Abstract

>Aim: The aim and objective of this review is to present and discuss the characteristics of NiTi alloys and to present an overview on the variety of surface engineering techniques which may improve cyclic fatigue resistance, hardness and wear resistance while maintaining the torsional resistance and mechanical properties.

Methodology: A literature search for this narrative review was conducted in Google Scholar, PubMed and Web of Science using the keywords NiTi rotary instruments, cyclic fatigue, surface engineering techniques, surface treatment. Over 98 articles were found.

Result: Identification of over 98 studies for preliminary analysis. Articles unrelated to the surface treatment of NiTi instruments were excluded. The included articles were checked to identify further relevant literature. Overall, 25 articles were included up to 2021.

Conclusion: This review summarizes that there appears to be a risk of corrosion for NiTi instruments without surface treatments and also the cyclic fatigue resistance of NiTi files is influenced by the surface treatment. Thus by performing various surface engineering techniques, a smooth surface, from which machining defects were removed can be achieved. Hence, improved cyclic fatigue resistance, hardness and wear resistance while maintaining the life of the instruments can be achieved

Keywords: NiTi Rotary Instruments; Cyclic Fatigue; Surface Engineering Techniques; Torsional Resistance; and Mechanical properties
