Root Canal and Composite Filling Save a Damaged Tooth: A Case Study

What is it about?

The study presented a clinical case involving the endodontic treatment and direct Class II Composite restoration of a 29-year-old patient's maxillary first premolar with deep carious involvement and irreversible pulpitis. The methodology included a stepwise clinical protocol comprising access preparation, biomechanical cleaning and shaping, and obturation with gutta-percha under rubber dam isolation. Following successful endodontic therapy, the proximal defect was restored using a direct Class II Composite resin technique to achieve functional integrity and anatomical contour. The research confirmed optimal obturation and coronal sealing through postoperative radiographs, and the patient reported no postoperative discomfort. A follow-up at 6 months showed the tooth remained asymptomatic with intact restoration, demonstrating radiographic periapical healing and satisfactory functional outcomes. The study was conducted with the patient's informed consent, adhering to SCARE 2025 guidelines, and ethical approval was not required for this single case study.

Why is it important?

This study is important as it addresses the complex challenge of managing posterior teeth with pulpal involvement and proximal caries, which are common but demanding clinical scenarios. By documenting a stepwise protocol that combines endodontic treatment with direct adhesive restorative techniques, the research highlights a method to preserve tooth integrity and function without resorting to extraction. This approach not only ensures the elimination of infection and restoration of anatomical contour but also emphasizes the importance of a coronal seal in preventing reinfection. The findings provide a practical guide for dental practitioners to achieve long-term success in similar cases and underscore the critical role of combining endodontic and restorative disciplines to enhance patient outcomes. Key Takeaways: 1. Effective Root Canal Treatment: The study showcases a successful endodontic approach involving access preparation, biomechanical cleaning, and obturation with gutta-percha under rubber dam isolation, effectively eliminating infection and preserving the natural tooth. 2. Importance of Coronal Seal: Achieving a proper coronal seal through direct Class II composite restoration is crucial for preventing microbial recontamination and ensuring the long-term success of the root canal treatment. 3. Positive Clinical Outcome: The documented case demonstrated satisfactory obturation and restoration with no postoperative discomfort, highlighting the synergy between endodontic and adhesive restorative techniques in maintaining tooth integrity and function.
