Abstract

A thorough knowledge of the root canal morphology and unusual anatomy of the tooth is critical for successful endodontic treatment. Common configuration in mandibular molar is two roots and three root canals with different combinations or curvatures. Instrument separation is one of the most common iatrogenic error that occurs in an endodontic practice. The treatment option and success vary based on a number of factors. These case reports are on the retrieval of the separated instrument from the coronal third of the middle mesial canal of the mandibular first molar and bypassing the instrument in the apical curvature of distobuccal root of maxillary second molar.
