With modern endodontic treatment, it is possible to save a tooth in which the nerve, commonly referred to as the pulp, is diseased, e.g. by infection or inflammation due to tooth decay. By means of microscopic root canal treatment even a tooth whose nerve is irreversibly damaged can be preserved and the bone can return to normal.
Teeth may have one to three roots with complex anatomy and canals, which contain the pulp. Some of these canals are as thin as a hair. For root canal treatment to be successful it is important to detect and treat all root canals. This is not possible with conventional and quick root canal procedure.
