BACKGROUND/AIMS: Cross-country mountain biking and field hockey are two Olympic sports that pose a potential risk for dentofacial trauma. However, mouthguard use is not mandatory in either of these sports and knowledge about tooth rescue among athletes is often neglected. The aim of this cross-sectional epidemiological survey was to evaluate the prevalence of sports-related dentofacial injuries, mouthguard use, and attitudes regarding tooth rescue among cross-country mountain biking and field hockey athletes participating at pre-Olympic competitions held in Rio de Janeiro, Brazil.
A convenience sample of 217 athletes from 33 countries participating in cross-country mountain biking (n = 82; mean age = 30.96 ± 8.52 years) and field hockey (n = 135; mean age = 19.72 ± 2.46 years) pre-Olympic competitions were examined clinically, and they answered a questionnaire regarding previous history of sports-related dentofacial injuries, attitudes toward mouthguard use, and tooth rescue.
There were 120 (55.30%) males and 97 (44.70%) females who participated in the study. The prevalence of facial trauma was higher in mountain biking (54.88%) than in field hockey (26.66%, P < .001). Fracture was the most prevalent facial injury in mountain biking (80%), while laceration was the most prevalent in field hockey (30.55%). Extensive dental injuries occurred more often in mountain biking (47.37%) than in hockey (12.50%). The teeth most often affected were the maxillary central incisors in both mountain biking (57.89%) and field hockey (93.75%). Mouthguard use was more frequent among field hockey athletes (41.48%) than in mountain biking (1.22%, P < .001). The overall knowledge about tooth rescue was low, and most of the athletes in both sports did not know what to do in case of an avulsed tooth.
Prevalence of dentofacial injuries among XCO-MTB and field hockey athletes participating at this pre-Olympic event was high. The majority of the athletes in this study did not use mouthguards and were unaware of recommendations in the case of an avulsed tooth.
背景/目的：越野山地自行车和曲棍球是两项存在牙颌面外伤潜在风险的奥运项目。然而，这两项运动都不强制使用护齿器，而且运动员对牙齿救援的了解往往被忽视。本横断面流行病学调查的目的是评估参加在巴西里约热内卢举行的奥运前比赛的越野山地自行车和曲棍球运动员中，运动相关牙颌面损伤、护齿器使用和对牙齿救援的态度的流行率。
对参加越野山地自行车（n=82；平均年龄=30.96±8.52 岁）和曲棍球（n=135；平均年龄=19.72±2.46 岁）奥运前比赛的 33 个国家的 217 名运动员进行了临床检查，并对他们进行了问卷调查，内容包括运动相关牙颌面损伤的既往史、对护齿器使用的态度以及牙齿救援。
共有 120 名（55.30%）男性和 97 名（44.70%）女性参加了这项研究。面部创伤的患病率在山地自行车（54.88%）中高于曲棍球（26.66%，P<.001）。骨折是山地自行车中最常见的面部损伤（80%），而曲棍球中最常见的是撕裂伤（30.55%）。广泛的牙损伤在山地自行车（47.37%）中比在曲棍球（12.50%）中更常见。受伤最常见的牙齿是上颌中切牙，在山地自行车（57.89%）和曲棍球（93.75%）中均如此。护齿器的使用在曲棍球运动员中更为常见（41.48%），而在山地自行车运动员中则很少（1.22%，P<.001）。关于牙齿救援的总体知识水平较低，在这两项运动中，大多数运动员都不知道在牙齿脱落时该怎么办。
参加本次奥运前赛事的 XCO-MTB 和曲棍球运动员的牙颌面损伤发生率较高。本研究中的大多数运动员没有使用护齿器，也不知道在牙齿脱落时的建议。
