Abstract

Background/Aim

Mouthguards are crucial for protecting athletes against orofacial injuries, yet concerns persist regarding their potential impact on oral functions. This study aimed to investigate the effects of sports mouthguards on oral functions and speech over time.

Material and Methods

Thirty national rugby players received custom-fitted mouthguards. Questionnaire responses and speech recordings were collected before mouthguard use and at various intervals after using mouthguards: immediately, 1 week, 2 month, and 6 months. Spectrographic analysis was performed to measure voice onset time (VOT) for /p, b, t, d/ phonemes. Questionnaire responses were assessed with Friedman's test, while VOT changes were examined using one-way repeated measure analysis of variance.

Results

Compliance with mouthguard use improved during training and competitions, with consistent wear reported during matches. Over time, speaking difficulties and lisping decreased significantly (p < .001). The perception of nausea improved (p < .001), stabilizing after 1 month (p = .414). Sensations of bulkiness declined (p < .001). Mouth dryness reduced steadily, with no occurrences reported by all players by the end of the study. None of the participants reported bad breath, ulcers, or redness in the mouth. VOT changed immediately after wearing mouthguards (p < .001), gradually regressing toward the baseline, although not completely reaching it. Players held a favorable view of mouthguard use, with comfort and support for mandatory use increasing over time.

Conclusions

Custom-fitted mouthguards do not lead to significant long-term disruptions in oral functions. Athletes generally adapt to mouthguard use, reporting improved comfort and greater support for their use.

使用定制护齿时口腔功能和言语的变化：一项前后对照研究。

背景/目的：运动护齿对于保护运动员免受口腔损伤至关重要，但人们对其对口腔功能的潜在影响一直存在担忧。本研究旨在调查运动护齿随着时间的推移对口腔功能和言语的影响：30 名国家橄榄球运动员接受了定制的护齿。在使用护齿前和使用护齿后的不同时间段（立即、1 周、2 个月和 6 个月），收集了调查问卷和语言记录。对/p、b、t、d/音素的发声时间（VOT）进行了光谱分析。问卷回答采用弗里德曼检验进行评估，VOT变化采用单向重复测量方差分析进行检验：结果：在训练和比赛期间，使用护齿的依从性有所提高，据报告，在比赛期间佩戴护齿的情况始终如一。随着时间的推移，说话困难和口齿不清的情况明显减少（P量身定制的护齿不会对口腔功能造成严重的长期影响。运动员一般都能适应护齿的使用，并表示其舒适度有所提高，使用起来也更有支撑力。
