EXTRACTION OF FIBER POST DURING REPEATED ENDODONTIC TREATMENT OF TEETH WITH CHRONIC PERIODONTITIS

Abstract

Objective. To improve the method of safe removal of the fiber post during endodontic dental retreatment using a mediumpowered ultrasonic unit with minimization of the risk of damage to tooth tissue and alveolar tissue.

Material and methods. The clinical study involved 40 patients with chronic periodontitis (K04.5, K04.6, K04.7) which required endodontic treatment. In all patients, the tooth of concern had previously been restored with a fiber post, which had to be removed for access to the root canals and further unsealing. Efficacy was evaluated clinically (absence of periodontal symptoms) and radiologically (RVG and CBCT scans before treatment, immediately after treatment, and 3-6 months later). The main methods included collection of complaints, medical history, examination, probing, percussion and palpation. Radiological examination was performed using Dental X-ray unit (Rextar LCD) and Planmeca tomograph with Planmeca Romexis Viewer. Fiber posts were removed using a medium-power ultrasonic unit with StartX 3 nozzle (Dentsply Sirona) and interrupted water cooling. The procedure time was 30-60 seconds.

Results. The study showed a positive trend in treatment: the disappearance of clinical symptoms and a decrease in foci of bone destruction on radiographs and CT scans 3-6 months after the removal of the fiber posts.

Conclusion. The ultrasound method of removing fiberglass posts during repeated endodontic treatment is safe and clinically effective. The advantage of the technique is the absence of complications typical of alternative methods.
