Abstract

Introduction: The objective of this study was to evaluate the effect of SmearOFF, 7% maleic acid (MA) and 17% ethylenediaminetetraacetic acid (EDTA), on the surface microhardness of Biodentine (BD). Materials and Methods: Forty BD cylindrical‑shaped specimens were prepared using a split mold and were divided randomly into four groups (n = 10) based on the type of irrigant used for 1 min. In Group I, the specimens were treated with 17% EDTA, in Group II with 7% MA, in Group III with SmearOFF solution, and in Group IV with 5 mL distilled water. In all these groups, the irrigants were taken in a beaker and the samples were immersed with a magnetic stirrer placed to ensure complete wetting of the specimens. All the samples were then washed with distilled water and air‑dried. The surface microhardness of the specimens was measured using Knoop hardness tester. Data were analyzed statistically using Kruskal–Wallis and Mann–Whitney U‑test. The significant level was preset to P = 0.05. Results: MA significantly compromised the microhardness of BD followed by EDTA, SmearOFF, and distilled water which was statistically significant (P < 0.001). On comparison between 17% EDTA and SmearOFF, 17% EDTA reduced microhardness to maximum (P < 0.05). Conclusion: In conclusion, the present study demonstrated that microhardness of BD cement was generally affected by chelating agents.
