Biocompatibility and biomineralization assessment of bioceramic-, epoxy-, and calcium hydroxide-based sealers
(Sociedade Brasileira de Pesquisa Odontológica - SBPqO, 2016-06-14)
Obturation of the root canal system aims to fill empty spaces, promoting hermetic sealing and preventing bacterial activity in periapical tissues. This should provide optimal conditions for repair, stimulating the process ...
Setting Time Affects In Vitro Biological Properties of Root Canal Sealers
(2013-09-30)
Introduction: Biocompatibility of root canal sealers is important because of the long-term contact of their eluates and/or degradation products with periapical tissues. The literature still lacks studies about the genotoxic ...

Rat tissue reaction and cytokine production induced by antimicrobial photodynamic therapy
(2017-06-01)
Background The antimicrobial photodynamic therapy (aPDT) inactivates the target cell via reactions among the photosensitizer (PS), Laser or Led and O2. The aim of this study was to evaluate the tissue reaction and cytokine ...
Cytotoxicity and genotoxicity of natural resin-based experimental endodontic sealers
(2016-05-01)
Objectives: The development of endodontic sealers based on natural resins seems to be promising, given their improved biological properties. This study evaluated the cytotoxic and genotoxic effects of two experimental root ...

(2009-01-01)
Objectives: To evaluate the effect of microwave postpolymerization heat treatment and water storage time on the cytotoxicity of denture base and reline acrylic resins. Method and Materials: Sample disks of 6 acrylic resins ...
Comparison of the biocompatibility of different root canal irrigants
(Universidade de São Paulo (USP), Faculdade de Odontologia de Bauru, 2013)
In vitro biocompatibility of a novel membrane of the composite poly(vinylidene-trifluoroethylene)/barium titanate
(Wiley-Blackwell, 2006-11-01)
This study was aimed at investigating the in vitro biocompatibility of a novel membrane of the composite poly(vinylidene-trifluoroethylene)/barium titanate (P(VDF-TrFE)/BT). Osteoblastic cells were obtained from human ...
