Effect of Using Rotational and Reciprocating Single File Systems with Different Tapered Coronal Flaring Instruments on Dentinal Crack Formation: An In Vitro Study
نویسندگان
چکیده
Objective: The purpose of this study was to evaluate the effect using single-file with different tapered coronal flaring files on dentinal crack. Material and Methods: Human extracted mandibular premolars (n=128) were selected divided into four groups (n=32) based instruments; Group 1, One Flare; 2, Endoflare; 3, Gates Glidden Drills; 4, Control Group. Specimens subgroups single file system (n=8): Subgroup A, HyFlex EDM: B, Reciproc Blue: C, Shape: D, WaveOne Gold. All roots then sectioned at 6, 9 mm from apex. sections inspected under a stereo-microscope 2.5X 5X determine presence microcracks. data analyzed chi-square test (p=0.05). Results: There no statistically significant difference between distributions cracks caused by use systems (p>0.05). according also Conclusion: instruments combinations reduced observation dentin cracks. Flare less than other test.
