Abstract

A clinical statistical study on 180 traumatized teeth of children between 1974-1983 was conducted in the Pedodontic Department, Gifu College of Dentistry.
The subjects comprised 100 children (0-15 yrs of age). The reports served as a basis for analyzing the age, sex and monthly distribution, location, the number and type of injuries and its treatment, causes for the trauma and the time elapse from the time of injury to the initial treatment.
The results were as follows;
1. The most frequent incidence of injuries was found in the children between 1-2 years of age, and the rate of incidence was 39.0% of all affected teeth. Boys suffered almost 1.7 times as many injuries as girls did. The injuries occured more frequently during April to May and October to November.
2. Dental injuries usually affected 1 to 3 teeth, and maxillary central incisors were most frequently affected both primary and permanent dentition.
3. Crown fracture and luxation, including subluxation exarticulation, were the most common type of dental trauma. The choise of the treatment for the injured primary teeth in order was immediate extraction, observation, pulp treatment and placement of splinting. For the permanent dentition, pulp treatment, placement of splinting, replantation and extraction were preferred.
4. The main causes for trauma were by collision and by falling.
5. Most children with the dental injuries visited the dental clinic for emergency care within serveral hours after injury or else on the day after.
