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...

introduction: the aim of the present in vitro study was to evaluate the disinfection ability of 980-nm diode laser in comparison with sodium hypochlorite (naocl) as a common root canal irrigant in canals infected with enterococcus faecalis ( e. faecalis ). methods and materials: the root canals of 18 extracted single-rooted premolars were prepared by rotary system. after decoronation, the roots...

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...

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...

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...

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...

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...

INTRODUCTION The root canal anatomy of the teeth is very complex. Complete debridement of the root canals is a challenge and is very important for the success of the root canal treatment. Hence, this study was done to find an effective irrigant which can be used during root canal treatment. OBJECTIVE The bactericidal effect of a potential root canal irrigant was compared with two commonly use...

AIM To assess radiographically irrigant penetration in the root canal system of curved roots during root canal shaping procedures ex vivo. METHODOLOGY Thirty extracted mandibular molar teeth with moderate to severe curvature were used. A special aiming device was used to guarantee that each successive radiograph was taken with the same positioning. The mesiolingual canal of each tooth was ins...
