UBC Graduate Prosthodontics Student Wins ACP Award Graduate prosthodontics student Dr. Nesrine Mostafa’s poster garnered a second-place win from the American College of Prosthodontists (ACP). The competition was held in Orlando, Florida, during the College’s 45th Annual Session, October 22 to 24, 2015.

There were 126 posters in the ACP competition, with three UBC students entering. “We are very proud of Nesrine and her novel research,” says Dr. Chis Wyatt, director of UBC’s graduate prosthodontics program, and Mostafa’s graduate supervisor. Mostafa is in her third and final year at UBC, completing a Master of Science in Craniofacial Science combined with a diploma in Prosthodontics. Mostafa’s poster, “Marginal Fit of Conventional and Digital Lithium Disilicate Crowns: An In-Vitro Cross-Sectional Analysis,” presents her study that systematically assessed and compared the marginal fit of crowns fabricated using digital technology versus crowns obtained using a conventional (lab) approach. This is one of the first studies to assess the marginal fit of ceramic crowns using microcomputed tomography and a systematic 2D and 3D analysis. Her coresearchers included Wyatt and UBC Dentistry faculty members Drs. N. Dorin Ruse and Ricardo M. Carvalho (Department of Oral & Biological Sciences) and Nancy Ford (director,

Centre for High-Throughput Phenogenomics). “In our study, digitally fabricated crowns showed better fit as compared to conventionally fabricated crowns,” she notes. “Although there are several types of crowns, ceramics—tooth-coloured crowns—are the most aesthetically accepted to restore compromised teeth,” Mostafa explains. “Traditionally, these crowns are fabricated in the lab and require multiple procedures; therefore, they are prone to errors.” To overcome limitations, this study used digital technology for crown fabrication; that is, incorporated a camera, computer and milling machine to carve crowns from ceramic blocks. Generally, the clinical success of crowns is dependent on their precise fit to the teeth. Crowns that do not have an intimate fit to the tooth have marginal gaps that can collect plaque, resulting in subsequent development of dental caries (tooth decay), gingivitis (gum inflammation) and periodontitis (bone loss). Winning selections in the American College of Prosthodontists poster competition are based on a combination of factors, including the quality of research, how it is presented by the student during the poster session, and the knowledge of the student about the research topic.
The Canadian Academy of Health Sciences (CAHS) bestowed Fellowship on Dr. Michael I. MacEntee, professor emeritus of Prosthodontics and Dental Geriatrics, at its Forum and Annual General Meeting held in Ottawa on September 17, 2015. CAHS provides timely, informed and unbiased assessments of urgent issues affecting the health of Canadians. CAHS Fellows are those who have a history of outstanding performance in the academic health sciences in Canada. Attaining Fellowship is a substantial honour to the Faculty of Dentistry. MacEntee, who recently retired, focused his teaching and research on access of oral health care for vulnerable populations, and especially for people who are old and frail. He has published numerous books, chapters and peer-reviewed papers on this and related subjects, and currently he is the editor-in-chief of Gerodontology: The International Journal of Dental Geriatrics. He is a past president of both the Royal College of Dentists of Canada and the International College of Prosthodontists. In 2009, he received a Distinguished Scientist Award from the International Association for Dental Research and a Killam Teaching Prize. In his retirement he continues with his research and writing. There are only six dentists who are CAHS Fellows: From UBC, MacEntee joins Dr. Chris Overall, professor and Canada Research Chair in Metalloproteinase Proteomics and Systems Biology. There are also two CAHS Fellows from each of McGill University and the University of Toronto.
