Objective: The aim of the present study is to evaluate the mineralization level of human enamel following bleaching treatment by using laser fluorescence device.


Methods: Forty five patients were divided according to the bleaching method used. Group 1: Chemical bleaching with 35 % hydrogen peroxide. Group 2: 35% hydrogen peroxide activated with 980 nm diode laser. Group 3: Bleaching with ozone. Levels of mineralization were measured with laser fluorescence device before bleaching, just after bleaching and also 14th, 30th days following the bleaching..


Results: Data were analyzed with Kruskall Wallis, one-way ANOVA and Mann Whitney U tests. The values were significantly higher compared to initial values following bleaching and at 2 weeks recall for groups 1 and 2 (p < 0.05). However, values returned to a similar degree with initial values at 4 weeks recall (p > 0.05). For group 3, values reduced significantly following bleaching (p < 0.05) while the values of each post-bleaching values were statistically similar (p > 0.05).


Conclusion: Both chemical and laser activated bleaching resulted in significant reduction in mineralization level while bleaching with ozone did not. Bleaching with ozone seems more safe in terms of demineralization compared to hydrogen peroxide.
