Dissolution of inorganic phosphorous ion from human enamel treated with different concentration of siwak aqueous extract in comparison with sodium fluoride

الملخص EN

Background : the use of Miswak, chewing sticks (salvadorapersica) can be traced back to Babylonians some 700 years ago.

It is commonly used throughout the world especially for the purpose of oral hygiene.

Muslims are using as the 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 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 phosphorus ion from etched enamel surface, then 5 % aqueous siwak extract followed by sodium fluoride 0.05 %.

No significant differen 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 used not only for the religious view but also for the benefit of its effects produced.
