Dissolution of inorganic phosphorous ion from human enamel treated with different concentration of Siwak aqueous extract in comparison with sodium fluoride
Main Article Content
Abstract
Materials and Method: Twenty maxillary first premolars were treated with the selected solutions included two aqueous siwak extract concentration(5%,10%) and sodium fluoride(0.05%)as control positive for 2 minutes once daily for 20days interval, de ionized water was used as control negative. The concentration of the dissolved phosphorus ion 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 etched enamel surface, then 5% aqueous siwak extract followed by sodium fluoride 0.05%. No significant difference between two aqueous siwak extract concentration, while a significant difference was found between mentioned agents 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 and should be use not only for the religious view but also for the benefit of its effects produced.
