Abstract
Abstract— This study investigated anterior dental trauma presenting after‐hours in Newcastle and western Sydney. During the four‐year period 1983–1986, all patients presenting with anterior dental injuries to the Royal Newcastle Hospital (n = 382) or Westmead Hospital (n = 362) on week nights, weekends or public holidays were studied. In both areas, upper central incisors were the teeth injured most frequently. The mean numbers of teeth injured per patient were 1.9 at Newcastle and 2.0 at Westmead. The frequencies of injury types found in Newcastle and Westmead were similar. Luxations and avulsions accounted for 39.5 per cent of injuries at Newcastle and 39.6 per cent at Westmead. In Newcastle, the rate of occurrence of trauma was highest and relatively uniform in the 6–11, 12–17 and 18–23 year age groups. At Westmead, it was highest in the 6–11 year age group, followed closely by the 12–17 year age group. In both centres, the four main causes of trauma were falls, assaults and fights, sports and bicycle accidents. These accounted for 69 per cent of all injuries in Newcastle and for 69.4 per cent at Westmead. This study found a great similarity between Newcastle and western Sydney in relation to the predominant age and sex groups affected, causes of trauma, injury types and numbers and locations of injured teeth per patient. It is suggested that anterior dental trauma presenting after‐hours may be more severe, involve more teeth per patient and affect predominantly older age groups than is the situation during normal hours.
