abstractsThe success rate of root canal therapy(RCT) have been improved continuously along with the advancement in RCT techniques in the past several decades.If standard procedures of modem RCT techniques are strictly followed,the success rate of RCT may exceed 90％.The success of RCT is mainly affected by such factors as clear concept of the anatomy of root canals,proper mechanical and chemical preparation and perfect filling of root canal system.If these factors are sufficiently noted,a success is easy to achieve.Even though the primary RCT fails,retreatment can further be conducted to save the diseased teeth.
