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, Hyex 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, Hyex 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 magnication 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 signicant difference between Protaper Universal group and Control, Hyex CM and WaveOne group (p<0.05) with Protaper universal group showing maximum cracks and Hyex CM and Wave One showing least number of cracks. No signicant difference was found between Protaper Next, Hyex CM and WaveOne group (p>0.05). Conclusion: Within limitations of the study, it can be concluded that Protaper Universal, Protaper Next, Hyex CM and WaveOne systems results in dentinal crack formation after instrumentation in roots canals
