Root canal obturation with thermoplastic gutta - percha using „System B"

Abstract

Introduction: The treatment of apical periodontitis is an actual problem of modern therapeutic dentistry. Sometimes contradictory, multiple methods of treatment cause difficulties in choosing the curative remedy and canal obturation technique. In case of inadequate treatment, or bad quality filling of the canals, there can appear various complications as odontogenic inflammation followed by consumption. Latest studies have shown that 60% of the failure in endodontic therapy is because of incomplete fillings of canal space. Endodontic treatment that consists of sealing hermetically the root canal, over its whole length and width, will be completed by three-dimensional filling. A precise, hermetic and durable fill puts the canal system out of the circuit and isolates it from periapex. In such a way the periapex will remain well isolated from endodontic space, thus preventing possible complications. The goal of the current research is to study the thermomechanical gutta-percha condensation technique for root canal filling. The aims: 1. To study the advantages of the thermomechanical gutta-percha condensation technique; 2. To implement the nominated approach in performing this study of root canal filling in cases of periodontitis. Methods and materials: The analysis of bibliographic data and root canal filling methods pointed out the idea of studying the heated lamination technique, System B. According to the world-class endodontic specialists, the root canal filling by using the vertical condensation method with thermoplastic guttapercha, is nowadays the safest method to seal the endodontic canal system. The specialists from US have the same opinion- as it is a well-known center of modern endodontia. The method has been studied at „Fală Dental’clinic. We assisted 11 patients with chronic periodontitis. Also we put into practice the method itself twice by obturating two cases of periodontitis of root canal. The results: Analyzing 11 cases that we have been monitoring and two cases that we have put into practice, we observed that there were no complications arising after root canal filling with plastified gutta percha using System B. Conclusions: 1. According to the bibliographic data, the usage of gutta percha for different canal filling techniques, is very popular among all the dentists in the world. 2. The System B of filling the root canal with thermoplastic gutta percha shows no difficulties in implementation. 3. The technique of root canal filling using System B does not require significant time.
