Influencing factors and detection methods of microleakage in root canal therapy

Abstract

Root canal therapy is a common and effective method to treat pulp and periapical diseases. Thorough root canal disinfection, good root canal shaping, perfect crown seal and apical seal are the keys to successful root canal treatment. The failure of root canal treatment can be attributed to the microleakage of bacteria and other irritants into the root canal and periapical tissues when the root canal system is not tightly filled. This paper will discuss the influencing factors of microleakage in root canal therapy and the research progress of microleakage detection methods.
