Abstract
Introduction: The aim of this study was to evaluate desensitizing solutions which were made tannin acid ion and various metal ion oxides. Aesthetically improved vis-à-vis significant bioremineralization of the hydroxyapatite (HAp) crystals for the treatment of dentinal hypersensitivity has been explored following the tanin acid-metal (ions and oxides) complex mediated mineralization.
Methods: Demineralized human molar disks were treated with TA combined with 6 different daily intake metal ions and metal oxide namely Sr(NO3)2, SiO2, Fe2O3, TiO2, CaCl2, and VCl3 in separate experiments. The samples were coated in the complex solution for 4 min followed by immersion in artificial saliva for 7 days. Biomineralized HAp crystals were well characterized by Field Emission Scanning Electron microscope (FE-SEM), Transmission Electron Microscope (TEM), Scanning Electron Microscope (SEM) and Selected Area Electron Diffraction (SAED).
Results: TA-Sr(NO3)2 TA-TiO2 exhibited the most significant results by occluding the Ca. 79% and 68% dentinal tubules, respectively with brighter color changes after treatments.
Conclusions: TA combined desensitizing solutions had improved aesthetics of the exposed dentin by its whitening effect using chemically inert and biocompatible, Sr and Ti oxides which may be potential to develop facile at-home aesthetically effective dentin hypersensitivity solution.
