Influence of adhesive system and bevel preparation on fracture strength of teeth restored with composite resin
Brazilian Dental Journal - Tập 21 Số 4 - Trang 327-331 - 2010
Fábio Herrmann Coelho-de-Souza, Analice da Cunha Rocha, Alessandro Rubini, Celso Afonso Klein-Júnior, Flávio Fernando Demarco
The aim of this study was to evaluate the fracture strength of teeth with different cavosurface margin cavity preparations and restored with composite resin and different adhesive systems. Eighty premolars were randomly divided in 8 groups, as follow: G1- sound teeth; G2- MOD preparation (no restoration); G3- Adper Single Bond without bevel preparation (butt joint); G4- Adper Single Bond w...... hiện toàn bộ
Effect of hydrofluoric acid etching duration on the roughness and flexural strength of a lithium disilicate-based glass ceramic
Brazilian Dental Journal - Tập 22 Số 1 - Trang 45-50 - 2011
Lucas Villaça Zogheib, Álvaro Della Bona, Estevão Tomomitsu Kimpara, J.F. McCabe
The aim of this study was to examine the effect of different acid etching times on the surface roughness and flexural strength of a lithium disilicate-based glass ceramic. Ceramic bar-shaped specimens (16 mm x 2 mm x 2 mm) were produced from ceramic blocks. All specimens were polished and sonically cleaned in distilled water. Specimens were randomly divided into 5 groups (n=15). Group A (c...... hiện toàn bộ
Osteoporosis Affects Functional Activity and Gene Expression of Osteoblastic Cells Derived from Rat Alveolar Bone
Brazilian Dental Journal - Tập 31 Số 6 - Trang 617-622
Paula Katherine Vargas Sánchez, Roger Rodrigo Fernandes, Flávia Aparecida Chaves Furlaneto, Luiz Gustavo de Sousa, Selma Siéssere, Karina Fittipaldi Bombonato‐Prado
Abstract Recent studies suggest that osteoporosis, in addition to the damage caused in long bones, may cause deterioration in the jaws, especially in alveolar bone sites, with effects in the progress of periodontal disease as well as in bone healing. The aim of this study was to evaluate the effect of osteoporosis in the metabolism of rat alveolar bone osteoblasts. There were used 10 femal...... hiện toàn bộ
Acid Etching and Surface Coating of Glass-Fiber Posts: Bond Strength and Interface Analysis
Brazilian Dental Journal - Tập 27 Số 2 - Trang 228-233 - 2016
Doglas Cecchin, Ana Paula Farina, Rafael Pino Vitti, Rafael R. Moraes, Ataís Bacchi, Aloísio Oro Spazzin
Abstract The aim of this study was to evaluate the bond strength of a composite resin to glass-fiber post (GFP) treated or not with phosphoric acid, silane coupling agent, and unfilled resin. GFPs were etched or not with 37% phosphoric acid and different surface coating applied: silane coupling agent, unfilled resin, or both. Composite resin blocks were built around a 4-mm height on the GF...... hiện toàn bộ
Behavioral problems and emotional stress in children with bruxism
Brazilian Dental Journal - Tập 23 Số 3 - Trang 246-251 - 2012
Adriana do Vale Ferreira-Bacci, Cármen Lúcia Cardoso, Kranya Victória Díaz‐Serrano
Bruxism has a multifactorial etiology, and psychosocial factors have been considered to increase the risk of occurrence of this parafunction. The aim of this study was to evaluate the behavior profile of a group of children diagnosed with bruxism. Eighty 7-11-year-old children of both genders (mean age 8.8 years) first recruited as eligible participants. Twenty-nine children (18 males and ...... hiện toàn bộ
Effect of Chlorhexidine on Dentin Bond Strength of Two Adhesive Systems after Storage in Different Media
Brazilian Dental Journal - Tập 26 Số 6 - Trang 642-647 - 2015
Enio Marcos da Silva, Daniel Hatschbach Glir, Allana Walesca Martins Castanho Gill, Allan Fernando Giovanini, Adilson Yoshio Furuse, Carla Castiglia Gonzaga
The aim of this study was to evaluate the effect of 2% chlorhexidine (CHX) application during the bonding protocol on microshear bond strength of two adhesive systems, after storage in different media. Seventy-two human molars had their crowns cut in half and embedded in PVC cylinders with acrylic resin. The specimens were randomly divided into experimental groups (n=12) according to the a...... hiện toàn bộ
Research Reporting Guidelines in Dentistry: A Survey of Editors
Brazilian Dental Journal - Tập 28 Số 1 - Trang 3-8
Rafael Sarkis‐Onofre, Maximiliano Sérgio Cenci, David Moher, Tatiana Pereira‐Cenci
Abstract The use of reporting guidelines has an important role in the development of health research, improving the quality and precision of the publications. This study evaluated how dental journals use reporting guidelines. All editors of dental journals registered on the 2013 Journal Citation Reports list (n=81) were invited to participate. The data were collected by a self-reported web...... hiện toàn bộ
