The objective of this study is to assess the appearance of dental injuries and the mode of treating children.
We conducted a survey of 255 children who visited the Pedodontics Clinic of Iwate Medical University with the chief complaint of dental injury. The patients were divided into four divisions according to the type of injury on deciduous teeth, permanent teeth, soft tissues or others.
The results were as follows:
1.The highest incidence of dental injuries was found in deciduous teeth.
2.Boys were more traumatized than girls with a 2:1ratio.
3.The more frequently injured positions appeared on the maxillary deciduous central incisors and maxillary permanent central incisors.
4.Dental injuries occurred most frequently at 1 and 2 years of age on deciduous teeth and at 8 years on permanent teeth.
5.The most common dental injury was subluxation on deciduous teeth and fructure of the crown on permanent teeth.
6.The average number of injuries per child was 1 tooth.
7.Most of the patients with injuries on the deciduous teeth and soft tissues visited the dental clinic on the day after the accident. The same number of patients with injuries on permanent teeth visited the clinic on the same day or the day after.
8.Reposition and fixation treatments were made in most cases of subluxation, but root canal treatment was further made on half of these cases.
9.Without regard to the degree of looseness, the root canal treatment was made on one-third of the deciduous teeth cases, while on loose permanent teeth, the same treatment was made on only 13% of the cases.
10.Over all, considering the treatments, damage to the pulp was greater in deciduous teeth than permanent teeth. Therefore follow up observations are very important for every stage of all injuries on deciduous teeth.
11.Discoloration of traumatized deciduous teeth occurred 1 month after injury. As the discolored teeth are often non vital, this fact may be useful for clinical evaluation.
