  • Traumatic injury of tooth in children is commonly occurred problem. It is classified into tooth, periodontal tissue, supporting bone, soft tissue injury by it's area and extent. Among the periodontal tissue injuries, traumatically intruded teeth are common in anterior maxillary area, though the occurrence rate is rather low, the pulp and supporting tissue injury is possible by vertical impact. The treatment method of traumatically intruded teeth is various. Observation on the spontaneous reeruption for 3-4 weeks is recommended if the traumatized teeth are deciduous teeth or slightly intruded immature permanent anterior teeth. If this did not occur because the extent of intrusion is severe or the traumatized teeth are mature permanent anterior teeth, orthodontic traction is applied by fixed/removable appliances. At this time, light and continuous force is applied for the extrusive movement of the intruded teeth. When above procedures are impossible, surgical repositioning and fixation is recommended. In these cases, we performed conventional endodontic therapy for pulp necrosis and orthodontic traction with fixed appliance. We obtained satisfactory results and will report that.

  • Objectives : The purpose of this study was to investigate the knowledge of methods to deal with dental trauma in some middle school students. Methods : Among 375 middle school students, a total of 340 filled out the self-administered questionnaire (response rate of 90.7%). The data were analyzed statistically using chi-square analysis. Results : 32.9% of respondents received emergency care education of dental trauma. Knowledge by general information about dental trauma was not so different from the other questions. Tooth storage medium comprised 25.0% and 48.5% in milk and saline, respectively. Conclusions : In order to get the knowledge about emergency treatment of dental trauma in middle school students, it is necessary to develop the professional education program for middle school students.

  • There is a growing tendency for injury and it is essential to know about the epidemiology of the injured teeth for proper and timely treatment. Through empirical data analysis of 120 children who came to pediatric dentistry of Kangnung National University Dental Hospital, this study purposes to give an understanding about the injury and analyzes the frequency by children's sex and age, the number of injured teeth according to the area in the mouth, the types of injury, causes and places of injury, the frequency occurred by month and hour, the position of injured teeth, and the elapse of time. The main findings of this study are summarized as follows: 1. The frequency analysis by sex shows that the rate of boys is more likely to be higher than girls(1.6:1). 2. The frequency analysis by age shows that the ratio of children between aged 2~4 and 8~10 are high. 3. The number of injured teeth is generally one(51.7%). 4. Periodontal tissue injury is the main cause for the primary teeth. In case of permanent teeth, the ratio of hard tissue injury which is much increased than the case of the primary teeth, is similar to that of periodontal tissue injury. 5. The main cause of injury is fall for both dentition; In case of permanent dentition, the ratio of injury by sports is increased. 6. The place of injury for primary teeth is mainly home(38.8%); Street and school for permanent teeth(42.5% and 35%, respectively). 7. The frequency by month shows that the injury is most frequently occurred in July. 8. The frequency analysis by hour shows that injury for primary teeth mostly happens in the morning; in the afternoon for permanent teeth. 9. The position of injured teeth according to the area in the mouth is mainly maxilla anterior in both case of primary and permanent teeth and especially the ratio of central incisors is high, 10. More than half(59.2%) of patients came to the hospital within one day and the seriously injured were likely to come within one day than the slightly injured.

  • The aim of this study was to assess the outcome of MTA apexification in young permanent anterior teeth. Among the patients with the traumatized permanent incisors which were treated with MTA apexification, the dental records and radiographs were examined only for the patient who had follow-up examination at least 3 months after the treatment. Forty nine patients with 64 teeth were included in this study. Demographic information, location and type of teeth and periodontal injury, pre-treatment periapical lesion, clinical symptoms, status of MTA filling, healing of apical lesion and apical barrier formation after treatment were investigated. The outcome based on clinical and radiographic criteria were assessed. The results were as follows 1. Of 64 immature permanent incisors with MTA apexification, the clinical and radiographic success rates were 89.1% and 73.4%, respectively. 2. The maxillary incisors showed significantly higher success rates than the mandibular incisors. 3. There was no statistically significant difference in success rates among the teeth with different types of teeth and periodontal injury. 4. The status of MTA filling did not influence the clinical and radiographic success.

  • The loosely structured periodontal ligament and low mineralized bone surrounding erupting teeth provide minimal resistance to an extrusive force. The maxillary central incisors are the most frequently avulsed due to trauma. The prognosis of replanted teeth is affected by extra-alveolar period and conditions. Implant-supported restorations are contraindicated in adolescent patients with poor prognosis traumatized teeth. Autotransplantation of premolar to the anterior region provides a viable treatment alternative. This case report describes the autotransplantation of premolars and esthetic rehabilitation in a teenage patient with traumatized incisors, poor oral hygiene, and severe crowding. Comprehensive and long-term treatments were performed to improve complex and challenging oral problems.

  • Dilaceration is a tooth abnormaly occuring in the histo-morphodifferention stage resulting from disturbance between the uncalcified and already calcified portion that affects both the crown and root. The involved tooth is usually the maxillary central incisor and it also shows high prevalence of impaction. The cause of dilaceration can be either from the trauma of the primary tooth, ectopic development of the tooth germ or from cysts. And it is also found in some cases of Otodental syndrome, Hurler syndrome, Cleidocranial dysostosis. The purpose of this study is to show that periapical lesions caused by dental caries can be another factor in causing dilaceration.

  • 치아 외상은 크게 fracture와 luxation injury로 분류된다. 이 중에서 영구치의 root fracture는 외상의 0.5~0.7%를 차지하는 것으로 조사되고 있다. 호발부위로는 상악 중절치가, 나이로는 11~20세에서 호발하여, 이보다 어린 나이에서는 alveolar socket의 elasticity 때문에 fracture보다는 luxation 쪽으로 많이 발생하는 것으로 보고되고 있다.(중략)

  • Trauma from occlusion(TFO) is injury to the periodontal tissue as a result of occlusal forces. Mobility is a common clinical sign of occlusal trauma. In acute occlusal trauma, this may be accomanied by pain, tenderness to percussion, thermal sensitivity, and pathologic tooth migration. Chronic occlusal trauma may be marked by excessive wear and gingival recession. Radiographic finding include a widened periodontal ligament space, radiolucence and condensation of the alveolar bone and root resorption. TFO is related to the pathogenesis of periodontal disease. It can cause increased tooth mobility TFO itself does not initate or aggravate marginal gingivitis or initiate periodontal pockets. Active trauma can accelerate bone loss, pocket formation and gingival recession depending on the presence of local irritants and inflammation. Gingival recession associated with occlusal forces includes traumatic crescent, McCall's festoon and Stillman's cleft. TFO plays a minor role in the pathogenesis of early to moderate periodontitis. A 5-year-old male visited Yonsei University Pedodontics clinic with a chief complaint about gingival recession. Mobility, excessive wear, gingival recession were detected by clinical exam on the both mandibular deciduous ca nine. On the radiographic view, vertical alveolar bone loss was observed on both mandibular deciduous canine.
