- CrossFit® is a popular training method aimed at improving physical fitness, but there's limited research on bruxism (teeth grinding/clenching) among its practitioners, despite previous suggestions of increased clenching during weightlifting.
- The study examined bruxism signs in 57 CrossFit® practitioners, using various questionnaires and assessments to gather data on oral behaviors and related health metrics.
- Findings showed a high prevalence of teeth clenching (61.4%) and dental issues like tooth wear and lesions, but no clear link was established between bruxism signs and the intensity of physical activity, highlighting the need for dental health education in CrossFit® communities.
