Abstract

Aim and Objective: This study aimed to compare and evaluate the amount of remaining dentin thickness in cervical, middle and apical third after instrumentation with stainless steel k -file [Hand instrumentation] and Neo Endo flex rotary file system by using Cone-beam computed tomography (CBCT).

Materials and Methodology: Ten freshly extracted human mandibular single-rooted teeth were selected. IOPA of all the teeth were taken to know the internal morphology. Teeth with simple morphology and single straight root canal were selected. Teeth were randomly assigned to two groups of five samples each. group1: k-file (stainless steel hand instrumentation) group 2: Neo Endo flex (rotary file system). Pre instrumentation cbct scan was taken for two groups by stabilizing the samples on wax blocks. Dentin thickness values measured at the cervical, middle, and apical third. The Access cavity was prepared, and canal patency was checked using 10 k-file by placing the file up to apical foramen. Working length was determined using the same file1 mm short of the apical foramen. Root canal instrumentation was done in two groups with hand files and rotary file system respectively, according to the manufacturer’s instructions. Finally, root canals were irrigated with 2 ml of normal saline. Postoperative cbct scan was taken for two groups at cervical, middle, and apical third.

Results: Statistically, a significant difference was observed between the two groups. The k- file (stainless steel) hand instrumentation system removed more amount of dentine than that of Neo Endo flex (P > 0.05).

Conclusion: Stainless steel k-type file (Hand instrumentation) files showed more remaining dentin thickness than Neo Endo rotary files (Rotary file system).
