Comparison between tooth-derived matrix and DBBM granules on an enhanced bone h...
Cifreda, Victor; Fidalgo-Pereira, Rita; Henriques, Bruno; Teughels, Wim; Özcan, Mutlu; Souza, Júlio C. M.Purpose of the Review: The purpose of this study was to perform a scoping review on the comparison between tooth-derived matrix and demineralized bovine bone mineral (DBBM) granules for enhanced bone healing. Recent Findings: Previous studies reported micro-scale pores in dentin-matrix granules due to the remnant dentin that promote the adsorption of proteins and bioactive molecules. It should be highlighted th...
Short-pulse direct laser writing of 3Y-TZP zirconia: a superior surface modific...
Sahoo, Narayan; Carvalho, Óscar; Özcan, Mutlu; Eyüboğlu, Tan Fırat; Souza, Júlio C. M.; Silva, Filipe; Henriques, BrunoThe clinical success of zirconia-based restorations relies on surface modifications that enhance adhesion without compromising material integrity. This study evaluates Direct Laser Writing (DLW) as a non-contact, contamination-free alternative to conventional grit-blasting methods (alumina particle abrasion [SB] and silica-coated alumina treatment [SC]. Surface roughness (Ra), wettability, surface free energy (...
Realpolitik: A Political Reading of Alexander Zeldin’s The Inequalities Trilogy
Henriques, BrunoIn The Inequalities, Alexander Zeldin shows how injustice, the result of a violent process of capitalist exploitation, arrogantly governs the lives of those struggling to survive in England over the past decade: a dehumanizing dystopia carried out by the Conservative Party. Obliterated by labor, economic, social, political, and ontological precarity, the starving day laborers find, in Zeldin’s theatre, an oppor...
Laser-texturing and traditional surface modification to improve the adhesion of...
Fernandes, Valter; Carvalho, Oscar; Silva, Filipe; Henriques, Bruno; Özcan, Mutlu; Souza, Júlio C. M.Objectives The aim of this study was to perform experimental evaluation of the synergistic effects of laser-texturing and different traditional surface modification approaches to improve the push-out bond strength of glass fiber-reinforced composite (GFRC) posts to resin-matrix cements used in endodontically treated teeth rehabilitation. Methods One hundred and ten freshly extracted mandibular single-rooted pre...
Surface modification of glass fiber-reinforced composite posts by hydrogen pero...
Fernandes, Valter; Tuttle, Camilia; Carvalho, Óscar; Henriques, Bruno; Oliveira, Antonio Pedro Novaes de; Özcan, Mutlu; Souza, Júlio C. M.On the rehabilitation of endodontic treated teeth using intraradicular retention, adhesive failures often occur between the intraradicular post and the resin-matrix cement. The main aim of this study was to conduct a scoping review on the surface modification of glass fiber-reinforced composite posts by hydrogen peroxide solutions. An electronic search was performed in the PubMed database, using combi...
The impact of inorganic fillers, organic content, and polymerization mode on th...
Santos, Marcionilia; Fidalgo-Pereira, Rita; Torres, Orlanda; Carvalho, Oscar; Henriques, Bruno; Özcan, Mutlu; Souza, Júlio C. M.PURPOSE: The main aim of the present study was to carry out a scoping review on the differences in degree of conversion of monomers regarding several types resin cements, indirect restorative materials, and light-curing procedures used in dentistry. METHOD: A bibliographic review was performed on PubMed using the following search items: "degree of conversion" OR "filler" AND "resin cement" OR "inorganic cement"...

Multi-scale laser micropatterning of dental zirconia(3Y-TZP) for enhanced adhes...
Sahoo, Narayan; Carvalho, Oscar; Özcan, Mutlu; Silva, Filipe; Lasagni, Andrés-Fabian; Henriques, BrunoZirconia (3Y-TZP) is a highly valued material in dentistry due to its exceptional mechanical strength, biocompatibility, and aesthetic appeal, making it ideal for crowns, bridges, and implants. However, achieving strong adhesion to zirconia is challenging because of its chemical inertness and low surface energy, which prevent effective bonding with traditional dental cements[1-3]. This study evaluated the impac...
