ABSTRACT

Successful root canal therapy depends on many factors. One of the most important steps in any root canal treatment is biomechanical preparation. Additionally, respecting the original shape of the canal is of the same importance. Otherwise, canal aberrations such as transportation will be created. Purpose: To evaluate the canal transportation and canal centering ability of ProTaper Next (PTN), TruNatomy (TN), and Neohybrid (NH) file systems using cone-beam computed tomography. Materials and methods: Thirty extracted single-rooted mandibular premolars were decoronated and divided into three experimental groups, with ten in each group. Group I - ProTaper Next (PTN), Group II - TruNatomy (TN), and Group III - Neohybrid (NH) file systems. Cone-beam computed tomographic pre-scan were taken, followed by biomechanical preparation with the respective file systems. Post CBCT scans were taken and compared with pre-scans for canal transportation and canal centering ability at the levels of 3, 6, and 9mm. The data obtained were statistically analyzed. Results: Using One way ANOVA and Post hoc analysis, canal transportation at the level of 6mm from the apex, group II and group III have shown statistical significance compared to group I, and no statistically significant differences were seen at the levels of 3mm and 9mm. There is no statistically significant difference in canal centering ability among the three groups at the levels of 3,6, and 9mm from the apex. Conclusion: Under the in vitro conditions of the study, ProTaper Next (PTN), Trunatomy (TN), and Neohybrid (NH) rotary systems have shown similar behavior concerning canal transportation and canal centering ability.
