The present invention relates to a dental temporary root canal filler gutta percher cone containing nano silver and fragrance which are widely used for filling dental root canal in dental treatment.

The GATAPARKER cone has plasticity and good fit and closeness in the root canal, and is easy to operate and relatively low in toxicity to the root canal tissue, but it is not easily inserted into the narrow root canal, and it is difficult to completely seal the root canal. It is a weak point that breaks down and the antibacterial ability is low.

      As is known through mass media recently, more than 200,000 bacteria / cm 2 to 300,000 bacteria / cm 3 of bacteria are incubated in human hands, and the number of bacteria detected when washing and sterilization is neglected is approximately 5 million / 10,000 to 2 million to 3200 / ㎠ E. coli, 3500 to 2 million to 1100 / ㎠, severe cases of ticks, fungi, and even parasites were found in the airwaves recently reported, and more people in the medical industry Exposure to germs is embarrassing to hospital patients.

No one has ever been to the dentist in their lifetime, and what is reminiscent of dentistry is reminiscent of anesthesia needles and drills for grinding or drilling teeth.

Dentists have been eager to get rid of this or to remove plaque on the tooth surface, to fill tooth decay with amalgam, or to correct it as a part of aesthetic treatment.

Older adults may have had a procedure that once caused pain due to inflammation of their teeth, puncturing the inside of the tooth with an air drill to remove infected tooth tissue or painful nerves and pus.

At this time, it is a temporary root canal filling material (20) that punctures the inside of the tooth, removes contaminated nerves, tissues and pus, and temporarily fills it. Various types of temporary root canal fillers 20 having different lengths and thicknesses of the temporary root canal fillers 20 are commercially available depending on the depth.

The dentist measures the temporary root canal filler 20 with a ruler and tests the strength of the temporary root canal filler 20 prior to restoring the tooth that has been perforated with the temporary root canal filler 20. The insertion part 40 may be bent by hand, and the temporary root canal filling 20 is not stored in a sterilization apparatus, but stored in a corner of the unit chair or in a drawer or case filled with dust or inserted into a storage member. .

As you know, dental clinic most of the patient's source and when the tooth is finely dispersed tooth powder is blown in all directions, so the temporary root canal filling (20) is proliferating oral substances of others and a large amount of bacteria or viruses, If you don't know it, it's probably natural that oral irritation occurs after prosthetic work.

The present invention has been made to overcome the problems of conventional root canal treatment,

 For functional temporary root canal fillers prepared by injecting nano silver and fragrance into the gutta percher cone, which is used to clean, shape, and temporarily close the root canal after drug treatment. The present invention relates to a functional temporary root canal filling material (Gutta percher cone), which has strong antibacterial and bactericidal power, bio-friendly, and which does not leach harmful substances and irritates the root tissues compared to the conventional katapach cone. will be.

Temporary root canal filling used for root canal treatment is a treatment to remove tissue and fill the place with temporary root canal filling (20) material when it is infected with bacteria such as severe caries, gum disease, or nerve tissue of teeth. After anesthesia, the inflamed neural tissue is cut off and the space is sterilized and filled.

  Usually every two to three days about four to five times the treatment, in case of severe damage to the teeth to build a pillar inside. This treatment can help prevent toothache and prevent inflammation from spreading to the bone tissue surrounding the tooth roots.

If you don't remove the damaged nerve, the pain will be severe and you will have to infect your teeth and surrounding tissues and pull the teeth out. In contrast, dental caries is to remove only the enamel or dentin of the damaged tooth and fill the space. After this treatment, your teeth will be weakened because they are not nourishing your blood, so be sure to cover them with a crown.

Root canal treatment is called Endodontic treatment in English, which means Endo inside in Greece, and odont means tooth. Therefore, Endodontic treatment is a treatment for the inside of the tooth. To explain the root canal treatment, the basic tooth structure is as follows.

