The Release of Elements from Dental Casting Alloy into Cell-Culture Medium and Artificial Saliva

European Journal of Dentistry, 2007
Objectives The biocompatibility of dental casting alloys is a critical issue because these alloys are in long-term intimate contact with oral tissues. Since the biocompatibility of alloys is not completely known; the release of elements from the alloys ...

Surface Analysis of Keepers on Dental Magnetic Attachments : Comparison of Cast-Bonding Technique and Direct-Bonding Technique

Prosthodontic Research & Practice, 2004
Purpose : To obtain maximum attractive force for magnetic attachments, the degree of flatness of the keeper surface is very important. This study evaluated the flatness of keeper surfaces fabricated on copings using the cast-bonding and the direct-bonding techniques.Materials and Methods : Specimens were made with keepers from the Hyper Slim 3513 ...

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...
