Assessment of the quality of root canal obturation of teeth with destructive forms of periodontitis using Silpex (SEM studies)

Abstract

AIM. To evaluate the effectiveness of using the material Sealpex with gutta-percha pins using the lateral condensation method for permanent obturation of the root canals of teeth with periapical pathology and pathologically destroyed apical constriction.MATERIAL AND METHODS. The root canals of 94 teeth with destructive forms of periodontitis were filled with Sealpex. Depending on the degree of apical constriction, patients were divided into three groups. Follow-up of patients was carried out for 4 years.RESULTS. Using SEM, in 80% of cases, single micro cracks were detected between the dentin of the root canal wall and the sealer. In the area of wide apical openings, the fit of the material is loose, and it is removed beyond the root apex. The material diffuses into the root dentin. Statistical studies have shown a high percentage of successful treatment of destructive forms of periodontitis with the use of Sealpex.CONCLUSIONS. Endo-sealant extended beyond the apex of the root canal does not mean dense obturation of the apical foramen. The presence of micropores and microcracks in the endosealant can be regarded as evidence of poor sealing of the channel. The use of Sealpex is especially effective when filling teeth of groups, I and II with destructive forms of periodontitis
