Abstract

The aim of this study was to evaluate the factors affecting the healing of root fracture in immature permanent teeth and the prognosis of root fracture by statistically analyzing the relationship with the pulp and root healing. The radiographs of 51 root-fractured maxillary anterior permanent teeth were collected. In radiograph, locations of root fracture, apical foramen width and width of diastasis between the fragments were measured. The value of the studied parameters were compared by independent t-test and rogistic regression test. In conclusion, there was no difference in the prognosis of pulp healing according to the location of root fracture. However, root healing occurs well as the root fracture is located at the root apex (p < 0.05). Lastly, the smaller the width of diastasis between the fragments after reduction, the better the pulp healing was (p < 0.05).

본 연구는 미성숙 영구치에서 치근 파절 시 치수와 치근 치유에 영향을 주는 요인을 평가하기 위해 치근 파절위치, 치근단공의 크기, 파절편 간격을 측정하였고, 치수와 치근 치유 양상과의 연관성을 통계적으로 분석하여 치근 파절시 예후를 알아보고자 하였다. 51개의 상악 전치부 치근 파절 증례를 대상으로 치근 파절위치, 치근단공의 크기, 파절편 간격을 방사선 사진에서 길이를 측정하였다. 측정된 수치는 독립 T검증, 로지스틱 회귀분석을 통해 평가하였다. 본 연구의 결과, 치근 파절의 위치에 따른 치수 치유의 예후의 차이는 없었다. 그러나 치근 파절의 위치가 치근단에 위치할수록 치근 치유는 잘 일어났으며(p < 0.05), 정복 후 파절편 간격이 좁을수록 치수 치유가 잘 일어남을 확인하였다(p < 0.05).
