Why it matters for dental
Endo-perio lesions are a high-risk diagnostic category that can lead to unexpected tooth loss; this study supplies survival data that endodontists, periodontists, and restorative dentists can use when deciding whether to retain or extract questionable teeth.
Key points
- Retrospective cohort of 1289–1300 teeth treated for combined endodontic-periodontal lesions at a university clinic.
- Tooth survival assessed up to August 2026, providing multi-year outcome benchmarks for treatment planning.
- Findings directly inform referral timing between endodontic and periodontal specialists when both pulpal and periodontal pathology coexist.
- Data can be cited in informed-consent discussions with patients weighing retreatment versus extraction and implant replacement.
