A lubricant for root canal treatment

Abstract

The invention discloses a lubricant for root canal treatment, which comprises sodium edetate, citric acid, carbamide peroxide, cetyltrimethylammonium bromide, sodium carboxymethylcellulose, glycerin and water. The lubricant of the present invention can soften the root canal wall, reduce preparation resistance, and is especially suitable for the preparation of large-tapered nickel-titanium instruments. By comparing the use of root canal lubricant (experimental group) and no use of root canal lubricant (control group) two groups of experiments Similarly, the results of clinical trials show that the use of root canal lubricants in the root canal preparation process, the detection rate of bacteria in the root canal was significantly lower than that of the group without lubricants, indicating that the use of lubricants in the root canal preparation process helps to eliminate the bacteria in the root canal. Bacteria, creating conditions conducive to the healing of clinical chronic apical periodontitis.

Description

technical field [0001] The invention belongs to the field of dental root canal treatment, and in particular relates to a lubricant for root canal treatment, the main purpose of which is to remove the stain layer and infection that cannot be removed during the root canal mechanical preparation process. Background technique [0002] According to the survey, the adult incidence of oral diseases in China accounts for 60% to 80% of the Chinese population, among which the incidence of pulpitis, pulp necrosis, and apical periodontitis is relatively high. The most effective cure for these diseases is root canal treat. Especially for teeth with residual crown and root, if the prosthodontic department needs to carry out post-crown restoration, root canal therapy is the only treatment method that can be selected. [0003] Root canal treatment is to completely remove the source of infection in the root canal through debridement, mechanical and chemical methods. Because the root canal s...

Problems solved by technology

Phytic acid is a plant extract, which itself has a certain antibacterial effect, but the cell membrane of Gram-negative bacteria can block the permeability of its antibacterial components to the cell membrane, and Gram-negative bacteria have resistance to plant antibacterial substances. As a result, it cannot show antibacterial effect on Gram-negative bacteria, and it has poor antibacterial effect on Gram-negative bacteria. It cannot completely remove bacteria in root canal antibacterial aspects, and the existing lubricant itself The permeability is not good, and a higher concentration of EDTA is needed to complete the corresponding effect
