A carbonated beverage (Coca Cola, Pakistan ltd) will be used for artificial white spot lesion formation. The pH of the beverage will be 4-4.5 at 37ºC. The teeth will be immersed in demineralization solution for 4 weeks before treatment. The solution will be changed every 48 hrs. to keep the pH constant. After demineralization specimens will be washed with distilled deionized water (DDW). The tooth will have a white spot lesion only on the buccal surface. A sufficient amount of 5% bioactive glass (Biomin F T/P) was applied on the tooth surface for three minutes using a tooth brush. The toothpaste remained on the surface for an additional 30 minutes.

After demineralization specimens was washed with distilled deionized water (DDW). The tooth would have a white spot lesion only on the buccal surface. The teeth were cleaned and dried first. 5% Sodium fluoride (Enamelist) varnish was applied on tooth surface with disposable tooth brush. The varnish remained undisturbed on teeth for 4 hours.
