Contemporary endodontics has seen an unprecedented advance in technology and materials. This article aimed to review some of the challenges and advances in the following sections: (1) endodontic imaging, (2) root canal preparation, (3) root canal disinfection, (4) root canal filling, and (4) regenerative endodontic procedures (REPs). Jointly, these advances are aimed at improving the state of the art and science of root canal treatment.

“…The second category of the evaluation method focuses on the transportation of spatial centerline and the balance of periodontal dentin thickness. In [9, 16], root canal deviation and central positioning (or transportation) ability were considered to be essential parameters for evaluating the quality of canal preparation. In [33, 34], the thickness of the mesial and distal root canal wall was scanned and measured, respectively, and then the displacement and axial centrality of root canals in each group were calculated by using Gambill's formula.…”

“…Researchers have paid more and more attention to the issues of segmentation, registration, difference evaluation, and classification retrieval of 3D medical models. With the popularity of measurement tools represented by μ CT, the evaluation of anatomical structure before and after root canal preparation has become a hot topic in medical imaging [2–9].…”

“…To improve the effect of root canal therapy, various root canal preparation systems have been developed to maintain the original morphology of root canal anatomy (including using different instruments and cooperating with different solutions to eliminate the smear layer of the root canal wall). The results before and after the operation among groups were tested by the significance test, such as Mann–Whitney U test [3, 6, 7, 9]. With the development of medical imaging measurement technology such as CT, more and higher resolution image data can be collected, which boost more accurate instrument evaluation.…”

In recent years, we have seen more and more interest in the field of medical images and shape comparison motivated by the latest advances in microcomputed tomography (μCT) acquisition, modelling, and visualization technologies. Usually, biologists need to evaluate the effect of different root canal preparation systems. Current root canal preparation evaluation methods are based on the volume difference, area difference, and transportation of two root canals before and after treatment. The purpose of root canal preparation is to minimize the volume difference and ensure the complete removal of the smear layer. Previous methods can reflect some general geometric differences, but they are not enough to evaluate the quality of root canal shape. To solve this problem, we proposed a novel root canal evaluation method based on spectrum and eigenfunctions of Steklov operators, which can be served as a better alternative to current methods in root canal preparation evaluation. Firstly, the ideal root canal model was simulated according to the root canal model before and after preparation. Secondly, the Steklov spectrum of the two models was calculated. Thirdly, based on the spectrum and the histogram of the Gaussian curvature on the surface, the weight of each eigenvalue was computed. Therefore, the Steklov spectrum distance (SSD), which measures shape difference between the root canals, was defined. Finally, the calculation method that quantifies the root canal preparation effect of root canals was obtained. Through experiments, our method manifested high robustness and accuracy compared with existing state-of-the-art approaches. It also demonstrates the significance of our algorithm's advantages on a variety of challenging root canals through result comparison with counterpart methods.
