Purpose This review integrated the current literature on diffusion of whitening agents, their
interactions with stain molecules, and changes to the surface, with the aim of establishing a …

This review highlights the recent advances in X‐ray microcomputed tomography (Micro‐CT)
applied in dental research. It summarizes Micro‐CT applications in measurement of enamel …

Abstract Hydrogen peroxide (H 2 O 2) is a powerful oxidising agent. It gives rise to agents
known to be effective bleaching agents. The mechanisms of bleaching involve the …

Objectives: The mechanism of tooth bleaching using peroxide oxidizers is not fully
understood. It is unknown whether peroxide radicals make teeth whiter by deproteinizing …

Background Tooth sensitivity has been reported with in-office tooth bleaching. The authors
conducted a study to evaluate whether the use of a desensitizing agent before in-office …

The aim of the study was to investigate changes in the micromorphologyl and
microhardness of the enamel surface after bleaching with two different concentrations of …

This study investigated the influence of pH values of bleaching agents on the properties of
the enamel surface. Sixty freshly extracted premolars were embedded in epoxy resin and …

This study investigated the effect of two bleaching agents, 16% carbamide peroxide (CP)
and 35% hydrogen peroxide (HP), on the mechanical properties and protein content of …

Although teeth microcracks (MCs) have long been considered more of an aesthetic problem,
their exact role in the structure of a tooth and impact on its functionality is still unknown. The …

Objective This study evaluated the differences in enamel color change, surface hardness,
elastic modulus, and surface roughness between treatments with four bleaching gels …
