Abstract

Objective: Evaluation of endodontic treatment results of lower molars using Jizai rotary file system. Research subjects and methods: 45 mandibular molars with irreversible pulpitis indicated for endodontic treatment were included in a non-randomized clinical intervention study. Results: The average root canal shaping time was 28.87 ± 5.15 minutes, the fastest shaping time was 18 minutes, the longest was 39 minutes. There were no complications during the root canal preparation process. After 6 months of filling, the success rate was 95.56%; doubtful rate was 4.44%. There were no cases of failure. Conclusion: Shaping with Jizai rotary file significantly shortens working time compared to traditional hand file system, is safe, has no complications and gives initial successful results with high rate.
