Running can lead to falls, playing basketball can sprain an ankle, eating steamed bread without diluted rice can choke you to death, and swimming in wild rivers can drown dozens every year! There are also hundreds of thousands of traffic accidents every year, so why are there still people swimming? And there are still people driving?
That's because there is a demand, demand if it is just needed, even if there is a risk, but as long as the risk is controllable, we can still accept, or can do.
Why do you need a root canal? That's because the tooth has been broken to the pulp, hurt the root of the tooth, do not do root canal treatment, the tooth will be painful, will be repeated inflammation. Is there any other way to keep the tooth from hurting and the root from getting inflamed other than root canal treatment? Of course there is. Getting the tooth extracted makes it painless!
Root canal treatment is the last line of defense for retaining teeth. If you have a bad tooth that has been dragging on for years, you don't fill it because it doesn't hurt, and as a result, shallow caries become deep caries, and deep caries develops into pulpitis, and it's not until one day, when the tooth starts to hurt, that you remember that you still have a bad tooth. ......
The tooth develops To the point of needing root canal treatment, in fact, it is not far from the extraction of the tooth, if you miss the best time for root canal treatment, or root canal treatment failed, then the tooth will have to be extracted.
That is to say, root canal treatment, is the tooth's life-saving straw, do the root canal treatment, successful, the tooth even saved, and then do a ceramic crown to strengthen, but also a few years of life.
If you don't do a root canal, or root canal treatment failed, the tooth can only be extracted, then, again, there will be netizens on the Internet to ask me, extraction of teeth pain? The first thing you need to do is to get a good deal on the price of the product, and then you have to pay for it.
As long as you don't want to pull the tooth, then root canal treatment should still be done, and I'll talk about the risks that you may face when doing root canal treatment and how to avoid them.
(1), the risk of root canal treatment instruments
* hot glue stick
When the pulp is inflamed, often the affected tooth on the same side of the maxillary and mandibular teeth will be painful, in order to determine the location of the affected tooth and the state of the pulp, the doctor is often clinically hot and cold diagnostic of our teeth, the hot diagnostic is a stick-shaped dental glue stick, a section of it with alcohol, a piece of the tooth, and a piece of the tooth, a piece of the tooth, a piece of the tooth, and a piece of the tooth, the tooth, the tooth, and a piece of the tooth. The hot diagnosis is to use a stick-shaped dental adhesive stick, a section of which is heated with an alcohol lamp and then placed on the neck of the tooth coated with petroleum jelly.
If there is inflammation in the pulp of our teeth, it is very sensitive to changes in temperature, and usually a painful reaction occurs after about 2 seconds of contact between the hot stick and the tooth. (Healthy teeth and dead pulp teeth have no obvious feeling or feel the same as the control teeth)
When using the hot glue stick, the operator must remember not to bake the hot glue stick is too soft (to not smoke shall prevail), too soft glue stick will be bent out of shape, or even into a molten state, at this time, the glue stick is very easy to scald the mouth and lips.
As a patient who is undergoing dental heat treatment, when the teeth are in pain, we must remember not to move, so as not to be scalded, and the right thing to do at this time is to raise your left hand to signal the doctor, and the doctor will immediately terminate the operation after seeing it.
* crack drill
crack drill open pulp, in order to be safe, the needle should be as parallel as possible and the long axis of the tooth, and the diameter of the crown side of the open pulp hole slightly enlarged. If a crack drill, drilling directly down from top to bottom, the pulp opening hole is too small, or the angle is not right, as long as we have a slight swing of the head, it will lead to crack drill breakage!
If the drill breaks inside the teeth, it's not a big problem, just take it out. What's scary is that the high-speed rotating drill suddenly breaks, and the drill bit flies around in the mouth like shrapnel, which is scary, and if you accidentally inhale it into your lungs ........ Just thinking about it makes my head spin!
Therefore, when the doctor drills our teeth, the head must not swing freely, if the pain is uncomfortable, raise your left hand to signal the doctor to stop the operation can be.
* Pulp needle
The metal pulp needle with barbs is a powerful tool for removing the pulp, but there are not only teeth in the mouth, but also the tongue, gums and other soft tissues, so you must be careful when you use the pulp needle, have you ever experienced the kind of full of barbed pulp needle stuck in the lips, pulling out all the despair?
*Spiral conveying needle
The spiral conveying needle is an auxiliary tool to deliver calcium hydroxide or root filling paste into the root canal, connect the spiral conveying needle to the slow speed curved machine, reduce the speed, and then step on the foot switch, then you can use it, because the spiral conveying needle is very soft, when the speed is too high, it will increase the probability of breaking the instrument.
When using the screw conveyor needle, one must be wary of the cotton balls on the buccolingual side of the affected teeth that are used to insulate the moisture, which can easily become entangled in the rotating conveyor needle, leading to instrument breakage or loss of control of the cotton balls that insulate the moisture, which can fly around in the mouth.
