Dentsply Canada

The CDA/Dentsply Sirona Student Clinician Research Program provides an opportunity for one dental student from each accredited dental school in Canada to participate in a national clinical research competition.

Managed by the Canadian Dental Association (CDA) and sponsored by Dentsply Sirona International and Dentsply Sirona Canada (Dentsply Sirona), the program is held in conjunction with CDA's annual convention. The purpose of the program is to stimulate ideas, improve communication and most of all, increase student involvement in the advancement of the dental profession.

Method of Selection

Each year, CDA and Dentsply Sirona forward an Invitation to the deans of the 10 accredited dental schools in Canada. Each school may select one student to participate in the CDA/Dentsply Sirona Student Clinician Research Program. The selection is determined separately by each dental faculty. Students should contact their faculty for more information on how the selection process is conducted at their school.

The participating student clinician must be an undergraduate at the time of selection by his or her school. Dentsply Sirona provides funding for the qualifying students' airfare and travel expenses to the convention.

Judging of Clinics

Student clinicians provide a presentation (5 to 7 minutes) in one of two categories — 'clinical application and techniques' or 'basic science and research' — to a panel of qualified judges. Students must identify the purpose of the study, provide background information, outline how the study was conducted, and report on the results of the study and its possible significance.

Using established criteria, the judges evaluate the subject matter, oral presentation and visual presentation of each clinician. The judges then select a first and second prize winner among all competitors on a total point basis, regardless of category.


Following the program, CDA and Dentsply Sirona host a reception in honour of all student clinicians participating in the program. The winners are announced during the Awards Reception. Dentsply Sirona provides all awards and prizes. This year, the CDA/Dentsply Sirona Awards Ceremony will be held on Thursday evening.

The first prize is an expense-paid trip to the American Association for Dental Research (AADR) Annual Meeting, where the student clinician will make his or her winning presentation on a non-competitive basis, as part of the AADR's scientific program.

The second prize is $1000 cash. All participants receive a certificate of appreciation from CDA and Dentsply Sirona for their contribution to the table clinic program.

2018 Program

In 2018, the CDA/Dentsply Sirona Student Clinician Research Program will be held during the Canadian Dental Association (CDA) Convention hosted by the Dental Association of Prince Edward Island (DAPEI), at the PEI Convention Centre in Charlottetown, PEI, From August 22-25, 2018. The program features presentations by student clinicians from Canadian dental schools. Introduced in 1971, the CDA and Dentsply Sirona continue to work together to motivate and recognize hundreds of bright young minds to investigate new approaches to a wide range of oral health concerns.

The closed judging session will take place on the morning of Thursday, August 23. Convention attendees will have the opportunity to view the presentations and speak to the student clinicians during the open session on Thursday afternoon. The session room will be announced as soon as possible.

2018 Winners

The 2018 CDA / Dentsply Sirona Student Clinician Research Program was held during the Canadian Dental Association (CDA) Convention hosted by the Dental Association of Prince Edward Island (DAPEI), at the PEI Convention Centre in Charlottetown, Prince Edward Island. Here are the abstracts of the winning presentations.

First Prize

Factors affecting the degree of conversion of universal adhesives

Natalie Rosenthal (Manitoba 2019); Dr. Cristina Fiuza, Dr. Asmaa Haimeur (faculty collaborators); Dr. Rodrigo França (faculty advisor).

Natalie Rosenthal


Universal adhesives are advertised as having a simplified application technique, however all still require multiple steps. This study tested the effect of solvent evaporation, oxygen inhibition layer (OIL) formation, and curing time on the degree of conversion (DC) for the dental adhesives given the following acronyms: AB, PB, iBU, SBU, and OC.


Adhesives were rubbed onto a glass slide for 20 s, then air blown for 5 s or 40 s. Some samples had an Epitex strip (Anaerobic) placed over the adhesive before polymerization, while the other group of samples were cured without an Epitex strip (Aerobic). Samples were light cured for 10 s, 20 s, or 40 s (n=4). The DC was measured using Fourier transmission infrared spectroscopy (FTIR). Results were analysed with 3-way ANOVA and Tukey post-hoc test (α=0.05).


Curing under anaerobic conditions significantly increased the overall mean DC for all tested adhesives. A higher DC can be obtained by increasing solvent evaporation time for AB, iBU, SBU, and increasing curing time for all the adhesives, except iBU. Some universal adhesives benefit from a different application process than the manufacturers’ instructions.

Second Prize

Investigating Noise-Induced Hearing Loss in Dental Education and Dentistry

Kellie Zelmer (Dalhousie 2019), Dr. Cynthia Andrews (faculty advisor).

Kellie Zelmer


Noise-induced hearing loss (NIHL) can be an occupational hazard associated with the practice of dentistry. Unfortunately, this is not common knowledge among practicing dentists, nor is it taught in the vast majority of dental curricula. NIHL cannot be reversed, but it can be avoided if dental students and practicing dentists are properly educated on this topic.

At a dental school, with a recently renovated clinic, we questioned as to whether noise exposure is at a safe level and whether current dental students are aware of the potential risks associated with dental noise exposure.


Ethics approval was obtained to measure noise levels in a dental school educational setting and for the distribution of an online survey to dentistry students regarding their daily exposure to noise, self-reported experiences regarding their hearing, and awareness of NIHL. Survey data were analyzed using descriptive statistics for quantitative results and thematic analyses for qualitative results.


Noise levels in the new dental school practice settings were below 85 dB and are considered within safe limits.  However, approximately one third (28%) of dental students reported experiencing non-auditory effects such as an increase in anxiety, stress, frustration, irritation and/or difficulty focusing when operating due to the noise, and over half reported (52%) warning signs of hearing loss. There is a lack of knowledge about NIHL and dentistry with over half (55%) of students reporting being not aware. After completing the survey, the majority (80%) of students felt that their dental education should include the risks associated with NIHL in dentistry.
