What is a Root Canal?

A root canal is that part of the tooth in which the dental “nerve”, or pulp, is located. A“living” tooth differs from a “dead” tooth precisely by the presence of pulp. This tooth tissue is located both in the tooth crown and in its root, and the processes of the pulp penetrate the dentin through microscopic channels, reaching the enamel. Pulp nourishes dentin, participates in its growth, protects other soft tissues of the dentition from infection.

Root canal treatment

Why is root canal treatment such an important procedure?

Inside each tooth, there is an internal cavity called the pulp chamber. It is associated with root canals - cavities inside the roots of a tooth. A different number of channels corresponds to a different group of teeth. Therefore, depending on which group the tooth belongs to, depends on the number of its root canals. Typically, they are between one and three.

The root canal of a tooth is a thin elongated hole located along the axis of the root. The entrance to the root canal is called the apical opening (from the apex - the apex), it is located at the end of the root. Through this hole, blood supply and innervation of the tooth is carried out with the help of a nerve, more precisely, the neurovascular bundle, which enters the root through the apical opening. Often, micro branches resembling the crown of a tree depart from the main canal of the tooth. In the process of root canal treatment, this must be taken into account.


Why is it necessary to fill the canals of the tooth?

It is necessary to understand why, after removing the nerves from the tooth, it is necessary to seal the channels. The hollow root canal of the tooth is fertile ground for the development of various infections. In an unsealed canal, optimal conditions are formed for the propagation of pathogenic microorganisms, which subsequently cause inflammation of the peri-root tissues - periodontitis. Such tooth risks being removed. To prevent this, the channel should be hermetically and tightly sealed.

Root canal filling

The success of root canal filling is largely determined by the quality of the previous endodontic procedures, and mainly determines the outcome of the treatment.

The main requirement of this stage is the reliability of root canal sealing. Before filling, the channels are dried with paper pins.

To fill the root canals, gutta-percha and paste are used. Gutta-percha is a rubber material that is produced in the form of cones; the size and shape of gutta-percha correspond to the shape and size of the files by which root canals are cleaned.


Gutta-percha pins

Gutta-percha cones are pasted and inserted into the root canals of the tooth. To obtain good sealing, a few more cones are introduced into the root canals.


Paste for filling canals

After filling the root canals, the dentist puts a temporary seal on the hole that was made to reach the root canal.


Root canal filling

The canal should be sealed to the apex and without voids and defects.

After all this, the next visit is scheduled, during which the dentist puts a permanent seal.


Root canal treatment methods.

Surgical endodontics is performed with full anesthesia. Removing a nerve is a very painful procedure. Access to the pulp and the mouth of the root canals is carried out by drilling holes in the tooth. After the pulp chamber and root canals are opened, nerves can be removed using a special tool - a pulp extractor. Then you need to thoroughly process the channels. This is a very important and sensitive procedure.

  • Before the root canal is sealed, it is necessary to conduct its high-quality antiseptic treatment with antiseptic drugs. If the treatment is not done thoroughly enough, complications are possible in the future - inflammation of the peri-root tissues - periodontitis.
  • The second stage of channel processing is instrumental expansion. Root canals are most often very narrow. Therefore, it is almost impossible to seal it qualitatively without mechanical expansion. To expand the root canal, special tools are used - micro files of various diameters.
  • The final stage of root canal treatment is filling. The channel must be sealed tightly The fate of the tooth will depend on how well the filling is performed.

What does quality root canal filling imply?

  • The canal must be filled with filling material along its entire length to the apical opening.
  • There should not be a single air cavity in the sealed channel.
  • The filling material must be of good quality, it must not change its physical and chemical properties for a long time.
  • It is necessary to check whether the patient has an allergic reaction to the filling material.
  • All micro-branches from the root canal must also be filled with filling material.

For canal filling, a preparation based on processed gutta-percha, a substance obtained from plant components, is used.

Consider the methods of root canal filling using gutta-percha:

  • Filling with gutta-percha pins (cold gutta-percha), otherwise, this method is called lateral condensation.
  • Vertical condensation - a way to seal heated gutta-percha
  • Filling with thermal - heated gutta-percha on the carrier.

All these methods have both advantages and disadvantages, in general, they give approximately one result. But the second and third methods are more optimal since the heated gutta-percha is more plastic, which allows filling not only the channel without pores and air cavities but also microchannels. And this is the key to further remission and the absence of complications. But the successful outcome of treatment depends not only on the application of a particular technology but also, first of all, on the qualifications and skills of a specialist who applies this or that technique.
