INTRODUCTION To compare the apical extrusion of debris produced during root obturating material removal from severely curved root canals using either Reciproc (REC) or ProTaper Next (PTN) systems. METHODS AND MATERIALS Twenty-six mesial canals of lower molars were instrumented, filled and allocated into two groups (n=13). Micro-computed tomographic images were performed to determine the root ...

CONTEXT Conjunctivodacryocystorhinostomy (CDCR) is the procedure of choice for proximal canalicular blocks. However, the complications of tube migration and extrusion limit its widespread practice. AIM The aim of this study is to evaluate the efficacy and complications of the new "mirror tuck technique" for fixation of lacrimal bypass glass tube without holes in proximal canalicular blocks in...

An 11 months old male child, with congenital HCP presented extrusion of shunt tube form the anus after defecation. He was managed by VP 8 back; 6 later lower end revised for obstruction. Lower exteriorized and distal cut pulled out per rectally. Later ETV done patient discharged uneventfully.Key words: Shunt, Trans anal, Extrusion, Management, Outcome. Bang.

The outcome of otitis media with effusion (OME) in children is generally good. However, it is less clear in adults. All adult patients who had a ventilation tube inserted for OME at the Ipswich Hospital between 1996 and 1997 were studied. Of 53 patients studied, 28 had had a previous history of ventilation tube insertion. Furthermore, at 15-27 months following ventilation tube insertion, the ve...

In material extrusion (MatEx) additive manufacturing, solid polymer filaments are fed into extruders to generate extrudates that needed build 3D plastic parts. There is a finite gap between the inner surface of an extruder and edge filament, which facilitates insertion translation filament inside extruder. It still not clear how this filled during extrusion. On other hand, it important know inf...

The extrusion apparatus of the microsporidian parasitic protozoan Nosema michaelis discharges an invasion (or polar) tube with a velocity suitalbe for piercing cells and injecting infective sporoplasm. The tube is composed of a polar tube protein (PTP) which consists of a single, low molecular weight polypeptide slightly smaller than chymotrypsinogen-A. Assembled PTP tubes resist dissociation i...

BACKGROUND The aim of the present study was to compare the effect of ultrasonically or laser (Nd:YAG or diode) activated irrigation on the irrigating solution extrusion compared to non-activated syringe irrigation. METHODS Extracted mandibular premolar teeth (n = 48) with single canals were instrumented. The teeth were secured through the lid of an Eppendorf tube filled with 1.0 mL distilled ...
