 note = {P(論文), For the prevention of sports injuries in the stomatognathic system, the use of mouthguards is strongly recommended in contact sports. The purpose of this study was to survey the incidence of sports injuries of the stomatognathic system and to investigate problems with the use of mouthguards in contact sports. Questionaires were sent to 474 university American football players in Hokkaido. There were 229 responses, and the results were as follows: 1. The rate of incidence of sports injuries was 19 percent ; and 70 precent of the injuries occured in the soft tissues and 18 percent were fractures of teeth. 2. Fifty two percent of the injuries occured during practice and 27 percent in games ; almost all injuries occured in tackle and block plays. 3. Ninty seven percent of the players were using commercially available mouthguards but only 34 percent of the players were always wearing mouthguards. Using mouthguards give rise to speaking difficulties, discomfort, and breathing difficulties, and most of the players would like to see improvements to the mouthguards. 4. The rate of incidence of injuries in the players who always wear mouthguards was 8 percent and most injuries occured in soft tissues. The rate of injuries in players who do not always wear monthguards was 25 percent and included more serious injuries. 5. The incidence of neck injuries was 17 percent and 9 percent reported concussions.},
