Summary
Periapical surgery on posterior teeth has a limited success rate of 62%. Delayed infections were the primary cause of failure, highlighting the need for extended post-surgical monitoring.
Area of Science:
- Endodontics
- Oral Surgery
Background:
- Periapical surgery for posterior teeth is infrequently studied.
- Limited data exists on the efficacy and outcomes of apicectomies in this region.
Purpose of the Study:
- To evaluate the success rate of periapical surgery (apicectomy) on posterior teeth.
- To identify common failure modes and influencing factors.
Main Methods:
- Retrospective analysis of 32 apicectomies performed on posterior teeth.
- Assessment using both clinical and radiographic evaluations.
Main Results:
- A 62% success rate was observed for posterior tooth apicectomies.
- 16% of cases failed, with most failures presenting as delayed infections (3-6 months post-surgery).
Conclusions:
- Post-surgical follow-up of at least six months is crucial for assessing outcomes.
- Anatomical challenges and the role of retrograde fillings in posterior tooth apicectomy warrant further discussion.
