PR15 - Assessing the Root Morphology Around the Middle Mesial Canal in Mandibular First Molars Using Cone Beam Computed Tomography

Thursday, April 26
10:00 AM - 1:00 PM
Room: Exhibit Hall

The middle mesial canal (MMC) in mandibular first molars has been clinically identified with a prevalence up to 37.5%.  The mesial root morphology of mandibular first molars describes a deep concavity in its distal aspect 2 milimeters apical to the furcation (danger zone), where the risk of strip perforation or root perforation is increased. The study will assess the correlation between the presence of a MMC and the distance between the mesio-buccal (MB) and mesio-lingual canal (ML) at the pulpal floor level. It will also evaluate the correlation between the presence of a MMC and the distance between the MMC and the external root surface in the danger zone. We will conduct morphological measurements of mandibular first molars using a data set of CBCT studies taken between September 2016 to September 2017 in the Department of Endodontics at NYU College of Dentistry. A preliminary data of 20 cases showed that the average distance between MB and ML canal when there is a MMC is 3.61 mm, while when there is no detectable MMC, it is 2.69 mm (p=0.02). The average distance to the danger zone area when there is MMC is 1.28 mm, while when there is no MMC, is 1.08 mm (p=0.04). There appears to be a correlation between presence of a MMC, the distance between ML and MB orifice, and thickness dentin in the danger zone. We will be collecting more data and look forward to presenting our analysis at the upcoming AAE meeting. 

Frederic Elbaz

Endodontic Resident
New York University College of Dentistry

Frederic Elbaz completed his DMD at Université de Montréal in 2014. He then completed a General Practice Residency in New York City at The Mount Sinai Hospital, which sparked his interest in endodontics. Following his residency, Frederic returned to his hometown of Montreal, where he worked as an associate general dentist for two years, performing as many endodontic procedures as possible. However, this did not quench his thirst for the understanding of the endodontic science. He then began an endodontic specialty program at NYU School of Dentistry. He is currently flourishing in his first year of the program.

Riyadh Alroomy

Endodontic Resident
New York University College of Dentistry

Dr. Riyadh M. Alroomy is a second year endodontic resident at NYU college of Dentistry. He received his BDS Degree in 2011 followed by a one-year internship program from King Saud University, College of Dentistry, Saudi Arabia. After that he worked as a teaching assistant in the endodontic department at Almajmaah University, College of Dentistry, Saudi Arabia. He completed a one-year fellowship in endodontics for international dentists in NYU College of Dentistry. Then, he joined a Master of clinical research program in NYU College of Dentistry (in progress). Currently, Dr. Alroomy’s research focus is in chronic endodontic pain, anxiety effect in endodontic and rare teeth morphology.
