Design outcomes
Secondary
| Measure | Time frame |
|---|---|
| Expected Outcome 1: Changes in the PAI index 6 months after treatment; verified by means of periapical index scores attributed to each tooth in the periapical radiographs at each of the evaluation times; from the comparison of the mean values of the scores between the evaluation times;Expected Outcome 2: Radiographic quality of endodontic obturation; verified by periapical radiographs after completion of the treatment, taking into account the parameters apical extension, homogeneity and conicity; from the proportion of endodontic obturations classified as "perfect"; "satisfactory" and "deficient";Expected Outcome 3:Incidence of postoperative pain and its severity at 24, 48, 72 hours and 7 days; verified by means of verbal scale (incidence) and visual analogue scale (severity) from the proportion of patients who affirm that postoperative sensitivity has occurred and the calculation of mean severity indicated in the visual analogue scale | — |
