Abstract : Endodontic procedural errors in a curved canal make it difficult to negotiate the original canal due to the straight access. A deviation from the original canal curvature without communication with the periodontal ligament during root canal treatment is termed ledge formation.

 The type of canal was found to have an effect on the incidence of ledging. The mesiobuccal, mesiolingual and canals of molars exhibited a significantly higher incidence than the distal and palatal canals. This report presents a case of a ledged mesiobuccal canal in a maxillary molar using modified conventional method to bypass and remove it.
