Abstract

ABSTRACTObjective The aim of this study was to investigate the effectiveness of conventional syringe irrigations, passive ultrasonic irrigation (PUI), Vibringe, CanalBrush, XP-endo Finisher, and laser-activated irrigation (LAI) systems in removing double antibiotic paste (DAP) from root canals.Material and Methods One hundred five extracted single-rooted teeth were instrumented. The roots were split longitudinally. Three standard grooves were created and covered with DAP. The roots were distributed into seven groups: Group 1, beveled needle irrigation; Group 2, double side-vented needle irrigation; Group 3, CanalBrush; Group 4, XP-endo Finisher; Group 5, Vibringe; Group 6, PUI; Group 7, LAI. The amount of remaining DAP was scored under a stereomicroscope.Results Group 4, Group 6, and Group 7 removed significantly more DAP than the other protocols in the coronal region. Group 7 was more efficient in the middle region; however, no significant difference was found between Group 7 and Group 6. No differences were found between groups in the apical region either, except for the comparisons between groups 7 and 2, and groups 2 and 3.Conclusions None of the investigated protocols were able to completely remove the DAP from the grooves. The Vibringe and XP-endo Finisher systems showed results similar to those of conventional needle irrigation.

Summary

Introduction

The main goal of root canal treatment is to enlarge the root canal system and to eliminate and discharge bacteria from it. For this purpose, numerous instruments, irrigation solutions, and medicaments have been used.

Chemomechanical preparation reduces the bacteria population, none of the contemporary techniques can completely clean the root canal system. Intracanal medicaments are used to eliminate and/or reduce the number of bacteria from the canal. Calcium hydroxide (CH) is widely used as an intracanal medicament between appointments to enhance the incidence of bacteria free canals.