Inside the tooth there is a soft tissue called pulp, which is surrounded by a tissue called hard enamel and firm dentin, which consists of blood vessels and nerves. The dimension extends from the center of the crown to the end of the root and is connected to the blood vessels and nerves in the alveolar bone surrounding the root with a narrow hole located at the end of the root. Dimensions are very important during growth and development. Acts to protect the teeth from such stimuli by exhibiting pain in response to harmful stimuli applied to the tooth. However, if the pulp is infected by bacteria of the caries or inflamed by a harmful stimulus, the pulp is not nourishment in the pulp, and the pulp tissue dies, which requires root canal treatment.

If the pulp is inflamed or left in an infected state, it can cause severe pain, severe cases of swelling (a pus), and even more severe osteomyelitis of the mandible or maxilla.

Symptoms of pulp inflammation are pain, long-term discomfort when cold or hot, or discoloration of the teeth, swelling of the gums at the root end, or discomfort when touching adjacent gums. It may occur when there is no. With these symptoms and test data such as X-rays, the dentist will diagnose the damage to the pulp and follow up with root canal treatment.

The dentist will use the ventilated space to remove the inflamed or infected pulp, carefully disinfect the inside of the tooth, shape the space inside the tooth that had the pulp dimension to the proper shape, and restore the complete form and function of the tooth. It is sealed with a temporary root canal filler 20 containing nano silver and fragrance of the invention. Many endodontic treatments are performed to relieve toothache caused by inflammation or infection of the pulp.

With modern endodontic treatment, most patients say they are comfortable during treatment, and only a small amount of discomfort remains and disappears after a short period of treatment. In the presence of an infection or infection, the sense of sensitivity of the treated tooth may become sensitive.

This discomfort can be alleviated as a painkiller that is readily available from the surroundings, and even when the root canal treatment is complete, the treated tooth may continue to feel different from other senses. If pain persists for more than a few days, or when pressure is applied, or if the pain is very severe, it is inflamed by the gutta percher cone, a temporary root canal filling 20 inserted inside the perforated tooth. The patient should come to the dentist to remove the external restoration and the Gatapacha cone inside the tooth, sterilize the inside of the perforated tooth and insert a sterile new temporary root canal filling 20, the Gatapacha Con.

Root canal treatment, on the other hand, requires one to several visits, depending on the condition and undergoes the following steps,

1. The root canal doctor will examine the teeth and surrounding tissues visually, closely diagnose them through X-rays, perform anesthesia if necessary, and after the anesthesia, the dentist will treat a small rubber membrane called rubber dam The tooth to be placed inside is isolated from other teeth, thereby protecting the surrounding tissue during the procedure and preventing the inside of the root canal from being contaminated by saliva during the treatment.

2. The dentist will drill a hole in the crown with a handpiece (airdrill) through the hole and use an en-do file to remove the infected or inflamed pulp. In this case, X-ray (radiation) of the root canal to remove the dimensional necrosis, filth and inflammation in the root canal is clearly removed, and then the shape in the root canal is cleaned and appropriately shaped (180). May be completed at one time, but most of the root canal is very narrow, bent, so the procedure is time-consuming and difficult to require multiple visits.

3. The dentist fills the space inside the tooth through the material called gutta percher cone, the temporary root canal filling 20 of the present invention, which is suitable for living beings. Most of the holes formed in the teeth are temporary root canal fillings. The temporary root canal filling material (10) is closed before the tooth is covered with brass or ceramic and is converted into a temporary filling material (20).

4. After finishing the root canal treatment, you need to have a crown or prosthesis or other restoration to restore the complete shape or function of the teeth. If there is less hemorrhoids left on the teeth and the restoration is likely to fall off, the dentist will build a pillar in the teeth.

     When filling the root canal as described above, the filler 20 is used as a temporary filler to assist the infiltration of the root canal and completely close it, using a gutta percher cone or gutta percha cone. It is a vegetable extract of, and is provided in the form of a rubber solidified at room temperature by applying a semi-solid state, pressure, or heat, which is commonly called a white gutta-percha cone.

