Re-treatment of duct (reendo)

Repeated root canal treatment , commonly called "re-endo", is undertaken in a situation where the tooth gives clinical symptoms in the form of a pain reaction or periapical change visible on the X-ray. Revision of endodontic treatment is usually necessary in teeth whose canals have not been filled to the apex, i.e. to the full length, or one of the canals has been omitted. Re-root canal treatment is performed using a dental microscope. In the age of 21st century dentistry and the possibility of working in enlargement, the failure of the dental canal happens very rarely. Previously, when x-rays were not so common, there was more often an underfilling of channels, therefore a large group of patients are patients treated during this period. Re-treatment of canal is more complicated than primary. In its course, complications occur more often. Due to the greater difficulty, the treatment is performed under a dental microscope. The whole procedure involves removing the old, leaky filling from the channel, the correct development of the peak section. Further treatment is no different from classical canal treatment. Faqs

• Should every tooth with an unfilled canal be re-treated? The human body has many defense mechanisms. In the case of teeth, sometimes the obliteration (overgrowth) of the channel vertex may occur, preventing the development of bacteria. Such a mechanism is very desirable and despite the incorrect filling of the channels allows the doctor to give up repeated endodontic treatment. The clinical image to stop re-treatment of duct is the absence of pain ailments, as well as healthy tissues around the root in the X-ray photo.
• When should I opt for re-endodontic treatment? The decision to revise root canal treatment is made when there is inflammation in the area of the root apex. Usually, patients complain of pain, but sometimes an inflammatory outbreak is only visible in the x-ray photo and develops asymptomatic. If the tooth has been qualified for prosthetic treatment with a bridge or crown, all unfilled channels should be recured, even if they do not give adverse symptoms.
• Why is root canal treatment carried out under a dental microscope? Re-root canal treatment is always much more difficult than the first treatment attempt. A dentist working under a microscope can find more easily the causes of early treatment failure such as: left blank channels in the tooth, steps in canals blocking the way for endodontic tools, fragments of broken tools or non-road channels. This significantly increases the chance of proper duct cure of such a tooth and no need for re-interventions in the future.
• Is it possible to root canal a tooth under a crown or bridge? Yes, however, gaining access to improperly healed canals often requires a breach of the crown or bridge. When deciding on reconstruction with a permanent prosthetic restoration (crown, bridge), a solid foundation for this type of reconstruction should be created, and only proper endodontic treatment (usually treatment under a microscope) will ensure lasting effects and joy of a healthy smile.
