The root canal of the tooth is an anatomical space inside the root. This natural space within the crown portion of the tooth consists of a pulp chamber that is connected by one or more of the main channels, as well as more complex anatomical branches that can connect the root canals to each other or to the root surface of the tooth.  Root canal treatment is needed if the large cavity has damaged the root or there is an injury in the root or it is infected.



Root Canal Treatment:

The most common causes of damage or death of pulp are the presence of a crack or a deep carious cavity in the tooth. In dental practice, in the process of endodontic treatment of acute purulent and chronic pulpitis, ​mechanical treatment of the root canal system of the tooth is performed. This is called depilation and involves the removal of vessels and nerve. This is followed by sealing (hermetic obturation) of the canal (s). This type of root canal treatment is performed in two versions:


  • Devital Extirpation –Removal of the neurovascular bundle is performed for 2 visits. At first, a message is created with the pulp chamber of the tooth, into which a devitalizing paste is applied.
  • Vital Extirpation –In the absence of pronounced inflammatory phenomena passing into the periodontium, removal of the vascular-neural bundle and its obstruction is performed under anesthesia in one visit. The drug is left in the canal for the removal of inflammation. In the process of treatment, at least 2 X-rays must be taken: the first – before the start of treatment (to assess the length and structure of the channels), and the second – after (to assess the quality of canal filling).


Challenges of RthemCanal Treatment and How Does a Dentist Deal with Them:

Planning, as well as solving the tasks of forming, cleaning and obturation of root canals during endodontic treatment are fraught with real and potential dangers associated with the complexity of the anatomical structure of the root canal system, as well as the technical features of their instrumental processing, disinfection, and sealing. In the process of endodontic treatment and after filling the root canals of the tooth, certain problems may arise:


  • Impassability of the root canal, associated with the peculiarities of the anatomical structure of the tooth (crimp, branched);
  • Presence of particularly persistent pathogens, resistant to the action of antiseptics, or re-penetrated through the dentinal tubules;
  • Apical periodontitis; involving infection caused by chemicals, trauma, etc.
  • Iatrogenic errors, for example, root perforation.
  • Fracture of the root of the tooth.


The inflammatory process will invariably and systematically destroy the layers of the tooth, provoking unbearable pain and unpleasant consequences, the main impact of which can be the loss of the tooth. In addition, in some cases, it may be necessary to reset the root or re-seal the root canals of the tooth. In this case, the main task of the dentist is to fill the root canal with the filling material as much as possible, preventing the possible occurrence of inflammation in the future. For this purpose, certain filling compounds are widely used, with antiseptics added. To achieve the goal in modern realities, mechanical, as well as medical, methods are often practiced. The mechanical version of root canal treatment can be carried out with the help of appropriate tools and modern equipment, up to endodontic motors and so on. In the process, drugs made based on organic solvents, which can change the structure of the seal, are used.


It can be concluded that it very important to go to a highly experienced dentist who has expertise in root canal treatment.
