Comparison between the use of thermoplasticized gutta-percha and a polydimethyl siloxane-based material in filling internal resorptive cavities using spiral computed tomography.

Numai utilizatorii înregistrați pot traduce articole

To evaluate the fill of internal resorption cavities obturated with thermoplasticized gutta-percha and GuttaFlow2 using CT scan. Twenty human maxillary anterior teeth were selected and root canals were prepared using ProTaper system to size F3. Irrigation was performed with 5 ml of 2.5% sodium

Quality of different gutta-percha techniques when filling experimental internal resorptive cavities: a micro-computed tomography study.

Numai utilizatorii înregistrați pot traduce articole

The purpose of this ex vivo study was to determine the quality of root fillings in experimental internal resorptive cavities filled using cold lateral condensation (CLC), vertical condensation and Thermafil techniques. Forty-five extracted maxillary canine teeth were selected. After root canal

Effectiveness of different gutta-percha techniques when filling experimental internal resorptive cavities.

Temperature changes in gutta-percha and Resilon cones induced by a thermomechanical compaction technique.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND The aim of this study was to assess temperature changes in conventional gutta-percha, thermoplastic gutta-percha, and Resilon cones by using thermomechanical compaction technique. METHODS The root canals of extracted human teeth were placed in resin blocks and sectioned. After root canal

Efficacy of rotary and reciprocating single-file systems on different access outlines for gutta-percha removal in retreatment: An in vitro study.

Numai utilizatorii înregistrați pot traduce articole

UNASSIGNED The aim of this study is to compare the effectiveness of reciprocating and continuous rotary nickel-titanium instruments during retreatment performed through two different access outlines. UNASSIGNED A total of 48 freshly extracted mandibular first and second premolars with single root

Effect of various sealers with gutta-percha as root-end fillings on healing after replantation.

Numai utilizatorii înregistrați pot traduce articole

This study examined histologically the effect of three sealers used with gutta-percha as root-end fillings placed in a replantation model. A total of 14 molar teeth were used in seven monkeys. After extraction, root ends were resected, the canals contaminated with oral bacteria, root-end cavities

Effect of cavity varnish and intermediate restorative material on coronal microleakage in endodontically treated tooth.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Evaluation of microleakage in endodontically treated teeth that have been coronally sealed with eugenol and noneugenol containing zinc oxide cement, with and without the use of cavity varnish. METHODS The crowns of single rooted teeth were removed at the cementoenamel junction (CEJ) and

A comparison of the sealing ability of various temporary restorative materials to seal the access cavity: An in vitro study.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND In multiple-appointment root canal treatment, a temporary filling material is used to seal the access cavity between visits. The primary function of this material is to prevent the contamination of the root canal system by fluids, organic debris, and bacteria from the oral

Sealing efficacy of a zinc oxide-eugenol cement, a cyanoacrylate, and a cavity varnish used as root canal cements.

Numai utilizatorii înregistrați pot traduce articole

Forty single-rooted human central incisor teeth were biomechanically instrumented. Thirty teeth were divided into three groups of 10 and obturated with laterally condensed gutta-percha and one of three cementing mediums. These were zinc oxide-eugenol root canal cement, cyanoacrylate, and cavity

Comparison of resilon and gutta-percha filling materials on root canal fracture resistance following restoring with quartz fiber posts.

Numai utilizatorii înregistrați pot traduce articole

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

Microleakage of endodontic access cavities restored with composites.

Numai utilizatorii înregistrați pot traduce articole

A proper seal of restorative composites in endodontic access cavities is mandatory to prevent ingress of microorganisms and debris into the tooth-restoration interface. Chemically cured composites tend to have less polymerization shrinkage than photopolymerization composites. This study compared in

[Antibacterial effect of the materials for the root canal filling, bases and material for the cavity fillings].

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE To assess antimicrobial effects of the materials used in the endodontic treatment of the teeth. METHODS The following root-canal fillings were examined: Ketac Endo, AH Plus, Diaket, and gutta-percha, by means of the agar diffusion test. As for the base materials, Zink Oxide/Eugenol cement,
