Effect of Calcium Hydroxide, 3-Mixtatin and Silver Diamine Fluoride as Intracanal Medicaments on Push out Bond Strength of AH Plus Sealer: An in-Vitro Study

Abstract Purpose: To determine the effect of intracanal medicaments on push out bond strength of AH plus sealer. Materials: Eighty extracted human permanent single-rooted teeth with fully formed apices were selected, access opening and biomechanical preparation was done, specimens were divided into four groups based on the type of intracanal medicament placed. Group I control with no intracanal medicament, Group II RC cal was placed as intracanal medicament, Group III 3-Mixtatin placed as intracanal medicament, In Group IV Silver diamine fluoride was placed as intracanal medicament, After one week of incubation at 37oC, the intracanal medicament was removed and obturated with AH plus sealer using single cone obturation technique and the specimens were subjected to universal testing machine. Results: The highest bond strength was shown by 3-Mixtatin group followed by Silver diamine fluoride, RC Cal and control groups. Among all the groups, the bond strength was higher in apical1/3rd, followed by middle1/3rd and least at coronal1/3rd. Conclusion: 3-Mixtatin and SDF can be efficiently used as intracanal medicaments as an alternative to conventional medicaments because of improvement in the push out bond strength values of AH plus sealer.
