Abstract		Introduction A comparison between root canal transportation studies is nearly impossible due to non-standardized transportation evaluation methods. The aim of the present review was to search, compare, and critically discuss transportation evaluation methods. Methods A search of PubMed, Web of Science, Scopus, ScienceDirect, and reference lists of articles was conducted up to March 2020 using appropriate keywords to identify transportation evaluation methods. The methods in the included articles were extracted, compared, and categorized. Results Seventy-four articles using original methods were selected. All studies share three main steps: image acquisition, image measurements, and calculation of parameters. Images were acquired by photography, radiography, and computed tomography. Two types of measurements were used: the amount of removed material and canal center point distance. The parameters were calculated and reported as distance or ratio. Relationships between the different transportation parameters were found and confirmed with mathematical simulation. Conclusions Although methods were proposed as being novel, similarities between them were found, enabling the classification of the methods and identifying correlations. The canal center point distance is the most suitable for the description of canal transportation as it is comprehensible, and it relates to the mathematical concept of translation. Removed material based measurements are double the value of canal center point distance. Ratio parameters are not suitable for reporting transportation.
