Dental trauma in children and young adults visiting a University Dental Clinic

The aim of the study was to present the distribution of traumatic dental injuries in the permanent anterior teeth in 447 consecutively selected patients in the age interval of 6 to 25 years treated at the Department of Paediatric Dentistry at the University Dental Clinic in Rijeka, Croatia, in the period from 2001 to 2006. Data on age, gender, number of injured teeth and type of injury were taken from the dental records. Of all 447 consecutively selected patients with traumatic dental injury 56.2% were boys and 43.8% were girls with a male/female ratio 1.28:1 (P < 0.01). The highest frequency of tooth injuries occurred among 10- to 13-years-old children. Among 30.6% of the cases, two or more teeth were injured (38.6% in boys and 21.4% in girls). Traumatic injuries affecting teeth in the upper jaw were more frequent (P < 0.001). The most commonly affected teeth were the maxillary central incisors (42.4% of right central incisors and 38% of left central incisors). The most frequent injury was enamel and dentin fracture without pulpal involvement (38.7%). In conclusion, more attention should be paid to preventive measures.
