Bidirectional multiciliated cell extrusion is controlled by Notch-driven basal extrusion and Piezo1-driven apical extrusion. [PDF]
Development, 2023 Abstract Xenopus embryos are covered with a complex epithelium containing numerous multiciliated cells (MCCs). During late stage development there is a dramatic remodeling of the epithelium that involves the complete loss of MCCs.

Apical extrusion of debris by manual and mechanical instrumentation [PDF]
Brazilian Dental Journal, 2007 The aim of the present study was to assess the presence of apically extruded debris and evaluate the influence of canal curvature on the amount of debris produced by manual and mechanical techniques. Forty single-rooted mature teeth with 15 to 30 degree of root canal curvature were selected.

Severe Extrusion from an Apical Abscess: A Case Report
Dental Update, 2004 A 10-year-old boy presented with an acute apical abscess with extensive extrusion of a maxillary central incisor. The tooth, the maxillary right central incisor, had a history of trauma and subsequent apical abscesses. This article describes the presentation, management of the abscess and the subsequent results of treatment.

Live Imaging of Apoptotic Extrusion and Quantification of Apical Extrusion in Epithelial Cells. [PDF]
Bio Protoc, 2021 Apoptotic cell death eliminates unhealthy cells and maintains homeostatic cell numbers within tissues. Epithelia, which serve as fundamental tissue barriers for the body, depend on a physical expulsion of dying cells (apoptotic cell extrusion) to remain sealed and intact.

Apical extrusion of debris using reciprocating files and rotary instrumentation systems [PDF]
Nigerian Journal of Clinical Practice, 2016 To compare the preparation time and amount of apically extruded debris after the preparation of root canals in extracted human teeth using the reciprocating files and rotary nickel-titanium systems.Sixty extracted human mandibular premolars were used. The root canals were instrumented using reciprocating (WaveOne, Reciproc, SafeSider) or rotary motion (

Apical Extrusion of Debris Produced during Continuous Rotating and Reciprocating Motion [PDF]
The Scientific World Journal, 2015 This study aimed to analyse and compare apical extrusion of debris in canals instrumented with systems used in reciprocating and continuous motion. Sixty mandibular premolars were randomly divided into 3 groups (n=20): the Reciproc (REC), WaveOne (WO ...

Relationship between the size of patency file and apical extrusion of sodium hypochlorite
Indian Journal of Dental Research, 2009 Background: Sodium hypochlorite (NaOCl) is the most widely used endodontic irrigant because of its excellent antimicrobial, organic tissue dissolving, and lubricating properties. However, it is highly cytotoxic to the periapical tissues.

Plectin is a novel regulator for apical extrusion of RasV12-transformed cells. [PDF]
Sci Rep, 2017 AbstractSeveral lines of evidence have revealed that newly emerging transformed cells are often eliminated from the epithelium, though the underlying molecular mechanisms of this cancer preventive phenomenon still remain elusive. In this study, using mammalian cell culture systems we have identified plectin, a versatile cytoskeletal linker protein, as ...

Influence of Apical Patency and Cleaning of the Apical Foramen on Periapical Extrusion in Retreatment [PDF]
Brazilian Dental Journal, 2013 This study evaluated the influence of apical patency, root filling removal technique and cleaning of the apical foramen, concerning the amount of debris extruded during root canal retreatment. Forty mandibular incisors were randomly assigned to 4 groups - GIM (n=10), GIIM (n=10), GIPT (n=10) and GIIPT (n=10), which were named according to leaving (I ...
