Inclusion criteria
Inclusion criteria: Patients aged 18 to 50 diagnosed with irreversible pulpitis and pulp necrosis in molars that do not show symptoms before starting treatment will be selected for the study.The root canals of the teeth to be treated should present curvature of up to 25 ° measured according with the Schneider method (Schneider, 1971).

Exclusion criteria: Ingestion of any type of medication before treatment; presence of internal or external resorption; periapical pathology; lockjaw; ankylosis; periodontal index score less than 3; systemic disease; Bad severe tooth position; history of trauma; pregnancy; Bad severe occlusion associated with traumatic occlusion; anterior teeth; lack of patient compliance; intolerance history of the anti-inflammatory drugs nonsteroidal; and the presence of teeth that require endodontic retreatment, pre-operative pain.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Expected Primary endpoint is the presence of postoperative pain after endodontic treatment in two groups (A Reciproc Technique and B Protaper Next Technique), the pain presence is evaluated using NRS -10 and VAS scale for evaluation the post-operative pain levels (6h, 12h, 24h, 2nd to 7th days), and devices for evaluating pain perceived on vertical percussion. The overall absolute risk of spontaneous POP and POP after vertical percussion between the instrumentation techniques were compared. Intragroup (ProTaper and Reciproc) analysis of the POP intensity in the different time intervals of evaluation was performed, followed by evaluation between each time interval. The POP intensity was compared between the groups for the post-preparation time intervals (a=0.05). The intensity of pain experienced by patients after endodontic treatment in the Reciproc group was similar to those in the ProTaper Next group (p > 0.05). In both groups, the highest levels of postoperative pain were recorded 24 h after each procedure, but these levels decreased after 72 h and 7 days after endodontic therapy, although differences were not significant (p = 0.55). | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcomes were the pos operative pain (POP) intensity, time of instrumentation of each technique, consumption of analgesics after root canal preparation, and the POP perceived on vertical percussion. | — |
