The scandal that keeps on giving: FBI claims it “LOST” months of text messages belonging to disgraced anti-Trump agent Peter Strzok
(Natural News) When the complete (and unbiased) history is written on President Barack Obama’s administration, future generations of Americans will come to learn that his was the most corrupt in the country’s history. Forget Teapot Dome. Forget Watergate. Forget Bill Clinton’s sexual proclivities. Barack Obama has them all beaten, and by a wide margin. Because,...

This study further shows that porous TiTa scaffolds fabricated using L-PBF are biocompatible with comparable biological results and manufacturability as Ti6Al4V and commercially pure titanium, based on the results obtained from cell culture with human osteosarcoma cell line SAOS-2.

CONCLUSION: Within the constraints of the test method in this experiment, zirconia irrespective of surface preparation, was found to cause less vertical and volumetric enamel wear compared to control enamel. No statistically significant difference was seen between LP zirconia and LP + CA zirconia. PMID: 32469712 [PubMed - as supplied by publisher]
We examined the distribution of hardness and modulus across the lingual-buccal enamel cross-section by nanoindentation. At the occlusal surface, the hardness and modulus of enamel were found to be 5.00 ± 0.22 GPa and 97.12 ± 2.95 GPa, respectively. At the area close to the enamel-dentine-junction (EDJ), the hardness and modulus were 3.72 ± 0.35 GPa and 76.83 ± 5.71 GPa, respectively. At the middle region in between the EDJ and the outer enamel layer, the hardness and modulus were found to be 4.23 ± 0.18 GPa and 87....
