Summary
Apical endodontic surgery outcomes improved with ultrasonic systems compared to round burs, especially in molar teeth. This endodontic retreatment approach offers a higher success rate for complex cases.
Area of Science:
- Endodontics
- Oral Surgery
- Dental Materials
Context:
- Apical endodontic surgery is a common retreatment following conventional endodontic failure.
- Apical preparation methods include conventional round burs and endodontic ultrasonic systems.
Purpose:
- To compare the clinical outcomes of apical preparation using a conventional round bur versus an endodontic ultrasonic system in a randomized prospective clinical study.
Summary:
- A randomized prospective clinical study involved 399 patients undergoing apical endodontic surgery.
- Patients were randomly assigned to preparation with a conventional round bur or an ultrasonic system (P-max Newtron).
- One year post-treatment, 290 patients had follow-up data; the overall success rate was 71% for conventional burs and 81% for ultrasonic systems, with a statistically significant difference in molar teeth.
Impact:
- Ultrasonic systems demonstrate a higher success rate in apical endodontic surgery compared to conventional round burs, particularly for molar teeth.
- This finding may influence the choice of instrumentation for endodontic retreatment procedures.
- Improved outcomes can lead to better long-term tooth preservation and reduced need for further interventions.
