Knowledge and attitudes of Arizona high-school coaches regarding oral-facial injuries and mouthguard use among athletes.

The authors assessed high-school athletic coaches' perceptions about oral-facial injuries and mouthguard use in sports that do not mandate mouthguard use. About 72 percent of the coaches said that their athletes sustained oral-facial injuries, 28 percent that some athletes used mouthguards regularly, 48 percent that athletes had sustained injuries and did not use mouthguards regularly, and 31 percent said they would not encourage mouthguard use. Advocacy for mouthguard use should focus on coaches, coaches' associations and rule-making organizations.
