CFD analysis on the effect of combining positive and negative pressure during the irrigation of artificial isthmuses
Loroño Goikoetxea, Gaizka; Rodríguez Zaldívar, José Manuel; Jiménez Octavio, Jesús Ramón; Dorado Nuño, Saúl Manuel; Arias Paniagua, Ana María; Cisneros Cabello, Rafael (2020-10-01)Fluid dynamics generated by irrigation needles have not been deeply analyzed in root canal irregularities such as apical ramifications or isthmus where the cleaning capacity of irrigants might be compromised and hence the ... -
Positive and negative pressure irrigation in oval root canals with apical ramifications: a computational fluid dynamics evaluation in micro-CT scanned real teeth
Loroño Goikoetxea, Gaizka; Rodríguez Zaldívar, José Manuel; Arias Paniagua, Ana María; Cisneros Cabello, Rafael; Dorado Nuño, Saúl Manuel; Jiménez Octavio, Jesús Ramón (2020-05-01)Aim To compare with computational fluid dynamics (CFD) the flow pattern, irrigant velocity, apical pressure and shear stress produced by negative (MiC) and positive pressure with different types of needles (side-vented ...
