Abstract
ABSTRACT
This study aimed to evaluate the effect of sodium hypochlorite (NaOCl) and ethylene diamine tetra-acetic acid (EDTA) on the bonding and sealing ability of different root repair materials.
Methodology: for the push-out bond strength test, ninety dentine discs with 2 mm thickness and a central opening of 1.5 mm were used. The discs were randomly distributed into 3 groups (n=30) based on the repair material used (white MTA Angelus, Biodentine, and Well-Root putty). The materials were condensed inside each disc and allowed to be initially set for 10 minutes. Then each group was further subdivided into 3 subgroups (n=10) based on the irrigant used (NaOCl, EDTA, and no irrigation was used in the 3rd control group) and immersed into the corresponding irrigant for 30 minutes. After complete setting for 72 hours, the bond strength was evaluated with a universal testing machine. For the sealing ability, the same methodology was followed but instead of using dentine discs, we used human-extracted lower molar teeth (n=72) with a standard furcation perforation. After 72 hours, the specimens were subjected to the dye penetration test to assess the sealing ability.
Results: Well-Root putty showed the highest bond strength and Biodentine showed the highest sealing ability.
Conclusion: NaOCl had a positive effect on the bond strength and sealing ability of both Biodentine and Well-Root putty while the EDTA had a negative effect on the properties of the three tested repair materials.
