Purpose: To evaluate the chemical and physical properties of a tricalcium silicate root canal sealer containing povidone and polycarboxylate (BioRoot RCS), a calcium silicate MTA-based sealer containing a salicylate resin (MTA Fillapex), a traditional eugenol- containing sealer (Pulp Canal Sealer) and an epoxy resin-based root canal sealer (AH Plus).
Materials and methods:
•The study was mainly to evaluate the following chemical and physical properties:
•1) pH and calcium release: the number of calcium ions release after mixing was measured using a calcium probe.
•2) Setting times: the initial and final setting times were measured.
•3) Radiopacity: The radiopacity tests were preformed in accordance with ISO.
•4) Solubility, water sorption, porosity: after preparing the pastes, the samples were weighted and water sorption and solubility were measured and were measured again after 7 days
•The materials were prepared according to the manufacturers instructions and tested immediately
Most highlighted results:
•BioRoot RCS: Final setting time of 300 mins, adequate radiopacity, the highest release of calcium ions, and the highest porosity, water sorption and solubility.
•MTA Fillapex: Final setting time of 270 mins, apatite deposits were present on aged samples.
•AH plus and pulp canal sealer: had 1240 mins and 60 mins final setting times respectively, no calcium and no alkalizing activity were measured for both materials.
Clinical significance: The data support the potential of BioRoot RCS to promote periapical healing, bone regeneration and sealing by mineralization and apatite deposition at the root canal wall interface.