According to the present invention, the composition of the temporary root canal filler 20, which is nano silver and the filler 20 containing the fragrance, is a gutta percher cone, which is 5 to 40 wt% of a liquid polymerizable oligomer (Oligomer), and a plasticizer 1 To 20% by weight, 10 to 40% by weight of the biocompatible inorganic compound, 1 to 5% by weight of zinc oxide, barium sulfate 1 to 10% by weight, wax 1 to 20% by weight, pigments 1 to 5% by weight Nano silver is 0.01 to 20% by weight 0.011 to 10% by weight relative to the total weight of the temporary root canal filler, the particle size of the nano silver is 5 to 300 nm of the size of the entire composition of the katapach cone It is preferably added in a weight percent of the total weight, and agitated in a roll or a mixer to extract the plate and cut it into a conical shape for each size. Thus, the filling material 20, the katapache cone is used as the most used material today for the root canal treatment.

The present invention relates to the addition or coating 240 of nano silver and a fragrance to a conventional gutta percher cone, which is a dental temporary root canal filler 20,

In general, as a method for treating rotten teeth at the dentist, a rotten portion of the tooth is removed by using a puncture tool, and a root canal, which is a treatment site, is filled with a filling material and sealed. As the filler 20, calcium hydroxide adjuvant and the like have been used, and lately or latex or rubber-based katapach cones have been mainly used.

These tapachachone cones are plastic materials that are deformed according to heat or pressure, and are suitable for ease of fit, closure and manipulation, and have relatively low toxicity to root tissue.

 Disadvantages are that microleakage in the area and the tube near the alveolar are not sealed, which tends to cause bacteria to propagate. Because of the good radiographic transmission, it is difficult to visually identify the location of the temporary root canal during X-ray imaging. In case of using amine alone, side reactions occur during the reaction between epoxy and amine, and some of the amine groups remain unreacted immediately.Aromatic amine monomers have weaker skin irritation than aliphatic amine, but are ingested or absorbed during handling. There is a problem that can cause toxicity.

    The present invention is a guttapacha cone containing nano silver and fragrance in the body of the dental temporary root canal filler 20 which is essentially used for filling the root canal filler 20 temporarily in the root canal treatment tablets percher cone).

The present invention relates to a nano silver and a fragrance agent in the katapachone cone, which is a dental temporary root canal filling 20, which is a functional katapachone cone, and more particularly, the root canal washing, morphology, and drug treatment during the root canal treatment of teeth. It relates to the root canal filler 20 used to temporarily seal the root canal afterwards.

The present invention can be referred to as a novel invention for the public oral health to solve the problems of the conventional temporary root canal filler 20 to prevent the infection of the temporary root canal filler 20 using a nano-silver material.

The present invention relates to a temporary root canal filler 20 containing nano silver and a fragrance as described above, and the production of the body of the temporary root canal filler 20 in nano silver and fragrance without physical, chemical or electrical action. As it is applied to the city, it contains strong nano silver material which is economical and antibacterial and antimicrobial persistence is unparalleled.

Nano silver is a natural material that is harmless to humans and animals and has several ten times stronger sterilizing and antibacterial properties than chlorine.

If so, look at the special advantages of the temporary root canal filling (20) containing nano silver and fragrances

   1: Aging silver causes better antibacterial, sterilization, deodorization and detoxification functions than any fungicides, and when used in the body, silver ions and far-infrared rays are generated, which promotes blood circulation and endocrine activity.

         6: It has an ultraviolet blocking effect. Nanonized silver has excellent UV protection, so it is used in textiles, cosmetics, sunglasses, etc.

 When the temporary root canal filler 20 is stored, it can be used for a long time by preventing corrosion or discoloration by ultraviolet rays of the sun.

         7: Deodorizing effect and fragrance divergence effect. Even if the temporary root canal filler 20 is sterilized and used, the surface of the body of the temporary root canal filler 20 is attached with fine tooth powder or dust, which causes a disgusting smell. The liquid or powder of the vegetable fragrance (120) raw materials, such as fruit, aroma, herbal, and flower, is preferably 0.01 to 5% by weight, based on the total weight of the temporary root canal filler. By putting it in,

 In the body of the gutta percher cone (Gutta percher cone) of the temporary root canal filling 20 of the present invention always emits a gentle scent to the dentist and the procedure using the temporary root canal filling (20) (Gutta percher cone) It has the effect of pleasing the sense of smell of the receiving patient and further raising the atmosphere of the entire hospital, and furthermore, it is effective for the health and health of the people.

