Universal adhesives and dual-cured core buildup composite material: adhesive pr...
Malaquias,Pâmela; Gutiérrez,Mario Felipe; Sutil,Elisama; Matos,Thalita de Paris; Hanzen,Taise Alessandra; Reis,Alessandra; Perdigão,JorgeAbstract Dual-cured buildup composites and simplified light-cured adhesive systems are mixed with a chemical activator to prevent the incompatibility between them. Objective: To evaluate microshear bond strength (μSBS) and nanoleakage (NL) of three universal adhesives used under buildup composites using different curing modes, at baseline and after 6-months (6m). Methodology: Dentin specimens of 55 molars were ...
Does the Use of Reservoirs Have Any Impact on the Efficacy of At-Home Bleaching...
Martini,Eveline Claudia; Parreiras,Sibelli Olivieri; Acuña,Eric Dario; Loguercio,Alessandro Dourado; Reis,AlessandraAbstract To answer the following focused question through a systematic review: “Are the risk and intensity of tooth sensitivity (TS) and bleaching efficacy different between adult patients who undergo at-home bleaching using trays with reservoirs and those who use trays without reservoirs?”. A comprehensive search was performed in the MEDLINE via PubMed, Scopus, Web of Science, Latin American and Caribbean Heal...
Preemptive Use of Piroxicam on Tooth Sensitivity Caused By In-Office Bleaching:...
Peixoto,Aline de Carvalho; Vaez,Savil Costa; Soares,Karla DaniellyAlves; Ferreira,Lorena Fernandes; Loguercio,Alessandro DouradoAbstract This clinical trial evaluated the effect of preemptive use of the non-steroidal anti-inflammatory drug piroxicam in a single dose 30 min prior to in-office bleaching on the prevention of tooth sensitivity (TS) reported by patients. Fifty patients were submitted to two sessions of in-office tooth bleaching with 35% hydrogen peroxide used for 2 sessions, each consisting of a single 45-min application, wi...
Evaluation of degree of conversion, microtensile bond strength and mechanical p...
Freitas,Samantha Ariadne Alves de; Lanza,Marco Daniel Septimo; Carneiro,Karina Kato; Loguercio,Alessandro Dourado; Bauer,JoséAbstract This study evaluated microtensile bond strength (µTBS), degree of conversion, modulus of elasticity and ultramicrohardness of three etch-and-rinse adhesives systems. The materials evaluated were: Ambar (FGM), Optibond (Kerr) and Magic Bond (Vigodent). The degree of conversion was analyzed by FTIR/ATR. To evaluate bond strength (μTBS) in dentin, 15 teeth (n = 5) were restored and sliced to obtain the sp...
Effect of Storage Time on Microtensile Bond Strength of Self-Adhesive and Multi...
Carvalho,Edilausson Moreno; Souza,William Lillicker Padilha de; Carvalho,Ceci Nunes; Maciel,Adeilton Pereira; Loguercio,Alessandro Dourado; Bauer,JoséThe purpose of this study was to evaluate the effects of long-term storage on the microtensile bond strength (µTBS) to dentin of two self-adhesive and three multi-step resin cements. Two self-adhesive cements RelyX U100 (U100) and seT PP (SET), and 3 multi-step resin cements, one using 2-step etch-and-rinse adhesive AllCem (ALC), and two conventional resin cements with self-etching primer Panavia F (PAN) and Mu...
Properties of Composite Materials Used for Bracket Bonding
Gama,Ana Caroline Silva; Moraes,Andre Guaraci de Vito; Yamasaki,Lilyan Cardoso; Loguercio,Alessandro Dourado; Carvalho,Ceci Nunes; Bauer,JoseThe purpose of this study was to evaluate in vitro the shear bond strength to enamel, flexural strength, flexural modulus, and contraction stress of one orthodontic composite and two flowable composites. Orthodontic brackets were bonded to 45 human maxillary premolars with the composites Transbond XT, Filtek Z-350 flow and Opallis flow and tested for shear bond strength. For measurement of flexural strength and...
Effects of zirconia nanoparticles addition to experimental adhesives on radiopa...
Martins,Gislaine Cristine; Meier,Marcia Margarete; Loguercio,Alessandro Dourado; Cecchin,Fabielle; Gomes,Osnara Maria Mongruel; Reis,AlessandraAIM: To evaluate the radiopacity and microhardness (KHN) of experimental dental adhesives (EX). The experimental adhesive resins of the present study were formulated based on the simplified adhesive system Ambar (FGM). METHODS: Five EX with different concentrations of zirconia nanoparticles [0(EX0), 15(EX15), 25(EX25), 30(EX30) e 50%(EX50)] were incorporated in a UDMA/HEMA adhesive (control). Adper Single BondT...
Effect of the application time of phosphoric acid and self-etch adhesive system...
Mena-Serrano,Alexandra Patricia; Garcia,Eugenio Jose; Perez,Miguel Munoz; Martins,Gislaine Cristine; Grande,Rosa Helena MirandaObjective: To evaluate the effect of application time on the resin-dentin bond strength (µTBS) and etching pattern of adhesive systems applied on sclerotic dentine. Material and Methods: A total of forty-two bovine incisors had their roots removed. The 1-step self-etch GO (SDI), the 2-step self-etch Adper SE Bond (3MESPE) and the 35% phosphoric acid (3MESPE) from the 2-step etch-and-rinse Adper Single Bond 2 (3...
Influence of alloy microstructure on the microshear bond strength of basic allo...
Bauer,José; Costa,José Ferreira; Carvalho,Ceci Nunes; Souza,Douglas Nesadal de; Loguercio,Alessandro Dourado; Grande,Rosa Helena MirandaThe aim of this study was to evaluate the influence of microstructure and composition of basic alloys on their microshear bond strength (µSBS) to resin luting cement. The alloys used were: Supreme Cast-V (SC), Tilite Star (TS), Wiron 99 (W9), VeraBond II (VBII), VeraBond (VB), Remanium (RM) and IPS d.SIGN 30 (IPS). Five wax patterns (13mm in diameter and 4mm height) were invested, and cast in a centrifugal cast...

Lenzi,Tathiane Larissa; Tedesco,Tamara Kerber; Soares,Fabio Zovico Maxnuck; Loguercio,Alessandro Dourado; Rocha,Rachel de OliveiraThe aim of this study was to evaluate the effect of 2% chlorhexidine digluconate (CHX) on immediate bond strength of etch-and-rinse adhesive to sound (SD) and caries-affected (CAD) primary dentin compared with permanent dentin. Flat dentin surfaces from 20 primary molars (Pri) and 20 permanent molars (Perm) were assigned to 8 experimental groups (n=5) according to tooth type (Pri or Perm), dentin condition (SD ...
