Description

Instrument for visual periodontal treatment

Technical Field

The invention relates to the technical field of oral medical treatment, in particular to an instrument for visual periodontal treatment.

Background

Periodontal disease is a common disease in humans, and the primary treatment modalities are tooth cleaning and periodontal scaling. The tooth washing is that the calculus on the gum is cleaned and treated, and a doctor can directly look at the calculus, so that the operation is simple and easy. Periodontal scaling is considered a difficult point in the treatment of periodontal disease, which is to remove the diseased tissue in the periodontal pocket, including the widespread infected cementum and granulation tissue, randomly scattered in cord-like subgingival calculus attached to the root surface and macroscopic calculus islets.

Clinically, the boundary of the periodontal pocket cannot be directly observed and determined by naked eyes, and the periodontal pocket conjecture with lower accuracy needs to be carried out by means of a periodontal probe according to hand feeling conjecture, so that when a doctor carries out periodontal scaling, diseased tissues are easy to miss, infected tissues are not thoroughly removed, or accidental wounds damage healthy periodontal attachment, and finally, periodontal treatment complications such as bacteremia and the like are caused. According to the authority statistics, even the most experienced periodontal doctors can only clean up not more than 80% of the periodontal infected tissue including subgingival calculus.

Meanwhile, the more thorough mode of periodontal treatment is the mode of periodontal flap surgery scraping, but obviously, the mode has the disadvantages of large trauma, more complications and high cost and is not widely accepted and accepted by doctors and patients.

At present, a periodontal endoscope is available on the market, which mainly utilizes a thin (diameter of 1mm) optical fiber to be inserted into a gingival sulcus, overlooks the bottom of a periodontal pocket and transmits an image to a display screen, but the image is not clear, only root calculus can be observed, the edge appearance of the periodontal pocket cannot be observed, the reasons of flushing, complicated operation and the like are needed, and meanwhile, the purchase cost of equipment is up to million, so that the periodontal endoscope is not popularized clinically.

To this end, the chinese patent of invention discloses an apparatus for back-light scattering inspection of a dental crown (application No. 2017103839252) for transmitting back light of red electromagnetic waves through the dental crown for static diagnosis of hidden lesions located in the dental crown, such as small caries at the dental crown part, such as interproximal caries, secondary caries, etc., subgingival calculus at the neck of the tooth, etc., but after the product of the patent is used for 1-5 minutes, the laser starts overheating protection and is interrupted for use because of overheating, each time of detection is completed for many times, the efficiency is low, the treatment effect is poor, and simultaneously, many discomfort are brought to the patient; in addition, the product of the patent can not be used for observing the edge outline of the periodontal pocket (particularly the deep periodontal pocket), the infected objects in the deep periodontal pocket, real-time observation of periodontal scaling and the like, has a narrow application range and relatively low practical value.
