DrBicuspid (8/2, Busch) reported that a study published in Dental Traumatology found significant deterioration in the fit of custom-made ethylene vinyl acetate mouthguards after one year of athletic use. Conducted by Dr. Tomoya Gonda and colleagues from the University of Osaka Graduate School of Dentistry, the study revealed a 48% increase in fit-checking material weight, indicating fit loss despite athletes reporting no change in comfort. The authors emphasized the need for objective fit assessments in sports dental care and suggested further research on mouthguard durability.
