Comparative Evaluation of Two Different Rotary Systems in the Removal of Debris in Apical Third of the Root Canal: An in Vitro Study

Dr. Kanchan Hegde | Dr. Ashwini Gaikwad

Abstract: Aim: The aim of the present study is to evaluate and compare the cleaning efficacy of teeth instrumented with ProTaper Next and Self Adjusting File system. Methodology: 45 permanent mandibular premolar teeth with single canal were selected and divided into 3 groups (n=15). One positive control group, one group was instrument with SAF file system while the other with PTN system. The tooth were histologically processed and serial cross-sections were obtained from apical levels. Morphometric evaluation was performed and the percentage of remaining pulp tissue area (PRPT) was calculated for each root canal. Statistical analysis: The non parametric test and Mann Whitney U test were used. Results: No statistical significant difference was found between the two groups (SAF and PTN file system) in their debridement efficacy in the apical third of root canals. Conclusion: Both file systems were efficient in removing the debris from the apical third of the root canals but none of the rotary systems could remove the debris completely.
