Abstract:

Root canal treatment mainly aims to eliminate microorganisms from the contaminated root canal system. Calcium hydroxide have anti-bacterial properties, can dissolve necrotic tissue, inhibit root resorption and induce hard tissue formation and has little side effect. Thus, calcium hydroxide as an intracanal medicament is commonly used to control root canal infection in clinical practice. However, considering the complex anatomy of the root canal system and the influence of calcium hydroxide vehicles and irrigation equipment, the complete removal of calcium hydroxide in root canal is hard. The residual calcium hydroxide influences the sealing of root canal filling and reduces the fracture resistance of teeth. Therefore, the success rate of root canal treatment is influenced. This paper reviews factors leading to the residual of calcium hydroxide and the influence of residual calcium hydroxide on root canal treatment.

Key words: calcium hydroxide, root canal treatment, infection control
