Objectives:The
aim of this study is to compare the effects of intracanal treatments with
calcium hydroxide (CH) or triple antibiotic paste (TAP) on bond strength of a
calcium silicate-based sealer (MTA Fillapex) and an epoxy resin- based sealer
(MM Seal).
Materials and Methods: Sixty extracted maxillary central incisors were prepared
with a rotary system to size 40. The specimens were randomly divided into two
groups, which received either intracanal CH or TAP. After rinsing, the teeth in
each group were further divided into two additional groups, which were
obturated with gutta percha and either the MTA Fillapex or MM Seal root canal
sealer. Then, slices were obtained from three sections of the canal (coronal,
middle, and apical). A push-out test was performed to measure the bond strength
between the root canal dentin and the sealer.
Results: The
push-out bond strengths of the root canal sealers were significantly affected
by the type of intracanal medicament. Both the sealers showed bond strengths
that were nearly two-fold higher after TAP application than after CH
application, and these results were independent of the position along the
canal.
Conclusions: The
use of TAP rather than CH improves the bond strength of calcium silicate- and
epoxy resin-based sealers throughout the root canal.
