The Thermomechanical, Functional and Biocompatibility Properties of a Au-Pt-Ge Alloy for PFM Dental Restorations.

A high-noble Au-Pt-Ge porcelain-fused-to-metal (PFM) dental alloy without the known adverse metallic elements and with the addition of germanium (Ge) was produced as a more cost-effective alternative to other precious alloying metals, with investigations for determining the functionality and clinical use of this alloy. The thermomechanical, biocompatibility, durability, workability and economic characteristics of the produced dental alloy were investigated. These properties were investigated with in vitro biocompatibility testing on human gingival fibroblasts (HGFs); static immersion testing for metal ion release; DSC analysis; hardness, tensile testing, density and coefficient of thermal expansion (CTE) measurements; metallographic and SEM/EDX microstructure investigations; and finally with the production of a test PFM dental bridge.

Inflammatory mediators' essence in apical periodontitis.

Apical periodontitis (AP) represents chronic inflammatory reaction of periradicular tissues of teeth with necrotic pulp. Although AP has been considered as a multifactorial disease, different microorganisms and their virulence factors from infected root canals are considered to be the primary cause of periradicular inflammatory process. The interplay between microbes and host leads to an inflammatory cascade of events that includes activation of innate and adaptive components of immunity.

Endodontic treatment modifies circulatory inflammatory mediator levels: A systematic review with meta-analysis.

Background: There is limited and conflicting data on the reduction of circulatory inflammatory mediators in patients with apical periodontitis (AP) following endodontic treatment.

Objective: To answer the following research question: in adult healthy patients with AP [Population (P)], is there a difference before [Comparator (C)] and after various endodontic treatments (nonsurgical, surgical or retreatment) [Intervention (I)] on systemic levels of inflammatory biomarkers [Outcome (O)] in the follow-up period [Time (T)]?

Methods: An electronic literature search was conducted in the databases Scopus, PubMed, Clarivate Analytics' Web of Science, Cochrane Database of Systematic Reviews and Grey literature from inception to July 2024 with no language restrictions. Observational studies examining changes in serum levels of inflammatory mediators were included.
