Objectives: To compare the side effects of typical whitening treatments (by means of oxidation) compared to the new treatment developed by the authors through reduction. The aim is to provide information about the chemical interactions of the encapsulated reductant agent (metabisulfite, MBS) with the enamel structure compared with carbamide peroxide (CP) and to study their penetration in the hydroxyapatite (HAP) and the changes produced in the mineral and its hardness.

146 p, 16.9 MB A novel approach for tooth whitening : liposome-encapsulated reductant. In vitro efficacy studies and characterization of the treated teeth including synchrotron techniques / Babot Marquillas, Clara ; Valiente Malmagro, Manuel, dir. ; Sánchez Martín, Ma. Jesús, dir.
En aquesta tesi es conceptualitza, desenvolupa i optimitza un tractament blanquejant per a la seva aplicació a la cavitat oral, basat en un enfocament diferent a la oxidació. També s'estudien els seus efectes sobre l'estructura dental. [...]
En esta tesis se conceptualiza, desarrolla y optimiza un tratamiento blanqueante para su aplicación en la cavidad oral, basado en un enfoque diferente a la oxidación. También se estudian sus efectos sobre la estructura dental. [...]
In this thesis, a treatment based on a different approach is conceptualized, developed and optimized for its application in the oral cavity. Also, its effects over the tooth structure are studied. It was hypothesized that the reducing agent sodium metabisulphite (MBS) had whitening action over the tooth stains, by saturation of the conjugated double bonds. [...]
