 note = {application/pdf, Clinicostatistical observation was made of trauma patients who had been examined at the (Outpatient Department) of Pedodontics of our college between January 1991 and April 1993. The following conclusions were obtained: 1) Sex ratio was 1.01: 1, i. e an almost equal number of male and female patients. 2) Injury by age-3～5-year-old infants (late stage of infancy) were most prevalent: infants below 6 years represented 60% of all patients, with overwhelming predominance of the low age-group. 3) Cause of injury-falling down followed by contusion were the main cause and effect of injury: the fact that generally, infants with immature mobility have a high tendency toward active conduct necessarily leads to a high incidence of contusion and falling down. 4) Site of injury-maxillary anterior teeth region was most frequently injured; also by age, 3～5-year-old infants (late stage of infancy) were injured in the above-mentioned region. 5) Mode of injury-perturbation and mucosal rupture were frequent; therefore, treatment at the first examination often included observation of the course, fixation, suture and the like.},
