The Effect of Ultrasonic Activation on Push-Out Bond Strengths of Two Calcium Silicate-Based Sealers to the Root Canal Wall

Research output: Contribution to journalArticlepeer-review

Abstract

The purpose of this study was to analyze the effects of ultrasonic activation on the bond strength of a calcium silicate-based sealer and a calcium silicate pozzolan-based sealer after a root canal procedure. 32 first premolar teeth extracted for orthodontic reasons were divided into four groups. Group 1 had a calcium silicate-based sealer, group 2 had a calcium silicate sealer with ultrasonic activation, group 3 had a calcium silicate pozzolan-based sealer, and group 4 had a calcium silicate pozzolan-based sealer with ultrasonic activation. An ultrasonic scaler and tip was used for the activation. The machine push-out bond strength of each group was measured to determine their connective strength. The stereomicroscope camera was used to determine the failure. Statistical Analysis: A one-way ANOVA test and post-hoc Tamhane test were used to statistically analyze the results (p = 0.05). There was a significant difference between calcium silicate-based sealer and calcium silicate pozzolan-based sealer (p = .015) and the common types failure was mixed failure (62.5%) The bond strength of calcium silicate pozzolan-based sealer was greater compared to calcium silicate-based sealer, and ultrasonic activation increased the bond strength of both types of sealers to the root canal wall.
