Root canal treatment for C-type roots is more complicated because C-type roots have greater variability, more traffic in the root canal, and the secondary and lateral root canals are more complex, and the root canals are more curved, so it is recommended to go to a regular major hospital for root canal treatment if the patient has a C-type root canal.It is very easy to miss a root canal in a C-type root canal because the opening of the root canal is not fixed, sometimes it is a small root canal opening with a large C-type, and it is difficult to clearly identify whether a root canal is missed when probing with specialized oral instrumentation.C-type root canal must be filled with hot cement, because the root canal system is very complicated, and it is possible to miss the root canal with the cold cement. It is very easy to miss the root canal because the C-shaped root canal is not fixed, sometimes it is a small root canal with a large C-shaped opening, and it is difficult to find out whether the root canal has been missed when it is probed with the professional instruments in the oral cavity.C-shaped root canals should be filled with hot cement because the root canal system is very complicated, and the use of cold cement is very likely to miss the lateral root canals as well as the collateral canals, which will lead to inflammation of the root in the later stage.
