Since there are no data in the literature regarding comparison of marginal adaptation hydraulic sealers when used with a single-cone technique or through thermomechanical compaction, this study aimed to evaluate behavior four different endodontic two above-mentioned obturation techniques by evaluating gap existing between materials and dentinal walls scanning electron microscopy. Given objectiv...

Seventy-five single-rooted teeth diagnosed with asymptomatic necrosis and apical periodontitis were randomly assigned to 3 experimental groups (n=25), according the root canal sealer: MTA Fillapex, CPM Sealer, AH Plus. Calcium hydroxide was employed as intracanal dressing throughout used during endodontic procedure. Classify each patient's discomfort none, slight, moderate, or severe. Pain rate...

Aim of the study is to compare quality apical seal offered by a zinc-eugenol and tricalcium-silicate-based sealer, both used with single-cone or continuous wave condensation technique. Forty central incisors were divided into four groups (n = 10), according two sealers obturation techniques under investigation, their outer surface was isolated nail varnish. After endodontic treatment, samples i...

OBJECTIVE Handling of endodontic sealers is greatly dependent on their elasticity and flow ability. We compared the viscoelastic properties of three root canal sealers. MATERIALS AND METHODS AH Plus (Dentsply, De Trey, Konstanz, Germany), Endofill (Dentsply Hero, Petrópolis, Rio de Janeiro, Brazil) and AH26 (Dentsply, De Trey, Konstanz, Germany) were mixed according to the manufacturers' inst...

OBJECTIVES Recently, bioceramic sealers like EndoSequence BC Sealer (BC Sealer) have been introduced and are being used in endodontic practice. However, this sealer has limited research related to its retreatability. Hence, the aim of this study was to evaluate the retreatability of two sealers, BC Sealer as compared with AH Plus using micro-computed tomographic (micro-CT) analysis. MATERIALS...
