The dental avulsion is the expulsion of an integral tooth for a traumatic cause such as the fall of a bicycle, a stumble, the practice of a contact sport (rugby, basketball, football, etc.) without the use of mouth guard or blows to the height of the base of the nose caused by games, accidents.
Dental avulsion can occur in both temporary teeth and permanent teeth. The difference is the treatment, since the temporary or deciduous teeth are not reimplanted.
The teeth most commonly avulsed in both dentitions, the temporary and the permanent, are the maxillary central incisors; and the most affected age group is usually between 7 and 11 years old. Men had an incidence of avulsions three times greater than women.
