Abstract

The purpose of this study was to evaluate produced voids in the root canal system following obturation with dentin adhesive materials. Forty-two single rooted human maxillary premolars were used. The crowns were removed and the root lengths were standardized to 12mm. Twenty-one teeth were instrumented to ISO size #40 and the remaining 21 to ISO size #80 by the standardized method. Each group was randomly divided into three groups of 7 teeth each as follows: Group A: gutta-percha+RoekoSeal Automix® using vertical condensation method Group B: gutta-percha+MetaSEAL™ using single-cone technique Group C: Resilon™+Epiphany® SE™ using vertical condensation method After the canal sealers had set, the roots were imaged using cone-beam computed tomography. The images were evaluated for the number and location of the voids by three dentists. Obtained data were statistically analyzed using 2-way ANOVA and the Tukey-Kramer test at the 5% significance level. Statistical analysis revealed that the number of voids and the projected area of voids in Group B were significantly larger than those in Group A (p<0.05; 2-way ANOVA). Root canal obturation with gutta-percha and MetaSEAL™ using the single-cone technique produced a significantly larger number of voids and larger projected area of voids compared to Group A.