The present invention has been made to solve the problems of the prior art as described above,

The present invention provides a temporary root canal filler 20 made of various materials such as plastic, mineral, synthetic resin, silicon, paper, and latex after making silver powder or silver (Ag) solution, which is a technology different from general silver powder. In the body of the gutta percher cone, nano silver is mixed (260) or coated (240) at a content ratio ranging from 0.01% to 20% of nano silver (NANO SILVER) from 2 PPM to 999 PPM and the particle size of the nano silver is 5 to 300. With the particle size of ㎚, the liquid or powder of the fragrance (120) raw materials such as fruit, aroma, herb, flower, etc. is added at 0.01% to 10% based on the total weight of the temporary root canal filler, which is antibacterial and sterilized. The functional temporary root canal filler 20 having the function, deodorant effect, fragrance divergence effect, detoxification function, far infrared emission and silver ion radiation function was prepared to block infection and bacterial infection of patients and dentists. It leads the oral health has a purpose.

The present invention is excellent in biocompatibility and sterilization effect in order to solve the problems of the prior art described above, excellent fluidity, easy to be completely filled to the cutting edge, temporary temporary dental use of the new composition does not occur unpleasant odor when using Root canal decay

We want to provide a premise.

The present invention relates to the combination or coating of the nano silver 160 and the fragrance ash 180 to explain the silver and nano silver 160, the core material of the present invention in detail as follows.

As described above, when the nerve or tissue inside the tooth becomes infected and causes inflammation and pain, the dentist makes a hole in the surface of the tooth and removes the tissue or nerve of the inflamed area and then repairs the hole-extracted extraction site. It relates to the temporary or temporary temporary root canal filling (20) to be used (Gutta percher cone)

On the other hand, the current commercially available temporary root canal filling (20) gatpacha cone is composed of a standardized cone (cone) and an accessory cone (accessory cone), the standardized cone in the same form as the dental drilling (file) When the nerve treatment is made, puncture instrument is used to puncture the pulp infected part on the wall of the canal tube to remove the infected nerve tissue, and the filler 20 is applied to the wall of the root canal so that no source of infection occurs in the root canal. It is important to insert the pacha cone to fix the filler 20 to the main root canal and the adjacent canal so that it is in close contact with the root canal wall and the apex.

     In this way, when the root canal is filled, it is often used to check the state of filling inside the teeth through X-ray imaging and temporarily use it until there is no inflammation.

A removed excavator, an endodontic plugger or a moon group spreader is used to remove the remaining portion of the filler 20, which is inserted into the tooth of the filling material 20.

As mentioned above, there are many ways to fill the root canal.

Lateral condensation and vertical condensation are used.

 Lateral condensation method is generally the same as the working length of the root canal to be treated, and by inserting a tapa cone cone selected to fit the apex and inserting a tapered spreader into the remaining space to press it horizontally It is a method of filling the root canal by closely contacting the side wall of the root canal, inserting the auxiliary cone and repeating it.

The vertical condensation method is a device in which the filler 20 (cement or sealer) is applied to the root canal wall, the filler 20 is buried in the cone, inserted into the root canal, and the coronal cone is then heated. Cut out, heated spreader or hot heat carry

The procedure is performed by removing part of the cone using the fish.

As such, the lateral and vertical press methods require a device that can reach a temperature that can cut and melt the Gatpacha cone.

Since an alcohol lamp or the like, a spreader or a plugger has a lot of inconveniences, and thus a probe having a heat carrier capable of generating high heat may be used.

As a result, in the above, the side pressure method and the vertical pressure method for filling the root canal were examined.

As described above, the process of completely removing the pulp residue and bacteria in the root canal during the root canal treatment and then sealing the formed root canal in three dimensions is called root canal filling.

As a final step in root canal filling, seal it with a filler 20 of a gutta-percha cone, or promote cure by blocking stimulus sources that may remain in the root canal from penetrating the root canal tissue through the root canal; Recontamination must be prevented.

