In this study, residual apical microlumina remaining after obturation with five different gutta-percha obturation methods were traced with an efficient vacuum method. Seventy-nine human maxillary anterior teeth were instrumented and divided into five groups. The groups were obturated with single-cone techniques, lateral condensation, vertical condensation,(More)
A new glass ionomer root canal sealer (Ketac-Endo) has been developed. The purpose of this study was to compare the apical leakage of Ketac-Endo and AH26 using two different filling techniques and a controlled vacuum procedure. Sixty-four extracted human maxillary anterior teeth were instrumented and divided into four groups of 15 roots each. The groups(More)
The histological response of periapical tissues to root canal fillings with Sealapex, pure calcium hydroxide and gutta-percha points was studied in dogs' teeth. After pulpal extirpation the root canals were enlarged, irrigated and dried. Teeth in the first group were filled with gutta-percha points alone, those in the second group were filled with pure(More)
Objective. The purpose of this study was to compare the placement techniques of Ca(OH)(2). Study Design. Forty simulated curved canals (42 degrees) in transparent resin blocks were used and separated into 4 experimental groups, 10 canals each. A paste of Ca(OH)(2) was mixed with either water or glycerin and placed into canals with Lentulo spiral or(More)
The purpose of this in vitro study was to examine the coronal leakage of canals medicated with Ca(OH)(2) compared with the canals which did not receive Ca(OH)(2) medication before obturation with laterally condensed gutta-percha points and sealer. Sixty-one single rooted permanent canines and premolars were used. The crowns were removed from the(More)
The effect of post canal preparation on the apical seal of endodontically obturated teeth with plastic Thermafil obturators was studied in vitro. Fifty-four extracted human maxillary anterior teeth were divided into four experimental and two control groups. Two groups were obturated with lateral condensation or plastic Thermafil obturator techniques; this(More)
AIM To evaluate the solubility of five different root canal sealers (AH Plus Jet, RealSeal SE, MTA Fillapex, Tubli-Seal, and Acroseal) in chloroform, eucalyptol and Endosolv-E solvents. MATERIALS AND METHODS Ninety root canal sealer samples were prepared and then divided into three groups for immersion in a solvent for 2, 5 or 10 minutes. The mean values(More)
In this study, dentinal penetration and adaptation of three endodontic sealers were evaluated by using scanning electron microscope (SEM). Seventeen recently extracted, human maxillary anterior teeth were used. After the crowns were removed from the cementoenamel junction, the root canals were instrumented. The teeth were then randomly divided into three(More)
