Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential replacement of sodium hypochloride. This article reviews the potential irrigants with their advantages and limitations with their future in endodont...

AIM To analyze the influence of the needle type, insertion depth, and irrigant flow rate on irrigant flow pattern, flow velocity, and apical pressure by ex-vivo based endodontic irrigation computational fluid dynamics (CFD) analysis. METHODS Human upper canine root canal was prepared using rotary files. Contrast fluid was introduced in the root canal and scanned by computed tomography (CT) pr...

INTRODUCTION The aim of this study was to evaluate the effect of needle tip design on the irrigant flow inside a prepared root canal during final irrigation with a syringe using a validated Computational Fluid Dynamics (CFD) model. METHODS A CFD model was created to simulate the irrigant flow inside a prepared root canal. Six different types of 30-G needles, three open-ended needles and three...

In dentistry, root canal therapy is the internal cleaning of a complex channel network contained within the tooth. The aim is to disinfect the canal and remove any remaining bacteria to prevent further infection prior to root filling. Irrigant solutions play an important role in this procedure as they allow canal debridement. Sodium hypochlorite (NaOCL) is an irrigant that is clinically recomme...

Root canal irrigants play a significant role in the elimination of microorganisms, tissue dissolution, and the removal of debris and smear layer. Sodium hypochloride is the most commonly used endodontic irrigant, despite limitations. None of the presently available root canal irrigants satisfy the requirements of ideal root canal irrigant. Newer root canal irrigants are studied for potential re...

INTRODUCTION The aims of this study were to evaluate dentin debris removal from the root canal during ultrasonic activation of sodium hypochlorite (2% and 10%), carbonated water, and distilled water and to determine the influence of 3 ultrasonic refreshment/activation cycles of the irrigant by using the intermittent flush technique. METHODS Root canals with a standardized groove in 1 canal wa...

statement of problem: bacterial agents are the primary cause of pulpoperiapical diseases. therefore, an irrigating solution with proper antibacterial ability should be used to eliminate the bacterial agents during canal instrumentation. purpose: the aim of present study was to compare the antibacterial effect of 0.2% chlorhexidine to 0.5% sodium hypochlorite as canal irrigating solutions. mater...

INTRODUCTION The aim of this study was to evaluate the effect of needle-insertion depth on the irrigant flow inside a prepared root canal during final irrigation with a syringe and two different needle types using a Computational Fluid Dynamics (CFD) model. METHODS A validated CFD model was used to simulate irrigant flow from either a side-vented or an open-ended flat 30-G needle positioned i...

The objective of this project was to evaluate the safety of various intracanal irrigation systems by measuring the apical extrusion of irrigant. Twenty-two single canal, extracted mature teeth were instrumented and secured through the lid of a scintillation vial to collect apically extruded irrigant. A precision syringe pump delivered controlled amounts of irrigant at a constant flow. The irrig...

3. Tasdemir T, et al. (2008). Effect of Passive Ultrasonic Irrigation on Apical Extrusion of Irrigating Solution. Eur J Dent. Methods: Measured amount of NaOCl through the apical foramen when NaOCl was left in the canal versus passive ultrasonic activation of the irrigant conclusions: PUI extruded significantly less irrigant than the control group (2.15 ± 2.73 versus 14 ± 13.03 uL, respectively...
