  • Title: Orofacial and dental trauma of young children in Dunedin, New Zealand.
    Author: Chan YM, Williams S, Davidson LE, Drummond BK.
    Journal: Dent Traumatol; 2011 Jun; 27(3):199-202. PubMed ID: 21457187.
    Abstract:
    AIM:  The aims were to identify the predominant causes and types of orofacial injury in young children attending clinics at a University Dental School in Dunedin, New Zealand. MATERIAL AND METHODS:  A retrospective analysis of data from the records of all children aged 0-10years who had been seen for orofacial trauma in 1999 and 2000 was undertaken. RESULTS AND CONCLUSIONS: Three hundred traumatic incidents in 288 children were analysed; 86.6% had causes noted. In very young children, most injuries were because of falls, while collisions, falling and sports were responsible for more injuries in school-aged children. Playground equipment and ride-on vehicles played a role particularly in the older children. There were no incidents of trauma as a result of road traffic accidents. Ten injuries were caused by animals, mainly dogs. Location was recorded for two-thirds of accidents: the predominant place was at home, followed by school. No seasonal variation was apparent. There were 228 non-dental injuries, of which the majority were to the lips. The predominant dental injuries in both dentitions were concussions and subluxations with a significantly higher occurrence of both in the primary dentition (P<0.001). Upper central incisors were most often involved. The age distribution for boys and girls was similar. In conclusion, the causes and types of orofacial trauma in this group of young New Zealand school children attending a university dental school were similar to other studies, except for the high proportion of concussions recorded in both dentitions. While the injuries were well described, not all records noted the cause or location. This has resulted in changes to the standard recording form to provide consistency in data capture. Information from this study will also be used to support child injury prevention strategies in New Zealand.
