Abstract
Background: Oval shaped canals pose a challenge to endodontists. Self adjusting files have been introduced in the field of endodontics to overcome the deficiencies of rotary protapers in preparing oval canals.
Aims and Objectives: To evaluate the cleaning efficiency of rotary protaper along with endoactivator and self adjusting file in oval shaped canals using scanning electron microscope.
Materials and Methods: 20 single rooted mandibular premolars were divided into 2 groups of 10 in each group. The root canals were instrumented with rotary protaper and self adjusting file. Teeth were sectioned longitudinally in mesiodistal direction and buccal and lingual aspects evaluated by scanning electron microscope.
Results: Comparison of mean values among the groups was done using Mann-Whitney U test. SAF performed better in middle third than rotary protaper with significant difference and there was no significant difference between SAF and rotary protaper in the apical third region.
Conclusion: SAF is more effective than rotary protaper in cleaning the long oval shaped canals.
Keywords: Oval canals, ProTaper, Self-adjusting file, scanning electron microscope, sodium hypochlorite.
