Patient Perception Between Two Emergency Treatments of Symptomatic Irreversible Pulpitis.

To evaluate in a comparative way the perception of the patient who comes with pain due to irreversible pulpitis in a tooth and who receives two types of treatment: complete pulpectomy (or control group) or pulpotomy (or experimental group). Prospective randomized and multicenter study. It will be carried out in 4 centers of similar socio-professional characteristics, with the same operative protocol. On a significant sample of emergency patients with a concrete clinical manifestation of symptomatic irreversible pulpitis, one type of intervention or another will be performed randomly. The data will be collected by means of a visual numeric scale (NRS). The null hypothesis is that both interventions provide the same reduction of pain in patients who present symptomatic irreversible pulpitis. All the patients who come to one of the private centers with irreversible pulpitis and who meet the defined criteria for inclusion and exclusion will be selected. The type of procedure that will be performed in the control group will be the complete removal of the pulp by means of a defined instrumentation technique, also called Pulpectomy. The procedure to be performed in the experimental group will be the removal of the pulp only at coronal level, also called Pulpotomy. The interventions will be assigned randomly and the "List Randomizer" (random.org) will be used for the randomization.
