Coronal seal in endodontics

A plethora of patients undergo root canal procedures on a day to day basis. The drop out from the treatment protocols is even higher due to patient and/or doctor incompliance or even failure of treatment. This results in patients referring themselves elsewhere with symptoms due to incomplete treatment. In most of the cases it is noticed that the failure is associated with faulty coronal seal. The fault in the coronal seal may be due to varied reasons like infection of the prepared canals, fracture of restorations between appointments, doctor induced perforations and patient defiance. This review revolves around the root canal and its microflora and its cleaning and shaping protocols along with the comparative evaluation of coronal seal materials for the intended purpose.
