Sports dentistry is the branch of sports medicine dealing with prevention and treatment of dental injuries and oral diseases associated with sports and exercise. Amateur and young athletes face greater risk of oral injuries, because they may not receive proper guidance and/or training. Although the indication of customized types of mouthguards has increased, and the effectiveness for preventing injuries has been demonstrated, there is a need to further specify the sport characteristic, age group, selected material, guard design, as well as time of use.
