“…There was considerable heterogeneity (I 2 = 93%) when data from six studies[202223242526] were pooled; therefore, a random effects model of analysis was used. This meta-analysis revealed greater apical extrusion of debris in the Rotary ProTaper group compared to Wave One group; however, the difference was not statistically significant ( P = 0.24) that is P > 0.01.…”

“…[232426] The reason for this may be attributed to the fact that, in a Wave One instrument, reciprocation tries to mimic the balanced force technique kinematics, which is well known as being a pressure less movement pushing less material periapically. [2] The interplay among several factors such as instrument design, improved alloy, fewer instruments, high cutting ability, and reciprocation kinematics of Wave One system can be used to support their improved control of apically extruded debris[16] found in the present study.…”

Background:All endodontic instrumentation systems tested so far, promote apical extrusion of debris, which is one of the main causes of postoperative pain, flare ups, and delayed healing.Objectives:Of this meta-analysis was to collect and analyze in vitro studies quantifying apically extruded debris while using Hand ProTaper (manual), ProTaper Universal (rotary), Wave One (reciprocating), and self-adjusting file (SAF; vibratory) endodontic instrumentation systems and to determine methods which produced lesser extrusion of debris apically.Methodology:An extensive electronic database search was done in PubMed, Scopus, Cochrane, LILACS, and Google Scholar from inception until February 2016 using the key terms “Apical Debris Extrusion, extruded material, and manual/rotary/reciprocating/SAF systems.” A systematic search strategy was followed to extract 12 potential articles from a total of 1352 articles. The overall effect size was calculated from the raw mean difference of weight of apically extruded debris.Results:Statistically significant difference was seen in the following comparisons: SAF < Wave One, SAF < Rotary ProTaper.Conclusions:Apical extrusion of debris was invariably present in all the instrumentation systems analyzed. SAF system seemed to be periapical tissue friendly as it caused reduced apical extrusion compared to Rotary ProTaper and Wave One.

dimensional obturation. During the process, the debris of the root canal system is pushed out from the canals, leading to treatment failure and flare-ups. 1 Many factors contribute to debris extrusion. According, 2 irrigation of the root canal space during instrumentation is one of the factors that led to an increased amount of debris extrusion. Teeth with necrotic pulp permitted more irrigant extrusion compared with vital teeth. The depth of file insertion into the root canal is another factor affecting debris extrusion. Studies conducted 3,4 showed that instrumentation short of apical foramen decreased the amount of debris extrusion with both endosonic and k-files. Canal preparation done with step-back techniques showed greater amount of periapical extrusion, whereas canal preparation having special design of nickel-titanium files with crown-down technique decreases the amount of extrusion periapically.2 The amount of apical extrusion can also vary according to the technique used. It is generally accepted that instrumentation techniques that incorporate rotational action generate less debris than push/ pull instrumentation, and the crown-down technique has been associated with the least amount of debris extrusion, compared with techniques involving a linear filing motion. Thus, engine-driven rotary systems have tended to extrude less debris than hand techniques. Recently, newer file system WaveOne Gold has been introduced, which was compared with F360, One Shape, and Reciproc.The Reciproc files are composed of M-Wire nickeltitanium, which offers increased flexibility. The reciprocating movement of the instrument reduces the risk of cyclic fatigue.One Shape files, on the contrary, employ traditional continuous rotation. They have a triangle-shaped cutting edge and two additional cutting edges, in the apical and coronal parts, as well as a cross-section that progressively changes from three to two cutting edges between the apical and coronal parts. This design offers optimal cutting action. 1,3 F360 has a double S-shaped cutting edges and a lower bending ability increasing the flexibility of file. It has a ABSTRACTIntroduction: Root canal therapy comprises three main steps, namely access preparation, biomechanical preparation, and three-dimensional obturation. During the process, the debris of the root canal system is pushed out from the canals, leading to treatment failure and flare-ups.

“…Estos sistemas presentan características similares en el diseño de la sección transversal del instrumento, una forma de S itálica, de poca masa, con márgenes de corte afilados, lo que les confiere una eficacia de corte y porcentaje de extrusión similar (Bürklein & Schäfer;Caviedes-Bucheli et al, 2018). Estudios previos concluyeron que el diseño del instrumento y el tipo de movimiento, presentan más relevancia que la cantidad de instrumentos utilizados, al evaluar el grado de extrusión apical entre sistemas de movimiento recíproco y rotatorio (Tinoco et al, 2014;Xavier et al, 2015;Silva et al, 2016a,b;Uzun et al, 2016).…”

RESUMEN: El barro dentinario producido durante tratamiento endodóntico puede ser extruido hacia el tejido periradicular junto con el irrigante, produciendo inflamación y dolor postoperatorio. Comparar la cantidad de extrusión apical de barro dentinario e irrigante, producido durante la preparación químico-mecánica, por dos sistemas de instrumentación Rotatoria (Mtwo), y Reciprocante (Reciproc), complementado con irrigación pasiva o activa (Endoactivator). Cuarenta y ocho premolares (48) inferiores, fueron aleatoriamente distribuidos en cuatro grupos de estudio (n=12 dientes), (1) Rotatorio-pasiva, (2) Reciprocante-pasiva, (3) Rotatorio-activa y (4) Reciprocante-activa. Los conductos radiculares fueron instrumentados de acuerdo a las instrucciones del fabricante, e irrigados con hipoclorito de sodio al 5 %. El barro dentinario e irrigante extruido, fueron recolectados en tubos Eppendorf previamente pesados. Se calcularon los valores de extrusión de barro dentinario e irrigante para cada grupo. Los datos fueron analizados con el análisis de varianza ANOVA. En todos los grupos se produjo extrusión apical. No se encontraron diferencias estadísticamente significativas en la extrusión apical de barro dentinario, entre los grupos estudiados (P = 0,068), sin embargo, al analizar la extrusión de irrigantes, se evidenció diferencia estadísticamente significativa entre los grupos 1 y 4 (P< 0,05), entre los demás grupos no se observaron diferencias estadísticamente significativas. (P > 0,05). Bajo las condiciones de este estudio, los sistemas rotarios y reciprocante, extruyen sólido y líquido, siendo el sistema reciprocante el que produce mayor extrusión de líquido, tanto con irrigación activa como pasiva. PALABRAS CLAVE: extrusión apical, barro dentinario, instrumentación mecanizada. * Indica grupos significativamente diferentes (p <0,05).
