Improving endodontic success through coronal leakage prevention — part 1

Dr. Gregori M. Kurtzman discusses a major determinant of endodontic success or failure Introduction Coronal leakage within the canal system following obturation has been associated with endodontic failure. The literature suggests this is more likely a determinant of clinical success or failure then apical leakage.1-3 Recent advances in obturation materials have shown to provide superior …

A clinical case of a necrotic UR6 associated with periapical periodontitis

Dr. John Rhodes demonstrates a methodical approach using reciprocating nickel-titanium instruments Curved and sclerosed canals can raise difficulties for the operator during root canal treatment resulting in iatrogenic errors. In this case, challenging root canal anatomy in a maxillary molar (UR6) was successfully negotiated using a methodical approach and reciprocating nickel-titanium instruments. Clinical examination A …