   The main material of the conventional gutta-percha cone 10 is zinc oxide, which is usually mixed and used until it is a mixture of oil and cream.

However, toxicity and inflammation have emerged as a problem of fillers containing zinc oxide, and problems that cause pain or re-treatment have begun to appear. In addition, it has been known that there is a problem such as curing too quickly or discomfort in a short working time and dissolving in tissue fluid. In addition, there is a radiopaque effect of confirming the state of treatment, it can be used to visually examine the current state of the inside of the tooth, it has become an essential condition in the dental temporary root canal filling (20).

Then, silver and nano silver, which is a constituent material of the present invention, will be described in detail in order to help understanding of the nano-silver-containing crown filler (Gutta-percha cone) of the present invention.

 Silver, the main component of nano silver, has been recognized as a precious metal of high value from ancient times, and has been the object of extraction. It is not only valued as a currency but also attracted attention as an important industrial material in modern industry. It is proportional in many ways. Silver was mined early in Europe's Mediterranean coast, where silver was produced from the Incas and Aztecs before the Americas discovery, and later from Peru and Bolivia.

 Silver flowed into Europe, and the flow of silver went from 1520 to 1800.

It has grown steadily, but has declined since the discovery of large amounts of silver in the early 19th century. Currently, the world's major silver producers are Russia (13.8%), Canada (13.5%), Mexico (13%), Peru (13%), United States (11%), Australia (8%), Poland (6%). The country's silver reserves are 17 million tons, and its reserves are about 9.2 million tons. As of 2002, the amount of silver produced in our country is about 5,000 kg, which is 1.2% of the total domestic demand. It's a very small amount.

Properties of silver: The color of silver is gray in the case of elegant gray-white metal or powder, specific gravity is 10-12, Mohs hardness is 2.5-3, and melting (80) point is 960.5 ℃.

In particular, the melting point of silver (80) is very important for temperature compensation of high thermometers, which is the standard of scientific and industrial temperature, and silver is the best conductor of metal, and is used comprehensively for contacts and other electronics. Optically, the reflectance of visible light is 90, which is one of the most excellent metals such as platinum, and pure silver does not form rust even when left in the air or heated, but it reacts with sulfur and hydrogen to make black emulsified silver. Special attention should be paid to the film of the camera.

     In addition, the mechanical properties change according to the amount of impurities (O2) contained in the silver, and the hardness of the heat-treated high-purity silver is Brinell hardness 25 to 27, tensile strength 12 to 16 kgf / mm2, and the tensile strength of the cast The strength is up to about 29 kgf / mm 2, the elongation is 48 to 54%, and the recrystallization temperature is 150 ° C.

    In particular, in the case of pure silver, the processed hardened material is softened by recrystallization at normal room temperature and softened softly. The malleability and flexibility are rich after gold.

     Silver's efficacy has been used as a tool to check the imbalance of the body that the person does not feel because the gloss or color changes depending on the condition of the body when worn on the body since ancient times. Fatigue or low rhythm) and Dongbobom said that it is effective in the prevention and treatment of mental disorders and gynecological diseases such as epilepsy and game. The five chapters are said to be comfortable, the mind and body are stabilized, and the main body records that the body is lengthened by chasing morale and lightening the body.

      Also, when the Black Plague prevailed in the Middle Ages, nobility of the black aristocrats and royals, who had many silverware and silver utensils, did not have black plague, which released silver to the extent that it was able to sterilize the Black Plague bacteria, making it relatively safe from infectious diseases. In the place where the royal family and the state guests were served, silver products were used habitually.

Briefly explaining the nano silver (NANO SILVER) extraction method and features in the present invention to help the understanding of the nano silver as follows.

The atomic weight of silver is 107.87 amu, and it has been known for a long time that silver (Ag) has bactericidal power. Nano Silver was first developed by a biotechnology company, a government subsidiary of our country, and was named Nano Silver as a compound name of the brand name Nano-technology and silver;

  Nano silver is an advanced antimicrobial agent that utilizes silver's strong antibacterial and bactericidal function and excellent electrical conductivity mechanism. Nano silver is unlikely to be resistant to bacteria, unlike conventional antibiotics. Nano silver has been shown to kill almost all single cell germs on the ground in a short time.

