Description
Technical field
The present invention relates to the stomatology technology field, be specifically related to a kind of radio frequency microplasma oral cavity root canal disinfection device.
Background technology
The odontopathy disease incidence rate accounts for first of each organ disease of human body, at present, the prefered method of internationally recognized, treatment dental pulp disease and periapical disease be root canal (root canal therapy, RCT).Root canal therapy generally includes three basic steps: root canal preparation, root canal disinfection, root-canal filling, and root canal disinfection is important step in the root canal.
Root canal disinfection mainly contains following several method:
First kind is formaldehyde cresol formocresol (FC) disinfecting drug, FC is the common drug of department of stomatology clinical treatment pulp gangrene and residual pulpitis, because of its formaldehyde can combine with proteinic various intermediate products of corruption and end product, and generation innocuous substance, the cresol generation soap that can combine with putrid fatty product, formaldehyde cresol formocresol has stronger deodorization again simultaneously, bactericidal action and be subjected to oral cavity doctor's welcome, be present the most frequently used sterilization method, but usually need further consultation repeatedly.People recognize that gradually the formaldehydes medicine has stronger cytotoxicity and hapten in recent years, can be distributed in the dental pulp, dentin, periodontal membrane of treatment tooth and alveolar bone on every side, thereby cause the reaction of anaphylaxis stomatitis or systemic anaphylaxis, excite bronchial asthma etc., even put forward carcinogenic problem.
Second kind is the calcium hydroxide disinfectant preparation, is the medicine that is used for root canal disinfection in recent years, has strong basicity, and various bacteria in the root pipe is had killing action, and also may penetrate into performance bactericidal action in the dentinal tubule, and zest is little, safety non-toxic.But the mechanism of its antibiotic and sterilizing mainly is the pH value in the calcium hydroxide silt-root pipe, make the antibacterial in the root canal system in alkaline environment, be difficult for survival, or make change on the bacterial cell recurring structure, cause the increase of bacterial membrane permeability, lipid oxidation, protein denaturation etc. and cause antibacterial death; Calcium hydroxide also has inducing action simultaneously, can promote the reparation of periapical tissue, and certain density calcium hydroxide can improve alkaline phosphatase activity in the tissue, promotes tip of a root sclerous tissues deposition, is beneficial to the sealing of apical foramen of tooth.But administration time takes 7-10 days at least, needs further consultation 1-3 time, comparatively time-consuming consumption power and have the strain selectivity and shortcoming such as effect is low, and domestic popularization degree is not high.
The third is the laser sterilization, is maximum root canal disinfection method of studying at present, reduce patient's consultation time, and curative effect is comparatively definite.The high temperature that moment produces during the laser irradiation tissue of tooth can be killed the antibacterial in the root pipe, its metabolite of deactivation, after laser energy is absorbed by biological substance simultaneously, transform light energy is become chemical energy, cause the change or the destruction of microorganism macromole original structure, cause microbial death.But, being difficult to reach apical area at backteeth optical fiber, Disinfection Effect is poor; Laser makes the local high temperature that produces, and may produce damage to surrounding tissue; Optical fiber passes apical foramen of tooth and directly acts on periapical tissue, can make its necrosis, edema; Laser has changed the structure on root surface, and whether this change can exert an influence to treatment, also unknown.
The 4th kind is microwave sterilization, and its mechanism is the comprehensive function of heat effect and non-thermal effect, studies show that microwave has good sterilization, the effect by microwave with and good penetration performance deactivation and antibacterial and the endotoxin thereof on the degraded root canal wall.But the heat effect of microwave may cause partial structurtes to change and tissue injury.
The 5th kind is ultrasonic disinfection, and the preparation effect is cleaned in main performance, and the bactericidal action of itself is faint in the preparation root pipe process; Particularly commute forms biomembranous enterococcus faecalis and obligate anaerobe etc.
