abstract = {The players in the 85th Japan High School Rugby Football Tournament were required to wear a mouthguard following enactment of a domestic law for the game in Japan in December 2005. In this article, we report the results of the questionnaire survey to the players. The all players according to the survey the 79.8% of the players had already worn a mouthguard before the enactment of the law. On the contrary, the all players ware a mouthguard in this tournament. In the investigation of the same tournament 9 years ago, the prevalence of wearing a mouthguard was 44.4%. Mouthguards have now become very popular for high school players in Japan. Tooth injuries were reported in 34 players (2.7%) compared with in 81 players (6.4%) 9 years ago. 75.7% of the players had their mouthguards custom-made at a dental office. The International Rugby Board (IRB) recommends the use of a mouthguard to protect against not only injuries of the teeth but also concussion. The IRB asks players to wear a mouthguard that has been properly designed and fabricated. We propose that mouthguards should be made according to standards for the materials, design, and fabrication.
