Abstract
Objectives: To compare the push-out #bondstrength of root fillings made with either 2Seal or TotalFill BC sealer after the additional
instrumentation of oval canals with either the XP-endo Finisher (XP) or Self Adjusting File (SAF) systems.
Material and Methods: #Mandibularpremolars with single oval
canal were collected for the study. #Rootcanals were prepared with
Reciproc
R25 and were randomly divided into six groups (n=10), as follows: group
1, additional instrumentation with SAF and filling using 2Seal and
gutta-percha (GP); group 2, additional instrumentation with SAF and
filling using Total Fill BC and GP; group 3, additional instrumentation
with
XP and filling using 2Seal and gutta-percha; group 4, additional
instrumentation with XP and filling using Total Fill BC and GP; group 5,
#canalfilling with 2seal and GP without additional instrumentation; group 6,
canal filling with Total Fill BC and GP without additional
instrumentation.
Each sample was sectioned horizontally into 1 mm thick slices at each
thirds and push-out test was performed using universal testing machine.
Three-way ANOVA and Tukey’s post-hoc tests were performed to compare
groups.
