Effect of Glycolic Acid on the Bond Strength Longevity of Bioceramic and Resin Based Endodontic Sealers: An In Vitro Study
This study evaluated the effect of glycolic acid (GA) as a final irrigant on the long-term bond strength of AH Plus and Bio-C Sealer. Forty-eight single-rooted teeth were assigned to four groups (n = 12): ethylenediaminetetraacetic acid (EDTA) + AH Plus, glycolic acid + AH Plus, EDTA + Bio-C Sealer, and glycolic acid + Bio-C Sealer. The bond strength and failure pattern were evaluated immediately and after 6 months, while the interface adaptation and sealer penetrability were also assessed. Immediate bond strength did not differ between groups, but after 6 months AH Plus showed higher values than Bio-C Sealer. The failure pattern was similar among all groups at both evaluation time points. EDTA + AH Plus exhibited superior interface adaptation compared with EDTA + Bio-C Sealer, particularly in the cervical third. Sealer penetrability was comparable among groups. Glycolic acid produced similar outcomes to EDTA, and AH Plus maintained greater bond strength over time.
