PR47 - Ex-Vivo Analysis of BioCeramic Sealer in the Apical Area From Failed Non-Surgical Root Canal Treatment and Analysis of EndoSequence Putty From Failed Surgical Re-Treatment: Case Series

Thursday, April 26

Room: Exhibit Hall

Introduction: The purpose of this study was to investigate the depths of penetration of silicate sealer and putty: EndoSequence® BC Sealer and EndoSequence® Root Repair Material Putty (Brasseler, USA) in the dentinal tubules. This study also evaluated the final composition of the set material. Method: Samples were taken from teeth, which were originally obturated with EndoSequence® BC Sealer and gutta-percha by endodontic residents, and then underwent surgical re-treatment, where the apical 2-3 mm were resected and placed in formalin (n=2). Also, failed teeth that were previously treated with surgical re-treatment, with a retro-preparation and filled with BC Putty, which were later extracted two to 10 months after surgical re-treatment, were then placed in formalin (n=5). Samples were then placed in 17% EDTA for 10 minutes and 4% NaOCl for 10 minutes prior to evaluation. The dentinal tubule penetration was examined under SEM and the elemental composition was analyzed with Energy Dispersive Spectroscopy (EDS). Results: From the EDS analysis, the presence of silicon in EndoSequence® BC Sealer/BC Putty was the only difference noticed between the set material and tooth structure. BC Sealer penetration was minimally present in the apical area. No tags to the tooth structure was seen with BC Putty.

Dr. Karabucak is Chair, Associate Professor of Endodontics, and Director of the Postdoctoral Endodontics Program. He is involved with endodontic courses/seminars in pre- and postdoctoral programs. He also runs selective microscope training courses for predoctoral students.

After earning his dental degree from Istanbul University School of Dental Medicine in 1993, Dr. Karabucak completed his endodontic postgraduate training at the Department of Endodontics at Penn Dental Medicine in 1998, where he also received his Masters in Oral Biology in 2002. He also earned his DMD degree from Penn Dental Medicine in 2002. His research interests include the cellular mechanisms of vasodilation and the inflammatory mediators in the dental pulp.

Dr. Karabucak has been the attending endodontist at the Children’s Hospital of Philadelphia since 2005 and is a Diplomate of the American Board of Endodontics. Additionally, he has lectured at national and international conferences and also serves as a reviewer for the Journal of Endodontics.
