Background/aim: Participation in sports activities is a source of dental injury. Despite recommendations for the use of mouthguards, athletes underutilize them. The aim of this study was to provide estimates of dental injuries, the mechanism of injuries and the utilization of mouthguards in high school sports.
Materials and methods: This study was a secondary analysis of an existing dataset of a convenience sample of the National High School Sports-Related Injury Surveillance Study. Data of athletic exposures, dental injuries, mouthguard usage, and mechanism of injury from the 2005/2006 to the 2019/2020 academic years were analyzed.
Results: During the study period, there were 459 dental injuries in 49,987,927 athletic exposures resulting in a dental injury rate of 0.9 per 100,000 athletic exposures (AE). Slightly more than half of the traumatic dental injuries were sustained during competition (n = 256; 55.8%) and the rest (n = 200; 43.6%) were sustained during practice. The rate of dental injury in competition was 3.6 times higher than the rate in practice (RR: 3.6, 95% CI: 3.0-4.4). Dental injuries comprised 0.4% of the total 108,574 injuries sustained by athletes. Among girls' sports, field hockey had the highest rate (3.5 per 100,000 AE) and among boys' sports, basketball (2.4 per 100,000 AE) had the highest rate of dental injury. The most common mechanism of injury was contact with another player (276; 60.4%) followed by contact with apparatus (146; 31.9%). In the majority of dental injuries (308; 75.1%), the athlete was not wearing a mouthguard when the dental injury was sustained.
Conclusions: Dental injuries were a small proportion of all injuries sustained by high school athletes. The majority of dental injuries were sustained when the athlete was not wearing a mouthguard.
