Abstract
OBJECTIVES: The current study aimed to investigate the influence of the periapical lesion size on healing outcome following Regenerative Endodontic Procedures (REPs) in mature teeth using cone-beam computed tomography (CBCT) and Mimics software. METHODS: The study included ten mature necrotic maxillary anterior teeth with periapical lesions ≥ 3 CBCT Periapical index score (CBCTPAI). REPs via blood clots were performed for all the teeth. CBCT scans were taken pre and postoperatively after 12 months follow-up periods and transferred to Mimics for volume measurements and comparison. Statistical analysis was performed using the Wilcoxon signed-rank test. RESULT: All teeth were symptom-free with a statistically significant decrease in the volume of the periapical lesion (P < 0.05) after 12 months except for one case. CONCLUSION: The study concluded that REPs could be a successful treatment modality for mature necrotic teeth with periapical lesions however the size of the preoperative periapical lesion could affect the outcome of the periapical healing. TRIAL REGISTRATION: The study was registered in ClinicalTrials.gov (ID: NCT04646538).
