Abstract

Introduction: Regarding routine application of bleaching treatment in dental practice, this study aimed to determine effect of in-office and at-home bleaching and also a combination of methods on human ENAMEL, using FT-IR spectroscopy.Method and materials: For fifteen non-carious human molars, after prophylaxis with pumice, each tooth was sectioned bucco-lingually. One pieces of each tooth was bleached. For first group in-office bleaching, for second group at-home bleaching, and for third group combination of in office and at-home bleaching was done. Samples were stored in distilled water. Then ENAMEL of teeth was powdered with a high-speed rotary instrument. Spectra of powdered ENAMEL were taken for each sample. The data were analyzed with paired-t and Kruskal-Wallis tests (a = 0.05).Results: On comparing the infrared spectra of non- treated and treated specimens, no structural changes were detected in ENAMEL, but the difference in intensity of phosphate between bleached control sample for in-office bleaching was statistically significant (p value < 0.05). In at-home bleaching and combination of in-office and at-home bleaching, difference in intensity of phosphate and carbonate in treated and non treated specimens was not statistically significant. The difference of intensity of phosphate and carbonate in 3 groups in samples was not statistically significant.Conclusion: In office bleaching agent was capable of reducing mineral content ENAMEL, which may be caused by high concentration of CARBAMIDE PEROXIDE. There was no reduction in mineral content of ENAMEL in the presence of fluoride in at-home and combination of at-home and in-office bleaching.
