Markedly Effective: Post-treatment X-ray examination shows complete resolution of the periapical radiolucency. The patient's chewing function is largely restored, and symptoms such as gingival swelling/pain, tooth discoloration, and occlusal discomfort have disappeared.

Effective: Post-treatment X-ray examination shows significant reduction in the size of the radiolucency. The patient may experience mild percussion pain or discomfort. Chewing function is largely normal, and symptoms such as gingival swelling/pain, tooth discoloration, and occlusal discomfort show improvement.

Ineffective: Post-treatment X-ray examination shows no reduction or even enlargement of the radiolucency. The patient reports significant percussion pain. Symptoms such as gingival swelling/pain, tooth discoloration, and occlusal discomfort show no improvement.

Four distinct clinical assessments to be evaluated at 3, 6, 12, and 24 months postoperatively: tooth mobility, assessed clinically using a standard grading scale (Miller index. Grade I: Mobility with a buccolingual displacement of ≤1 mm; Grade II: Mobility with a buccolingual displacement of 1-2 mm, possibly accompanied by slight mesiodistal mobility; Grade III: Mobility with a buccolingual or mesiodistal displacement exceeding 2 mm, or the presence of vertical mobility.) ; periodontal probing depth, measured at designated sites(mesiobuccal, midbuccal, distobuccal mesiolingual, midlingual, distolingual).) around the tooth with a periodontal probe and recorded in millimeters; percussion pain, evaluated by vertical and horizontal tapping and documented either as a binary presence/absence; the presence of a sinus tract, determined through visual inspection and verification with a gutta-percha point if necessary and recorded as a binary outcome. Each parameter will be analyzed independent
