This study aims to evaluate the whitening efficacy and enamel effects of experimental bleaching gels containing 6% hydrogen peroxide, calcium polyphosphate (CaPP) submicroparticles, alkaline phosphatase (ALP), and violet LED activation. A total of 108 bovine enamel/dentin specimens will be distributed into nine groups, including a negative control (no treatment), a positive control using …
Commercial gel (Whiteness HP 35% and Whiteness HP35% Blue) will be added with remineralizing sub-microparticles of calcium polyphosphate (PPCa). PPCa is a promising compound and has biological activity comparable to hydroxyapatite, as it provides bioavailable calcium and phosphate ions to the surface of whitened enamel and improves physicochemical properties without affecting whitening ef…
The objective of this study was to evaluate in situ the physical properties of 10% Carbamide Peroxide (PC) associated with a Sulfonic Acid Copolymer (CPa) (Study I), to evaluate in situ the physical properties of dental enamel submitted to bleaching with 10% carbamide peroxide with natrosol thickener in patients with low salivary flow (Study II) and to investigate in situ the effectivene…

Hydrogen peroxide (HP)-based whitening gels have evolved, and new formulations have been proposed to reduce damage to the dental structure. A previous formulation was developed containing submicroparticles of calcium polyphosphate (CaPP) with good properties as a remineralizing whitening agent and biological compatibility. CaPP is a compound synthesized by the research group and is promis…
Objective: To evaluate, in vitro, the effect of whitening toothpastes Colgate® Luminous White Lovers (Wine) and Colgate® Luminous White Lovers (Coffee) directed to tooth staining with coffee and wine on the color, surface roughness and surface topography of tooth enamel . Methods: 130 blocks obtained from bovine incisors will be made, which will be randomly divided into 13 groups (n=10): …
Objective: To evaluate, in vitro, the effect of dentifrices containing tricalcium phosphate (beta-TCP) on hardness and color of the enamel, when used prior to home bleaching treatment, with 10% carbamide peroxide. Methods: 65 blocks of enamel/dentin will be made (4 x 4 x 2 mm) from bovine incisors that will be randomly divided into 5 groups (n=10), according to previous exposure of the to…
Calcium Polyphosphate Nanoparticles (CaPPNP) have recently been developed by adjusting the Ca:P ratio and have demonstrate to be an amorphous source of calcium and phosphate that would be essential for mineralization of dental tissues. Tooth sensitivity, soft tissue irritation, and alteration of enamel surface are the most commonly described side effects of tooth bleaching, thus, its elim…

Recently calcium-polyphosphate nano/microparticles (CaPP) have been developed through a co-precipitation method by adjusting the Ca:P ratio (2:1). CaPP can integrate to the tooth surface and release Ca2+ and PO43- to achieve bioinspired mineralization of the dental tissues, and this process is biologically upregulated by the enzymatic activity of Alkaline Phosphatase (ALP). Considering th…
