Mouthguards do more than just protecting teeth in youth ice hockey
Mouthguards were first developed in the 1890s by a British dentist to keep boxers from getting dental and facial injuries during matches. But there is another compelling reason to use this protection.
Researchers discovered that mouthguards reduce the risk of concussion in ice hockey, according to a new study by the 草莓污视频导航 published in the . 听
鈥淭his study is the strongest evidence to date that supports mandatory mouthguard use for youth between the ages of 11 and 17 when playing ice hockey,鈥 says Dr. Carolyn Emery, PhD, chair of the Sport Injury Prevention Research Centre at the Faculty of Kinesiology.
Though policy around the use of mouthguards is in place in some areas of Canada, researchers say it should be more effectively enforced.
鈥淚t can be challenging for referees to enforce the use of mouthguards, so we would like to see parents and coaches get involved to ensure they are being used as we saw a significant reduction in concussion with mouthguard use,鈥 says Dr. Brent Hagel, PhD, senior author on the study and a professor in the departments of Paediatrics and Community Health Sciences at the .听
Two styles of mouthguards tested
Researchers looked at players who sustained a concussion during play, and those who sustained an injury but did not have a concussion. They also looked at two types of mouthguards, those that were a dental custom fit, and those that were off-the-shelf.听
Both protected against concussion, reporting a 64-per-cent reduction in the odds of concussion when mouthguards were worn. However, this protection was statistically significant for off-the-shelf mouthguards and not the custom dental. Hagel noted it could be related to a smaller sample size once considering mouthguard type and that more work is needed in this area.
Mouthguards may protect against concussion because they reduce the forces transmitted to the brain, but further research is necessary to understand the protective mechanism.
鈥淎n off-the-shelf mouthguard is an inexpensive and effective way to protect against concussion, but we are in the early days of investigating the biomechanics of the specific types of the mouthguards that are best,鈥 says Hagel.听 鈥淭he main point is, we are on the right track for this piece of protective equipment, and this is something we want to investigate across multiple contact sports such as football.鈥

Importance of funded research by students
The study began as an undergraduate research project by 草莓污视频导航 Kinesiology student Dirk Chisholm, funded by Alberta Innovates 鈥 Health Solutions and the Markin Undergraduate Student Research Program for Health and Wellness.听
鈥淚t was thanks to Dirk Chisholm that this project came to be, as he was tenacious about getting it to the finish line,鈥 says Hagel.
Dirk Chisholm graduated with an undergraduate degree in Kinesiology from the 草莓污视频导航 and is now attending medical school at the University of Alberta.
鈥淭his exciting discovery is the final product of an undergraduate research project which demonstrates the value a strong undergraduate research program can have for our communities,鈥 says Emery.
The ) is a university-wide initiative to study concussion, which has brought together experts from the , Faculty of Kinesiology, and听, with support from the Alberta Children鈥檚 Hospital Research Institute () and the Hotchkiss Brain Institute (). The Alberta Children鈥檚 Hospital Foundation was instrumental in the creation of the ICRP and provides continuing support.
The research was funded by the Canadian Institutes of Health Research (Safe2Play), Alberta Innovates (Alberta Program in Youth Sport and Recreational Injury Prevention), and the Hotchkiss Brain Institute.