 Currently, a variety of products based on nano silver, consisting of powders and solutions, have been invented and produced in real life. This technology, called nano silver, produces silver in nanometers (one billionth of a meter). ) It is a small particle size of 0.000000001m, and nanoparticles of 1 gram of silver can make 10 particles.

Therefore, nano silver, which is nano-silver (Ag) in the form of super fine particles, is a new concept that is made by utilizing the excellent effects such as antibacterial deodorization and prolonging the preservation time of food among the many characteristics of silver.

 Since ancient times, silver has been recognized as a material that not only prevents germs but also disinfects both East and West. Currently, the extraction method of nano silver is used by adding silver (Ag 99.9%) to distilled water and generating low current at low temperature. The electrolyzed by using the + and-poles of each molecule, and then collect the silver (Ag 99.9%). In addition, it can be manufactured by physical methods such as liquid reduction or grinding. In order to obtain stable nano silver (NANO SILVER), many of the above electrolysis methods are used.

Silver ions are also used in general sterilization concept machines and disinfectants, and all silver products currently used are silver obtained by decomposition, and the addition amount is very small. The sterilization power of silver varies depending on the product, but a maximum of 99% can be obtained.

 Nano Silver is a fine particle of 3 to 5nm Silver, which acts directly on harmful bacteria, directly dissolves the cell membranes of harmful bacteria, and sterilizes by interfering with the electron transfer system of harmful bacteria, making it excellent and excellent antibacterial / bacterial activity (= 99.9%). (Virus size is about 10nm)

     Nano silver's main antimicrobial mechanism is to dissolve harmful bacteria cell membranes and interact with enzymes in cells to block the metabolism of nutrients, that is, the influx and discharge of nutrients, and to prevent the respiratory function and production of harmful bacteria. It destroys harmful bacteria by destroying them.

     In addition, nano silver has a long lasting antimicrobial / antibacterial function because it controls the harmful bacteria by continually release antimicrobial activity from the fine particles.

Therefore, nano silver is not resistant and nano silver has a surface reaction to have an effect, and kills 99% of all bacteria, and is particularly effective for general E. coli or food poisoning.

   “The larger the surface area, the smaller the nanoparticles are, the better the bactericidal and antimicrobial properties are, and based on the experimental data so far, E. coli, Staphylococcus aureus, Salmonella, Vibrio, Heterogeneous, Pneumococcal, Typhoid and resistant This strongest

MRSA (methicillin resistant Staphylococcus aureus) can be 99.9% antibacterial and bactericidal.

     Even if silver (Ag) is present in an ionic state or a metal state, it may be referred to as colloidal silver when it is present in a colloidal state by a solvent.

Nano silver also has the best antimicrobial activity.

 Nano silver is a very fine particle of pure silver unlike general chemical antibacterial and chlorine disinfectant, so it has excellent antimicrobial / microbial activity (99.9%) even at high temperature.It is nontoxic and non-irritating to the human body. It has been reported that you cannot live in contact with silver for more than 5 minutes.

The material consists of calcium hydroxide, radiopaque material urethral form, high molecular weight polydimethylglyoxane, peppermint oil and olive oil.

Looking at another preferred method of the temporary root canal filler of the present invention

 At the dentist, the surgeon must remove the enamel and dentin of the tooth, and then clean, sterilize, and remove organic components in the root canal that are nutrient sources for the bacteria including pulp and other decaying substances or bacteria.

Then, the temporary root canal filler formed into a kneading state is injected into the syringe 280. The nano silver is mixed with PNA in a content ratio ranging from 2 PPM to 999 PPM at a ratio of 0.01 to 20 wt. It is natural that the half (160) and the nano silver particles have a particle size of 5 to 300 nm and the fragrance is stirred at a ratio of 0.01 to 10% by weight.

