INTRODUCTION The aim of this study was to compare the sealing ability of Real Seal (RS) and Gutta-percha (GP). MATERIALS AND METHODS Forty nine extracted human maxillary central incisors were used. The coronal part of each tooth was removed, the root canal was prepared using the crown down technique and apical enlargement to rotary file # 40. The specimens were randomly divided in to 3 groups...

d f n w u t 3 E w M c a s c g bstract his study compared the remaining filling material and orking time when removing gutta-percha/AH 26 and esilon/Epiphany from root filled extracted teeth. The oot fillings were removed using chloroform and two ifferent rotary systems (K3 and Liberator files). The mount of residual filling material on the canal walls as imaged and measured using image analyzer...

Aim: Most endodontic sealers show antimicrobial activity before setting, but most of them also lose this ability after setting. Addition of an antibiotic may affect the properties of sealers such as sealing ability, setting time, and so on. The aim of this study was to assess whether the addition of antibiotics (amoxicillin, doxycycline, and clindamycin) improves the sealing ability of AH 26 se...

a mandibular second premolar with four canals is an interesting example of anatomic variations. this report describes a case of a mandibular second premolar with three roots and four canals (one mesiobuccal, two distobuccal and one lingual). the canals were prepared using k-files and irrigated with naocl (5.25%) and normal saline as the final irrigant. the canals were filled laterally with gutt...

AIM The study was designed to quantitatively evaluate the quality of root canal preparation and root canal obturation in canals treated with either rotary or self adjusting files, using three-dimensional micro-computed tomographic (CT) analysis. METHODOLOGY Pair-matched root canals were instrumented with either rotary nickel-titanium files or self-adjusting files following the manufacturers' ...

OBJECTIVES The aim of this study was to compare apical sealing ability of alpha and beta phases of gutta-percha by means of bacterial leakage model. MATERIALS AND METHODS Fifty single-rooted human premolars were selected. The root canals were prepared with Mtwo rotary instruments up to apical #35.04. Forty teeth were randomly divided into two groups (n= 20). The root canals were obturated by ...

OBJECTIVE Contradictory results have been reported over microleakage studies of restorative materials and methods. Despite the number of publications on leakage there are few evidences comparing the different microleakage evaluation methods. The purpose of the present study was to compare the clearing technique and longitudinal sectioning in the evaluation of dye penetration along a glass fiber...

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...

The aim of this study was to evaluate in vitro the duration of the antimicrobial effect of endodontic sealers by means of the Direct Contact Test. The sealers tested were: Endomethasone - Septodont, Endomethasone C-Septodont, Endion-Voco, Diaket-ESPE, Pulp Canal Sealer-SybronEndo, and AH26-Dentsply DeTrey. The endodontopathic microorganisms (MO) confronted were: Staphylococcus aureus (Sa), Cand...
