| Abstract | ||||
| Objective: The purpose of the current study was to compare the cleaning efficiency of single file system (AF F ONE) to a multiple file system (ProTaper Next) (PTN) in oval-shaped root canals. Material and methods: Eighteen extracted human mandibular premolar teeth with single oval canal were collected. Decoronation of teeth was performed to achieve a standardized root length of 14 mm. Then, random allocation of teeth into two groups was done according to NiTi rotary system used as follows; group I (PTN), group II (AF F ONE). After root canal preparation, roots were longitudinally sectioned into 2 halves. The most visible half was selected and the amount of debris in coronal, middle and apical thirds was assessed by using a stereomicroscope (Ziess technival 2, Germany) at 25X magnification. The percentage of the remaining debris in each third was then calculated by dividing the areas covered by the remaining debris by the total area of each third multiplied by 100. Results: There was no statistically significant difference between debris percentage following the use of both files at coronal and middle thirds respectively. However, at the apical third, ProTaper Next showed statistically significant lower debris percentage than AF F ONE. Conclusion: It could be concluded that ProTaper Next rotary file system had better cleaning efficiency than AF F ONE single file rotary system in oval canals. | ||||
