Abstract
Object: researching the combination of endodontic and surgical treatment of a tooth with developing dens invaginatus pathology. Materials and methods. X-ray diagnostics were performed with the Veraview X800 Morita. Irrigation with sodium hypochlorite solution 5.25 % with additional ultrasound treatmentabd 17 % EDTA solution were used for drug treatment of invagination and the main channel. The root canal and invagination, due to a non-standard structure, were handled by VDW hand tools combined with the Aurum BLUE (Meta Biomed) machine tool. Constant obturation was performed by the method of vertical compaction «Siller-AN plus». During the surgical stage, Langer (Hu-Friedy) periodontal curettes, CL 8 (Hu-Friedy) curettage spoon, 141-004-31W Oval Spoon Excavator (Hu-Friedy) were used; access to the focus was formed using a piezo surgical spherical nozzle (CE 1, Piezotome Solo (Satelec, Akteon). 4583 Kohler needle holder was used for suturing, suture material – polypropylene 5.0. The bone defect was filled with xenogenic material BIO GEN cancellous size 2/3 mm, 2.0 (Biotek), the barrier membrane – BIOCOLLAGEN (Biotek), the periodontal defect was filled with BIO GEN mix (Biotek). Key words: dens invaginatus, tooth in tooth, endodontic treatment, bone augmentation, apical surgery.
