Abstract

ABSTRACT
Introduction: The purpose of the research was to assess the impact of the final irrigant activation of ER: YAG laser with PIPS technique and ultrasonic irrigant activation by Ultra-X endoactivator (Changzhou Sifary Medical Technology, China) on the penetration depth of the bio-ceramic sealer (Meta Biomed Ceraseal, Korea).
Methods: 60 human mandibular premolars were utilized in the investigation. The access cavities were made. To achieve a size #40 apical preparation, all teeth were instrumented using a crown-down technique, using a set of ProTaper Next rotary instruments. Following biomechanical preparation, teeth were divided equally into 4 groups (n=15) G1 (Manual dynamic agitation), G2 (Passive ultrasonic instrumentation), G3 (PIPS technique), and G4 (No activation). The sealer was combined with the Rhodamine B dye to analyze the penetration of the sealer through the CLSM. Obturation was performed out in a single cone approach. Three slices (2 mm) were cut off from each root to symbolize the coronal, middle and apical thirds. The finding was tabulated and subjected to statistical analysis.
Results: There was substantial variation among different groups. The PIPS group had the greatest value, followed by PUI, then MDA, while the lowest value was found in No activation group.
Conclusion: The final irrigant activation strategy had a considerable impact on sealer penetration into the dentinal tubule. Use of PIPS tip or PUI seems advantageous in dentinal tubule penetration of a calcium silicate bioceramic sealer
