The monoblock concept in endodontics

The ultimate challenge for successful endodontic therapy is to establish a homogenous unit of the root canals which requires a hermetic seal. Adhesion of root canal sealers to dentin is important to seal the root canal system thoroughly and to prevent microleakage. Bonding of root filling materials to the radicular dentin is known as ‘monoblocks' which has become more popular after introduction of bonding concept in the root canal system. The aim of this review highlights on newer materials and different concepts in rehabilitation of root canal space. Thus the potential of these monoblocks is discussed with the possibility of their application in endodontics in future.
