초록

이 연구는 재생근관치료 결과에 영향을 줄 것으로 예상되는 인자를 후향적으로 분석하였다. 2011년 2월부터 2020년 1월까지 외상과 치외치 파절로 항생제 복합제제를 사용하여 재생근관치료를 시행한 54명의 환자와 57개의 치아를 대상으로 하였다. 의도적 출혈 여부, 치료원인, 치근발육단계에 따른 재생근관치료 결과를 분석하였다. 치료 결과는 증상의 개선, 치근단병소의 변화, 치근성장량을 토대로 판단하였다. 영상 촬영각도 및 위치에 의한 왜곡을 보정하기 위해 Turboreg plugin을 사용하였고, ImageJ softeware상에서 치근단공 크기, 치근면적, 치근길이의 변화를 측정하였다. 의도적 출혈 유무는 치료 결과에 유의한 영향이 없었다. 외상으로 인한 경우 치외치 파절로 인한 경우보다 치근면적과 치근길이의 증가가 적었다. 치근발육이 덜 진행된 치아일수록 치근면적의 성장이 크게 나타났다.

Abstract

This study retrospectively analyzed the effect of clinical factors on the outcomes of REP(regenerative endodontic procedure). Patients who received the REP using triple antibiotic paste due to trauma or fracture of dens evaginatus from February, 2011 to January, 2020 were included in the study. Finally, 57 teeth in 54 patients were selected. Investigated clinical factors were as follows: intentional bleeding, etiology, and root development stage. Treatment outcomes evaluated were as follows: improvement of subjective symptoms, changes in the periapical lesion, and the amounts of root development after REP. To compensate for differences in angulation and position between repeated radiographic examinations, images were aligned by Turboreg plugin. To evaluate the amounts of root development, apical diameter, root area, and root length were measured by ImageJ software. Among the aforementioned factors, intentional bleeding had no significant effect on treatment results. Regarding the etiology, the increase in the root area and the root length was significantly less in trauma cases than in dens evaginatus fracture cases. Considering root development stage, more immature teeth presented more increase in the root area.
