The use of modern technologies and the machine system Reciproc (VDW) during the revision of the root canals of a tooth with apical periodontitis: a case report

   Endodontic retreatment in most cases is indicated with the development of apical periodontitis in teeth with previously treated root canals. This treatment is complicated by the fact that the root canals can be lined with any material: guttapercha pins, paste, cement, anchor and fiberglass pins, resorcinol-formalin paste, fragments of tools can be located in the channels at any level and root canal transportation can occur. The choice of endodontic treatment or tooth extraction is always before dentists. The availability of modern machine files, ultrasound attachments, filling materials and X–ray examinations in the assortment of doctors makes it much easier for dentists and therapists to conduct endodontic treatment and improves its quality. This article presents a clinical case of repeated endodontic treatment of a 2.6 tooth with apical periodontitis and a clinical picture of chronic sinusitis. The article shows the main stages of treatment, the results of X-ray examinations, microbiological examination of the root canal biofilm before and after mechanical treatment with the Reciproc endosystem and long-term results, which will help practicing dentists during root canal revision.
