Abstract
이 연구의 목적은 소아 및 청소년의 영구치 치관 파절시 파절편 재부착술의 추적 관찰 결과를 평가하고자 함에 있다. 21명의 27 개의 영구치 파절편 재부착술을 시행한 환자를 대상으로 임상 사진, 방사선 사진 및 의무기록을 활용하여 평가하였다. 파절편 탈락은 총 17개 치아에서 관찰되었으며 반복적인 외상이 가장 빈번한 실패 원인이었다. 파절편 재부착술과 치수치료 시행 유무는 통계적으로 유의미하지 않았다(p > 0.05). 평균 파절편 비율은 0.482 ± 0.147이며 성공률은 파절편 비율과 유의미한 상관관계를 나타냈다(p = 0.018). 평균 파절편 유지 기간은 72개월이며 파절편 유지 기간과 파절편의 비율은 통계적으로 유의미한 상관관계를 나타냈다(p = 0.003). 소아 및 청소년의 영구치 치관 파절시 파절편 비율이 50% 미만인 환자에서 파절편 재부착술은 예측 가능한 치료 방법이 될 수있다고 판단된다.
This study aimed to evaluate the long-term outcomes of teeth treated with reattachment technique in children and adolescents. Twenty seven permanent anterior teeth from 21 patients treated with fragment reattachment were evaluated. Clinical photos and medical records were used to assess treatment outcomes. Effect of pulp treatment and the ratio of fragment on success rate were statistically analyzed. Detachment of fragment was observed in 17 teeth, and their duration of retention was 21.41 ± 23.39 months. Repeated trauma was found to be the most frequent causes of failure.
Pulp treatment before reattachment did not affect the success rate (p > 0.05). The mean ratio of fragment was 0.482 ± 0.147, and the success rate was affected by the ratio of fragment (p = 0.018). The median retention time of the teeth was 72 months if the ratio was under 0.5, and 8 months for that of the others. A significant correlation was found between the ratio of fragment and retention time (p = 0.003). Reattachment can be a predictable treatment option for crown fracture in anterior teeth in children and adolescents when a fracture involves less than 50% of the clinical crown.
