Background:
Canal transportation is a common sequel caused by rotary instruments.
Aims:
The purpose of the present study is to evaluate the degree of transportation after the use of Reciproc single-file instruments with or without glide path files.
Methods:
Thirty resin blocks with L-shaped canals were divided into three groups (n = 10). Group 1 - canals were prepared with Reciproc-25 file. Group 2 - glide path file-G1 was used before Reciproc. Group 3 - glide path files-G1 and G2 were used before Reciproc. Pre- and post-instrumentation images were superimposed under microscope, and resin removed from the inner and outer surfaces of the root canal was calculated throughout 10 points.
Results:
Statistical analysis was performed with Kruskal-Wallis test and post hoc Dunn test. For coronal and middle one-thirds, there was no significant difference among groups (P > 0.05). For apical section, transportation of Group 1 was significantly higher than other groups (P < 0.05).
Conclusion:
Using glide path files before Reciproc single-file system reduced the degree of apical canal transportation.
