Aim To assess the chemical and microstructural characteristics of dentine after use two irrigation protocols correlate this with antimicrobial properties hydraulic calcium silicate cement (HCSC) sealers changes to structure/chemistry sealer placement. Methodology Two – Protocol A using 2% NaOCl used 5 mL/5 min B (5 min) followed by 17% EDTA mL/3 were prepare dentine. The following assessed scan...

This study aimed to assess the influence of the type of endodontic sealer (salicylate resin-based sealer vs. two endodontic sealers) and the time of fiber post cementation after root filling on the post adhesion to bovine root dentin. Sixty bovine roots were assigned to six groups (n=10), considering an experimental design with two factors (factorial 3x2): endodontic sealer factor in three leve...

The aim of the present study was to evaluate the bond strength (BS) of root canal fillings to root dentin using the reciprocating file-matched single-cone or lateral compaction techniques with resin-based and calcium-silicate-based sealers. Maxillary canine roots were prepared and filled using one of the following approaches: Reciproc R40 file and R40 single cone, WaveOne Large file and Large s...

The aim of this study was to evaluate the influence of a calcium silicate-based sealer (iRoot SP), with or without a core material, on bond strength to radicular dentin, in comparison with various contemporary root filling systems. Root canals of freshly extracted single-rooted teeth (n = 60) were instrumented using rotary instruments. The roots were randomly assigned to one of the following ex...

Mineral trioxide aggregate (MTA) is a bioactive endodontic cement (BEC) mainly comprised of calcium and silicate elements. The cement was introduced by Torabinejad in the 1990s and has been approved by the Food and Drug Administration to be used in the United States in 1997. A number of new BECs have also been introduced to the market, including BioAggregate, Biodentine, BioRoot RCS, calcium-en...

The aim of this study was to evaluate the influence of drying protocols (DP) on the apical sealing (AS) and on the bond strength (BS) of teeth filled with different sealers. The root canals of one hundred and fifty-six roots of maxillary canines were prepared with Reciproc rotary files (R50). The teeth were randomly divided into four groups (n = 39), according to the DP: GI-paper points; GII-70...

Aim: The aim of the study was to compare the fracture resistance of endodontically treated teeth obturated with gutta percha using four different root canal sealers (MTA Fillapex, AH plus, Real Seal SE and Tubli Seal). Materials and methods: Sixty freshly extracted single rooted human mandibular premolar teeth were used. After standardizing the root length to 14 mm, the teeth were chemo mechani...
