On the evaluation of a public transportation network quality : criteria validat...
Guedes, M. C. M.; Oliveira, Natália; Santiago, Sérgio; Smirnov, GeorgiA public transportation network serves in adequate way a population if it evolves in time following the existent social reality. Changes made in order to improve service must be analyzed and evaluated. The introduction of modern technology to validate the fare card allowed a quick access to important, although incomplete, data. A data basis with the validation information can be used to construct an origin-dest...
Dentin hypersensitivity after treatment with desensitizing agents: a randomized...
Assis,Jorgiana Silva de; Rodrigues,Lidiany Karla Azevedo; Fonteles,Cristiane Sá Roriz; Colares,Regina Cláudia Ramos; Souza,André Mattos Brito deThe aim of this study was to evaluate the efficacy of two desensitizing agents in the reduction of dentin hypersensitivity in a randomized, double-blind, split-mouth clinical trial. Seventy-seven teeth from 13 patients that presented some degree of sensitivity to probing and/or air stimulation were treated with one of the following desensitizing agents: Oxa-Gel (G1), Sensi Kill (G2) and placebo gel (G3 - contro...
Two-year clinical evaluation of resinous restorative systems in non-carious cer...
Santiago,Sérgio Lima; Passos,Vanara Florêncio; Vieira,Alessandra Helen Magacho; Navarro,Maria Fidela de Lima; Lauris,José Roberto PereiraThis controlled clinical trial evaluated the 2-year clinical performance of a one-bottle etch-and-rinse adhesive and resin composite system (Excite/Tetric Ceram) compared to a resin-modified glass ionomer cement (RMGIC) (Vitremer/3M) in non-carious cervical lesions. Seventy cervical restorations (35 resin composite - RC- restorations and 35 RMGIC restorations) were placed by a single operator in 30 patients und...
Effect of commercially available and experimental potassium oxalate-based denti...
Santiago,Sérgio Lima; Pereira,José Carlos; Martineli,Ana Christina Bonato FigueiredoThis study evaluated the influence of time after application of oxalate solutions in reducing dentin hydraulic conductance. Fifty dentin discs were obtained from extracted human third molars and assigned to 5 groups (n=10), according to the desensitizing agent used: Group I: OxaGel; Group II: experimental agent DD-1: Group III: experimental agent DD-2. In Groups IV and V, a placebo gel and deionized water were ...
Esclerose de pequenos vasos venosos com corrente elétrica galvânica ponteada, e...
Santiago,Sergio; Taha,Murched Omar; Fagundes,Djalma JoséFoi idealizado e construido um aparelho que utiliza a corrente elétrica galvânica em baixa amperagem (100m A ,200m A, 300m A) com o propósito de causar esclerose em vasos venosos de pequeno calibre, utilizando a veia marginal da orelha direita do coelho. O presente estudo buscou verificar em modelo experimental, o efeito da corrente elétrica galvânica em baixa amperagem. Foram utilizados 45 coelhos Nova Zelandi...
