본 연구는 유치열에서 발생하는 함입성 손상의 특징을 조사하고 장기간의 추적 조사 기간 동안의 유치열 및 영구치열에 발생하는 합병증에 영향을 미칠 수 있는 요인을 평가하고자 하였다. 이를 위해 총 61명의 84개의 치아가 연구대상으로 선정되어 환자의 연령, 성별, 외상의 원인과 발생장소, 외상 치아의 손상 정도, 외상 발생 시 동반된 다른 손상, 치료방법, 추적조사 기간 중 유치열과 영구치열에 발생한 합병증이 조사되었다. 연령, 외상 치아의 손상 정도, 외상 발생 시 동반된 다른 손상의 종류가 유치 및 영구치의 예후에 미치는 영향을 확인하기 위해 조사된 자료는 카이제곱 검정과 Fisher의 정확검정으로 평가하였다. 유전치의 함입은 남아에게 여아보다 우세하게 나타났으며, 함입의 원인으로는 낙상의 빈도가 가장 높았다. 유전치의 함입은 집에서 가장 많이 발생했으며, 상악 유중절치에서 가장 많이 발생했다. 유치열에 발생한 함입의 중증도는 영구치열에 발생하는 후유증의 발생에 유의하게 영향을 미쳤다(p = 0.014). 유치의 함입성 손상에 연조직 손상이 동반된 경우, 다른 치주조직 손상이 동반된 경우 보다 합병증의 발생이 유의하게 적었다(p = 0.000).

The purpose of this study was to investigate the characteristics of intrusion in primary dentition and to evaluate factors influencing complications of primary and permanent dentition during long-term follow-up period. 61 patients (84 teeth) were selected in this study. Medical records of 61 patients were reviewed and age, gender, cause of injury, site of injury, severity of traumatic injury, other injuries associated with trauma, treatment method, and complications of primary and permanent dentition were examined. Collected data were statistically evaluated using Chi-square test and Fisher's exact test. Intrusion in primary anterior teeth was predominant in boys over girls and fall was the most common cause of trauma. It was most common at home and occurred most in the primary maxillary central incisors. Severity had an effect on the incidence of sequelae in permanent successors (p = 0.014). The incidence of complications was significantly lower in patients with soft tissue injuries than in patients with other periodontal injuries (p = 0.000).

The purpose of this study was to investigate characteristics of primary tooth intrusion and to evaluate factors influencing prognosis of primary and permanent dentition during the long-time follow-up period.
제안 방법
, Chicago, IL, USA). In order to determine the factors that affect prognosis, age, severity and type of accompanied injury were examined statistically. As the number of teeth which were followed-up until their successors erupt was small, influence of age and severity on prognosis of permanent tooth was statistically analyzed using Fisher’s exact test.
Second, as the number of intruded primary teeth which were followed-up until their permanent successors erupt was small, we could not statistically determine the effect of intrusive injuries on permanent successors development. Nonetheless, this study is significant in that a research on sequelae of permanent successors was carried out through long-term follow-up and in that this study determined factors influencing the outcome of intruded primary teeth and their successors. This retrospective study suggested that the severity of primary tooth intrusion can influence prognosis of permanent successor and when intrusion occurs with soft tissue injuries, traumatized primary tooth is likely to show favorable prognosis.
Based on trauma medical records, we collected data including clinical history, intraoral photographs and radiographic documentation of all patients. These data were organized according to age, gender, cause and site of trauma, severity of intrusion, other type of injuries accompanied at the time of injuries and complications during the follow-up periods in both primary and permanent dentition.
대상 데이터
Intrusion was commonly observed in primary maxillary central incisors (81%) with no difference between right and left teeth followed by primary maxillary lateral incisors (19%). 40 patients (65.6%) presented with a single affected tooth; 19 patients (31.1%) with 2 affected teeth; 2 patients (3.3%) with multiple affected teeth.
Of 176 children (249 teeth) who were diagnosed as primary tooth intrusion, 61 children (84 teeth) who met the inclusion criteria were evaluated. The mean age of these samples was 3.
3 years old and most prevalent age was 2 - 3 years in both boy and girl group. The final samples consisted of 40 (65.6%) boys and 21 (34.4%) girls. Intrusion occurred predominantly in males than in females, with a ratio of 1.

For the same reason, difference in incidence of primary tooth complication according to a type of accompanied injury was analyzed using Fisher’s exact test.
For the same reason, difference in incidence of primary tooth complication according to a type of accompanied injury was analyzed using Fisher’s exact test. On the other hand, effect of age and severity on primary tooth complication was statistically analyzed with Chi-square test.
성능/효과
First, since this study was performed retrospectively based on medcal records, there was a possibility that majority of complicated type of injuries were included in ‘intrusion only’ group.
In this study, 45 teeth (53.6%) of 84 teeth presented unfa vorable outcomes in the primary teeth during the periodical check-up. Borum and Andreasen[17] reported inflammatory root resorption accounted for 14% of complications in the primary teeth following intrusion.
Nonetheless, this study is significant in that a research on sequelae of permanent successors was carried out through long-term follow-up and in that this study determined factors influencing the outcome of intruded primary teeth and their successors. This retrospective study suggested that the severity of primary tooth intrusion can influence prognosis of permanent successor and when intrusion occurs with soft tissue injuries, traumatized primary tooth is likely to show favorable prognosis.
후속연구
Since the number of samples used in this study is limited, further studies with larger number of samples and longer follow-up period are needed.
