Abstract

Concurrent endo-perio lesions often arise due to the complex interaction between endodontic and periodontal tissues, making it challenging for clinicians to diagnose the underlying lesions and their causative factors accurately. Iatrogenic injury, an often overlooked cause, can significantly influence diagnoses and treatment outcomes. This clinical trial aims to explore the iatrogenic factors contributing to such lesions, focusing on how procedural errors like over-instrumentation, inadequate root canal filling, and surgical procedures create a foundation for the development of these complex endo-perio lesions. We intend to gather a cohort of 100 patients diagnosed with combined endodontic and periodontal lesions, classifying them according to the suspected iatrogenic cause. Diagnostic methods, including imaging and clinical evaluations, will be employed to assess and document the findings.
