Abstract

The objective of the study was to three dimensionally compare the density and homogeneity of “GuttaFlow®” using backfilling technique with conventional lateral compaction technique using spiral computed tomography. 30 human extracted maxillary central incisors were used for this study. Following access cavity preparation, working length was determined and root canal preparation was carried out using standard step-back technique. Root canal irrigation was performed using 2.5% NaOCl ,saline and final flushing with 17%EDTA and normal saline. After root canal preparation, the specimens were randomly divided into 3 groups with 10 teeth in each group. Specimens in Group-I were obturated with GuttaFlow® using backfilling technique, Group-II were obturated by lateral compaction technique using GuttaFlow® as the sealer and Group-III were obturated by lateral compaction technique using zinc-oxide and eugenol as the sealer. The specimens were then analyzed in both horizontal and vertical sections from the apex to the cemento-enamel junction of each specimen with section thickness of 1mm each using Spiral Computed Tomography. The data obtained was statistically analyzed using one way ANOVA test followed by FISHER’S test and TUKEYS HSD test. Results showed that specimens of Group -I was denser, more homogenous compared to other groups and was statistically significant. In the evaluation of obturation in the apical, middle and coronal third individually, Group -I showed better results than other groups in apical and middle third which was statistically significant, but showed inferior results in the coronal third though it was not statistically significant. And Group-II and Group-III showed inferior results in the middle third when compared with Group-I and was statistically significant. From the results of the study it can be concluded that, Obturation done using GuttaFlow® with backfilling technique is superior in the apical and middle third but is inferior in the coronal third of the root canal system when compared to lateral compaction technique. Spiral computed tomography is a very useful tool fo checking the density of obturation in endodontics.
