Abstract
(1) Background: What is the effect of 16% and 40% concentration bleaching agents on dental structures in healthy patients compared to predialysis patients? (2) Methods: Forty teeth were included in the study (20 from healthy patients and 20 from predialysis patients). Each group was randomly divided into another two subgroups (n-10), depending on the bleaching agent concentration (16% and 40% gels). Color parameters were registered before and after the whitening process using a spectrophotometer. To determine enamel ultramicroscopic modifications, SEM and AFM analysis were performed before and after bleaching. (3) Results: An increasing trend was identified in the average values of ∆E and ∆L within the groups of predialysis teeth between teeth whitened with 40% concentration gel and those whitened with 16% concentration gel, while for the enamel samples from healthy patients the trend was reversed. The average values for roughness in the case of the two bleaching agents in healthy and predialysis teeth presented statistically significant differences (p < 0.05). (4) Conclusions: The effects of bleaching agents are less significant on teeth from predialysis compared to healthy patients. A direct link exists in terms of the clinical effect between the concentration of the whitening gel and color modifications.

The researchers concluded that the negative effects of whitening gel with 16% carbamide peroxide on the dental substrate of uremic patients was less harmful and destructive compared to the effects on the teeth of healthy patients. Based on these results obtained by Mahmoud et al [4], the current study aims to investigate the effects of whitening treatment on the dental tissues of patients with chronic kidney disease, but in the stage of predialysis

Summary
The use of different whitening techniques has attracted the interest of dental professionals, since these are relatively non-invasive and easy to perform. Contemporary bleaching systems are mainly based on hydrogen peroxide or one of its precursors, carbamide peroxide. These are often used in combination with an activating agent such as light or heat. Whitening agents can be applied to the external surface of the teeth (vital whitening) or inside the pulp chamber (non-vital whitening). Both techniques aim to whiten the chromogens inside the dental tissue, changing the tooth color [1].
