Short Report


A perforation consists of a communication between the periodontium and the root canal space. This may result from caries or resorptive defects but most commonly occur iatrogenically. Fuss et al. reported that 10% of failed endodontic cases are due to perforations occurring during root canal therapy [1].

Iatrogenic root perforations (IRP) of the coronal third often result whilst attempting to locate and open canals or during careless post-space preparation. Perforations of the middle third may occur due to overzealous instrumentation (strip perforations) but also during the pursuit of sclerotic canals using ultrasonic instruments. By its turn, apical perforations frequently occur when the clinician does not fully respect the apical anatomy during mechanical root canal preparation [2].

According to Kvinnsland et al., 73% of all IRP occur in the maxilla, 53% during insertion of posts, whilst 47% occur during routine endodontic treatment. In maxillary anterior teeth, the...
