A comparison of canal centering ability of four instrumentation techniques

The efficiency of the Ni-Ti rotary files in curved simulated canals shaped by novice operators

“…Kavanagh and Lumley 22) and Bryant et al 20) found that the use of Ni-Ti rotary instruments was effective and produced good canal shapes. Other studies 23,24) partly supported their observations. Gluskin et al 25) found that novice dental students were able to prepare curved root canals with Ni-Ti rotary files with less transportation and greater conservation of tooth structure, compared to canals prepared with hand instruments.…”

Comparison of Canal Transportation and Centering Ability of K-files, ProGlider File, and G-Files: A Micro-Computed Tomography Study of Curved Root Canals

“…Flexibility may influence the instrument's ability to properly shape curved root canals. Several studies have shown that more flexible instruments produce more centered preparations (11,31). The ProGlider file used in this study is manufactured from M-wire NiTi alloy while G-Files are made from conventional NiTi.…”

A study on transportation of apical foramen after overinstrumentation by ProFile®, ProTaper™ and K3TMin simulated canals with different curvatures

“…좁고 만곡 된 근관에서 기존의 스테인레스 스틸 파일 보다 Ni-Ti 파일을 이용한 근관 성형이 근관의 원래형태를 유지 하고 렛지와 천공 등의 근관 변이를 덜 유발하는 것으로 알 려진 이래 [14][15][16] 다양한 종류의 파일이 개발되었고 그 효율성 과 안전성 및 근관 삭제능력 등에 대한 많은 연구가 진행되 어 왔다 [17][18][19] . 근관의 변이는 파일의 구조와 관련이 있다 20) .…”
