Eligibility

Age
18 Years to No maximum

Inclusion criteria

Inclusion criteria: Patients: healthy (ASA I classification); over 18 years of age; asymptomatic; indication for endodontic treatment of manbidular molar (first or second). Dental element: pulp necrosis; negative response to the cold pulp sensitivity test; radiographic image compatible with a radiolucent periapical lesion of origin endodontic.

Exclusion criteria

Exclusion criteria: Patients: who have some type of comorbidity; smokers; pregnant; under 18 years old; who have used medication that may alter the perception pain, such as analgesics or anti-inflammatory, at least 48 hours before the procedure, and use of antibiotics 30 days before treatment. Dental element: prior manipulation of root canals; associated periodontal lesion; interradicular furcation lesion; mobility above grade I; presence of fistula, abscess or edema; calcified or internally resorbed root canals; roots with a degree of curvature greater than 45 degrees; incomplete root formation; C shaped internal anatomical conformation; widely destroyed crown that makes absolute isolation and/or restoration impossible immediate finish with composite resin.

Design outcomes

Primary

MeasureTime frame
It is expected to find a 10% difference in the comparison of success rates between the control and intervention groups after 12 months of follow-up.

Secondary

MeasureTime frame
It is expected to find no difference in the prevalence (% patients who had postoperative pain) and in the intensity of postoperative pain between the control and intervention groups, at the following times: 2h, 12h, 24h, 48h, 72h and 7 days after endodontic treatment.
