Purpose. To evaluate the mineral ion loss of root dentine after treatment with 2% chlorhexidine solution (CHX) and to compare\nits yield and flexural strength (fs) after exposure to calcium hydroxide [Ca(OH)2]. Materials and Methods. Dentine bars (DB) were\nmade from 90 roots of bovine incisors and randomized into three groups: GControl: distilled/deionized water (DDW), GNaOCl: 2.5%\nsodium hypochlorite + 17% EDTA, and GCHX: CHX + DDW.The release of phosphate (PO4) and calcium (Ca) ions was measured\nby spectrophotometry. The DB were exposed to Ca(OH)2 paste for 0, 30, 90, and 180 days. DB were subjected to the three-point\nbending test to obtain yield and fs values. The fracture patterns were evaluated (20x). Data were analyzed using Kruskal-Wallis and\nDunn�s post hoc tests or one- and two-way ANOVA followed by Tukey�s post hoc test (
