Long‐term clinical outcomes of periodontal regeneration of intrabony defects: A systematic review and meta‐analysis

Periodontology 2000, EarlyView.
Abstract This systematic review and meta‐analysis aimed to evaluate the long‐term clinical outcomes of regenerative procedures compared with access flap surgery for the treatment of intrabony defects, with a minimum follow‐up period of 5 years. A systematic review protocol following PRISMA guidelines was conducted.

Molecular Passivation with 2‐Aminobenzothiazole Enables Efficient and Stable Ruddlesden–Popper Tin Perovskite Solar Cells

Solar RRL, Volume 10, Issue 11, 15 June 2026.
Using 2‐aminobenzothiazole additive in quasi‐two‐dimensional tin perovskite improved energy‐level alignment of the perovskite layer to match that of other charge transport layers leading to an improved solar cell performance. The additive also inhibitted iodine ion migration and oxidating leading to better solar cell stability.
