AIM Tetracycline-stained tooth structure is difficult to bleach using nightguard tray methods. The possible benefits of in-office light-accelerated bleaching systems based on the photo-Fenton reaction are of interest as possible adjunctive treatments. This study was a proof of concept for possible benefits of this approach, using dentine slabs from human tooth roots stained in a reproducible ma...

This work focuses, for the first time, on mechanistic modelling of wastewater disinfection by solar photo-Fenton process using controlled simulated radiation. At circumneutral pH, iron precipitates forming hydroxides and significantly affecting optical properties water. In this regard, radiation transfer in reactor has been taken into account. The proposed model considers that inactivation bact...
