Journal ArticleDOI
Effect of surface conditioning methods on the microtensile bond strength of resin composite to composite after aging conditions.
Mutlu Özcan,Silvia Helena Barbosa,Renata Marques de Melo,Graziela Galhano,Marco Antonio Bottino +4 more
TL;DR: Chairside silica coating and silanization provided higher resin-resin bond strength values compared to acid etching with phosphoric acid followed by adhesive resin applications and Citric acid was the least aggressive aging medium.
Journal ArticleDOI
Effect of different finishing and polishing techniques on the surface roughness of microfilled, hybrid and packable composite resins
TL;DR: The smoothest surfaces were obtained with the use the complete sequence of Sof-Lex discs, and in areas that could not be reached by the aluminum oxide discs, the carbide burs and the association between rubber points and polishing pastes produced satisfactory surface smoothness for the packable and hybrid composite resins, respectively.
Journal ArticleDOI
Effect of caries preventive measures directed to expectant mothers on caries experience in their children
Régia Luzia Zanata,Maria Fidela de Lima Navarro,José Carlos Pereira,Eduardo Batista Franco,José Roberto Pereira Lauris,Silvia Helena Barbosa +5 more
TL;DR: Evidence is supported of an association between caries prevalence in young children and clinical (dental plaque) and maternal factors and Maternal caries increase was a significant factor influencing the caries experience of the children.
Journal ArticleDOI
Repair bond strength of microhybrid, nanohybrid and nanofilled resin composites: effect of substrate resin type, surface conditioning and ageing.
Mutlu Özcan,Pedro Henrique Corazza,Susana María Salazar Marocho,Silvia Helena Barbosa,Marco Antonio Bottino +4 more
TL;DR: On the aged RBCs, less favourable repair strength could be expected especially for nanohybrid composite, but less number of pre-test failures was experienced with the CoJet system compared to adhesive resin application only.
Journal Article
Does the thickness of the resin cement affect the bond strength of a fiber post to the root dentin
Bianca E M Perez,Silvia Helena Barbosa,Renata Marques de Melo,Sandra Costa Zamboni,Mutlu Özcan,Luiz Felipe Valandro,Marco Antonio Bottino +6 more
TL;DR: This study aimed to evaluate the influence of cement thickness on the bond strength of a fiber-reinforced composite (FRC) post system to the root dentin using single-rooted human teeth decoronated with adhesive plus resin cement.
