Standard Root Canal Treatment

The rubber dam serves two main functions:

① Isolation

The tooth or teeth to receive treatment are isolated and exposed for the procedure, presenting better viewing and access.

② Barrier

The dam material protects against infection, thus increasing the success rate of RCT; it can also protect adjacent tissues from accidental injuries from caustic materials.

① RCT is conducted with enlarged vision of working area and improved LED lightening, thus chances of canal missing or files being broken inside canals can be reduced to the minimum.


② Insufficient pulpal wall planing and smoothing can’t remove all bacteria effectively, resulting in the failure of RCT, whereas excessive pulpal wall planing and smoothing can decrease the fracture resistance of roots. Moderate debridement plays an important role in long-term effect. Both proper equipment and rich experience in RCT work the best.


Insufficient obturation and Proper obturation and Excessive obturation

Warm gutta-percha obturation is the standard international root canal filling technique. It has better sealability than cold lateral condensation, and even the fine canals can be filled properly. This technique guarantees the high success rate of RCT.
