This project was designed to determine how a new resin based obturation material compared with traditional gutta-percha techniques in its ability to fill the prepared root canal space. Eighty single-rooted palatal and distal roots of extracted human first molars were used. The root canals were instrumented with hand and rotary files and divided into four groups. Gutta-percha and the new resin b...

AIM The aims of this study were firstly to compare the area of canal occupied by gutta-percha, sealer or voids using the System B heating device with that obtained by a modified vertical condensation technique using the Touch 'n Heat: and secondly to compare the temperature changes at the root canal wall and external root surface during obturation with the above techniques. METHODOLOGY Forty-...

OBJECTIVE The aim of this study was to compare the presence of voids in root fillings performed in oval and ribbon-shaped canals with two root filling techniques, lateral compaction technique (LCT) or hybrid technique (HT), a combination of a gutta-percha masterpoint and thermoplastic gutta-percha. Furthermore, the obturation time for the two techniques was evaluated. MATERIALS AND METHODS Si...

Three clinical cases involving teeth with open apices and apical periodontitis were treated using different protocols. The first case was managed with intracanal calcium hydroxide paste for 12 months before obturation with gutta-percha and sealer. In the second case, an apical plug of mineral trioxide aggregate (MTA) was used before obturation with gutta-percha and sealer and treatment was comp...

an important goal in endodontic treatment. To achieve this goal, the root canal filling must seal the pulp space both apically and laterally to prevent further apical irritation from incomplete elimination of bacterial products.1 In the past, the adequacy of root canal filling procedure was primarily based on its vertical appearance on the dental radiograph and whether the material had reached ...

Background and aims. Various materials and methods have been introduced for obturating cleaned and shaped root canal systems. This in vitro study aimed to evaluate the sealing ability of single-cone obturation technique with mineral trioxide aggregate and calcium-enriched mixture based on bacterial leakage approach. Materials and methods. Sixty-four single-canal teeth were prepared and randomly...

OBJECTIVES The goal of this study was to compare the density of gutta-percha root fillings obturated with the following techniques: cold lateral (CL) compaction, ultrasonic lateral (UL) compaction, and warm vertical (WV) compaction. MATERIALS AND METHODS Thirty-three extracted mandibular first molars, with two separate mesial canals in each, were selected. After instrumentation, the canals we...

A split-tooth model with artificially created intracanal wall defects was used to compare three gutta-percha (GP) obturation techniques, cold lateral, warm lateral, and warm vertical. The techniques were evaluated and compared based on defect replication quality as a function of defect location and size. The obturations were evaluated on an ordinal scale, 0 to 4, based on how much each defect w...

The aim of this study was to examine and compare vertical forces exerted during root canal obturation with the cold lateral condensation technique, Thermafil technique and ProTaper guttapercha. Fourty-five single-rooted permanent teeth were used in the study. All specimens were instrumented using the ProTaper rotating technique and were randomly divided into three experimental groups (n = 15 pe...
