Summary
Intraoperative root canal fillings after apicoectomy show better success rates than preoperative fillings. Titanium and amalgam fillings demonstrated superior outcomes compared to other materials, especially in orthograde and retrograde applications, respectively.
Area of Science:
- Endodontics
- Oral Surgery
- Dental Materials Science
Context:
- Apicoectomy is a surgical procedure to treat endodontic failures.
- Retrospective analysis of 799 apicoectomized teeth with a mean follow-up of 4.2 years.
- 3,524 apicoectomies were analyzed to evaluate treatment outcomes.
Purpose:
- To compare the success rates of different root canal filling techniques (preoperative, intraoperative orthograde, intraoperative retrograde) in apicoectomized teeth.
- To evaluate the influence of various filling materials on treatment success.
- To assess prognostic factors affecting apicoectomy outcomes.
Summary:
- Intraoperative orthograde root canal filling (51.3%) demonstrated a significantly better success probability than preoperative filling (25.0%).
- Titanium fillings in orthograde application and amalgam in retrograde application showed higher success rates.
- Maxillary anterior teeth had the highest success rate, while preoperative endodontics resulted in unfavorable outcomes.
Impact:
- Findings suggest intraoperative orthograde filling is a favorable technique for apicoectomy success.
- Highlights the importance of material selection in endodontic surgery.
- Provides evidence-based insights for optimizing apicoectomy procedures and improving patient prognosis.
