Abstract: Introduction: Calcium ions released from calcium hydroxide cements plays an important role in Protecting dental pulp complex and maintain its vitality through the stimulation of the formation of secondary/reparative dentin layer when directly contacted with the exposed pulpal tissues. Ca (OH) 2 cements release hydroxyl (OH) and calcium ions (Ca) upon its dissolution helping and its alkalinity reaches (PH 9 - 11) in favor of the cement to act as a barrier in protection of the pulp (1, 2, 3). Materials and Methods: 3 groups of calcium hydroxide cements were tested in this study. Each group composed of 10 specimens. Group I; self - cured Ca (OH) 2? Dycal (Dentsply Caulk, Milford, DE, USA). Group I; TheraCal (BISCO, Chicago, IL, USA) light - cured Ca (OH) 2and Group III; light - cured Ca (OH) 2 - Cal LC (PrevestDenpro Ltd., New Delhi, India). All specimens (n = 30) were prepared by mixing and curing the cements as per manufacturer?s instructions. Each sample was placed on the bottom of a 4 cm high test tube in 10 ml deionized water at 37?C. This stored water was collected for Ca analysis and replaced after 7, 14, and 21 days. In this manner, ion release was measured after 7, 14, and 21 days by inductively coupled plasma?optical emission spectroscopy test. Results: All calcium hydroxide cements release Ca ions yet, it was found that light - cured cements release higher Calcium ions than self - cured cements. TheraCal cement showed the highest amount of Calcium ions released in 21 days period and in all periods. Conclusion: within the limitation of this study, light - cured calcium hydroxide showed to have high amount of Ca ions released and TheraCalshown to be the highest cement in releasing Ca ions.
