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

Figure 3

Representative SEM photographs from the cervical and apical thirds, at 1.000×, 2.000×, or 5000×, of each group: visible dentinal tubules were seen in the samples treated with 1% NaOCl+17% EDTA; 1% NaOCl+0.025% HOCl+17% EDTA; 1% NaOCl+0.2%CS; and 1% NaOCl + CSnp. Greater tubular diameter is seen in f, i, and o. Greater number of tubules per field is seen in h, n, and t. Intertubular dentin appearance is seen in l, o, r, and u.
