COMPARISON OF THE CLEANING EFFICACY OF TWO NITI FILE SYSTEMS
Main Article Content
Abstract
Objectives: To compare the cleaning efficiency of two relatively new NiTi rotary instrument systems. Methods: Forty freshly extracted mandibular premolars were equally divided into two groups: WOG group prepared by WaveOne Gold file, PTN group prepared by Protaper Next file. These teeth were sectioned longitudinally and processed for evaluation of debris and smear layer score under Scanning Electronic Microscope at 2 mm, 5 mm and 8mm from the apex by two observers. Results: There were statistically significant differences between two groups in debris scores overall, in the middle third and in the cervical third (p<0,05). Conclusion: The Protaper next file system is more efficacious than WaveOne Gold system in terms of cleaning debris overall, middle and cervical third.
