“…Even exposure of Ni-Cr alloys to E. coli LPS, in an acidic environment (pH <5) decreases their corrosion resistance. Therefore, corrosion resistance is a fundamental characteristic of dental alloys to show better biocompatibility with tooth supporting tissues 54) .…”

Prosthetic biomaterials can affect the composition of the subgingival microbiota and consequently the production of proinflammatory cytokines, causing damage to the periodontium. A total of 40 patients were divided into two groups: 20 with monolithic zirconia (MZ) prostheses and 20 with porcelain fused to metal (PFM) with nickel-chromium (Ni-Cr) alloy prostheses. Subgingival plaque and gingival crevicular fluid samples were taken. The Checkerboard technique for DNA-DNA hybridization and the enzyme-linked immunosorbent assay technique were performed. Teeth with MZ presented a lower percentage of bleeding on probing and tooth mobility compared to teeth with PFM with Ni-Cr alloy. Prosthodontic teeth harbored higher total levels of the 18 bacterial species than non-prosthodontic teeth. There was a higher prevalence of S. gordonii and V. parvula species in PFM with Ni-Cr alloy compared to MZ. There was an increase in IL-1β, TNF-α and CX3CL1 levels in PFM with Ni-Cr alloy compared to MZ. MZ is a candidate biomaterial with fewer negative effects on the periodontium, allowing for longer prostheses longevity in the mouth.

A facultatively anaerobic, mesophilic, chemoorganoheterotrophic bacterium, designated YP2 T , was isolated from oil sludge enrichment in China. Cells of the strain were Gram-stain-negative, non-motile, rod-shaped or slightly curved with 0.8-3.0 µm in length and 0.4-0.6 µm in diameter. Spore formation was not observed. The strain YP2 T grew optimally at 25 o C (range from 15 to 30 o C) and pH 7.1 (range from pH 7.1 to 8.3) without NaCl. The major cellular fatty acids were C 16:0 , sum in feature 3 (C 16:1 ω7c and/or C 16:1 ω6c), sum in feature 8 (C 18:1 ω7c and/or C 18:1 ω6c), and the main polar lipids were aminolipid, phosphatidylethanolamine, phosphatidylglycerol, phospholipid and unidenti ed lipids. The respiratory quinone was Q-10. The DNA G + C content was 66.0%. Strain YP2 T shared 90.2% 16S rRNA gene sequence similarity with the most related Oceanibaculum nanhaiense L54-1-50 T belonging to the order Rhodospirillales of the class Alphaproteobacteria. Phylogenetic analyses based on 16S rRNA gene sequences showed that strain YP2 T formed a distinct evolutionary lineage within the order Rhodospirillales. On the basis of phenotypic, phylogenetic and phylogenomic data, we propose that strain YP2 T represents a novel species in a novel genus, for which Shumkonia mesophila gen. nov., sp. nov., within a new family Shumkoniaceae fam. nov.. The type strain is YP2 T (= CCAM 826 T = JCM 34766 T ).
