Effect of diode laser on micro-tensile bond strength of hybrid ceramic restorations to dentin using one-step and two-step self-etch adhesives: in vitro study

Abstract Background This study aimed to evaluate the effect of diode laser irradiation on the micro-tensile bond strength (µTBS) of hybrid ceramic restorations bonded to dentin using one-step and two-step self-etch adhesives. Methods An in vitro study was conducted using 20 fresh...

Microbial and Enzymatic Transformation of Per- and Polyfluoroalkyl Substances (PFAS): From Defluorination and Biological Partitioning to a Separation-First Biological Treatment Framework

Per- and polyfluoroalkyl substances (PFAS) are persistent environmental pollutants. Conventional destructive technologies, such as advanced oxidation and electrochemical processes, can achieve partial or complete defluorination. However, their high energy demand, chemical inputs,...
