Position Statement and Recommendations for Custom-Made Sport Mouthguards.

Sports-related traumatic dental injuries (TDIs) are a significant global concern, particularly in contact sports, where the risk of orofacial injuries is high. Custom-made sports mouthguards (CSMs) are recognized as the most effective means of preventing these injuries, providing both protection and comfort without impairing athletic performance. Despite their proven benefits, there is no globally standardized approach to mouthguard design, fabrication, or usage, primarily due to varying regulations, awareness levels, and cultural attitudes toward sports safety across different countries.

Effect of laser irradiation during in-office tooth bleaching on surface properties of resin-based restorative materials.
