BACKGROUND The cementation of fixed implant-supported dental restorations involves the risk of leaving excess cement in the mouth which can promote biofilm formation in the peri-implant sulcus. As a result, an inflammation may develop. PURPOSE The aim of the present study was to investigate the clinical effect of two different luting cements on the peri-implant tissue. MATERIALS AND METHODS...

A three-dimensional (3D) dentin/pulp tissue analogue, resembling the human natural has been engineered in an vitro setup, aiming to assess cytocompatibility of resin-based dental restorative cements. Stem Cells from Apical Papilla (SCAP) and Human Umbilical Vein Endothelial (HUVEC) were embedded Collagen-I/Fibrin hydrogels at 1:3 ratio within 24-well plates. Hanging culture inserts placed over ...

Purpose: The effect of accelerated aging on color stability of various dual-cured self-adhesive resin cements were evaluated in this study. Materials and Methods: Color stability was examined using three different brands of dual-cured self-adhesive resin cements: G-CEM LinkAce (GC America), MaxCem Elite (Kerr), and PermaCem 2.0 (DMG) with the equivalent color shade. Each resin cement was filled...

OBJECTIVE To evaluate the bond stability of resin cements when luted to glass-reinforced alumina and zirconia CAD/CAM dental ceramics. STUDY DESIGN Eighteen glass-infiltrated alumina and eighteen densely sintered zirconia blocks were randomly conditioned as follows: Group 1: No treatment; Group 2: Sandblasting (125 µm Al₂O₃-particles); and Group 3: Silica-coating (50 µm silica-modified Al₂O₃-...

Zirconia (ZrO(2)) and barium sulfate (BaSO(4)) particles were introduced into a methyl methacrylate monomer (MMA) solution with polymethyl methacrylate (PMMA) beads during polymerization to develop the following novel bone cements: bone cements with unfunctionalized ZrO(2) micron particles, bone cements with unfunctionalized ZrO(2) nanoparticles, bone cements with ZrO(2) nanoparticles functiona...

Fixed restorations are now among the most common in modern dental prosthodontics. The current view prosthodontics of maximum preparation economy is causing an increased interest mechanical properties cements. Among important materials used for indirect cementation properties, i.e., hardness and compressive strength. These can change as a result changes physical factors. purpose this study was t...

OBJECTIVE A systematic review was conducted to analyze Brazilian scientific and technological production related to the dental materials field over the past 50 years. MATERIAL AND METHODS This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (Prisma) statement. Searches were performed until December 2014 in six databases: MedLine (PubMed), Scopus, LILACS, ...
