background: endodontic leakage research focus mainly on the quality of the apical seal of the root canal system and the newly introduced resilon/epiphany system claim to be superior to gutta-percha in respect to obturation procedure. the aim of this study is to evaluate the root canal obturation completed by resilon/epiphany system. materials and methods: a total of 42 teeth were selected and w...

BACKGROUND As per many studies endodontically treated teeth are widely considered to be more susceptible to fracture than vital teeth. Obturation strains and post placement have been a major cause of vertical root fracture. Present study was conducted to compare in vitro fracture resistance after filling with either Gutta-percha or Resilon by lateral condensation techniques in root canals. This...

to compare the mechanical properties of resilon and gutta-percha cones after storing at three different temperatures.one-hundred standardized size 40/02 gutta-percha cones and 100 resilon cones were randomly divided into four groups. the first group of the materials were tested immediately after receipt as the control group. the other three were stored in their packages at -12°c, 4± 1°c and 22±...

objective: application of chemical solvents especially in problematic canals is usually a part of the retreatment process.this study was performed to compare the solubility of gutta- percha and resilon in chloroform and to find the effect of sample thickness as well as the time of shaking on their solubility. materials and methods: specific weight of resilon and gutta-percha was placed in a sam...

OBJECTIVES Cytotoxic effects of obturation materials were tested in presence and absence of endotoxin on human monocytes in vitro. MATERIALS AND METHODS Human monocytes from THP-1 cell line were cultured. Three millimeters from the tip of each Resilon and gutta percha points were cut and directly placed at the bottom of the culture wells. Cultured cells were exposed to gutta percha (groups G1...

AIM To compare the long-term apical sealing ability of gutta-percha/AH Plus and Resilon/Epiphany. METHODOLOGY The root canals of 90 single-rooted human mandibular premolars with single narrow root canals were prepared with ProFile 0.4 taper instruments to apical size 40. After each instrument, the canals were irrigated with 1% sodium hypochlorite. Subsequently, the teeth were randomly divided...

The aim of this study was to evaluate the effectiveness of gutta-percha and Resilon in filling lateral root canals by using the Obtura II system. Root canals of artificial teeth were prepared using a standard protocol, and lateral canals were made in three thirds of the root canal. The root canals were filled with either Obtura gutta-percha (OB), Endo-points flow gutta-percha (ED), or Resilon (...

Background/Aim. During retreatment, filling material and debris may extrude trigger an inflammatory reaction of periapical tissues. Resilon? has not been investigated in terms solvent use influence on apical extrusion during retreatment. The aim the study was to evaluate amount apically extruded removal using ProTaper (PT), Twisted File (TF), Hedstrom instruments, with without solvent. Methods....

The aim of this study was to evaluate the effectiveness of 3 solvents (eucalyptol, orange oil, and xylol) on 2 types of gutta-percha (conventional and thermoplastic) and Resilon. Specimens (10 mm diameter x 1 mm thick; n=7 per condition) were prepared and maintained at 37 degrees C for 48 h. Each specimen was weighed on a precision scale every 24 h until its mass was stable, at which time the i...

OBJECTIVE Bacterial leakage and root fractures are the most important reasons of root canal treatment failure. Due to the lack of adhesion of gutta percha to the canal walls, Resilon has been introduced as a root-filling material able to bond to the root walls. Metal posts may predispose the tooth walls to oblique and vertical fracture which usually leads to tooth loss; whereas, fiber posts may...
