in vitro comparison of apical leakage in root canals obturated with 0.04 and 0.02 tapered gutta-percha

In vitro comparison of apical leakage in root canals obturated with 0.04 and 0.02 tapered gutta-percha

INTRODUCTION Gutta-percha is the most commonly used material for root canal obturation; it has been recently manufactured with different tapers. The aim of this in vitro study was to compare microleakage of canals obturated with standard gutta-percha (0.02 taper) or the new 0.04 taper gutta-percha master cone using the cold lateral condensation technique. MATERIALS AND METHODS Forty-four extr...

Effect of Different Tapered Gutta Percha Cones in Apical Microleakage of Human Root Canal Obturation

Background and purpose: Gutta-percha is generally accepted as the main canal filler. Standard gutta-percha cones are available in 2-10% tapers. The purpose of this study was to compare apical microleakage of canals obturated with different tapers of gutta-percha, using the protein penetration technique. Materials and methods: In this study, 96 maxillary anterior teeth were selected and were pr...

In vitro comparison of gutta-percha-filled area percentages in root canals instrumented and obturated with different techniques

PURPOSE To evaluate the efficacy of different obturation techniques in root canals instrumented either by hand or rotary instruments with regard to the percentage of gutta- percha-filled area (PGFA). MATERIALS AND METHODS One hundred and sixty extracted mandibular premolars with single, straight root canals were studied. Root canals were prepared to an apical size of 30 by hand with a modifie...

Comparing Microleakage in Root Canals Obturated with Nanosilver Coated Gutta-Percha to Standard Gutta-Percha by Two Different Methods

INTRODUCTION Favorable apical seal of root filling materials is a crucial factor for a successful root canal treatment. The aim of this in vitro study was to compare bacterial and dye microleakage of two root canal filling materials including standard gutta-percha and nanosilver coated gutta-percha, and to evaluate the agreement between results of these two methods. MATERIALS AND METHODS Fift...

In vitro evaluation of root canals obturated with four different techniques. Part 2: apical leakage.

Retreatability of Root Canals Obturated Using Gutta-Percha with Bioceramic, MTA and Resin-Based Sealers

INTRODUCTION The aim of this study was to evaluate the retreatability of root canals obturated with gutta-percha (GP) and three different endodontic sealers [iRoot SP (bioceramic sealer), MTA Fillapex (MTA-based sealer) and AH-26 (epoxy resin-based sealer)] using the ProTaper Universal Retreatment (PTR) system. METHODS AND MATERIALS Forty extracted single-rooted human teeth were prepared with...
