title: Dental trauma prevention with mouthguard in a nose fracturing blow to the face: Case report.
abstract: Orofacial injuries are common in sports activities and may vary in complexity and the tissues involved. Most sports-related trauma occurs when a player hits another player, an object or the ground. This report presents a case of an injury caused by a punchlike blow to the face during a handball college team practice session. The patient suffered a traumatic blow to the left side of the nose and mouth and promptly attended a dentist. After a clinical examination and a CBCT scan, the following injuries were diagnosed: upper lip laceration, upper left lateral incisor subluxation and anterior nasal spine fracture. More severe teeth injuries were likely prevented because the patient was wearing a mouthguard.
