| Abstract | ||||
| Purpose: the purpose of this study is to investigate the incidence of dentinal crack formation after root canal preparation using ProTaper Next, ProTaper Gold and TruNatomy rotary files. Material and methods: ninety five extracted human lower first molars were collected. Teeth were divided into 1 control group consisting of 5 teeth and 3 experimental with 30 samples in each experimental group. Root canal preparation was done with ProTaper Next, ProTaper Gold and TruNatomy files in the mesio-buccal canal. Then mesial roots were sectioned at 3mm, 6mm, and 9mm from the apex and examined under a stereomicroscope. The data were analyzed using Chi- Square test. Results: No cracks were observed in the control group. TruNatomy file produced less crack in compare to ProTaper Gold and ProTaper Next. Dentinal cracks occurred more in the middle and apical thirds in compare to coronal third. Conclusion: ProTaper Next tends to produce more crack in compare to ProTaper Gold and TruNatomy files. | ||||
