BACKGROUND Chairside softliners are used more frequently than is reported and studies regarding the bond strength of chairside softliners to heat-polymerized denture base resin are few and limited. Hence, this study was conducted to comparatively evaluate the shear bond strength of two chairside soft relining materials viz., autopolymerizing plasticized acrylic resin liner and a silicone-based ...

STATEMENT OF PROBLEM Computer-aided design and computer-aided manufacturing (CAD/CAM) resins exhibit good mechanical properties and can be used as long-term restorations. The wear rate of such resins and their enamel antagonists is unknown. PURPOSE The purpose of this study was to test and compare the 2-body wear rate of CAD/CAM resin blocks. MATERIAL AND METHODS Wear specimens (N=42, n=6) ...

UNLABELLED Since Matrix metalloproteinases (MMPs) have been suggested to contribute to dentin caries progression, the hypothesis that MMP inhibition would affect the progression of dentin caries is clinically relevant. Grape seed extracts (GSE) have been previously reported to be natural inhibitors of MMPs. OBJECTIVE To evaluate the capacity of a GSE mouthrinse to prevent the degradation of d...

OBJECTIVE Many commercial dental materials are used to fabricate interim restorations. This study aimed to compare the color stability and the marginal integrity of four different interim crown materials. MATERIALS AND METHODS An ivorine right maxillary central incisor was prepared for a full coverage all-ceramic restoration. A total of 36 specimens in the form of crowns were fabricated on th...

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-...

STATEMENT OF PROBLEM Shear bond strength (SBS) of home and office bleached enamel will be compromised by immediate application of composite restoration. Antioxidant agent may overcome this problem. OBJECTIVES This in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. MATERIALS AND METHODS In this experimental...

Objective: The aim was to evaluate the influence of fluoride-releasing restorative materials in enamel and dentinmicrohardness. Material Methods: 40 blocks (5x5x3 mm) from cervical third human molars received a cavitypreparation between dentin, restorations were subjected vitro caries model. Specimenswere randomly restored with (n=10): conventional glass ionomer cement (Ketac Cem, 3M ESPE); pol...

STATEMENT OF THE PROBLEM The adhesion of resin-modified glass-ionomer (RMGI) to composite resin has a very important role in the durability of sandwich restorations. Hydroxyapatite is an excellent candidate as a filler material for improving the mechanical properties of glass ionomer cement. PURPOSE The aim of this study was to assess the effect of adding micro- and nano-hydroxyapatite (HA) p...

This paper presents a game intended to train teams that have both individual and teams goals to negotiate collaboratively in order to reach the team goal in the best way possible. We consider self-managing teams, i.e., teams that do not have a hierarchical structure. The importance of the team goal in comparison to their individual goals is touched upon, as are various conflicts that can occur ...
