Abstract
Traumatized teeth may concurrently suffer damage to the hard tissue, periodontal tissue and pulp. Recent statistics from several countries show that 15-23% of 12-year-olds have suffered trauma to the permanent dentition.
Long-term clinical investigations as well as experimental studies on various aspects of dental traumatology have been instrumental to the revision of the guideline on treating traumatic dental injuries. The complications peculiar to dental injuries are circulatory disturbance, tooth crack (incomplete fracture), pulp canal obliteration, internal resorption, and external root resorption. Follow-up and mouth guards are effective for maintaining the long-term functions of traumatized teeth.
