Abstract
Purpose: To investigate the effect of 10% Proanthocyanidin (PA) rich grape seed
extract (GSE) and cardanol oil applied for 60s on immediate and long-term shear
bond strength (SBS) of etch and rinse to dentin. Materials and methods: The occlusal
surfaces of forty two samples were ground to expose flat superficial dentin surfaces.
The samples were divided into 3 groups; Group A1 (control group) without any pretreatment,
Group A2 (10 % GSE), Group A3 (cardanol). Pre-treatments were applied
for 60s and then washed away for 30s. Each group was further randomly subdivided
into two groups (n=7) according to the storage time (immediate 24 hours) and (longterm
six months period). Shear bond strength (SBS) was tested using a universal testing
machine at a cross head speed of 0.5mm/min. Data was tabulated and presented as
mean and standard deviation, one-way ANOVA, post hoc Tukey’s test for pairwise and
Paired student t-test was performed between paired groups. Results: All pre-treatment
groups showed statistically no significant SBS values after 24 hours of storage. While
at 6 months storage, group A3 showed the highest SBS mean value followed by
group A2 while Control Group recorded the lowest shear bond strength mean value.
Conclusion: Natural dentin Bio-modifiers are considered effective in improving the
shear bond strength of the bonded interface and the Bond strength of dentin is affected
by the storage time.
