Abstract:
Aim: The aim of this study investigate bond strength with push-out test on post applied
teeth with three different self adhesive resin cement on obturated and unobturated root
canal and evaluated dentin tubule penetration with using confocal laser scanning
microscopy(CLSM) imaging technic and correlation between bond strenght and dentin
tubule penetreation of self adhesive resin cement. Material and Method: In this study 180
mandibular second premolar teeth roots were used. Fiber posts (Reforpost®) were applied
into the root canals with using three self adhesive resin cements (Maxcem Elite™,
RelyX™ U200, Panavia™ SA) with/without root canal filling(n = 15). Before insertion of
the post, sealer were labeled with fluorescein and the resin cement was labeled with
rhodamine B isothiocyanate. The roots were sectioned and each slice was analyzed using
confocal laser scanning microscopy. Bond strengths were measured using a micro push-out
test. Result: Push-out bond strenght value of obturated and unobturated group did not
showed significant difference. Bond strenght showed a statistically significant difference at
coronal part(p<0.005). The groups which has unobturated root canals exhibited statistically
different results at dentin tubule penetration depth for Panavia™ SA and RelyX™ U200
applications (p<0,001). Panavia™ SA exhibited greater dentin tubular penetration
percentage(p=0,003). Conclusion: Panavia™ SA and RelyX™ U200 cement the better
bond strength and better dentine tubule penetration values than Maxcem Elite™ cement.
