Clinically, it is not recommended to fill the tooth directly after pulp inactivation, and it is necessary to carry out perfect root canal treatment first, to completely remove the infected material in the root canal, and then carry out filling or restorative treatment. If the infected material is not removed from the root canal, a direct filling may lead to re-infection of the root canal.
