It is commonly used throughout the world especially for the purpose of oral hygiene. Muslims are using asthe religious view. Current study aimed to test the ability of aqueous siwak extract to increase the resistance ofenamel surface against acid dissolution compared to sodium fluoride.Materials and Method: Twenty maxillary first premolars were treated with the selected solutions included twoaqueous siwak extract concentration(5%,10%) and sodium fluoride(0.05%)as control positive for 2 minutes once dailyfor 20days interval, de ionized water was used as control negative. The concentration of the dissolved phosphorusion was measured in etching solution of 2N HCL by flam atomic absorption spectrometer.Result: 10% aqueous siwak extract test solution was registered the lesser release of phosphorusion from etchedenamel surface, then 5% aqueous siwak extract followed by sodium fluoride 0.05%. No significant differencebetween two aqueous siwak extract concentration, while a significant difference was found between mentionedagents and sodium fluoride. De ionized water was recorded a highly significant difference with all test solutions.Conclusion: Aqueous siwak extract effective in increasing the resistance of enamel surface for acid dissolution andshould be use not only for the religious view but also for the benefit of its effects produced
