Abstract

Introduction: Aim of the study was to observe and compare the dentinal cracks caused by instrumentation of root canal with rotary Protaper Universal, Protaper Next, Hyex CM and WaveOne systems. Methods: One hundred ten mandibular premolars with mature apex and straight single canals (<10°) were selected and stored in distilled water. Root canals were divided into control (uninstrumented) group (n=10), 4 experimental groups (n=25) instrumented with Protaper Universal, Protaper Next, Hyex CM, and WaveOne. Root canals were stained with 1% methylene blue dye and horizontal sectioning was done at 3mm, 6mm and 9mm from apex and viewed under 30-fold magnication of stereomicroscope and digital images were captured using camera attached to it to determine presence of dentinal cracks. Data was analysed using chi-square test. Results: The control group showed no cracks. All experimental groups showed presence of dentinal cracks. There were signicant difference between Protaper Universal group and Control, Hyex CM and WaveOne group (p<0.05) with Protaper universal group showing maximum cracks and Hyex CM and Wave One showing least number of cracks. No signicant difference was found between Protaper Next, Hyex CM and WaveOne group (p>0.05). Conclusion: Within limitations of the study, it can be concluded that Protaper Universal, Protaper Next, Hyex CM and WaveOne systems results in dentinal crack formation after instrumentation in roots canals
