Abstract:
The goal of endodontic treatment is to debride and clear the root canal
system of infected pulp tissue so that the canal space can be shaped and
prepared to be filled with an inert material, thereby preventing or minimizing any chance of reinfection. However, failure occurs when endodontic
treatment does not meet clinical standards and principles. Two approaches
have been proposed to solve this problem. In the first approach, residual
bacteria are eliminated or prevented from repopulating the canal system
by inserting a dressing into the root canal, in an additional visit, generally
falling into the following categories: phenolic derivatives (eugenol, paramonochlorophenol camphorate, phenol camphorate, metacresyl acetate ,
creosote from beech wood), aldehydes (formocresol), halogens (potassium
iodide), calcium hydroxide, antibiotics or other combinations. The decision on the treatment tactics remains at the choice of the dentist, depending
on the clinical condition, the general condition of the patient, the technical
possibilities and the materials at his disposal, as well as his experience.