An out-of-control piece of cotton ball is worse than a broken needle, and cotton balls swallowed and inhaled by mistake can lead to very scary things!
*Root canal files
Root canal files are handled metal needles with a cutting edge on the working end, used to remove pathogenic material from the walls of the root canals, and to widen and shape the root canals.
Root canal files are very sharp and need to be extended into our mouths to be used, so we need to cooperate with the doctor and try to avoid being accidentally injured (stabbed).
A root canal file is a very small, thin, metal needle with a handle that the doctor uses to hold on to, but if the doctor's hand slips because of saliva, the file can fall inside our mouth.
If the doctor loses control of the file, there is a high likelihood that the instrument will be swallowed. Root canal files that we swallow can cut our esophagus, stomach, or even become lodged in the soft tissues of the pathway, and if they cannot be removed on their own, they need to be removed using a medical intervention.
Root canal files are swallowed into the stomach is a small probability of events, we try not to go to the dentist to do root canal treatment when they have a cold or in bad shape, if the root canal instrument accidentally fell into the mouth, do not panic, sit up, bow your head, cough and spit out or let the doctor take out.
In fact, the root canal file is swallowed into the stomach is not the most horrible thing, the most horrible is the root canal instrument or cotton ball sucked into the lungs, which is an accident that will kill people!!!!
Therefore, people with colds and coughs, or uncooperative children, are not recommended to carry out dental treatment without protection, so as to avoid the occurrence of medical accidents caused by the accidental swallowing and aspiration of instruments and cotton balls.
* X-ray dental
Dental X-ray radiation dose is very small, the radiation dose of the root tip film is even smaller, but the dose is small does not mean no, so the pregnant lady if not emergency, try not to shoot X-ray film, especially in the first trimester of pregnancy, the early stage of the development of the fetus is very sensitive to radiation, the radiation received during pregnancy may lead to fetal malformation.
* Electronic root scanner
Electronic root scanner is a precision instrument to measure the length of the root canal according to the principle of constant resistance between the periodontal membrane and the oral mucosa, the instrument itself is not dangerous, but because the electronic root scanner is an electronic product, so the installation of pacemakers or the body of the patient has implanted other electronic medical devices, you need to explain to the doctor in advance to assess the risk before operation. The risk is assessed in advance and then operated.
(2) Risks of Endodontics Drugs
* Numbing
When endodontitis is in acute attack, the tooth is in pain when it is hot or cold, and it is difficult to carry out the next operation without the use of anesthesia, and it is necessary to inform the doctor about your own allergy history before the injection of anesthesia. allergy history.
Routine use of local anesthetic for lidocaine and ativan, injection of anesthetic, first, to the doctor to explain their own history of drug allergies, and second, try not to inject anesthetic on an empty stomach, so as not to increase the chances of fainting due to hypoglycemia, if the injection of anesthesia, dizziness and panic and other symptoms of discomfort, you have to tell the doctor in a timely manner.
Doctors in the injection of anesthetic, must remember the words "back to no blood", syringe back to no blood can be injected, if careless, the anesthetic injection into the blood vessels, may lead to anesthesia poisoning occurs.
* inactivator
Now dental commonly used endodontic inactivator, the composition of trimethylaldehyde (trimethyl) based on the sealing time of 7-14 days, its toxicity is weaker than arsenic, the role of the slow safe.
Another type of arsenic-containing inactivator, the general sealing time for 24-48 hours, because arsenic agent toxicity, no self-limiting, easy to lead to chemical periapical inflammation, so the clinic has been rarely used.
When our teeth are sealed with nerve-killing drugs, try not to bite with the affected side, so as not to dislodge the temporary sealing material on the teeth, leading to leakage of inactivation agent, which in turn burns the gums. During the sealing period, if the temporary sealing material on the tooth falls off, you should promptly return to the doctor for treatment.
*Root canal disinfection drug FC
FC's Chinese name is formaldehyde cresol, which has a strong bactericidal effect. It is often used to disinfect infected root canals, such as pulp necrosis, etc. FC can cause coagulation and necrosis of the pulp tissue in chronic pulpitis, so FC is also commonly used in dry pulp surgery to disinfect the pulp chamber before filling "medicated bath".
It has been pointed out in the literature that formaldehyde drugs have a semi-antigenic effect and sensitization, so allergic people should be careful, and some literature has even raised the issue of the carcinogenicity of FC (this is doubtful, can not be set aside the dose).
FC has a corrosive effect on mucous membranes, so when using it, do not let the cotton ball stained with FC touch the mucous membranes of the patient's lips and mouth, so as to avoid chemical burns (very painful).
Nowadays, there are better, safer, and less irritating root canal disinfectants available on the market, so FC is starting to be phased out as a root canal disinfectant (trend).
*Root canal rinsing solution
Many people may have this concern: what if the root canal rinsing solution is accidentally swallowed? Is it toxic?
