Abstract

Aim: The aim of this study is to compare microcrack formation and propagation in apical one third of root after retreatment, while using two different retreatment files.

Material and Methodology: A total of 50 human mandibular premolar teeth with straight root canals were selected and coronal third enlargement done with one flare. The biomechanical preparation of the teeth were done using Protaper Next rotary files X1 and X2. Obturated using gutta-percha with AH Plus sealer by lateral condensation technique. The samples were divided into two retreatment groups -Group I- Protaper Universal Retreatment file system and Group II-Wave One Gold primary File. Then microcracks were assessed using scanning electron microscope. The data were statistically analysed using Pearson Chi square test, Odd’s ratio and Relative risk/Risk ratio.

Results: After retreatment, microcracks are present in both the groups. The PTUR system caused significantly more microcracks than the Wave one gold file system in the apical one third of root.

Conclusion: Within the limitations of present study, continuous motion file group produced significantly more percentage of incidence and propagation of dentinal microcracks as compared to reciprocation motion file group.
