In Vitro Microleakage of Class V Composite Restorations in Use of Three Adhesive Systems

Journal of Islamic Dental Association of Iran, 2016
Background and Aim: Microleakage is a drawback of composite restorations and it is more noticeable in dentinal walls. Despite advances in dentin bonding agents, no adhesive can completely eliminate microleakage and provide a hermetic seal.

Deep Margin Elevation With Various Resin Composites: Effect of Thermomechanical Aging on the Marginal Gap of CAD/CAM Inlays

Journal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective This in vitro study evaluated the effects of composite material type, margin design (deep margin elevation vs. control), and thermomechanical aging on the marginal gap of CAD/CAM inlay restorations. Materials and Methods Standardized mesio‐occluso‐distal (MOD) inlay cavities were prepared in extracted human molars, with mesial ...

Microleakage of "All-in-One" Adhesive Systems on Enamel and Dentinal Margins: An In Vitro Study

Frontiers in Dentistry, 2008
Objective: The use of presently available dentin bonding systems has greatly reduced mi-croleakage; however, the ideal situation where the adhesive resin completely penetrates the demineralized dentin is not yet achieved.

The effect of hemostatic agents and dentin cleansing protocols on shear bond strength of resin composite using universal adhesive: an in vitro study

BMC Oral Health
Background During restoring class II and V cavities with resin composite, hemostatic agents are frequently used to control gingival bleeding and/or gingival fluid to provide a dry field which is crucial for efficient bonding.

Bond strength and interfacial analysis of six CoCr alloys made by conventional casting and selective laser melting

Journal of Prosthodontics, EarlyView.
Abstract Purpose To investigate the effects of the elemental composition and the manufacturing process of cobalt chromium–molybdenum (CoCr–Mo), cobalt chromium–tungsten (CoCr–W), and CoCr–Mo‐W alloys on metal–ceramic bond strength. Materials and Methods Six CoCr‐based alloys were included in this study, a were classified into three different groups ...

Hydraulic fast‐setting calcium silicate cement for crown cementation

Journal of Prosthodontics, EarlyView.
Abstract Purpose This study evaluated film thickness, diametral tensile strength (DTS), and crown retentive strength of hydraulic fast‐set calcium silicate cement (fast‐set CSC) compared to conventional luting cements. Materials and Methods Fast‐set CSC was compared to zinc phosphate cement and glass ionomer cement.

Bone Grafts: Everything You Need to Know

Journal of Periodontal Research, EarlyView.
This review classifies bone grafts (autograft, allograft, xenograft, synthetic) by source and osteogenic/inductive/conductive potential, linking material properties and mechanisms to clinical indications in periodontal and dental regeneration. Key challenges—limited osteoinduction, poor vascularisation, unbalanced resorption, handling difficulties, and

Autogenous Demineralized Dentin Graft–Based Strategies With or Without I‐PRF and Metronidazole for Ridge Preservation in Infected Sockets: A Randomized Clinical Trial

Journal of Periodontal Research, EarlyView.
This randomized controlled trial evaluated the efficacy of demineralized dentin graft (DDG) combined with injectable platelet‐rich fibrin (I‐PRF) and metronidazole (MTZ) versus DDG with or without I‐PRF in alveolar ridge preservation (ARP) of infected extraction sockets.
