ProTaper Universal nickel titanium rotary file versus stainless-steel hand file: the security for root canal preparation

doi:10.3969/j.issn.2095-4344.2015.08.019

Abstract

Abstract:

BACKGROUND: The high number of tooth roots, complex root canal morphology, and bending and narrow trend require higher physical and mechanical properties for root canal preparation instruments.

OBJECTIVE: To evaluate the clinical efficacy of ProTaper Universal nickel titanium rotary file versus stainless-steel hand file for root canal preparation.

METHODS: A total of 100 patients with acute pulpitis teeth were randomly divided into experimental and control groups. In the experimental group, ProTaper Universal nickel titanium rotary file was used for root canal preparation, while in the control group, stainless-steel K-file (hand use) was used. Root canal preparation time, root canal curvature before and after root canal preparation and root canal filling quality were compared between the two groups.

RESULTS AND CONCLUSION: After root canal therapy, clinical symptoms were both improved in the two groups. Compared with the control group, in the experimental group, the root canal preparation time was significantly shorter (P < 0.05) and the root canal curvature varied more significantly (P < 0.05). In addition, the root canal filling quality was also superior in the experimental group to the control group. Therefore, ProTaper Universal nickel titanium rotary file is superior to conventional nickel-titanium endodontic file (hand use), which is easy to operate, saves both time and effort, and has good moldability, good security, high efficiency and excellent filling results.
