How many channels in the teeth of the upper and lower jaw, on which the number of channels depends

It is only possible to determine the number of channels in the tooth using an X-ray.Of course, their number depends on where the tooth is located - with more chewing load on the teeth in the back of the jaws and the holding system is stronger, respectively, they are larger, have more roots and channels.However, this is a variable indicator, and it does not mean that the upper or lower incisors have only one channel, it all depends on the individual characteristics of the jaw structure of each person.Therefore, how many channels in a diseased tooth require a filling, will be able to determine the dentist at an autopsy or using an X-ray.

Interest calculation

Due to the fact that each person is individual and there are no clear rules and rules for determining how many channels in the teeth, in dentistry data on this issue are given in percentage terms.Initially, it is repulsed because the same teeth of the upper and lower jaw are very different from each other.If the first three upper incisors have only one channel in almost a hundred percent of the cases, then with the same teeth of the lower jaw everything is much more complicated, and they have approximately the

the following percentage:

• In the first cutter, only one channel is usually70% of the total statistics and only 30% of them may be two;
• The second tooth in practically equal proportions can have both one and two channels, more precisely - the ratio of 56% to 44%;
• The third incisor of the lower jaw almost always has only one channel and only 6% of cases can have two.

The premolars have a larger structure, they already have more pressure and load, so it's logical to assume that there are more channels in the tooth, but not everything is that simple.For example, in the fourth tooth of the upper jaw, only is valid. 9% of the teeth have one channel, in 6% of cases, there may be even three, but the rest are often found with two.But the next premolar( the fifth tooth) which seems to have an even stronger load usually has one channel and only in some cases more( of them only 1% fall on three branches).

In this case, the situation on the lower jaw is quite different: the first and second premolars do not generally have three-channel, and most often have only one channel( 74% - four and 89% - five) and only 26% for four and 11% forFive - two.

Molars are already larger and the number of channels they have is increasing.The jaws of the upper jaw are equally likely to have both three and four branches.On the lower jaw sometimes there can be a two-channel tooth( usually not more often than in 6% of cases), but more often these are three channels( 65%) and sometimes four.

The rear molars usually have the following relationship:

• Upper Seven: 70 to 30% three and four channels;
• Lower seven: 13 to 77% two and three channels.

Tooth of wisdom

Eight or the wisdom tooth is quite unique and does not fall under standards and statistics.The upper one can have a completely different structure with channels from one to five.The lower eight is the most common three-channel, however, often during autopsy during treatment, additional branches can be found.

Among other things, the wisdom tooth differs from others in that its channels are rarely of the right form, often very curved and with a narrow stroke, which greatly complicates their treatment and sealing.

Wrong opinion

Since the tooth consists of roots and the pre-crown part, it is sometimes mistaken that canal in the teeth as much as the roots of .This is far from the case, because the channels quite often branch off and bifurcate about the pulp.Moreover, in one root, several channels can run parallel to each other.There are also cases of their bifurcation in apex, which means that one root has two apexes and this, of course, complicates the work of doctors when filling such teeth.

Given all the features of the individual structure of the teeth, dentists need to be very careful in the treatment and sealing, so as not to miss any branch.After all, sometimes without an X-ray, it is very difficult even to reveal how many channels in the teeth at the autopsy.

Treatment

The development of modern medicine and dentistry in particular, today allows more and more often to save those sick teeth that had to be removed yesterday because of the impossibility of treatment. The procedure for treating the root canals of the in the teeth is quite complicated in itself, because they are filled with a soft tissue - a pulp that contains a large number of nerve endings, blood vessels and other connective tissues.Today, this is a separate section of dentistry - endodontics, the development of which allows to improve the state of human teeth and cure even complex problems in more than 80% of cases, while retaining the tooth itself.

The objectives of this treatment are:

• Removal of an evolving infection within the root system;
• Prevent pulp decay or its removal;
• Removal of infection infected with dentin;
• Prepare the canal for filling( giving it the desired shape);
• Enhance the effect of the effects of drugs.

The complexity of such a root system treatment is that the dentist rather finds it difficult to reach the sick channels and monitor the procedure.After all, if you do not remove even the microscopic part of the infection, it will be able to develop again in a while.

One of the main indicators for such treatment is the inflammatory process, which leads to the destruction of soft pulp tissues inside the canals.Most often this leads to a variety of diseases such as caries and pulpitis, but the treatment of canals may be needed and with periodontitis.

The first symptoms of the need for such treatment are pain in the tooth or swelling of the gums.However, it should be borne in mind that in the case of the transition of the disease to the chronic stage, the pain may not be observed, but the disease develops and eventually leads to tooth loss.That is why it is so important to undergo a regular preventive check with a dentist.

The process and stages of treatment of

channels The root canal treatment process has the clear sequence of steps:

1. Initially, it is necessary to conduct the correct diagnosis of the disease.In difficult cases, the dentist sends the patient to the X-ray.
2. After this, the doctor conducts the necessary preparatory procedures for the oral cavity to treat.
3. Treatment of canals is a rather painful procedure, so the tooth must necessarily be anesthetized by the introduction of anesthesia( usually in the gum near the aching tooth).
4. After this, a complete aseptic of all instruments is performed and the patient tooth is separated from the rest with a special rubber film( kaffedrama).
5. Further, the diseased tooth is opened with the help of a drill, ensuring maximum access to diseased canals, after which their initial cleaning is carried out, the infected pulp is removed and the channels are treated in parallel with special medications.
6. After they are dried and sealed with special materials.

If the doctor has any doubts( usually this happens with an uncomfortable positioning of the tooth and difficult access to the instruments) - he puts the temporary seal , then sends the patient to the X-ray, from which he checks whether the infection is allRemoved and all channels cleaned.A permanent seal is then inserted about two weeks after this.

This whole procedure, of course, is not very pleasant, but it allows you to save the tooth.Its duration depends on the location of the tooth, the number of channels in it, the complexity of the developed infection and usually takes thirty minutes to one hour.And success depends on the professionalism of the doctor and the quality of his work, since it is necessary to remove all the affected pulp from the canals without leaving a single drop of infection, otherwise it can develop again and tightly seal the tooth, so that nothing could fall into the cleared cavity.

Prevention after treatment

After the treatment of the root system for some time, should avoid loading the on the cured tooth, moreover, one should not eat before two hours after the therapy, otherwise the not completely frozen fill may simply fall out.However, the same can occur when the doctor uses poor-quality drugs or improper treatment( for example, dried or not dried channels before sealing).

Also after sealing for a while the tooth( up to several days) can give pain when pressed or just whining, cause discomfort, have increased sensitivity.Usually this is a normal condition, if the pain is severe, you can take painkillers.If the pain does not go away after a certain time, it can also be an indicator of poor treatment( insufficient cleaning of infection or contaminated pulp, leaky sealing, use of poor-quality medicines or materials).

Sometimes there are cases of of allergic reactions , which is also accompanied by persistent pain, sometimes itching and rash on the body.It can be caused by a reaction to a medicine or material that was used for a seal.In this case, it must necessarily be replaced with another one, which will not cause allergies.

In all these situations, it is absolutely necessary to consult a doctor for the second inspection and preventive maintenance of teeth in the shortest possible time, which would reveal the cause of the abnormality.
