Abstract

Background. Vertical root fracture might occur during root canal preparation, obturation, post procedures or endodontic treatment. Methods. Fifty-four single-rooted human teeth were decoronated to obtain a standardized length. The root canals were enlarged up to #50 and obturated with gutta-percha and root canal sealer. Eighteen teeth were used as a control group, and vertical root fracture was induced in the remaining teeth. The samples were randomly divided into three groups, as follows: control group (without vertical root fracture), Super-Bond C&B group (fragments were attached with Super-Bond C&B), and self-adhesive dual-cured resin cement group (fragments were attached with self-adhesive dual-cured resin cement). Each specimen was subjected to a fracture resistance test, and data were statistically analyzed using chi-squared test, one-way ANOVA and post hoc Tukey tests (P=0.05). Results. The fracture resistance values of the control and Super-Bond C&B groups were higher than those of the self-adhesive dual-cured resin cement group (P<0.05). However, there were no significant differences between the control and Super-Bond C&B groups (P>0.05). Conclusion. Within the limitations of the present study, Super-Bond C&B was beneficial in obtaining higher fracture resistance in endodontically treated roots with vertical root fracture.

Summary

Introduction

Vertical root fracture (VRF) is one of the major reasons for extraction of endodontically treated teeth.[1]. Dual-cured resin cement,[5,6,8,9] polyethylene fiber,[6,9] glass fiber,[6,9] and Super-Bond C&B (Sun Medical Co, Ltd. Moriyama, Japan)[4,10] have been used to reattach the fragments. Japan)[4,10] have been used to reattach the fragments In most of these studies, dual-cured resin cement was used to attach the fragments as a main bonding material.[5,6,8,9] Super-Bond C&B, a trinbutylborane (TBB) initiated adhesive resin, is a selfcured adhesive resin cement based on methyl methacrylate. The aim of the present study was to evaluate the effect of Super-Bond C&B and self-adhesive dual-cured resin cement on the fracture resistance of roots with VRF. Vertical root fracture might occur during root canal preparation, obturation, post procedures or endodontic treatment
