어떤 싱글파일, 레시프로케이팅 파일이 근관중심을 잘 유지하나? Canal Transportaion Test

가장 대표적인 싱글파일(Reciprocating file) 시스템은 덴츠플라이의 웨이브원, VDW의 레시프록입니다.

그러나 같은 티타늄알로이라 하여도 열처리나 제조공정에 따라 물적인 특성이 제각각입니다.

 

아래는 에지엔도의 Fire-Wire 열처러 NiTi 파일인 EdgeFile X1과 WaveOne, Reciproc을 비교한 논문입니다.

에지엔도의 에지파일 엑스원이 가장 뛰어납니다. 그이유는 아마도 에지엔도의 열처리방식때문일 것입니다.

세가지 파일중 에지엔도의 나이타이파일이 유연성이 가장 뛰어납니다.

Abstract

Introduction: The purpose of this study was to compare canal transportation and the centering ability of Reciproc (VDW, Munich, Germany), WaveOne (Dentsply Maillefer, Ballaigues, Switzerland), and EdgeFile (EdgeEndo, Albuquerque, NM) rotary systems using cone-beam computed tomographic imaging.

Methods: Ninety mesiobuccal mandibular first molar uncalcified canals with at least a 19-mm length, a canal curvature of 15°-30° (the Schneider method), and a mature apex were selected. Canals were randomly divided into 3 groups of 30 teeth, and canal preparation with the Reciproc, WaveOne, and EdgeFile systems was performed according to the manufacturers' instructions. Cone-beam computed tomographic images were taken before and after instrumentation in the same position. Apical transportation was calculated in the distances of 2, 3, and 4 mm from the apex. Kruskal-Wallis and Mann-Whitney U tests were used to statistically analyze the data.

Results: The mean canal transportation was significantly lower with EdgeFile (P < .001) followed by the WaveOne rotary system. Moreover, the centering ability of the EdgeFile system was higher than that of the WaveOne and Reciproc systems.

Conclusions: The EdgeFile rotary system showed the lowest transportation in both the mesiodistal and buccolingual directions and the highest centering ability. The Reciproc system showed the highest transportation and the lowest centering ability.

Keywords: EdgeFile; Reciproc; WaveOne; single file; transportation.
