A novel tooth bleaching gel based on peroxymonosulfate/polyphosphates advanced oxidation process: Effective whitening avoiding pulp damage and sensitivity

Pulp damage and bleaching sensitivity caused by existing hydrogen peroxide (HP) bleaching gel is a major challenge that needs to be solved urgently in the field of vital bleaching, mainly due to HP’s intrinsic high penetrability and strong oxidative property. The present study has successfully developed a novel non-hydrogen peroxide bleaching system based on peroxymonosulfate (PMS)/polyphosphates advanced oxidation process, with suitable...
