Pulp congestion is also known as clinically reproducible pulpitis, which is treated as follows: 1. If reproducible pulpitis is caused by deep caries, it is generally recommended to carefully remove the decayed material and appease the pulp with materials that appease the pulp, such as calcium hydroxide or zinc oxide clove oil paste. After 2-4 weeks, if the symptoms appear to have disappeared, then a permanent filling should be made; if the affected tooth develops obvious hot and cold pain or spontaneous pain during this period, root canal treatment should be carried out; 2. For reproducible pulpitis due to occlusal trauma, the traumatized tooth should be carefully regraded and ground to try to alleviate its (occlusal) force, and the state of the pulp may be restored to normal; 3. For reproducible pulpitis due to excessive orthodontic external forces, it is recommended to carefully remove the decay material, to pacify the pulp with materials such as calcium hydroxide or zinc oxide-butyl oil paste. Reproducible pulpitis, to reduce the orthodontic force appropriately; 4, for some atypical atypical reproducible pulpitis, when the symptoms and reproducible pulpitis is difficult to distinguish, the principle of treatment is generally also according to the reproducible pulpitis of the treatment. Pacifying treatment is carried out first, and if there is no pain, it is also possible to fill; if obvious pain occurs, root canal treatment is carried out.
