Comparison of apical microleakage during root canal therapy by K-type files and Flex-R files
AUTHOR(S): Pinky Singh and Sanjay Kumar Singh
Canal-shaping is a critical aspect of endodontic treatment because it influences the outcome of the subsequent phases of canal irrigation, filling, and the overall success of the treatment itself. Hence; the present study was undertaken for assessing and comparing apical microleakage dentinal changes during root canal therapy by K-type files and Flex-R files.
Materials & Methods: 20 freshly extracted maxillary second premolars were obtained and included in the study. All the tooth specimens were cut from the cement-enamel junction. All the specimens were divided into two study groups depending upon the type of file used, with 10 specimens in each group. Only those teeth were selected which had a straight distal canal. If the apical foramen was open to over # 20 K file the tooth was rejected. The teeth were cleaned and stored in normal saline for 1 week. Working length was assessed radiographically and biochemical preparation was done according to the specific group. After completing the biochemical preparation, microleakage was assessed using stereomicroscope.
Results: Mean microleakage of the K-type file group was 3.7452 and mean microleakage of the Flex- R file was 2.9650. Significant results were obtained while comparing the mean microleakage among the K-type file group and Flex-R file group.
Conclusion: From the above results, the authors conclude that Flex- R file are better in comparison to K-type files.
