| dc.description.abstract | 微笑是世界上的共通語言，但是想要擁有美麗的笑容必須搭配上一口潔白的牙齒。在醫美盛行的時代裡，社會大眾對於牙齒美白的需求越來越高，同時也刺激了牙齒美白技術的發展以及藥劑的開發。目前門診型的牙齒漂白藥劑的成分主要是以(30%~35%) 的過氧化氫，遠遠超過了美國食物及藥物管理局(FDA)規定的濃度，過去有學者利用低濃度的過氧化氫與光觸媒，並且加上高能量的紫外光(UV-Light)去照射，達到牙齒美白的效果，但是紫外光容易對眼睛造成傷害。本研究是利用光觸媒材料配合低能量可見光波長區段的LED光源，降低過氧化氫的濃度，達到治療的效果。 | zh_TW |
| dc.description.abstract | Smile is the common language of the world. If you want to have a beautiful smile, you got to have the bright teeth. Now, Aesthetic medicine is so popular that the public demand for tooth whitening is also increasing, which also stimulate the development of technology and the materials of teeth whitening. Currently, the main component (accounts for 30-35% ) of bleaching agent in dental clinic was hydrogen peroxide, which was far more than the regulation of the US Food and Drug Administration(FDA). In the past decade, some scholars use low concentration of hydrogen peroxide and photocatalyst, and coupled with the high-energy ultraviolet light(UV-light) to irradiate to whiten the tooth. However, UV-light might cause the damage of eyes. In our study, we use the photocatalytic materials with low energy LED light to reduce the concentration of hydrogen peroxide and to achieve the effect of treatment. | en |
