稀土元素应用于牙齿组织修复的研究进展

Teeth own several functions such as promoting food digestion, helping pronunciation, and maintaining facial harmony and beauty. As people pay more attention to dental care, the composition and structure of teeth, as well as the causative factors and processes that lead to the damage of dental tissues, have been widely investigated in recent years. In order to eliminate these negative effects of caries, tooth loss and malformation on people’s lives, some effective techniques including broken dental tissue repairs, dental implants and orthodontics are developed to restore the function and aesthetic properties of teeth. Some studies show that, some rare earth elements could participate in the mineralization and preparation of dental materials which can significantly improve the performance of the dental materials used for dental tissue restoration. In this review, we introduces the current research progress in rare earth elements in caries prevention, dental tissue restoration and orthodontics, analyzes the role of rare earth elements in the process of dental tissue restoration, puts forward scientific and reasonable suggestions, and outlooks the future development direction of rare earth elements applied in dental tissue restoration.
