The aim of this study was to evaluate the in vitro obturation quality of four filling methods: active lateral condensation, a modification of Tagger's hybrid technique, ENAC ultrasound technique and the Microseal technique. The study was performed on one hundred and sixteen single-rooted human teeth, divided into four groups of twenty nine teeth, embedded in resin, longitudinally sectioned and ...

The objective of this study was to compare the sealing ability of ActiV GP/glass ionomer (GI) sealer (Brasseler USA, Savannah, GA), Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT), and gutta-percha (GP)/AH Plus (Dentsply Maillefer, Tulsa, OK). Seventy-three human single-rooted teeth were randomly divided into three test groups (20 canals each) and two control groups (5 positiv...

AIM To compare the apical seal of lateral condensation technique, thermafil and one-step by using this model. MATERIALS AND METHODS A two-chamber bacterial microleakage model using E. faecalis as microbial marker was used for evaluation of the leakage. Bacterial penetration was monitored over a 60-day period. Leakage was recorded when turbidity was observed in the lower chamber. RESULTS Aft...

endoscopic retrograde cholangiopancreatography (ercp) is a specific technique used to study the pancreatobiliary system that is performed in hepatogastroenterology centers. recent, common uses for therapeutic ercp are largely due to advanced imaging techniques such as magnetic resonance cholangiopancreatography and endosonography. in the united states alone, over 500,000 therapeutic ercp are pe...

aim : the aim of this study was to analyze clinical findings and treatment outcomes of patients with endoscopic retrograde cholangiopancreatography complications. background : endoscopic retrograde cholangiopancreatography has become a very common procedure for the evaluation and treatment of biliary and pancreatic diseases. patients and methods : a retrospective review of 2447 endoscopic retro...

Rotary instrumentation has been proposed in undergraduate teaching. The aim of this study was to evaluate student’s performance, through the obturation quality and treatment time, a sequential range L-simulated root canals. A senior dental student sequentially prepared randomly numbered canals from 1 40, with WaveOne Gold glider primary file, according manufacturer instructions. gutta-percha co...
