Comparative Analysis of Efficacy of Mtwo NiTi Rotary Files and Hand K-files
Journal Title: Journal of Advanced Medical and Dental Sciences Research - Year 2017, Vol 5, Issue 12
Abstract
Background: The advantages of rotary NiTi instruments over hand instruments include facilitating canal preparation, preserving the shape of curved canals and producing smooth surfaces in lesser time than with manual instruments. Aim of study: To compare efficacy of MtwoNiTi rotary files and Hand K-files. Materials and methods: The study was conducted in the Department of Conservative Dentistry of the Dental institution. We selected 40 extracted first mandibular molars. The teeth were randomly grouped into two groups, Group A and Group B with 20 teeth in each group. The instrumentation of specimens of the Group A was done using stainless steel K-files and in Group B was done using MtwoNiTi rotary files. The working length of the root canals was standardized at 20 mm. The cleared specimens were viewed under stereo microscope at 10X for checking the amount of residual india ink at coronal, middle and apical region of the canals and scored from 0 to 3. Score 0 was awarded to wholly clean canal, 1 was awarded to hardly any ink residues, 2 was awarded to incomplete ink removal and 3 was awarded to no ink removal. The results were evaluated. Results: We observed that in case of K-files, highest frequency was seen in score 1 followed by score 0. In case of Mtwo files, highest frequency was seen in score 0 followed by score 1. On comparing the results significant results were obtained. Conclusion: MtwoNiTi rotary files were more efficient in cleaning tooth root canals
