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
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
OBJECTIVE
To determine the quality of root fillings in teeth with artificial internal resorptive cavities filled with Thermafil, JS Quick-Fill, Soft Core, System B and Microseal, and by cold lateral compaction (LC) technique.
METHODS
Sixty maxillary incisor teeth were selected. After access cavity
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
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
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
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
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
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
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
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
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,
