• Abstract: This study proposed to demonstrate a technique to calculate root canal curvature on 2D and 3D images using point coordinate, named Point Method (PM), and further compare these methods to the most used method (Schneider). The total sample comprised 120 teeth (30 upper lateral incisors, 30 lower premolars, 30 upper molars, and 30 lower molars), with no radiopaque material on the root canal or pulp chamber. Each tooth underwent periapical radiograph and CBCT exams, and the curvature was analyzed by three different methods - Schneider, 2D PM, and 3D PM. Schneider and 2D PM were performed on periapical radiograph and 3D PM on CBCT. Point Method analysis was made placing points on the canal lumen with a vertical distance of 1mm among points. Using open-source software, the coordinates for each point were transferred into a spreadsheet with analytical geometry formulas. A repeated measures test was made to compare angular values among the methods and an independent measures test was performed to compare the dental groups and the root thirds. The mean curvature angle values found using 3D PM (89.01°) were significantly higher when compared to 2D PM (56.72°) and Schneider (34.62°) for all dental groups. Multirooted teeth had a greater mean curvature angle than single-rooted and the apical third also presented the most curved root canals amongst the root thirds. The results presented herein show that 3D curvature was higher when compared with 2D analysis. Higher curvature angle values were found at the apical third and on multirooted teeth