First of all, the answer, the drugs used in the mouth, are relatively safe drugs, if you drink a whole bottle, you may go to the hospital, if you just accidentally swallowed a small mouthful, it should not be a big problem, but it is best not to drink, after all, the taste is not good.
Commonly used root canal rinsing solutions include sodium hypochlorite, chlorhexidine, EDTA, saline, hydrogen peroxide (use with caution), etc. Chlorine-containing rinsing solutions are now the clinically preferred choice,.
Root canal rinsing solution first, pay attention to the concentration, high concentration, mucosal irritation and toxicity of the rinsing solution must be on the rubber stamp, pay attention to the edge of the rubber stamp leakage problems.
Secondly, the foaming class (hydrogen peroxide) rinsing solution, in the rinsing of the root canal will produce bubbles, may be pushed to the root canal debris deep into the root canal branches, so that the back of the rinsing material or root canal file difficult to enter, there is also the use of this type of rinsing solution led to subcutaneous emphysema cases, so in the use of this type of rinsing solution, to grasp the indications, fine curved root canal used with caution.
3. Cross-infection in root canal treatment.
Because some high-value root canal instruments are autoclaved and reused, disinfection is extra important when using non-disposable root canal instruments!
Instruments such as high-speed emery turning needles for pulp opening, tungsten turning needles, metal lip hooks for endodontics, K-files, C-files, H-files for root canal dilation, machine dilation needles, screw conveyors, and pulp extracting needles (mostly disposable) are more expensive, and as they are disposable, counting consumables on the patient's head can add hundreds to thousands of dollars to the cost of a root canal, which is already not cheap.
We don't have to worry too much about the reuse of high-value endodontic instruments. These instruments, like the handle of a scalpel in a hospital, or the tip of an ultrasonic scaler, or the tip of an ultrasonic scalpel, can be used without worrying as long as they are sterilized at high temperatures and high pressures in accordance with a standard procedure.
However, poor environmental hygiene, and even a separate disinfection room are not even small street clinics, or market stalls in front of the door of the jungle doctor, see them, we have to hide far away, do not want to take advantage of the cheap, to take the risk.
Of course, it is not the size of the quality, not all the street clinics are not qualified health, just in terms of disinfection, the smaller the size of the clinic, the more likely to hit the mine, so unless it is more familiar with the small clinic, or meet the need to see the blood of the operation, try to go to the disinfection of the qualified regular hospital or chain of clinics.
Supplementary sterilized instrument packaging:
4, root canal treatment failure how to
Root canal treatment encountered the bottom of the pulp chamber bottom penetration, the side of the root canal wall penetration, the root canal filling underfill, overfill, missing root canal, broken needle, root canal fracture ...... and so on. The root canals may fail.
(The yellow line is the root of the tooth, and the white line is the root filling)
All treatments do not have a 100% success rate, and with the advancement of endodontic theories and technology, the long-term success rate of root canal treatment is only infinitely close to 100%.
Therefore, even if we have the above situation during root canal treatment, don't be too afraid, please trust your dentist, they will try to avoid the above situation, once the above situation occurs, there are still certain remedies can be used.
If the root canal is separated from the instrument (broken needle), if the separated instrument does not affect the operation and root filling, and has no effect on the surrounding tissues, it can be left in place. If the broken needle affects the operation, depending on the location of the broken needle, the separated instrument can be removed as much as possible, and if the broken needle can not be removed, you can try to unclog it from the bypass route and continue to complete the root canal treatment.
If the broken needle is beyond the root tip, depending on the situation, you can also carry out apical surgery, the isolated tooth to improve the root canal after reimplantation and other means ...... other cases such as bottom penetration side penetration, depending on the size of the perforation, there are also appropriate remedies.
5, root canal treatment can cause cancer?
I searched around the Internet, saying that root canal treatment can cause cancer, is a very old article, to be honest, that article is not written rigorously, a lot of loopholes, examples and experiments are not supported by the data, only that the root canal is not good, the examples are also someone who got sick after the root canal treatment .....
So my subjective opinion is that root canals don't induce cancer, and since I haven't seen any recent articles on the subject, is there a link between root canals and cancer? I'm limited to space, so I'll write a separate post next time to talk about this in more detail.
What I wrote at the end of the article:
This column is mainly to popularize the knowledge related to root canal treatment, but some of the knowledge in the root canal treatment, if it is the first time to contact, may be read in the cloud, so this column will be interspersed with some of the basic knowledge of oral health in the previous articles for everyone to learn. This column will therefore intersperse some of the basics of oral health in the previous articles for you to learn.
Between each person's own situation and the ability to understand the text of the different, the information in this column is only used as a reference, not as the basis for diagnosis of the disease, do not try to give yourself or your family members to "see the doctor" through these words! The first thing you need to do is to go to your regular dentist in a timely manner.
Because even professional doctors, after learning a lot of medical knowledge, need a lot of clinical experience to improve their ability to identify diseases, so want to go through a few short articles to diagnose their own or their families' diseases, it is not safe and reasonable.
