Drs. David Keinan, Aviv Shmuel, Shlomi Ritz, and Iris Slutzky-Goldberg study the effects of the presence of chloroform in the canal during retreatment Abstract Objectives The aim of the study was to evaluate the accuracy of the Apex NRGXFR and Apit 11 electronic apex locators (EALs) in the presence of chloroform during endodontic retreatment ex …

Dr. Gregori M. Kurtzman continues his discussion of coronal leakage prevention Introduction As discussed in part 1, coronal leakage is a frequent cause of endodontic failure related to salivary bacteria percolating between the coronal aspect of the tooth, down the obturated canals to lead to apical reinfection. This can be prevented by how the tooth …

Drs. Yurii Riznyk and Svitlana Riznyk present a challenging case demonstrating the importance of locating all root canals A 30-year-old female patient presented with symptomatic irreversible pulpitis of both LR6 and LL6 teeth. Cone beam computed tomography (CBCT) of the region revealed a middle mesial canal (MMC) in tooth LR6, and a middle distal canal …

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 …

Dr. John Rhodes presents another interactive, practical, and problem-solving solution in endodontics. In this issue, he looks at the identification, diagnosis, and management of cracked teeth The survival rate of root-filled teeth at 5 years can be as high as 99%, but presence of a crack could reduce the likely survival rate by up to …

Dr. Jason Bedford shows how a new hydroxyapatite root repair material benefits the apical closure and healing of a large periradicular radiolucency Introduction Traumatic injuries to the upper central incisors are extremely common. By the age of 20, 23% of males and 13% of females have suffered some degree of traumatic injury to their anterior …
