The Effect of Disruption of Apical Constriction on Periapical Extrusion

Journal of Endodontics, 2005
The aim of this study was to compare the amount of apical extrusion during manual instrumentation and engine-driven rotary instrumentation in teeth with disrupted apical constriction. Fifty-two teeth were divided into two groups comprising 26 teeth each.

Evaluation of 4 Different Irrigating Systems for Apical Extrusion of Sodium Hypochlorite

Journal of Endodontics, 2015
The aim of this study was to evaluate NaOCl apical extrusion by using negative apical pressure (EndoVac), sonic agitation (EndoActivator), side-vented needle (Max-i-Probe), and photon induced photoacoustic streaming (PIPS 10 mJ and PIPS 20 mJ) laser irrigation in an in vitro gel model.Extracted mandibular and maxillary central incisors (n = 18) were ...

Effect of different apical actions of new integrated endodontic motors on apical debris extrusion: An in vitro study

Australian Endodontic Journal, 2023
AbstractThe new generation endodontic motors can perform different kinematics when they reach a certain predetermined level thanks to the integrated apex locator system. These actions consist of apical reverse, apical slow down and apical stop. The aim of this study is to compare this action's effect on apical debris extrusion.

Assessment of Apical Extrusion During Root Canal Irrigation With the Novel GentleWave System in a Simulated Apical Environment

Journal of Endodontics, 2016
This study assessed apical extrusion during treatment with GentleWave (GW; Sonendo Inc, Laguna Hills, CA), a conventional open-ended 30-G needle (CN), or Endovac (EV; SybronEndo, Orange, CA) in root canals enlarged to different dimensions with and without apical constriction.Sixteen mandibular molars were mounted in an in vitro apparatus.

Influence of working length and apical preparation size on apical bacterial extrusion during reciprocating instrumentation

International Endodontic Journal, 2014
AbstractAimTo evaluate the influence of reciprocating single‐file instrumentation with different working lengths (WL) and apical preparation sizes on apical bacterial extrusion.MethodologySixty‐eight human single‐rooted pre‐molars were used. Conventional access cavities were prepared, and the root canals were contaminated with an Enterococcus faecalis ...

Extrusion of lysosomal bodies from apical mouse retinal pigment epithelium

Albrecht von Graefes Archiv f�r Klinische und Experimentelle Ophthalmologie, 1981
The retinal pigment epithelium (RPE) of 1- 24-month-old CF-1 mice was examined by both light and electron microscopy. Measurement of the area occupied by lysosomal bodies was carried out using a semiautomatic quantitative picture analyzing system (Kontron-EKO).
