, etc., in which dental diseases are detected.

Description

technical field [0001] The device of the invention belongs to the technical field of medical detection equipment, and is a detection device for oral cavity teeth, specifically a fluorescence detection device and a detection method for detecting pulp vitality. Background technique [0002] Pulp vitality test is an important link in the diagnosis and treatment of endodontic diseases. Traditional detection methods, such as pulp electrical vitality test and temperature test, show the reflection of the sensory nerve in the pulp, which is inaccurate due to certain subjectivity. Simultaneously, the stimulation of these detection means can increase the misery of the patient. At present, electric vitality tester is widely used in the detection of pulp vitality in China. It uses a gradient voltage from low to high to stimulate the patient's teeth. When the patient feels pain, the voltage level is recorded to judge the tooth's vitality. The lower the pain-sensing voltage, the more ac...

AI Technical Summary

Problems solved by technology

It is a device for cleaning and health care of the oral cavity. It does not have the function of detecting dental diseases, nor can it detect the status of dental pulp vitality.

[0006] The Chinese patent publication number is: CN1703162A "system and method for detecting dental caries", which also cannot directly display the data of pulp vitality, and cannot perform data and image storage, transmission or communication with a high-speed information processing system

[0007] Although the above patents use fluorescence technology, some of them can only be used to detect dental caries, and some can only detect whether the teeth are clean or not. None of them can detect more dental disease items, let alone the state of pulp vitality.

Of course, data and image storage, transmission or communication cannot be carried out with the high-speed information processing system.

[0008] The project team of this invention has searched domestic and foreign patent documents and published journal papers, and has not found any reports or documents closely related to the present invention.
