Iatrogenic Perforation
Pronunciation: eye-AT-roh-JEN-ik
An unintended communication between the root canal system and the periodontal or periradicular tissues caused by a clinical instrument or procedure, detectable radiographically as an alteration in expected root morphology or as periradicular bone loss.
Full Definition
Iatrogenic perforation in the context of dental radiology refers to a treatment-induced breach in the root structure or pulp chamber floor that connects the root canal to the periodontium. Radiographically, perforations may be visible as a sudden change in root canal direction, a strip of radiolucency along the lateral root surface, or associated periradicular bone loss if infection has supervened. Reporting dentists and editors must distinguish iatrogenic perforation (caused by treatment) from resorptive perforations or developmental grooves. The term 'iatrogenic' is an important qualifier in radiological reports and medicolegal documents; editors should ensure it is not omitted when the aetiology is treatment-related.
Usage
Usage note: Always include 'iatrogenic' as a qualifier when the perforation is treatment-induced, as this has medicolegal implications. Do not abbreviate in formal reports. Distinguish from resorptive perforation in report language.
In Context
- "Periapical radiography revealed a lateral radiolucency at the mid-root level of tooth 45 consistent with iatrogenic perforation during previous root canal treatment." — Periapical radiograph report
- "The clinical notes referenced 'perforation' without the qualifier 'iatrogenic'; the editor flagged this as ambiguous for medicolegal purposes." — Clinical record audit
