Abstract
ABSTRACT
Aim: To evaluate the efficacy of chitosan as a post- space irrigant on bond strength of glass
fiber posts luted with self-adhesive resin cements.
Methodology: thirty single rooted human mandibular premolars with similar dimensions
were decoronated to a standard root length of 15mm, endodontically treated and subjected to post
preparation to a 10mm length. Specimens were randomly divided in to 3 groups according to the
post space irrigant (PSI) to be used in to group (Saline, EDTA, Chitosan) n=10 each. Following
irrigation procedure glass fiber posts (GFP) (Glassix radiopaque, H Nordin, Chailly/Montyreux,
Switzerlandand) were cemented using self-adhesive resin cement (RelyX U100). Specimens were
sectioned perpendicular to the long axis into 1mm thick slices. Three slices (one representative of
each root third) from each specimen were subjected to push- out test and bond strength in MPa was
statistically analyzed.
Results: the bond strength was significantly higher in both EDTA and Chitosan groups than
saline group P < 0.001. Bond strength was significantly affected by the region of the root canal
P< 0.001.
Conclusion: PSI affects the bond strength of GFP luted with self-adhesive resin cements.
Chitosan can serve as a safer alternative for EDTA as a chelating agent. Chitosan as a PSI has a
positive influence on the bond strength of GFP luted with self-adhesive resin cements.
