Abstract

Background: Chronic apical periodontitis is a common endodontic condition with silent progression and potential complications if inadequately treated. Bioceramic-based sealers have shown antibacterial properties and the ability to promote periapical healing. Objective: To evaluate the treatment outcomes of root canal treatment in permanent incisors with chronic apical periodontitis. Materials and Methods: A cross-sectional study was conducted on 60 permanent incisors from 46 patients at Can Tho Eye and Odonto-Stomatology Hospital. The teeth underwent root canal treatment, obturation with NeoSealer Flo, and were evaluated clinically and radiographically using CBCT immediately after obturation and at 6 months post-treatment. Results: After 6 months, 98.3% of patients had normal mastication; sinus tract/swelling and percussion pain were observed in only 1.7% of teeth (p<0.05). CBCT evaluation showed 31.7% of teeth achieved PAI 0 (complete healing), with 63.4% demonstrating complete or ongoing healing. Lesion diameter significantly decreased from 5.8 ± 2.1 mm to 2.0 ± 1.9 mm (p<0.001). Conclusion: Root canal treatment of permanent incisors with chronic apical periodontitis achieved high effectiveness after 6 months. Sequential irrigation, calcium hydroxide medication, and obturation with the biocompatible sealer NeoSealer Flo were critical to periapical healing and clinical recovery.
