Abstract

Objective: This study aimed to assess the effect of the cold and warm obturation techniques on the amount of apically extruded debris (AED) and time needed for the removal of filling material during endodontic retreatment using the XP endo retreatment files.

Methods: Sixty single-rooted lower premolars with round-shaped canals were selected for the study. The canals were prepared and obturated with one of four obturation techniques (N=15): cold lateral compaction (CLC), single-cone (SC), thermoplasticized gutta percha injection (TGP), and gutta core (GC) obturation techniques. All the root canal fillings were removed using XP endodontic retreatment files. The mean weight of the AED was estimated with an analytical balance to an accuracy of 10-4 g. AED data were subjected to Kruskal-Wallis and a one-way ANOVA, post hoc Tukey's test for the time factor, with a significance level ≤ 0.05.

Results: AED data revealed significant differences among groups (p=0.039). The CLC technique was significant compared to TGP, with a significance level of p=0.018, and significant compared to the SC technique, with a significance level of p=0.034. Also, there were highly significant differences between groups regarding the time needed for retreatment (p=0.000).

Conclusions: The obturation technique influences AED, and time for root canal retreatment. CLC resulted in less debris extrusion, while SC resulted in higher debris extrusion and TGP required the least time for root canal retreatment.
