Summary
Endoscopic visualization during periradicular surgery (apicoectomy) showed a higher success rate (88.9%) compared to traditional methods (75.4%). Further studies are needed to confirm if endoscopy improves outcomes in endodontic microsurgery.
Area of Science:
- Endodontics
- Oral Surgery
- Medical Imaging
Background:
- Periradicular surgery, including apicoectomy, aims to treat persistent periapical lesions.
- Intraoperative visualization is crucial for the success of these procedures.
- Traditional methods like micromirrors may have limitations in visualizing surgical sites.
Purpose of the Study:
- To evaluate the effectiveness of intraoperative endoscopy as a visualization aid in periradicular surgery.
- To compare the success rates of apicoectomies performed with endoscopic guidance versus conventional techniques.
Main Methods:
- A prospective clinical study involving 129 teeth undergoing periradicular surgery.
- Test group (62 teeth): Endoscope used for root-end resection, cavity preparation, and retrograde obturation.
- Control group (67 teeth): Micromirrors used for intraoperative diagnostics.
Main Results:
- Success rates after one year: 88.9% in the endoscopy group vs. 75.4% in the control group.
- Clinical and radiographic assessments categorized outcomes as success, uncertain healing, or failure.
- No statistically significant difference was found between the two groups despite the observed difference in success rates.
Conclusions:
- Endoscopy demonstrated a higher success rate in periradicular surgery, though not statistically significant in this study.
- Further research is warranted to determine the definitive impact of endoscopy on periradicular surgery outcomes.
- Endoscopic visualization may offer potential benefits for improving surgical precision and success rates.
