Effect of dental bleaching after bracket bonding and debonding using three diff...
Gomes,Lucianna de Oliveira; Mathias,Paula; Rizzo,Patricia; Araújo,Telma Martins de; Cangussu,Maria Cristina TeixeiraOBJECTIVE: To evaluate the influence of bonding and debonding of orthodontic brackets on dental in-home bleaching, taking into account three different adhesive systems. METHODS: Forty-four bovine incisors were divided into four groups according to the primer system used for orthodontic bracket bonding. Following the debonding of orthodontic brackets, the teeth were stored in staining solution for 96 hours. Then...
Effect of a desensitizing dentifrice on the bond strength of different adhesive...
Cavalcanti,Andrea Nóbrega; Souza,Evangelista Santos de; Lopes,Gabriela dos Santos; Freitas,Anderson Pinheiro de; Araújo,Roberto Paulo Correia deAIM: This in vitro study evaluated the effect of using a dental hypersensitivity treatment on the bond strength to dentin of etch-and-rinse and self-etching simplified adhesive systems. METHODS: 40 healthy molars were used. The crowns of teeth were removed at the dentinoenamel junction, and remaining roots were sectioned in the mesiodistal direction along their long axis, separating the buccal and lingual/palat...
Effect of lipstick on composite resin color at different application times
Galvão,Avilmar Passos; Jacques,Letícia Borges; Dantas,Luciana; Mathias,Paula; Mallmann,AndréOBJECTIVES: The aim of this study was to evaluate the influence of the contact of two lipsticks, one with common fixer and one with ultra fixer, on the color of a composite resin immediately, 30 min and 24 h after photoactivation. MATERIAL AND METHODS: Ninety specimens were prepared with a composite resin, Filtek-Z350. Specimens were polished and divided into 9 groups (n=10) according to time elapsed after phot...
Microleakage at the composite-repair interface: effect of different adhesive sy...
Cavalcanti,Andrea Nóbrega; Lavigne,Catarina; Fontes,Céres Mendonça; Mathias,PaulaThe purpose of the present study was to evaluate the microleakage at the composite-repair interface using different bonding systems. Composite resin specimens (Filtek Z250 - 3M-ESPE) were divided into five groups (n=20) according to the following bonding mechanism: C - control - etching with 35% phosphoric acid; SB1 - etching and application of one coat of Single Bond (3M-ESPE); SB2 - etching and application of...
