JP2015113338A - Peeling of plaque in periodontal pocket and bactericide - Google Patents

Abstract

PROBLEM TO BE SOLVED: To peel plaque in a periodontal pocket in the location where an instrument is physically hard to reach, from a root surface safely, and to sterilize bacteria within the plaque.SOLUTION: Peeling and sterilization of plaque in a periodontal pocket can be performed by injecting mixture of around 3% hydrogen peroxide gel and around 10% of urea peroxide gel into a periodontal pocket, or injecting a thin bar-like stick of water-soluble solid containing around 10% of urea peroxide crystal into a periodontal pocket.

Description

When removing plaque in the periodontal pocket, the present invention makes it easy to peel the plaque from the root surface to a place where it is physically difficult to reach the device, and can be expected to have a bactericidal effect. The present invention relates to a plaque exfoliating and disinfecting agent comprising the above chip.

Previously, plaque in the periodontal pocket was removed with a manual scaler or ultrasonic scaler to treat or prevent periodontal disease, but the device reached a complex place in the periodontal pocket in a blind operation. It was difficult and the plaque was left behind.

In addition, even if an attempt is made to detach and sterilize the periodontal pocket with a liquid disinfectant, it is difficult to detach the plaque from the root surface by irrigation in the pocket. Since it is a liquid, it immediately flows out of the pocket and it is difficult for the disinfectant to penetrate into the plaque.

In addition, popidone iodine is a bactericidal agent that can be used for the oral mucosa, but it may cause anaphylactic shock due to iodine.
Another commonly used disinfectant is oxidol, a hydrogen peroxide solution of around 3%, which can be used relatively safely and is effective for exfoliating from the root surface of plaque by reacting with catalase. The reaction instantly decomposes into oxygen and water, and lacks foaming power and sustainability of bactericidal properties.

An object of the present invention is to safely detach plaque from a root surface and disinfect bacteria inside the plaque in a place where it is difficult to reach an instrument in a periodontal pocket.

About 3% hydrogen peroxide gel and about 10% urea peroxide gel are mixed immediately before being injected into the periodontal pocket, and then injected into the periodontal pocket to first form a gel-like hydrogen peroxide catalase. Oxygen foaming occurs due to an instantaneous reaction with the above, and the foaming force causes the plaque to peel from the root surface, and a gap is formed in the aggregation of the plaque, so that the gel-like urea peroxide permeates there.
Since hydrogen peroxide can be continuously supplied by decomposition of urea peroxide, a continuous peeling effect and a bactericidal effect can be expected.

Alternatively, a solid thin rod-shaped chip made of a water-soluble thickener such as carboxymethylcellulose containing about 10% urea peroxide crystals is injected into the periodontal pocket and dissolved gradually with moisture such as saliva. Hydrogen peroxide can be supplied, and a continuous peeling effect and bactericidal effect can be expected.

The present invention relates to about 3% hydrogen peroxide gel and about 10% urea peroxide for plaques in complex places that could not be physically removed by a manual scaler or ultrasonic scaler in the periodontal pocket. The mixture of gels has an effect of supplying a continuous bactericidal power because the plaque is peeled off from the root surface by the foaming force of oxygen generated during the reaction with catalase and can be stored in the pocket for a long time due to the viscosity of the mixture.
Alternatively, a thin stick-shaped solid stick containing about 10% urea peroxide crystals is injected into the periodontal pocket and gradually dissolved, thereby providing a continuous plaque peeling effect and a bactericidal effect.
The main component of the present invention is hydrogen peroxide, which is active oxygen, but periodontal disease-related bacteria in the periodontal pocket are mostly obligate anaerobic bacteria and do not have catalase in the bacteria. Causes lethal damage to bacteria.
The catalase causing foaming is a catalase derived from tissue debris in the exudate in the pocket or a part of the host of the plaque.
Other bactericides that can be used in the oral cavity include popidone iodine, acrinol, benzethonium chloride, and chlorhexidine that can be used overseas, but none of them have the ability to foam.
Iodo and chlorhexidine are dangerous because there are many reports of anaphylactic shock.
As described above, the present invention is effective in the treatment and prevention of periodontal disease by peeling and sterilizing the plaque in the periodontal pocket.

About 3% hydrogen peroxide gel and about 10% urea peroxide gel, which are the components of the present invention, are mixed immediately before use and injected into the periodontal pocket with a syringe with a thin nozzle for 10 minutes. Let it stop.
Alternatively, a water-soluble solid thin stick-like stick containing about 10% urea peroxide crystals is injected into the periodontal pocket and allowed to stand for 10 minutes while being dissolved with water such as saliva.
After that, normal scaling and route planing are performed using a hand scaler and an ultrasonic scaler.

Claims (2)

Plaque removal and disinfectant in periodontal pockets with an admixture consisting of a mixture of around 3% hydrogen peroxide gel and around 10% urea peroxide gel. About 10% urea peroxide liquid is gelled with a water-soluble thickening agent such as carboxymethylcellulose, which is made into a thin film and dried to form a thin film.
Then, the plaque in the periodontal pocket is peeled off and sterilized, which is made of a thin rod-shaped solid chip containing 10% urea peroxide by thinly winding this film.