In addition, after inserting the disposable injection tip into the injection port of the syringe 280, the injection tip is inserted into the root canal of the treatment target tooth, and the plunger of the syringe 280 is pushed to inject an appropriate amount of the root canal into which the temporary root canal filler is inserted. If the upper part is sealed with temporary restorative materials such as hydraulic cement, zinc oxide eugenol cement, carboxylate cement, and glass ionoma cement, the effects of calcium hydroxide can be sufficiently exhibited in the sterile state without infiltration of bacteria into the root canal.

 Nano antimicrobial material of the gutta percher cone or filler of the root canal filler 10 of the present invention is extremely preferred, and the amount of the compound 260 is preferably 0.01 to 20% by weight based on the total composition. Do.

 The effect of sterilization and odor removal is less than 0.01% by weight, and the increase in price and viscosity over 20% by weight is too clear for teeth in X-ray imaging, making it difficult for the human eye to read.

 In addition, the fragrance of the natural fragrance of the present application is aroma scent with a therapeutic effect and bactericidal effect is preferred, when used in 0.01% by weight or less can not expect the aroma function, 10% or more by the fragrance is too large sense of smell and dizziness I can feel it.

In the present invention, the root canal filler 20 containing the biocompatible material is composed of a powder and a solution.

First, the powder of the present invention is a curable root canal filler 20 containing one or two or more biocompatible materials and a biocompatible material composed of magnesium oxide and an X-ray (radiation) contrast agent.

  Referring to the components of the present invention with magnesium oxide and guiacol as the main curing agent 230 in detail.

   Biocompatible materials include calcium hydroxide, tricalcium phosphate, tetracalcium phosphate, eighth calcium phosphate, hydroxyapatite, collagen, demineralized freeze dried bone, indium foil, calcium sulfate, dentin and white granules, bone fragments , Titanium, chitosan, Teflon, tantalum and MTA. The composition ratio of the biocompatible material is preferably 10 to 40% by weight of the total temporary root canal filler 20, and hardening did not proceed smoothly when added at a ratio of 40% by weight or more.

On the other hand, magnesium oxide was added in 10 to 40% by weight to improve the fluidity of the material and after curing to form a substrate between the hydroxyapatite particles, and when the softening always forms a smooth dough and the main curing agent 230. Increasing the amount of magnesium oxide compared to hydroxyapatite increased the compressive strength of the mixture much.

 The radiographic contrast agent added at 10 to 10% by weight includes barium sulfate, bismuth bicarbonate, and iodine form. The solution used in the present invention consists of guai alcohol and rosin and includes one or two or more additives.

Zinc oxide added at 1 to 10% by weight has an aromatic odor, becomes black when exposed to light and air, and has antiseptic, antiseptic and local analgesic effects, and a calming effect of the wound surface in contact with the root canal filler 20 is expected. However, in the present invention, it is more preferable to inject nano silver ash in place of the radiocontrast barium sulfate, bismuth bicarbonate, and iodine form.

5 to 40% by weight of natural or synthetic rosin provides adhesion and smoothness when mixing cement, and depending on the amount, the curing time and the periphyllal tissue are affected, and the addition of rosin makes the mixture cohesive and reasonable curing time. In the case of solidification and poor melting, the higher alkalinity actually delayed the cement hardening time within the experimental time range.

One or two or more plasticizers in a solution of 1 to 20% by weight are used to control the viscosity of the root canal filler 20, including volatile organic solvents, glycerin and related compounds, and nonvolatile materials of low molecular weight paraffinic hydrocarbons. And oxides and hydroxides containing calcium, aluminum, zinc, potassium, and sodium ions; volatile organic solvents include acetone, ethanol, isopropyl alcohol, ethyl oxide, orange oil; glycerin and related compounds include ethylene glycol, propylene glycol, Glycerin, polyethylene glycol, polysorbate.

Next, the pigment put in order to colorize the thickness or length of the Gatpachacon, the temporary root canal filler 20, is 1 to 20% by weight of the curing agent 230 or flocculant 0.01 to promote the coagulation It is preferable that the weight ratio of 1 to 20% by weight is added to the wax, which is added in an amount of 5% by weight to 5% and melts during thermal heating.
