Since 1970ʼs, application of a cast post system commenced in Japan, which enabled conservation of teeth that had previously been diagnosed the need for extraction. Since it was integrated into Japanese health insurance system in 1985, the number of these treatments has been multiplying, and it had been expected that there would continue to be an increase in the occurrence of root fractures. Investigation of etiology of permanent tooth loss by 8020 Promotion Foundation in 2005 reported that 11％ of tooth loss was due to root fractures. 4-META/MMATBB resin cement was developed in Japan in 1982, having high bond strength and excellent biocompatibility. This material was applied to adhesive treatment of vertical root fractures in the same year and has been demonstrating favorable result. This article focuses on development and evidence-based background of vertical root fracture adhesive treatment.
