The purpose of this study was to examine factors hindering the use of mouthguards and the incidence of orofacial injury among young male rugby players. 69 high school rugby players (Group 1) and 431 medical student rugby players (Group 2) participated in this study. Participants in Group 1 used custom-made mouthguards fabricated according to a standardized method, whereas participants in Group 2 used custom-made or over-the-counter mouthguards of their choice. The factors associated with orofacial injury were assessed by logistic regression analysis, while factors hindering mouthguard use were assessed by multinomial logistic regression analysis. All data were obtained from a questionnaire developed by the Japanese Academy of Sports Dentistry. We found that breathing problems were the main factor contributing to the reduced frequency of mouthguard use. In both groups, a significant negative association was observed between the frequency of mouthguard use and the risk of orofacial injury. The group using standardized custom-made mouthguards reported fewer complaints about breathing problems and a higher frequency of mouthguard use. The results of this study suggest that increasing the frequency of mouthguard use would reduce the risk of orofacial injury among young male rugby players. We also conclude that users of custom-made mouthguards complain less frequently of breathing difficulties.
本研究的目的是调查阻碍护齿器使用的因素以及年轻男性橄榄球运动员口腔面部损伤的发生率。69名高中橄榄球运动员（第1组）和431名医科学生橄榄球运动员（第2组）参与了本研究。第1组参与者使用根据标准化方法制作的定制护齿器，而第2组参与者使用他们选择的定制或非处方护齿器。通过逻辑回归分析评估与口腔面部损伤相关的因素，同时通过多项逻辑回归分析评估阻碍护齿器使用的因素。所有数据均来自日本体育牙科学会编制的问卷。我们发现呼吸问题是导致护齿器使用频率降低的主要因素。在两组中，护齿器使用频率与口腔面部损伤风险之间均观察到显著的负相关。使用标准化定制护齿器的组报告的呼吸问题较少，护齿器使用频率较高。本研究结果表明，增加护齿器的使用频率将降低年轻男性橄榄球运动员口腔面部损伤的风险。我们还得出结论，定制护齿器的使用者呼吸困难的抱怨较少。
