ROLE OF QUALITATIVE ENDODONTIA IN THE SCHEME OF INTERDISCIPLINARY TREATMENT OF MAXILLARY ODONTOGENIC SINUSITIS

Abstract

In the treatment of odontogenic maxillary sinusitis, the removal of causative teeth is actively used, although the tooth removal indications are not always clearly defined. Modern endodontic approaches and technologies, in most cases, help preserve the tooth in the oral cavity with the elimination of the chronic infection focus, thus restoring the integrity of the maxillary sinus.
 Background. Improve the effectiveness in the treatment of odontogenic maxillary sinusitis while preserving the causative teeth.
 Materials and methods. The study involved 50 patients aged 18 to 45 years. All patients had clinical signs of maxillary odontogenic sinusitis and signs of failed endodontic treatment of teeth with a dark, radiolucent focus in the apex region. Radiological parameters and quality of obturation was assessed using CBCT; the presence of symptoms of inflammation was assessed clinically during examination. The results were evaluated after 6, 12 and 24 months. The treatment effectiveness and the quality of obturation was assessed in accordance with the directives of the European Society of Endodontology.
 Results. High-quality endodontic treatment resolved clinical signs of odontogenic sinusitis in all patients, restored the bone tissue of the alveolar process and restored the mucous membrane of the maxillary sinus after 12 months in 96% of cases. In 2 cases, additional microsinusotomy was required.
 Conclusion. Improving the quality of endodontics in the first treatment or retreatment of the upper jaw teeth can significantly reduce the number of dental extractions in odontogenic maxillary sinusitis
