초록
목적: 본 연구의 목적은 Passive Ultrasonic Irrigation (PUI) 적용 강도 및 적용 횟수에 따른 상아질 잔사 제거의 효율성 비교에 있다. 연구 재료 및 방법: 48개의 하악 소구치를 표준화하고 이등분 한 후, 한쪽 상아질벽에는 치근첨에서 1, 3, 5 mm의 거리에, 반대쪽 상아질벽에는 2, 4 mm의 거리에 함요를 형성하였다. 각 함요에 NaOCl과 혼합된 상아질 잔사를 채웠다. 치아는 PUI 적용 강도에 따라 ‘Weak’과 ‘Strong’의 2개 그룹으로 나누고(n = 24), PUI 적용 횟수에 따라 ‘1회’, ‘2회’, ‘3회’의 3개 그룹으로(n = 8) 다시 나누었다. 근관 세정 과정 이후 함요에 잔존하는 상아질 잔사의 양을 평가하였다. 결과: Weak 그룹과 Strong 그룹 간의 통계적 유의성은 관찰되지 않았다. Weak 그룹 내에서 PUI 적용 횟수에 따른 통계적 유의성 역시 관찰되지 않았다. 그러나 Strong 그룹에서 PUI를 2회, 3회 적용하였을 때, 1회의 경우보다 유의하게 낮은 상아질 잔사의 양이 관찰되었다. 결론: PUI 적용 강도에 따른 상아질 잔사 제거의 효율성은 통계적으로 유의한 차이가 없었다. 그러나 Strong 그룹에서 PUI를 다회 적용시, 1회 적용할 때 보다 근단 1/3 부위의 세정 효과가 증가한다.

Abstract
Purpose: The purpose of this study is comparing the efficiency of debris removal of passive ultrasonic irrigation depend on different protocols. Materials and Methods: Forty-eight mandibular premolars were randomly divided into 2 groups depend on vibration power (Weak and Strong, n = 24). And then two groups were subdivided into 3 groups depend on the number of times that PUI used (1, 2 and 3, n = 8). After standardization, teeth were split into two halves. On the wall of one half of root canal, three depressions were cut at 1, 3 and 5 mm from the apex and in the same way two depressions were cut on the other half of root canal at 2, 4 mm from the apex. Each depression was filled with mixture of dentine and NaOCl. After irrigation, images of the root canal wall were taken, and then the amount of remaining dentine debris was evaluated. Results: There was no significant difference between weak and strong power of vibration groups. Weak vibration groups did not show significant difference depend on the different number of times PUI used. But in the strong vibration groups, twice and three times used groups show better removal efficiency. Conclusion: The removal efficiency of dentine debris is not significantly different depend on the power of vibration. And multiple use of PUI could have better irrigating effects at the apical third area in the strong vibration group. (J Dent Rehabil Appl Sci 2020;36(2):104-11)
