In the ice-snow sports, the dental traumatology can be caused easily. This paper compares the differences in the clinical classification, the incidence and the severity of the dental traumatology in patients with or without sports mouthguard in the ice-snow sports. The results show that the most common teeth of the dental traumatology caused in the ice-snow sports are the upper central incisors. Without sports mouthguard, the avulsions (total luxation) are the most common (26.58%), followed by the subluxation (24.05%), the complicated crown-root fracture (13.92%) and the complicated crown fracture (10.13%). However, the simple crown fracture (36.84%), the concussion (21.05%) and the subluxation (15.79%) are common in the patients with sports mouthguard, and no avulsions are observed. This study suggests that with sports mouthguard the incidence and the severity of the dental traumatology can be reduced significantly, and the tooth loss can be avoided.
