File retrieval with sonics-A retreatment case report
Background: Instrument separation is one of the most stressful endodontic mishaps that can occur any time during the root canal treatment. Several techniques have been employed to facilitate instrument retrieval, however, they are technique sensitive, expensive and require great expertise. Aim: Through this paper, a conventional, yet convenient technique is suggested to retrieve the fractured segment with a combination of hand files and sonic agitation. Materials and method: A 35 year old patient presented with pain in lower anterior tooth. Clinical examination revealed an intact PFM (Porcelain fused to metal) crown with no soft tissue abnormality. A radio-visio-graph indicated a fractured H-file extending from the apical third to 2 mm beyond the radiographic apex with an associated radiolucency with respect to 31. Thus, a retreatment aimed at retrieval of the fractured instrument followed by obturation and post endo restoration was planned without removing the fixed prosthesis. Conclusion: It was possible to successfully remove broken file from the root canal using sonic agitation coupled with H files with minimal damage to radicular dentin.
