Nic Pettit served a two-year LDS mission in Italy and completed his degree in Italian with a minor in chemistry at Brigham Young University in Provo, Utah. He then earned his DMD from Roseman University in 2016.

Dr. Pettit has a particular research interest in the use of bioceramic sealers in obturation of endodontic therapy. He is also interested in exploring techniques for diagnosis of dentinal defects of the root canal system.

Current research project: The Outcome of Nonsurgical Endodontic Treatment: A Retrospective Evaluation of Endodontic Treatment Performed by Dental Students Using the BioRaCe Rotary File System and EndoSequence BC Sealer with EndoSequence BC Points.

 

Elisasvarthvit-183x244

Elísa Kristín Arnasdóttir received her DDS education and training at the School of Dentistry at the University of Iceland in 2011. She worked in Akureyri, Siglufjorour and Olafsfjorour for five years as a general dentist. She did a research project about a new scoring index for dental erosion and published an article related to that.

Her interests in research are related to endodontic diagnosis and outcomes, common trends in endodontic practices in Iceland versus North Carolina, and periapical microsurgery.

Krista H. Andersen attended Clemson University in S.C., where she completed her bachelor’s degree in biological science. She then moved to Charleston, S.C. to attend dental school at the Medical University of South Carolina. She is currently a second-year endodontic resident. Her masters thesis focuses on the long term outcome of different endodontic materials and potential influencing prognostic factors.

 

 

shallal.ayzin

Mark Shallal-Ayzin is a 2014 graduate of the University of Michigan School of Dentistry. He obtained his bachelor’s degree at University of Michigan in exercise physiology. While in dental school, Mark went on various mission trips to Kenya and Jamaica and has an interest in access to care in underserved communities.

He has developed an interest in research on teeth with carious exposures of the pulp and how to save them. He believes that an endodontist should not only be concerned with saving teeth that have undergone necrosis but also the prevention of said necrosis.

Current research project: Vital Pulp Therapy on Permanent Teeth with Mature Apices.

 

 

trinh

Tam M. Trinh received his Bachelor of Science degree in biology from the University of Illinois at Chicago in 2008, and later earned his DDS degree from the University of Illinois at Chicago in 2012. Following his graduation from dental school, he practiced dentistry in Chicago for two years before enrolling at UNC to pursue endodontics.

His research interests include vital pulp therapy, and 3-D printing and CBCT.
