Experimental Solution of Chitosan and Nanochitosan on Wettability in Root Dentine: Model Prior Regenerative Endodontics.

Aims: To compare the effect of CS and CSnp on the wettability in root dentine with other irrigation protocols with an experimental model prior regenerative endodontics. . An experimental study that included eighty hemisected human root distributed into 8 groups: G1- distilled water; G2- 1% NaOCl/17% EDTA; G3- hypochlorous acid 0.
