The Influence of Different Obturation Technique on the Density of Root Canal Filling

TLDR: This study in vitro was to study the influence of different obturation techniques on the density of root canal filling and suggest the best technique for obturate the root canal in three dimensions and better apical control.

Abstract: Background: One of the prerequisites for successful of endodontic therapy is the complete filling of the root canal system and the important thing to achieve this goal is the good placement of filling material to the canal wall. The techniques of the obturation were developed widely for achieving this object and many studies were done, but most of then were done on transparent acrylic blocks not on the human teeth. Objective: The purpose of this study in vitro was to study the influence of different obturation techniques on the density of root canal filling and suggest the best technique for obturate the root canal in three dimensions and better apical control. Materials and Methods: 60 first upper teeth were instrumented using K3 technique, the teeth were weighed and assigned to two distributed groups. Group A was obturated with the lateral condensation technique. Group B was obturated with the continuous wave of condensation technique. The teeth weighed again after obturation . Results: results were analyzed using t test. The results were that the continuous wave gives greater density (0.080g) than the cold lateral technique (0.043g) So the system B gives greater gutta percha than lateral condensation. Discussion: All the teeth were prepared to the same size and obturated with the same master apical point of Gutta Percha and we didn't use any sealers so, the increase in weight is dun to the increase in Gutta-Percha itself and
