Cleaning and shaping the canal especially the apical third gives us a good result in root canal treatment. Any impediments in the canal like ledge formation or separated instrument hinders this procedure. Separated instrument as such will not have deleterious effect on the success but it all depends on the stage of root canal treatment at which the instrument gets separated. Many instrument retrieval kits and techniques have been mentioned in the literature. Some of these procedures might require unnecessary removal of root dentin which weakens the root structure. Here we present a case report where a separated lentulospiral was retrieved from disto–buccal canal of maxillary left second molar using a novel and indigenous method, a prototype of tube and glue method using chair side apparatus.
