Patient Perception Between Two Emergency Treatments of Symptomatic Irreversible Pulpitis.
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.
Clinical procedure will be the same in both groups with regard to the anesthetic technique,
 and the cavity access and provisional closure of the aperture. The characteristics of both
 interventions will be described in detail in order to homogenize the procedures. The patient
 will be conveniently informed before requesting his/her Informed Consent for his/her
 voluntary participation in the study. Their identification data will be treated in accordance
 with the provisions of Regulation (EU) 2016/679 of the European Parliament and Council of
 April 27, 2016, and the Organic Law 3/2018 of 5/12, currently in force, will remain in
 custody at the Center where they receive treatment and will not be shared by the other
 centers of the study.

 The patient will not be aware of the type of procedure he has been assigned for and will
 express in a numerical scale according to his perception of the pain on 4 occasions: before
 starting treatment, at 8-12, 24 and 72 hours after treatment. Likewise, right after receiving
 the treatment, he will answer some questions related to the degree of comfort during the
 treatment and about his perception of the time of the intervention.

 Data sheets will be collected and treated statistically.
