Dentoalveolar trauma in Glasgow: an audit of mechanism and injury

Abstract

Traumatic dental injuries in children often require multiple follow-up visits to the dentist and may have long-term consequences for the developing dentition. The aim of this audit was to examine age, gender, location, time of year, mechanism of injury and type of injury sustained in relation to dentoalveolar trauma in children attending the paediatric dental trauma clinic at Glasgow Dental Hospital from 2002 to 2004, and to compare our findings with data in the published literature. Males suffered 60% of all dental trauma, 79% of sporting injuries and 85% of assaults. The injuries in males were more severe, representing 65% of enamel dentine and pulp fractures, 100% of crown root fractures and 66% of crown root and pulp fractures. A peak for trauma was seen in the 8–11-year-old group (43%). The majority of injuries in the under four age group resulted from falls (87%). Taken as a whole, falls accounted for 49%, sports related injuries 18%, bicycle and scooter 13%, assault 7%, and road traffic accidents 1.5% of all injuries. They also accounted for a far higher percentage of intrusive luxations (67%). The largest proportion of injuries occurred during the summer months (33%). Sixty-four percent of children suffered trauma to more than one tooth. Fifty-eight percent of injuries involved the dental hard tissues and pulp and the majority of these (82%) were crown fractures. Most subjects (82%) suffered trauma to their periodontal tissues, (26% concussion or subluxation, 26% lateral luxation and 23% avulsion). Injuries to the supporting bone were uncommon. Sixty-six percent of all injuries occurred outdoors. Our findings were similar to a number of published studies, but in contrast to several others. More consistency is required in the collection and reporting of trauma data to be able to draw meaningful conclusions by comparison.
