Research Progress in Biomimetic Materials for Human Dental Caries Restoration

Tooth decay is a common and frequent oral disease seriously affecting the quality of people's lives. According to the 2012 report by WHO, 60–90% of school children and nearly 100% of adults have had tooth decay. Hence the prevention and treatment of tooth decay are urgent and necessary. This chapter presents the basic knowledge regarding the structure of the natural human tooth and the formation mechanism of tooth decay, followed by the introduction of hydroxyapatite (HA)-filled biomimetic resin composites for caries treatment. Above all, novel biomimetic materials and methods of constructing enamel-like microstructure are reviewed.
