PARTICULAR FEATURES OF ROOT CANAL FILLING IN TEETH WITH RESORBED APICAL OPENING NEAR THE MANDIBULAR CANAL

Abstract

When filling root canals of teeth with apical resorption near the mandibular canal, there is a risk that the material will go beyond the apex into the region of mandibular canal, which can lead to serious damage to the innervation of this area. In most cases, modern approaches and technologies in endodontics allow to achieve the formation of dentinal plug in the resorption area, thus minimizing the risk of traumatization of the patient.
 Background. Improving efficiency of endodontic treatment of teeth with apical resorption in the region of mandibular canal.
 Materials and methods. 56 patients aged between 18 and 45 years were examined. All patients had clinical signs of mandibular endodontic treatment failure with a dark radiolucent focus in the region of the apex, which bordered the mandibular canal. Radiological indicators and quality of obturation were assessed on the basis of CBCT, the presence of dentinal bridge was assessed visually using a dental microscope and an apical hermetic test. The results were evaluated after 4, 6, 12, and 24 months.
 Results. After 16 weeks of treatment, more than 70% of apical barrier formation occurred in groups 1 and 2, which allowed us to perform a quality permanent obturation without excessive risks of complications.
 Conclusion. The use of a dental microscope in conjunction with modern endodontic techniques in the treatment of teeth with apical resorption can significantly reduce the treatment time, thereby improving the quality of treatment of patients with this pathology.
