Abstract
Dental bleaching is considered a conservative and biologically safe treatment for discolored teeth. Despite this, one of the major undesirable effects of bleaching is dentin sensitivity which may occur during and after treatment. To address these sensitivity issues, new dental bleaching preparations with lower concentrations of hydrogen peroxide (H2O2) have recently been introduced to the market. This paper presents a clinical case report of a 20-year-old female patient admitted to the Araraquara Dental School, UNESP, Brazil. The patient underwent dental bleaching using one of the new products with reduced hydrogen peroxide concentration, Lase Peroxide Lite 6%, a 6% H2O2 gel containing titanium oxide nanoparticles doped with nitrogen (6% H2O2/N-doped TiO2).
Highlights
It is known that the diffusion of H2O2 through the dentin depends on the concentration of the gel, the period of time that the agent is in contact with the tooth [13], and the thickness of the dental structure [8, 14]
It was believed that a high concentration gel and long contact time with dental structure would be required to obtain greater efficacy with bleaching procedures [9, 21]
The use of 15% H2O2/TiO2 photocatalyzed by LED was recently reported and demonstrated that, besides having lower sensitivity compared to products with 35% concentration, this preparation provided greater bleaching efficacy [8, 9, 16, 17, 20]
Summary
The demand for aesthetic dentistry has increased continuously [1,2,3,4], and the smile’s appearance has become an important part of the social attractiveness of a person and their interactive communication skill [1, 2, 4, 5]. Sensitivity issues have led some manufacturers to release bleaching gels with lower concentrations of H2O2 in order to minimize the side effects produced by peroxide radicals [9, 13, 17] Aiming to increase both efficacy and safety, new bleaching agents with lower concentrations of H2O2 based on the catalytic action of a nanoparticle semiconductor additive such as titanium dioxide (TiO2) activated by light sources [9, 16,17,18,19,20] are entering the market [4, 9, 13, 16,17,18,19,20]. This study aims to present a case report using this new product
