Summary
This study shows that periradicular surgery has a high success rate of 91.2% when using strict protocols and careful case selection for endodontic lesions.
Area of Science:
- Endodontics
- Oral Surgery
Background:
- Periradicular lesions of endodontic origin can present with or without inflammation.
- Predicting the prognosis of surgical interventions is crucial.
Purpose of the Study:
- To evaluate the long-term prognosis of periradicular surgery.
- To assess the outcomes of a rigorous surgical protocol with defined case selection.
Main Methods:
- 114 teeth with endodontic periradicular lesions were treated surgically.
- Standardized surgical techniques included flap reflection, curettage, root-end resection, ultrasonic cavity preparation, and IRM filling.
- Clinical and radiographic follow-up ranged from 1 to 4 years.
Main Results:
- A 91.2% success rate was observed in 102 teeth available for follow-up.
- Success was defined by the absence of clinical signs/symptoms and radiographic evidence of healing.
- Factors influencing success rate are discussed.
Conclusions:
- Adherence to a strict endodontic surgical protocol leads to predictable success.
- Contemporary techniques and materials contribute to favorable outcomes in periradicular surgery.
