Surgical Management of a Separated Endodontic Instrument using Second Generation Platelet Concentrate and Hydroxyapatite.

Fractured endodontic instrument is an unfortunate endodontic mishap which may obstruct thorough cleaning and shaping of the root canals with potential impact on the endodontic prognosis and treatment outcome. When the fractured segment lies apical to canal curvature, overzealous removal of tooth structure is required to gain access to the separated segment which in turn increases the likelihood of root fracture. In infected cases, the stage at which instrument separation occurs is crucial as root canal disinfection is jeopardized.
