using ultrasonic devices in endodontics can enhance the antibacterial and tissue dissolving ability of different root canal irrigants such as sodium hypochlorite (naocl) which is the most common irrigant with excellent antibacterial and tissue dissolving abilities. however, due to its high surface tension, its penetration into the irregularities of the root canal system is a challenge. the purp...

Introduction: The main goal of the successful endodontics is the complete sterilization of the root canal space. During preparation, irrigants and debris such as bacteria, dentin fillings and necrotic debris may be extruded into the periradicular region leading to periapical inflammation and postoperative flare-ups. Several instrument designs and irrigation techniques have been developed to pre...

Background: Due to the anatomical complexity of root canal system, irrigation plays an essential role in endodontics. This vitro study was sought compare removal smear layer (RSL) promoted by conventional (CI), passive ultrasonic (PUI) and continuous (CUI) with 17% EDTA, using scanning electron microscopy (SEM). Material Methods: Forty single-rooted human mandibular canines were instrumented ra...

Objective To evaluate the degree of postoperative pain in patients with necrotic teeth symptomatic apical periodontitis after applying ultrasonic irrigation or manual dynamic agitation.
 Methods Seventy-eight diagnosed mandibular first molar were randomly allocated into 1 3 separate groups (n=26); Manual Dynamic Agitation group, Ultra X NaviTip group (control). After a single-visit root ca...

Objective This study compared the effectiveness of Er:YAG laser-activated irrigation (PIPS), passive ultrasonic irrigation (PUI) with EndoUltra and standard needle irrigation (SNI) in the removal of calcium hydroxide [Ca(OH)2] from the mesial roots of Weine Type II mandibular molars. Material and Methods Thirty mandibular molars were screened by µCT for the presence of mesial roots with compl...

INTRODUCTION Infecting microorganisms of the root canals are difficult to eliminate during endodontic treatment. In this study the effect of root canal disinfection with photodynamic therapy (PDT) at different time intervals in comparison to 2.5% sodium hypochlorite (NaOCl) irrigation and passive ultrasonic irrigation (PUI) in extracted teeth colonized with Enterococcus faecalis and Candida alb...
