Abstract

To measure the efficacy of the whitening effect of non-oxidizing and non-acidic nano-and micro-hydroxyapatite materials on the enamel surface and to evaluate the surface changes after treatment. Methods: Three hydroxyapatite suspensions and two hydroxyapatite mixtures in dissolvable polymer films were applied to a total of 30 extracted caries-free human premolars. After the last material application, a hydrodynamic shear force was generated and applied for 2 minutes to all teeth to simulate mechanical loading of the surface. The tooth color was measured with a dental spectrophotometer. The mean changes of the L*a*b* values between different measurements in each group were expressed as δE and were analyzed with ANOVA and the Tukey's post-hoc test. Results: The groups of the nano-hydroxyapatite, the hydroxyapatite-nanocrystals and the tricalcium-phosphate exhibited significant δE values between baseline and after hydrodynamic shear force application (P< 0.05). In conclusion, the materials used in the study are very promising alternatives to oxidizing bleaching agents. (Am J Dent 2009;22:23-29).
