“…The statistical analysis of the areas of gutta percha inside the canal after retreatment, shows that Thermafil ® group has a minor number of residues in the apical third compared to the Warm Vertical compaction group and especially to the GuttaCore Pink ® group, although the difference is not statistically significant. This is also in accordance with the paper of 13,15) on the previous GuttaCore ® .…”

“…In addition, Endal et al 14) pointed out that GuttaCore ® can be removed in less time from root-end cavities than a root filling performed with a cold lateral condensation technique and Rödig et al 15) demonstrated that regaining a working length was significantly quicker with GuttaCore ® when compared with Thermafil ® and vertically-compacted gutta-percha.…”

The goal of non-surgical treatment is to obtain an access to the root canal system in order to remove the previous filling. We analized 45 human single-canal roots, mesial roots of mandibular molars and distal roots of maxillary molars without previous endodontic treatment, fractures, resorptive defects or open apices. We evaluated the time required to retreat root canals obturated by a new generation of GuttaCore, GuttaCore Pink ® , compared to Thermafil ® and Warm Vertically compacted gutta-percha, by using ProTaper ® Retreatment and ProTaper ® Universal. Moreover, a quantitative analysis of residual filling material in the canal after retreating and shaping was performed. The Kruskal-Wallis and Dunn's test were used to determine significant differences. Our data show that the GuttaCore Pink ® can be removed from the root canal system in a lower amount of time compared to the Thermafil ®. Concerning the amount of residual filling material, there are no significant differences between the three groups.

Background:Dental trauma is caused by fracture(s) in the vertical plane and the horizontal plane of roots. The objective of this study is to perform multiple diagnostic modalities for the diagnosis of horizontal root fracture(s) of the tooth.Methods:A total of 250 patients with dental complaints were subjected to intraoral radiography, multidetector helical computed tomography (MDHCT), and limited cone beam computed tomography (LCBCT). The suspected tooth was extracted, visually inspected, and subjected to microcomputed tomography (micro-CT). Images were observed in the lightbox, and a fracture was considered if it had been directly visualized as radiolucent line traversing tooth root. Wilcoxon test/Tukey post hoc test was performed at 99% of confidence level.Results:With respect to visual inspection, for LCBCT, intraoral radiography, MDHCT, and micro-CT, sensitivities were 0.988, 0.972, 0.967, and 0.979; accuracies were 0.956, 0.785, 0.905, and 0.888; false-positive values were 5, 21, 12, and 11; and false-negative values were 3, 24, 3, and 11, respectively. The area of the image visible at one time was in the order of treatment without radiography < intraoral radiography < MDHCT < micro-CT < LCBCT.Conclusion:The LCBCT had the highest sensitivity and accuracy for diagnosis of horizontal tooth root fracture(s).Level of Evidence:I.Trial Registry:researchregistry3647, dated December 31, 2016 (www.researchregistry.com).
