Syringe irrigation in confluent canals: A sequential computational fluid dynami...
Rito Pereira, Mário; Silva, Goncalo; Semiao, Viriato; Martins, Jorge; Silverio, Vania; Pascoal-Faria, Paula; Duarte, Isabel; Alves, NunoThis study aims to assess the influence of root canal preparation, irrigation needle design and its placement depth in the irrigation flow of confluent canals during syringe irrigation. A mandibular molar presenting two confluent canals in its mesial root was sequentially prepared and scanned by micro-computed tomography after mechanical preparation up to ProTaper Next system sizes X2 (25/.06v), X3 (30/.07v) an...

Pereira, Mário; Silva, Gonçalo; Semiao, Viriato; Silverio, Vania; Martins, Jorge; Pascoal-Faria, Paula; Alves, Nuno; Dias, Juliana; Ginjeira, AntónioThis study aimed to experimentally validate a computational fluid dynamics (CFD) model, using micro-particle image velocimetry (micro-PIV) measurements of the irrigation flow velocity field developed in confluent canals during irrigation with a side-vented needle. A microchip with confluent canals, manufactured in polydimethylsiloxane was used in a micro-PIV analysis of the irrigation flow using a side-vented n...
