There is continued speculation on the value of mouthguards (MGs) in preventing mild traumatic brain injury (MTBI)/concussion injuries. The purpose of this randomized prospective study was to compare the impact of pressure-laminated (LM), custom-made, properly fitted MGs to over-the-counter (OTC) MGs on the MTBI/concussion incidence in high school football athletes over a season of play. Four hundred twelve players from 6 high school football teams were included in the study. Twenty-four MTBI/concussion injuries (5.8%) were recorded. When examining the MTBI/concussion injury rate by MG type, there was a significant difference (P = 0.0423) with incidence rates of 3.6% and 8.3% in the LM MG and OTC MG groups, respectively.
关于口腔防护器（MGs）在预防轻度创伤性脑损伤（MTBI）/脑震荡损伤方面的价值，一直存在猜测。这项随机前瞻性研究的目的是比较压力层压（LM）定制且佩戴合适的MGs与非处方（OTC）MGs对高中橄榄球运动员在一个赛季比赛中MTBI/脑震荡发生率的影响。来自6支高中橄榄球队的412名球员参与了该研究。记录到24例MTBI/脑震荡损伤（5.8%）。按MG类型检查MTBI/脑震荡损伤率时，发现存在显著差异（P = 0.0423），LM MG组和OTC MG组的发生率分别为3.6%和8.3%。
