“…Moreover, EdgeFile system had an Effect of Different Contemporary Rotary Nickel Titanium Systems on Root Canal Geometry (533) outstanding capability in shaping curved canals than other rotary systems. The file metallurgy and design features could be responsible for these findings which were consistent with previous reports (17)(18)(19)(20) .…”

Purpose: This study aimed to compare NiTi rotary systems of different wires namely; EdgeFiles, Profile GT series X (GTX) and ProTaper (PT) in terms of: canal transportation and centering ability. Materials and Methods: One hundred and twenty extracted human mandibular first molars were selected and randomly divided into two main groups (I&II) according to the ranges of curvature (60 teeth each), where group I: samples with 25º-40º range of curvature and group II: samples with 45º-60º range of curvature. Each group was subdivided into four subgroups according to the NiTi rotary system (15 teeth each): subgroup A: ProTaper, subgroup B: Profile GT Series X, subgroup C: EdgeFile X3 and subgroup D: EdgeFile X5. The root canals were scanned by i -CAT CBCT scanner before and after instrumentation at 3, 5 and 8 mm levels from the apex, to assess the canal transportation and centering ability. Results: The EdgeFile system produced the least canal transportation and remained more centered around the original canal than the other systems. While, PT system produced significantly the highest canal transportation and the least centered canal preparation than other systems. Conclusions: EdgeFile systems showed superior performance regarding maintenance of the original root canal curvature and centering ability than do other systems.

“…The comparison of means from different measurements was commonly used for the evaluation of accuracy between different methods [3,11]. The results from these two studies revealed that there were significant differences between the means from different methods of evaluation, preventing further comparisons among the methods [3,11]. The result of the present study revealed that there was an agreement between both methods using periapical digital radiography and CBCT in the evaluation of root canal transportation with the same levels of investigation.…”

The aim of the present study is to compare cone beam computed tomography and periapical digital radiography for the evaluation of root canal preparation. Nine extracted human molars were used in this study. Following access cavity preparation, mesio-buccal roots of maxillary and mesial roots of mandibular molars were prepared and the remaining roots were cut off. Three amalgam cavities were prepared on the coronal part of the teeth and were filled with amalgam to be used as landmarks. Specimens were scanned using cone-beam computed tomography and periapical digital radiograph images were obtained before and after root canal preparation. WaveOne Gold Primary was used for root canal preparation to full working length. Specimens were then scanned using CBCT and a periapical radiograph for the after-instrumentation images. The transportation and centering ratio were measured and calculated on the CBCT and periapical radiographic images. The Bland–Altman method was used for detecting the bias in the evaluation of agreement between the two methods’ measurements. There was agreement between the two methods’ measurements using CBCT scans and periapical digital radiographic images in the evaluation of transportation and centering ratio parameters. The two methods could be used interchangeably in measurements of transportation and calculating the centering ratio.
