Hydroxyapatite Synthesis and Covering of Titanium Surfaces by Dip-Coating Method
Chisini,Luiz Alexandre; Paganotto,Gian Francesco dos Reis; Guergolette,Rodrigo; Conde,Marcus Cristian Muniz; Alcázar,Jose Carlos BernedoAbstract This study developed and characterized a method for controlled deposition of thin films of hydroxyapatite on titanium surfaces. Thirty-three titanium cylinders were randomly divided: negative control/polished (A), acid etched (B) and coated by hydroxyapatite (C). Acid etch was performed in an aqueous solution of nitric acid. The cylinders were subjected to coating by a thin film of hydroxyapatite with ...
Bone, Periodontal and Dental Pulp Regeneration in Dentistry: A Systematic Scopi...
Chisini,Luiz Alexandre; Conde,Marcus Cristian Muniz; Grazioli,Guillermo; Martin,Alissa Schmidt San; Carvalho,Rodrigo Varella deAbstract The aim of presented systematic scoping review was to investigate the actual and future clinical possibilities of regenerative therapies and their ability to regenerate bone, periodontal and pulp with histological confirmation of the nature of formed tissue. Electronic search was conducted using a combination between Keywords and MeSH terms in PubMed, Scopus, ISI-Web of Science and Cochrane library dat...
Venous Blood Derivatives as FBS-Substitutes for Mesenchymal Stem Cells: A Syste...
Chisini,Luiz A.; Conde,Marcus C.M.; Grazioli,Guillermo; Martin,Alissa S. San; Carvalho,Rodrigo Varella de; Nör,Jacques E.; Demarco,Flávio F.Abstract Although the biological properties of mesenchymal stem cells (MSC) are well-characterized in vitro, MSC clinical application is still far away to be achieved, mainly due to the need of xenogeneic substances for cell expansion, such as fetal bovine serum (FBS). FBS presents risks regarding pathogens transmissions and internalization of animal’s proteins, which can unleash antigenic responses in patients...
Does Cryopreservation Affect the Biological Properties of Stem Cells from Denta...
Conde,Marcus Cristian Muniz; Chisini,Luiz Alexandre; Grazioli,Guillermo; Francia,Alejandro; Carvalho,Rodrigo Varella de; Alcázar,Jose Carlos BernedoAbstract This systematic review evaluated if different cryopreservation protocols could affect biological properties (Cell survival rate (CSR), proliferation, differentiation, maintenance of stem cell markers) of stem cells obtained from dental tissues (DSC) post-thaw. An electronic search was carried out within PubMed and ISI Web Science by using specific keyword. Two independent reviewers read the titles and ...
Effects of Green Tea Application Time on Bond Strength after Enamel Bleaching
Ozelin,Andrezza Astafief; Guiraldo,Ricardo Danil; Carvalho,Rodrigo Varella de; Lopes,Murilo Baena; Berger,Sandrine BittencourtThis study evaluated the effect of green tea application time on the bond strength of enamel after enamel bleaching. Enamel samples were obtained from 80 third molars and randomly divided into 7 experimental groups (G1-G7) and 1 group without treatment (G8): G1, bleached with 10% carbamide peroxide (CP); G2, CP + 10% sodium ascorbate gel (SA) for 15 min; G3, CP + SA for 30 min; G4, CP + SA for 60 min; G5, CP + ...
Bond strength of HEMA-containing versus HEMA-free self-etch adhesive systems to...
Felizardo,Klíssia Romero; Lemos,Letícia Vargas Freire Martins; Carvalho,Rodrigo Varella de; Gonini Junior,Alcides; Lopes,Murilo Baena; Moura,Sandra KissThis study analyzed the bond strength (BS) of HEMA versus HEMA-free self-etch adhesive systems to dentin. The occlusal surface of 20 third molars was removed and the dentin was abraded with 600-grit silicon carbide paper. The teeth were randomly assigned to 4 groups (n=5) and restored with GO, Adper SE Plus, OptiBond All-In-One, and Clearfil 3S Bond adhesive systems and Filtek Z350 composite. After light curing...
Flexural strength and modulus of elasticity of different types of resin-based c...
Rodrigues Junior,Sinval Adalberto; Zanchi,Cesar Henrique; Carvalho,Rodrigo Varella de; Demarco,Flávio FernandoThe aim of the study was to test whether the filler composition of resin composites influences their flexural strength and modulus of elasticity. Flexural strength and modulus of elasticity were obtained through a three-point bending test. Twelve bar shaped specimens of 5 commercially available composites - Supreme (3M/ESPE), a universal nanofilled composite; Esthet-X (Dentsply), Z-250 (3M/ESPE), Charisma (Hera...
Shrinkage stress of three composites under different polymerization methods
Zanchi,Cesar Henrique; Carvalho,Rodrigo Varella de; Rodrigues Junior,Sinval Adalberto; Demarco,Flávio Fernando; Burnett Júnior,Luiz HenriqueThe aim of this study was to evaluate the shrinkage stress of three composites under different polymerization methods: halogen conventional polymerization (G1), halogen "soft-start" polymerization (G2) and LED polymerization (G3). The composites tested were Filtek Z-100 (3M/ESPE), Filtek Z-250 (3M/ESPE) and Solitaire 2 (Heraeus Kulzer). For G1, an XL-3000 (3M/ESPE) curing unit with light intensity of 507 mW/cm²...
