Abstract: Fiber post has the advantages of beautiful appearance and excellent biosafety, which is widely used in clinical practice. However, it has limitations and failure rate, manifested as shortcomings like fiber post loosening, falling off, breaking, core damage and non-degradability. With the sustainable development of ecology, plant fibers have been widely used, such as coconut shell and bamboo fiber. Bamboo fiber has been paid close attention to by scholars due to its advantages including good mechanical properties, low cost, degradability, non-toxicity, anti-bacteria and good biocompatibility. Based on existing research, the mechanical and physical properties of bamboo fiber basically meet the requirements of dental post and core system. However, such studies are mostly non-medical experiments, and little research at home and abroad focuses on dental post and core system. This paper will further explore the application potential of bamboo fiber in dental post and core system in terms of mechanical and physical properties, anti-bacteria, cytotoxicity and biocompatibility of bamboo fiber. Moreover, related problems limiting application of bamboo fiber and possible improvement methods are proposed. It provides clinical guidance for the development of dental post and core system.
