Summary
Aim of the study:the aim of the study was the evaluation of the impact of electrical resistance of dental enamel on bleaching process.
Materials and methods: Extracted human permanent premolars were used in the study. Forty cubic samples with exposed enamel surfaces were prepared. Samples were polished, embaded in methacrylate and numbered. The electrical resistance values were measured before and after the implementation of whitening procedures by ECM IV system (LODE Diagnostics, Groningen, Holandia). Samples were bleached with 14% H₂O₂ Crest Whitestrips Supreme (Procter&Gamble, Cincinnati, Ohio, USA). The L*a*b* color parameters were measured by SpectroShade (MHT, Switzerland). The correlation between ECM values and the level of colour changes was evaluated.
Results: Spearman's rank correlation coefficient for baseline ECM values and mean percentage loss of L* and B* values were -0.54, and -0.63 respectively.
Conclusion: The results of the presented in vitro study revealed that several factors should be taken under consideration when the results of electrical resistance measurements are analyzed. ECM value could be a predictable factor for the assessment of susceptibility of dental enamel for bleaching process, but the further clinical study should be undertaken to confirm this relation.
