The aim of this study was to evaluate in vivo the clinical applicability of two electronic apex locators (EALs) - Apex (Septodont) and iPex (NSK) - in different groups of human teeth by using radiography. The working lengths (WLs) of 100 root canals were determined electronically. The EAL to be used first was chosen randomly and a K-file was inserted into the root canal until the EAL display in...

To the editor: We thank Dr. Sabour for his comments about our article on reliability of two different presurgical preparation methods for implant dentistry based on panoramic radiography and cone-beam computed tomography in cadavers. We appreciate valuable comments from your profound knowledge and numerous research experiences to you. We agree that it would have been better if agreement in one ...

PURPOSE The purpose of this study was to evaluate the hypothesis that early motion increases tibial tunnel enlargement in patients who underwent anterior cruciate ligament (ACL) replacement with hamstring autograft. TYPE OF STUDY Cohort analytic study. METHODS All patients in this study had received a doubled semitendinous and gracilis graft. Grafts were secured in place with an implant-fre...

The mesiobuccal root of the maxillary first molar has generated more research and clinical investigation than any other root. An inability to detect and treat a second mesiobuccal canal (MB2) is a reason for endodontic failure in maxillary first molars (1). Modifications in endodontic access and detection techniques, along with advancements in illumination and magnification technology, have aid...
