Background:
The bond strength of the root canal sealers to dentin
is very important property for maintaining the integrity and the
seal of root canal filling.
Aim:
The aim of this study is to evaluate and compare the push-
out bond strength of root filled with total fill bioceramic (BC), AH
Plus and Gutta-flow®2 sealers using GuttaFusion® obturation
system versus single cone obturation technique.
Materials & Methods:
Sixty of mandibular premolars teeth
with straight roots were used in this study, these roots were
instrumented using RECIPROC® system, instrumentation were
done with copious irrigation of 3 mL 5.25% sodium hypochlorite
solution (NaOCl) during all the steps of preparation, and smear
layer will be removed with 1ml of 17% EDTA kept in the canal for 1
min, roots were randomly divided into two groups according to the
obturation technique (thirty teeth for each group): Group I: Single
RECIPROC® Gutta percha cone obturation technique, Group II:
Gutta fusion obturation technique, then each group divided into
three subgroup according to the type of sealer, AH subgroup: AH
Plus sealer, BC subgroup: bioceramic sealer and GF subgroup:
Gutta flow 2 sealer. The roots then stored in moist environment
at 37°C for one week, the roots were embedded in clear acrylic
resin and each root sectioned into three levels apical, middle and
cervical. The bond strength was measured using computerized
universal testing machine each section fixed in the machine so
that the load applied from apical to cervical direction at 0.5mm/
min. speed and the computer show the higher bond force before
dislodgment of the filling material. These forces were divided by
the surface area to obtain the bond strength in MPa.
Results:
Statistical analysis was performed and the result
showed a highly significant differences between the three types
of sealers when the same obturation technique were used, also
there is highly significant differences between two groups with
two different obturation technique.
Conclusions:
This study showed that the push out bond strength
ofAHplussealerwashigherthanbioceramicsealerandGuttaflow
2 sealer respectively when the same obturation technique was
used. The push out bond strength was affected by the obturation
technique and Gutta fusion obturation technique showed higher
bond strength than single cone obturation technique when the
same type of sealer was used.
