Description
Technical field
The present invention relates to medical treatment consumptive materials technical fields, specifically, be a kind of root canal disinfection core convenient for clinical manipulation and
Preparation method.
Background technique
Root canal treatment is present treatment dental pulp and periapical lesion, keeps the best approach that tooth does not pull out, and is in the world most
Common effective treatment method.And due to root canal treatment be by special equipment by mechanical method remove infection dental pulp and
The dentine and toxic substance of infection have its complexity, so the requirement for being really achieved thorough disinfection cleaning is not easy very much, then
Requirement to root canal disinfection is just very high, and requirement first can kill bacterium remaining in root canal, secondly can assist eliminating the tip of a root
The absorption of bacterium and Inflammatory substances in tissue, third can assist repairing impaired organization of root tips, help the closure of apical foramen of tooth,
4th root canal disinfection can prevent the generation of residual pulpitis, if root canal disinfection, which is not thorough, will lead to dental pulp subinfection again, therefore can
To say that root canal disinfection is the important step concerning root canal treatment success or failure.
Clinically root canal treatment includes: three root canal preparation, root canal disinfection and root-canal filling basic steps, therefore root canal is controlled
It is long to treat the course for the treatment of, needs multiple further consultation.Wherein current root canal disinfection process needs to import root canal disinfectant, and root canal disinfection
Medicament categories are single, it is difficult to position are sterilized needed for root canal disinfectant is sufficiently delivered to, root canal disinfectant action time has
Limit, cannot place for a long time in root canal, take out root canal disinfectant before next root-canal filling again and carry out drug irrigation, do
It is dry.This is that an operating process is cumbersome, the operating time is long, and the process of less effective.
Chinese patent application: CN103330628A discloses a kind of dental unit, is related to Medical Devices technology neck
Domain, the treatment water route including being provided with more exit branch connect and are provided with triple valve on the primary flow pipe of more exit branch,

| Treat two groups | 55 | 7 | 15 | 28 | 5 | 90.91% |
| Treat three groups | 56 | 5 | 18 | 25 | 8 | 85.71% |
The present invention has well adult men and women's pulp necrosis of different age group convenient for the root canal disinfection core of clinical manipulation
Therapeutic effect, effective percentage are higher than 96%.
The present invention uses wrap ping material root canal disinfectant, which has selected raw material appropriate and its matched
Have that sterile, disinfecting power is strong, wettability power is strong, smooth-shaped easily enters root canal than, obtained root canal disinfection core, it is strong after moisture absorption
The advantages of degree and toughness do not reduce.
Since the material of this root canal disinfection core has the advantages that smooth-shaped easily enters root canal, thus it is easy to use, it will not
Feeling of pain is caused to patient, secondly as its wettability power is strong, during treatment, the residual solution that will can be generated in root canal rapidly
And waste liquid absorbs, and patient is helped to restore as early as possible, furthermore, since it has the advantages that intensity and toughness do not reduce after moisture absorption, so
During use, the root canal disinfection core becomes fragile in root canal and then leads to the root canal in root canal after avoiding moisture absorption
The problem that disinfection core is festered, need to be drawn off and is again put into disinfecting drug in root canal, this mitigates for staff
Work load for the patient improves therapeutic effect, shortens treatment time, restores helpful to patient, meanwhile,
Waste of resource is avoided, and alleviates the financial burden of patient, there is very strong practicability and good application prospect.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
Member, without departing from the principle of the present invention, can also make several improvement and supplement, these are improved and supplement also should be regarded as
Protection scope of the present invention.
