Geostandards and Geoanalytical Research, EarlyView.Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Transillumination‐Aided Infiltration of MIH‐Affected Molars: Evaluation of the Clinical Workflow
International Journal of Paediatric Dentistry, EarlyView.ABSTRACT Background Enamel affected by molar incisor hypomineralisation (MIH) exhibits reduced mechanical properties due to its disorganised prismatic structure, lower mineral density and higher protein content. These alterations increase porosity and susceptibility to posteruptive enamel breakdown.
