Aim: This study was aimed to determine the use of calcium hydroxide (Ca(OH)2) intracanal medicament effect on the push-out bond strength of RelyX Unicem self-adhesive cement onto the root canal wall.
Materials and Methods: A total of 50 extracted human maxillary permanent incisor teeth were randomly divided into control and experimental groups (n = 25 for each group). The control group was prepared for routine root canal treatment followed by post space preparation. RelyX Unicem self-adhesive cement is used for the cementation of fiber post in the root canal, as in experimental group, Ca(OH)2intracanal dressing was placed into the root canal for a week, followed by root canal filling, post space preparation, and cementation of fiber post using RelyX Unicem cementation. Each sample was divided into coronal, middle, and apical root sites. They were horizontally sliced and examined using scanning electron microscope (SEM). Three slices from each of the three sites were subjected to push-out test for bond strength measurement. Independent t-test was used to compare the push-out bond strength of RelyX Unicem on the root canal wall. One-way analysis of variance and pairwise comparison test were used for the statistical analysis. The significant level was set as P < 0.05.
Results: The significant differences in bond strength were demonstrated between the different sites of the root, where the coronal and apical with the P value 0.031 and 0.020, respectively. However, the middle third of the root showed no statistically significant difference, where P = 0.072.
Conclusions: Intermediate Ca(OH)2dressing has an effect on the bond strength of RelyX Unicem self-adhesive resin cementation on the root canal wall.
