Evaluation of the chelating effect of chitosan solubilized in different acids.

Aim: This study aimed to compare, through dentin microhardness and colorimetric analysis, the chelating effect of 0.2% chitosan solubilized in different acids.

Materials And Methods: The second and third cuts of the cervical region of maxillary central incisors were divided into four quadrants, resulting in eight specimens, which were treated with 50 μL of solution for 5 min according to their group ( = 10): GI - 0.

Analysis of the shelf life of chitosan stored in different types of packaging, using colorimetry and dentin microhardness.

Objectives: Chitosan has been widely investigated and used. However, the literature does not refer to the shelf life of this solution. This study evaluated, through the colorimetric titration technique and an analysis of dentin micro-hardness, the shelf life of 0.
