The aim of the present study was to describe a case of endodontic retreatment in a mandibular molar with symptomatic apical periodontitis.
The objectives of endodontic treatment are the prevention and treatment of apical periodontitis. A maximum amount of organic, live, or decomposed substrate and microorganisms must be eliminated to achieve the root canal system disinfection. (1) It is essential for the success of the endodontic treatment that all steps are performed correctly, and an error in one of them can lead to failure.
The final goal of endodontic therapy is to obtain an endodontic obturation that allows tridimensional sealing of the root canal system, using a nonirritant material to support periapical healing. Currently, endodontic sealers with bioactivity deserve special mention, that is, the ability to stimulate the repair and deposition of mineralized tissue. Among these sealers, it is possible to highlight BioRoot®RCS, developed
by Septodont (Saint-Maur-des-Fossés, France), based on calcium silicate and which presents zirconium oxide as a radiopacifying agent. Its components exhibit high purity and presentation in powder-liquid form. The development of these new sealers, whose physical-chemical properties improve in the presence of moisture and involve chemical adhesion to dentin (2,3) helped to popularize the single-cone technique. This technique, with greater taper gutta-percha cones, made filling the root canals a faster and simpler procedure, while minimizing the forces applied to the root canal walls by the spreaders, without decreasing the quality of the apical sealing. (4) The reported results are similar to the classic techniques of lateral compaction and vertical compaction, either in relation to the percentage of voids volume (5) or to the depth of penetration of sealer into the dentinal tubules. (6) The obturation technique with a single cone basically consists of the insertion of a single cone in the root canal, usually of the same diameter and taper as the last instrument used for the apical preparation and thus adapted to the anatomical configuration of the prepared canal, associated with an endodontic sealer.
Therefore, the aim of this report was to present the diagnosis and endodontic management of a retreatment clinical case of permanent mandibular first molar with apical periodontitis, by using BioRoot® RCS sealer and a single-cone technique for the root canal system obturation.
