abstract="Dental trauma is for people under 25 years of age a larger threat than caries and periodontal diseases. Protrusion of the upper front teeth in youth should therefore be corrected by orthodontic treatment. By doing contact-sports the use of the mouth guard is necessary. Since several different types are available, one has to make a correct choice specified by the kind of sport. The statement that it is more important to use an apparatus than just to own it sounds logically, but is often not followed in daily live.<p /><p>Language: nl</p>",
