Abstract
ABSTRACT Objective To evaluate the plant‐derived compound lignin (LIG) as a pretreatment of intraradicular dentin in combination with EDTA on push‐out bond strength (PBS) and nanoleakage of the glass fiber posts (GFPs) cemented using adhesive resin cement. Material and Methods Twenty‐eight human incisor roots were prepared for GFP cementation and divided based on dentin pretreatment: (1) CONTROL: no pretreatment, (2) EDTA: 17% EDTA for 3 min, (3) EDTA‐LIG: 17% EDTA and 2% lignin for 3 min, (4) EDTA‐PAC: 17% EDTA and 2% lignin for 3 min. The GFPs were cemented using the self‐adhesive resin cement Multilink Speed. The roots ( n = 7) were sectioned into 1 mm‐thick discs and subjected to PBS testing after 1 week or 6 months. Nanoleakage was analyzed by SEM. Statistical analysis was performed using two‐factor ANOVA and Tukey's test ( p < 0.05). Results Higher PBS was identified for the CONTROL group ( p < 0.001). After 6 months, the EDTA‐LIG maintained the bond strength with a predominance of mixed failures, while the EDTA‐PAC, EDTA, and CONTROL groups showed reduction of bond strength, with a predominance of adhesive failures along with severe silver infiltration in the interface. Conclusion LIG associated with EDTA as a pretreatment for intraradicular dentin shows significant potential for attaining stable bond strength and interfacial integrity of self‐adhesive resin cement to intraradicular dentin.
