Dental enamel Ca+ and sr+ ions were analyzed using x-ray fluorescence
We aimed in our research to study the effect of one application of high concentration of bleaching materials (CP 45%, HP 40%)-which contains sodium fluoride & potassium nitrate-on the mineral content of dental enamel (ca+, sr+ ions)
20 Sound Extracted human premolars with no caries were stored in distilled water at room temperature prior to the experiment, Distributed into two groups (10 teeth: its buccal surfaces were bleached by one application of 40 minutes of HP (pf) 40%, 10 teeth: its buccal surfaces were bleached by one application of 45 minutes of CP (pf) 45%).every studied enamel surface was grinded, the lingual surface of each tooth was the control sample for its buccal bleached surface. The powder taken from each enamel surface of each sample was analyzed using x-ray fluorescence which depends on electronical beam projection on enamel powder and reading results on XRF instrument screen
There was no statistical differences between ions average of bleached and control samples of dental enamel. There was no difference between HP and CP samples
.One application of HP 40% & CP45% bleaching materials doesn’t affect dental enamel ca+ & sr+ ions
