Analysis of the effects of several decalcifying agents alone and in combination with sodium hypochlorite on the chemical composition of dentine

Abstract

HEDP and EDTANa₄ caused minor whilst EDTAHNa₃ and PAA caused greater demineralization of dentine; both effects were time and concentration dependent. NaOCl degraded the dentine organic matrix more rapidly when it was exposed. Combinations of NaOCl and decalcifying agents can be used to create dentine surfaces with varying compositions for interaction with endodontic sealers.
