Abstract
Nanotube material that has been synthesized for decades is Titanium Dioxide Nanotube (TDN) because it has high photocatalytic properties and produces free radicals that can whiten teeth. Tooth whitening materials that are used in the public is such as H2O2 with high concentrations so that they endanger the health of tooth enamel. Therefore, this research uses TDN as a natural teeth whitening agent with low H2O2 concentrations. TDN is obtained from natural materials, mineral sand which is chemically processed using sodium hydroxide in an autoclave for 24 hours. The amount of free radicals is determined by ESR and the effect of teeth whitening determined by immersing the teeth in a 3% TDN and H202 solution and then characterized by the UV-Vis PC 2401 Spectrophotometer. The results showed that TDN produced O2 − free radicals which could degrade tooth color up to turned brighter.
