Efficacy of Two Nickel-Titanium Rotary Root Canal Instruments compared with Different Instruments in Endodontic Treatment: A Systematic Review

Abstract

The success of endodontic treatment depends on root canal preparation which is extremely important during the root canal treatment. The root canal instrumentation phase by using nickel-titanium instruments will help in the effectiveness of other procedures, such as facilitating irrigation and aspiration and three-dimensional obturation of canals. The objective of this review reviews all the data in regards to the efficiency of two nickel-titanium rotary instruments which are pro-taper next files and pro-taper universal files compared with different instruments in endodontics and which conducts are most used and appropriate for optimal root canal instrumentation. For such, we carried out a systematic review of the literature, using all the databases included in PubMed and Google Scholar. The search retrieved 401 articles, of which, after applying the exclusion/inclusion and quality criteria, 12 articles were selected for an in-depth analysis. Among the main results, we highlight two nickel-titanium rotary instruments that were used to aid the cleaning and shaping in root canal treatment, in addition to presenting several aspects such as different types of instrument systems, the efficiency of instruments during cleaning and shaping, and updating studies of their effect in the root canal treatment and re-treatment. This review concluded the rotary instrumentations especially pro-taper next files and pro-taper universal files illustrated great cleaning efficiency during root canal treatment and root canal re-treatment compared with hand stainless steel files and different instruments.
