AIM To examine formaldehyde release from three different root-canal sealers: one phenol resin, one epoxy resin and one paraformaldehyde containing zinc oxide eugenol cement. METHODOLOGY Formaldehyde was measured from freshly mixed material and from specimens allowed to set for 2 days or 2 weeks. Different mixing ratios and sample sizes were tested. Analysis was performed by reacting formaldeh...

OBJECTIVE This study evaluated the effect of two different eugenol-based root canal sealers on the retention of prefabricated metal posts luted with adhesive resin cement. MATERIALS AND METHODS Thirty prefabricated ParaPosts randomly divided among three groups of 10 each were luted into extracted single-rooted teeth with adhesive resin cement. Two of the groups had been obturated with Gutta-P...

BACKGROUND The aim of this study was to quantitatively analyze the amount of dye leakage with AH26, Sealapex and Tubliseal sealers in endodonticaly treated teeth. MATERIALS AND METHODS A total of 36 extracted mandibular molar specimens were divided into three groups; Group I: Sealapex, Group II: Tubliseal, Group II: AH26 with 12 samples in each group. Standard access cavity and biomechanical ...

Aim This laboratory study evaluated the pH and antibacterial activity of Endo CPM Sealer and MTA Fillapex by two different methods, using White MTA and Endofill as references for comparison. Methodology Antibacterial activity was evaluated against Enterococcus faecalis (ATCC 29212). The agar diffusion test (ADT) was performed to evaluate the effect before setting. The materials were placed in f...

BACKGROUND The aim of the present study was to compare in vitro the antimicrobial activity of different root canal sealers against Enterococcus faecalis, prior and subsequent to setting. MATERIAL AND METHODS Agar diffusion test (ADT) was used for evaluating the antibacterial activity of non-set sealer while the direct contact test (DCT) was used for after setting. RESULTS ADT: Except for To...

Aim. To evaluate the antibacterial activity of four endodontic sealers on Enterococcus faecalis by a direct contact test. Material and Methods. Enterococcus faecalis was used as a test organism. Direct contact test which is based on measuring the effect of close contact between test bacteria and tested material on the kinetics of bacterial growth was performed to overcome the disadvantages of a...

This in vitro study aimed to determine the susceptibility of oral specimens and ATCC lineages of Candida albicans for five endodontic sealers, which were pure and associated with two antifungal drugs, and to analyze their effect on the physical properties. For this purpose, 30 lineages of C. albicans, collected from the oral cavity of patients assisted at the endodontics clinic of the Universid...

INTRODUCTION Microorganisms and microbial products are the main etiologic factors in pulp and periapical diseases. The present study aimed to compare the antifungal activity of two different sealers, AH-26 and MTA Fillapex against three strains of Candida, 24, 48, 72 h and 7 days after mixing. METHODS AND MATERIALS The microorganisms used in this study were Candidia albicans (ATCC 10231), Can...

The aim of this study was to evaluate the filling effectiveness and dentinal penetration of the sealers AH Plus, Pulp Canal Sealer EWT, Sealapex and MTA Fillapex applied according to the vertical condensation technique using thermoplastic gutta-percha. Forty single-rooted teeth were selected. After chemical-mechanical preparation and root-canal filling, sections of the root (2, 4 and 6 mm from ...

The efficacy of ultrasonic retreatment, 3 months after obturation, in conjunction with Ketac-Endo, Roth's 801, and AH26 sealers was evaluated. Seventy-two root canals were prepared and obturated with gutta-percha and one of the sealers mentioned above. After 90 days, the canals were retreated by an ultrasonic technique and the retreatment time was recorded. The roots were split and the amount o...
