Design outcomes

Primary

MeasureTime frame
1. Postoperative pain measured using the visual analog scale (VAS) before treatment, 1, 3, 7 and 14 days 2. Swelling and tooth mobility measured according to their presence/absence before treatment, 1, 3, 7 and 14 days 3. Apical lesion volume and density measured using CBCT images before treatment, 6, and 12 months

Secondary

MeasureTime frame
Percentage of apical lesions healing measured using CBCT images by comparing the baseline with 6, and 12 months follow-up images
