Context:
The long-term retention of fiber posts in endodontically treated teeth is fundamentally dictated by the integrity of the adhesive bond between resin cement and the dentin hybrid layer, as any compromise in quality jeopardizes the post-cement-dentin interface. This study evaluates the bonding efficacy of total-etch, self-etch, and self-adhesive systems to root dentin for fiber post cementation. The findings provide evidence-based guidance for selecting an optimal adhesive strategy in clinical practice.
Objective:
This study compared the bonding potential of total-etch (TE), self-etch (SE), and self-adhesive systems for glass fiber post-to-root dentin.
Materials And Methods:
Sixty mandibular premolars with a single root extracted freshly were standardized to a root measuring 15 mm in length after decoronation. Root canal treatment was performed, with sodium hypochlorite and ethylenediaminetetraacetic acid as irrigating solutions. The canal was obturated with gutta-percha and sealer using the sectional obturation technique. Post space was prepared with fiber post drills. The samples were distributed into three groups (n = 20) based on the adhesive system applied to lute the glass fiber post: • Group A: TE adhesive system, • Group B: SE adhesive system, • Group C: Self-adhesive system. Middle portion of sample was used to evaluate bond strength under a universal testing machine.
Results:
The Statistical analysis was conducted using Stata Statistical Software, Version 18 (StataCorp, 2023; College Station, TX: StataCorp LLC). A one-way analysis of variance (ANOVA) was performed to compare the means among groups, with statistical significance set at P < 0.05. Post hoc comparisons were carried out using Tukey's honest significant difference test to determine significant differences between the groups. Therefore, found that group B (SE adhesive) exhibited the highest mean bond strength at 131.03 N, which was statistically highly significant (P = 0.001) compared to the other groups. Group A (TE adhesive) demonstrated a bond strength of 115.25 N, while Group C (self-adhesive) showed the lowest bond strength at 75.04 N.
Conclusion:
The SE adhesive system demonstrated superior bond strength compared to TE and Self-Adhesive systems, making it the best choice for fiber post luting.
