Finger spreaders insignificantly affect packing the gutta-percha cones. This survey aimed to compare the compaction index of root canal obturation obtained with Stainless Steel (SS) and Nickel-Titanium (Ni-Ti) spreaders and different gutta-percha tapers. Materials and Methods: Forty extracted maxillary central incisors were randomly divided into 4 groups of 10 teeth. In group 1, the canals were filled with 0.02 tapered gutta-percha and SS spreader; group 2 with 0.02 tapered gutta-percha and Ni-Ti spreader; group 3, with 0.04 tapered gutta-percha and SS spreader, and group 4 with 0.04 tapered gutta-percha and Ni-Ti spreader. The compaction index was compared among the different groups using the Independent Samples t-test. Results: The mean compaction index for the groups that were filled with 0.02 tapered gutta-percha cones was 1.44 with the use of SS spreaders and 1.18 with the use of Ni-Ti spreader; however, the difference was not statistically significant. Furthermore, the mean compaction index for the groups that were obturated with 0.04 tapered gutta-percha cones was 1.561 with the use of SS spreaders and 1.269 with the use of Ni-Ti spreaders. Similarly, this difference was not statistically significant. Conclusion: The obturation compaction index was higher when using SS spreaders and 0.04 tapered gutta-percha cones; however, the differences were not statistically significant. %> http://3dj.gums.ac.ir/article-1-327-en.pdf %P 163-166 %& 163 %! %9 Original article %L A-10-328-5 %+ Dentistry Student, Student Research Committee, School of Dentistry, Guilan University of Medical Sciences, Rasht, Iran. %G eng %@ %[ 2018
