Conditioning factors such as time, size, location, inappropriate disinfection and sealing, are indispensable to achieve acceptable long-term outcomes. Calcium silicate cements are bioactive materials used for perforation repair. They can be set in moist environments such as blood, saliva and dentinal fluid making them a reliable material for clinical applications. This case report describes the treatment and repair after a 16-month follow-up of a lateral root perforation of the maxillary lateral incisor.展开更多

In recent years, the research on C_2S has been attached importance to and has achieved obvious success, especially in the study of the match phase of C_2S solid solution, many cement systems with fine characteristics have been formed. It shows it's quite easy for C_2S to match other minerals, which plays an important role in saving energy, improving cement properties and developing new cement materials. The broad propspects are revealed in C_2S studying area.展开更多
