Background: Chitosan is a natural substance recognized for its properties of biocompatibility and biodegradability. The present study was conducted to determine chelating ability of chitosan in different acids. Materials & Methods: The present study was conducted on 20 freshly extracted non carious periodontally weak mandibular central incisors. Teeth were sectioned 3dentin slices of 1 mm of thickness each were obtained. The 0.2% chitosan solutions were distributed to 4 groups. Dentin microhardness was evaluated in each solution. Results: In group I, specimens were solubilized in 1% acetic acid, group II were solubilized in 3.3% citric acid, group III were solubilized in 0.00145% hydrochloric acid, and group IV were solubilized in distilled water (control). The ability to reduce dentin microhardness of the solutions were 42.5 in group I, 53.1 in group II, 57.2 in group III and 88.7 in group IV. The difference was significant (P< 0.05). Conclusion: Authors concluded that chitosan solubilized in acetic acid, followed by chitosan in citric acid, provided a greater reducing effect compared to distilled water.
